And completing one circulation and entering the next water treatment circulation.

The specific control mode and the time sequence are the prior art.

The working principle of the water treatment system is as follows:

the water treatment devices are connected in series, namely cascaded, and the 'purified water' formed by filtering the previous water treatment device enters the next stage for continuous treatment, so that impurities in the water are filtered more, and the water quality meets the relevant national standards better.

The water treatment method comprises the following steps:

a water treatment method, set up the filter element in the container, the filter element is driven by the lifting gearing; the method comprises the following steps:

step 1: liquid feeding and dosing;

the controller starts the electric control lifting driving mechanism to lift the filter element, controls the water inlet valve and starts the dosing mechanism to enable water to be treated and a medicament to enter the container, and the water to be treated is ejected from the water inlet pipe to wash the outer wall of the filter element, so that the self-cleaning of the filter element is realized;

stopping rotation of the filter element after the filter element rises to a preset position (such as an upper limit position);

the discharge pipe is closed in the liquid feeding process, so that the liquid in the container is prevented from flowing out;

for adding chemicals, a purifying chemical (such as a flocculating agent, preferably, a chemical and water are simultaneously added into a container) is added at the same time of water inlet, or the purifying chemical is added after the water is added into the container; or adding the chemicals first and then feeding water; as long as the medicine and the water can be fully mixed and reacted;

the dosing mechanism is arranged in the container and is used for feeding the water treatment medicament into the container;

the drug is administered by the administration means, and the drug is administered simultaneously when water is added, and the drug is preferably added through a separate tube, and preferably a solution with the drug is administered. Controlling the liquid medicine to enter or stop entering through a valve; or directly into a solid or powder medicament, not shown.

Step 2: a reaction step;

stopping feeding liquid after the liquid in the container reaches a certain set liquid level, and waiting for a preset time to enable the medicament in the solution to fully act;

and step 3: pumping water;

the controller drives the filter element to descend through the electric control lifting driving mechanism, the filter element descends to a preset height to ensure that the lower end of the water outlet pipe contacts the liquid level, the water suction pump is started, and the water which is treated in the filter element is sucked through the water suction pipe;

and 4, step 4: a step of discharging waste materials;

after the water in the filter element is pumped, the controller opens a discharge valve on a discharge pipe, so that the sediment at the bottom in the container is discharged (or sucked out); [ regarding the discharged fertilizer, the waste can be further dehydrated, such as by using a stack screw machine, a plate filter and other equipment ]

After the sediment is discharged, the discharge pipe is closed again;

and (5) ending the step, or returning to the step 1 and starting the water treatment process of the next period.

Water inlet pipe for water treatment device

As shown in fig. 17 to 19, the body 51 of the water inlet pipe used for the water inlet pipe in the water treatment device is in a surrounding shape as a whole; the outer end 54 of the water inlet pipe body is plugged; a plurality of water outlet holes 52 are arranged on the water inlet pipe; the water treatment device is provided with an inner barrel and an outer barrel.

The apopore is located the inboard of outer winding form body, and the direction of the water of being convenient for to jet out from the downthehole is to the central direction (for example radial and directional centre of a circle) to certain angle (for example 15 degrees) of cheap, can wash the interior bucket by the way when intaking like this.

The pipe body is annular on the whole, and the inner ring diameter of the pipe body is larger than the outer diameter of the inner barrel.

The pipe body is fixed on the inner wall of the opening of the outer barrel by welding or by a plurality of hooks.

The whole body of the pipe body is in a regular quadrangle, as shown in figure 7, so that the pipe body can be matched with a square filter element; furthermore, the filter element can be deformed in a positive n shape, wherein n is more than or equal to 5 and is matched with the shape of the filter element, so that the function of cleaning the outer wall of the filter element can be better played.
