Description
Technical field
The present invention relates to low phosphorus water plants breeding method in a kind of enrichment micropollutant water, belong to sewage treatment area.
Background technology
In water body, the main source of phosphorus has chemical fertilizer, human and animal excreta, water and soil loss and phosphorus-containing detergent.In city domestic sewage, the phosphorus in phosphorus-containing detergent is the main source of phosphorus in water body.There are some researches show, the phosphorus in lake, reservoir 80% comes from sewage discharge, and the main source of phosphorus is the use of home washings agent, and the pollution intensity of its phosphorus accounts for 50% left and right of total phosphorus pollutional load.Since entering the sixties, along with world population, intensive Big Lakes district is subject to the organic pollution such as nitrogen, phosphorus, has caused many developed countries and regional concern, has started thus worldwide taboo, the motion of limit phosphorus.For a long period, China mainly solves the emission problem of industrial wastewater, and sanitary sewage does not almost carry out any processing and is just directly disposed in water body.The nitrogen and phosphorus pollution problem of drinking water source receives people's concern gradually, the excessive enclosed type body eutrophications such as lake that cause of nitrogen phosphorus, and water quality deterioration can increase the difficulty to water treatment, is difficult to reach sanitary standard for drinking water by conventional treatment.There are some researches show, in water supply network, the N of 0.25mg/L is just enough to make nitrifying bacteria growth and breeding, and nitrifying bacteria can discharge smelly hiding in metabolic process; Excessive nitrate nitrogen can be reduced to nitrous acid nitrogen in people's stomach, forms carcinogenicity material nitrosamine with secondary amine or the effect of phthalein amine in stomach.In effective removal micro polluted source, NITROGEN IN LOW CONCENTRATION phosphorus has become the hot issue of water treatment field.
Make a general survey of dephosphorization technique both domestic and external, chemical precipitation method and coagulation and filtration method, because its operating cost is high, and produce and in a large number easily cause the chemical sludge of secondary pollution and replace biological phosphate-eliminating technology.In traditional removal sewage, the method for nitrogen phosphorus is to utilize nitrogen, phosphorus in algae purification sewage.Utilize the research of nitrogen, phosphorus in algae purification sewage to start early.As spirulina can be in the eutrophic sewage of saliferous well-grown, under illumination condition, just can absorb most of pollutant through gentle agitation.Can provide a kind of comparatively economic method for treating water with algae, weak point is that unicellular alga volume is small, is unfavorable for collecting, and is therefore not suitable for being used as purifying plant in the great water body such as lake, reservoir.
Summary of the invention
The present invention is directed to the chemical sludge that traditional sewage dephosphorization technology easily causes secondary pollution, the problem that dephosphorization algae can not purify in great water body, a kind of method of utilizing water plants to process phosphor in sewage has been proposed, with the method place phosphorus-containing wastewater, not only nitrogen phosphorus is had to good removal ability, and can be rapidly other lot of trace heavy metals in enrichment waste water in large quantities.
For achieving the above object, the concrete technical scheme that the present invention takes is:
(1) in free of contamination pond, cultivate a collection of water lettuce, remove the leaf of outside until remaining 3～4, sterilization, is moved in the glass jar that 5L fills deionized water, and room temperature, with the illumination of 40w fluorescent lamp;
(2) first, in the deionized water of glass jar, add 0.1g～0.4g sodium dihydrogen phosphate, 2～3g agar, 2～3g glucose sugar, 2～3g sodium chloride and 2～3g magnesium sulfate;
(3) in the time that water lettuce newly grows 2 leaves, pull out its new linear leaf, move in the glass jar that another 5L fills deionized water, room temperature, with the illumination of 40w fluorescent lamp;
(4) illumination, after 6 hours, is moved in previous glass jar, adds respectively 0.4g～0.8g sodium dihydrogen phosphate, 2～3g agar, 2～3g glucose sugar, 2～3g sodium chloride and 2～3g magnesium sulfate;
(5) in the time that water lettuce newly grows 3 leaves, pull out its new linear leaf, move in the glass jar that another 5L fills deionized water, room temperature, with the illumination of 40w fluorescent lamp;
(6) illumination, after 12 hours, is moved in previous glass jar, adds respectively 0.8g～1.2g sodium dihydrogen phosphate, 2～3g agar, 2～3g glucose sugar, 2～3g sodium chloride and 2～3g magnesium sulfate;
(7) in the time that water lettuce newly grows 4 leaves, pull out its new linear leaf, move in the glass jar that another 5L fills deionized water, room temperature, with the illumination of 40w fluorescent lamp;
(8) illumination, after 18 hours, is moved in previous glass jar, adds respectively 1.2g～1.6g sodium dihydrogen phosphate, 2～3g agar, 2～3g glucose sugar, 2～3g sodium chloride and 2～3g magnesium sulfate;
(9) in the time that water lettuce newly grows 5 leaves, pull out its new linear leaf, move in the glass jar that another 5L fills deionized water, room temperature, with the illumination of 40w fluorescent lamp;
(10) illumination, after 24 hours, is moved in previous glass jar, adds respectively 1.6g～2.0g sodium dihydrogen phosphate, 2～3g agar, 2～3g glucose sugar, 2～3g sodium chloride and 2～3g magnesium sulfate;
(11) cultivate after 30 days, water lettuce reaches 111000～185500 to the enrichment enrichment factor of phosphorus.
The significant advantage that the present invention has is:
(1) utilize weter hyacinth to process phosphorus-containing wastewater, its processing method is simpler than additive method.
(2) little energy of processing water consumption;
(3) can effectively utilize plant resources.
