The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art.
According to research, when SIc is smaller than 1, macroscopic calcium bloom deposition is actively slow, when SIc is larger than 1.1-1.2, new calcium bloom deposition is obvious, a remarkable deposition boundary line can be provided for SIc index control. SIc =1.2 has uniform control function in yellow dragon confetti pond and yellow dragon moon confetti pond, is generally the starting point of high-quality calcareous landscape, SIc is more than 1.4, and calcareous is extremely strongly deposited, and is visible in pond group at the downstream of yellow dragon confetti pond.
When the density and the grain diameter of calcium carbonate particles in water are in a low level, the natural deposition rate of the calcium bloom is low, the deposition capability of the calcium bloom is poor, and when the calcium carbonate particles are used for controlling the rapid formation of the new calcium bloom, in-situ strengthening treatment is required to be carried out on source water.
According to the in-situ test results of the yellow dragon scenic spot, the temperature, the flow rate, the flow state, the ultrasonic wave, the diatom and the like have better effects on the quality improvement of the calcium bloom source water, and are used as the technical basis of the application of the invention.
In this embodiment, the case of the research project of repairing calcium bloom in the yellow dragon scenic spot and the immortal pool scenic spot in Sichuan province is taken as an example, and the yellow dragon scenic spot has obvious quality degradation phenomenon due to the prominent degradation problems of calcium bloom blackening, desertification, strong leakage and the like, so that part of calcium bloom scenic spots are displayed. The calcium bloom blackification is caused by water loss and serious secondary problems caused by weathering, loose calcium bloom is formed, poor calcium bloom deposition is caused by extremely low index SIc, poor flow state (Fr < 1 forms subcritical flow), extremely low concentration of calcium carbonate particles in water and the like, the cementation capability of the calcium bloom deposition is extremely poor, strong leakage is caused by the fact that a shrub root system breaks the calcium bloom structure, and algae breeding is mainly caused by excitation of algae proliferation by blade leaching, low SIc index, strong degassing zone activity and the like.
The application provides a device and a method for strengthening the source water of calcium bloom deposition in order to repair the degraded calcium bloom landscape of a yellow dragon scenic spot in Sichuan province, which can form the source water with extremely high calcium bloom deposition capacity by in-situ transformation according to the basic principle that the natural attribute and natural recovery of the landscape are not affected so as to scientifically, safely, quickly and effectively form new natural calcium bloom.

The first water pump 1 is connected with the high flow rate strengthening unit 2 through a water pipe 7, the water pipe 7 adopts a wear-resistant steel wire hose, and an electromagnetic flowmeter 8 is further arranged on the water pipe 7. The water pump 1 pumps the water in the raw water tank into the high-flow-rate strengthening unit 2, and the high-flow-rate strengthening unit 2 is arranged at the downstream position of the water pump 1 and is used for limiting the water flow and strengthening the water flow rate, so that the density and the particle size of calcium carbonate particles in the water flow are increased, and the primary strengthening is realized.
Referring to fig. 2-4, the high flow rate strengthening unit 2 includes a diversion box 21, the diversion box 21 is a closed box body and is made of transparent acrylic plates, a water inlet is formed in one side of the diversion box 21, a first water pump 1 is connected with the water inlet of the diversion box 21 through a water pipe 7, and the first water pump 1 pumps water in a source water pool into the diversion box 21. The other side of the shunt box 21 is provided with a plurality of water outlets, each water outlet is in butt joint with a shunt tube 22, and the number and caliber of the shunt tubes 22 are adjusted according to actual needs, so that the particle size and density of calcium carbonate in water flow are obviously increased to be standard. The water in the shunt box 21 enters the shunt tube 22 to realize the shunt. The water outlet of the shunt tube 22 is connected with a shrinkage tube 23, the shrinkage tube 23 is used for improving the water flow speed, the caliber of the reinforced shrinkage tube 23 is set according to actual needs, and the standard is that the particle size and the density of calcium carbonate in water flow are obviously increased.
The shrinkage tube 23 is of three types, namely a straight tube, a coiled tube and an M-shaped bent tube with gradually changed thickness, and any one of the three types can be selected according to the needs when the shrinkage tube is used, or a combination of the three types can be selected for use. The coiled pipe and the M-shaped bent pipe-shaped shrinkage pipe 23 are generally applied to a water body with very slow growth of the natural-flow underwater newly-grown calcium bloom. The water outlet of the shrinkage tube 23 is connected with a water collection tank 24, and the water collection tank 24 collects the water flow with the flow rate strengthened therein.
The high flow rate strengthening unit 2 limits the water flow, so that the water flow rate is quickly accelerated in the shrinkage tube 23, the average particle size and the density of the calcium carbonate particles in the water are synergistically increased and decreased along with the increase of the flow rate, and the average particle size and the density of the particles in the water are simultaneously increased in the range of 0.5-2.0 m/s. In order to further expand the repair field, a plurality of high flow rate reinforcing units 2 may be provided as needed.
Referring to fig. 5-8, after performing particle size statistics on SEM photographs of calcium carbonate particles in water at different flow rates, it is known that the characteristics of the experimental results of each gradient of the flow rates are consistent, and the particle size distribution of the particles in water accords with the Gauss distribution characteristics.
Wherein, the particle size of calcium carbonate in water is smaller than 2 μm at the flow rate of 0.5m/s in FIG. 5, the average particle size of 1.07 μm in water, the particle size of 98.0% of calcium carbonate in water is smaller than 3.5 μm at the flow rate of 1.0m/s in FIG. 6, the average particle size of 1.2 μm in FIG. 7, the particle size of 96.9% of calcium carbonate in water is smaller than 4 μm at the flow rate of 1.5m/s in FIG. 7, the average particle size of 2.45 μm in FIG. 8, the particle size of 96.6% of calcium carbonate in water is smaller than 4 μm at the flow rate of 2.0m/s in FIG. 8, and the average particle size of 2.23 μm in water.
Therefore, the characteristics that the average particle size and the content of the calcium carbonate particles in water are increased and decreased in a synergic manner are verified along with the increase of the flow rate, the average particle size and the content of the particles in water are increased and decreased at the same time in the range of 0.5-2.0 m/s of the flow rate, and the maximum value of the deposition capacity (SIc) is also generated in LS-3 (1.5 m/s), namely, the deposition capacity of a calcium bloom water body is improved when the flow rate is increased in a certain range, the content of the particles in water is increased, and the particle size of the particles in water is increased.
The temperature strengthening unit 3 is arranged at the downstream of the high flow rate strengthening unit 2 and is connected with the water collecting tank 24 through the water pipe 7, the water flow strengthened by the high flow rate contains a large amount of calcium carbonate particles, the water flow enters the temperature strengthening unit 3, the temperature strengthening unit 3 strengthens the temperature of the water flow, the calcium water body realizes strong CO 2 degassing, the concentration of Ca 2+ and HCO 3 - in the source water is rapidly reduced, the pH and the SIc are rapidly increased, and the density and the particle size of the calcium carbonate particles in the water are further improved.
Referring to fig. 9, the temperature strengthening unit 3 includes at least one heating rod 31, and the number of the heating rods 31 can be adjusted according to actual needs, and in this embodiment, three heating rods 31 are taken as an example.
The outer cover of the heating rod 31 is provided with a support tube 32, the support tube 32 is made of UPVC material, a plurality of water permeable holes 33 are formed in the surface of the support tube 32, water continuously enters the inside of the support tube 32 from the inlet end and then flows out from the outlet end, and in the process, the heating rod 31 heats the water in the support tube 32 to enable carbon dioxide in the water to escape and permeate out from the water permeable holes 33 formed in the surface of the support tube 32. Also disposed within the support tube 32 are a pH detector, a temperature probe, a TDS probe, and a temperature controller.
The support tube 32 is covered with a gas permeable tube 34, and the gas permeable tube 34 is made of gas permeable and waterproof material, such as expanded polytetrafluoroethylene material. In the heating and degassing process, carbon dioxide gas passes through the expanded polytetrafluoroethylene material to escape to the outer layer, the first air pump 35 is communicated with the air permeability pipe 34, the first air pump 35 is used for forming a high-speed air flow layer 36, and the carbon dioxide gas escaping from the high-speed air flow layer 36 capture is carried into the air to be released, so that the carbon dioxide degassing is realized, the concentration of calcium ions in water is reduced, the calcium carbonate particles are increased, and the SIc index is increased.
Referring to fig. 10 and 11, increasing the temperature increases the water SIc index, decreases the calcium ion concentration, and increases the calcium carbonate particles in the water. When the temperature is higher than 30 ℃, the carbon dioxide in the water body is basically completely deaerated, and SIc reaches the maximum value and is basically stable. Considering that the water temperature of the calcareous landscape area at the east edge of the Qinghai-Tibet plateau is generally not more than 20 ℃, the upper limit of the temperature strengthening unit is set to 20 ℃, and the typical temperature is 10-15 ℃.
Referring to fig. 12 and 13, increasing the temperature increases the content, size and promotes the formation of good morphology of the nascent calcium carbonate particles in the body of water. The particle size of calcium carbonate particles in water with lower concentration can reach the maximum value rapidly at low temperature (10-30 ℃), the content is continuously increased, the particle size of water with high calcium concentration (such as source spring water) is still increased at the temperature exceeding 50 ℃, and the particle size reaches the maximum at low temperature (10-30 ℃).
As the temperature increases (0-50 ℃), the average particle size of the particles in the water of the colorful tank (G1) is in an ascending trend, and the maximum particle size reaches 2.87 mu m at 50 ℃. The average particle size of the particles in the ditch water (G2) is increased firstly and then decreased, and reaches the maximum 3.28 mu m at the temperature of 10 ℃. The average particle size of the particles in the water of the Yingyue color pond (G3) is increased firstly and then decreased, and reaches the maximum of 3.26 mu m at the temperature of 10 ℃.
Along with the temperature rise (0-50 ℃), the surface density of particles in the water of the colorful tank (G1) is in a law of falling after rising, and reaches the maximum of 4079 particles/mm 2 at 10 ℃. The surface density of the particles in the ditch water (G2) is in a law of descending after rising, and the maximum density of 952 particles/mm 2 is reached at 30 ℃.
