Problems solved by technology

[0002] The formulas for aquaculture wastewater treatment mainly include physical treatment, chemical treatment, physicochemical treatment and biological treatment. Among them, the first three treatment methods require a large amount of equipment investment and high cost, and chemical treatment usually requires the addition of chemical agents. It may cause secondary pollution of water body; biological treatment method is a common treatment method for aquaculture wastewater at present, which has the advantages of low cost and mild treatment method; It plays an important role in the process, but different algae have different requirements for the growth environment, and they have different treatment capabilities for different sewage or different pollutants in the same sewage.

Embodiment 1

[0022] According to the amount of aquaculture wastewater, the quality of the bacteria solution of Chlorella pyrenoidosa, Sclerophylla oblique and Crescent algae required in each cubic meter of aquaculture wastewater is 0.5g, 1.5g, and 1.5g respectively to determine the amount of three kinds of algae solutions required. Quantity: Centrifuge the above-mentioned Chlorella pyrenoidosa liquid, Sclerophylla obliquus liquid and Crescent algae liquid at 6000 rpm for 15-35 minutes, discard the supernatant, wash with 25 mg / ml sodium bicarbonate solution, and repeat three times ; The obtained chlorella pyrenoidosa liquid, oblique algae liquid and crescent algae liquid are respectively added in the culture waste water of 1 cubic meter according to the volume ratio of 1:5:5, and at 25° C., the strength is 5000lx The white fluorescent lamp was cultivated for 5 days with a light ratio of 12:12 hours, and it was shaken manually every 3.5 hours; then, an equal volume (0.5m 3 ) of the chlorella...

Abstract

The invention discloses a formula for treating waste water for aquaculture. According to the treatment method, chlorella pyrenoidosa, scenedesmus obliquus and selenastrum capricornutum are adopted for interaction treatment and culture, and experimental research is done on the waste water. The formula for treating waste water for aquaculture is capable of effectively eliminating substances such as nitrogen and phosphorus existing in the waste water in different forms, and has the advantages of being simple, effective, low in cost, high in practicality and the like; moreover, algae grows and can serve as food of aquatic animals, cost is low, the effect is remarkable, and the living environment of the animals and plants is not influenced.

Description

technical field [0001] The invention relates to the technical field of aquaculture wastewater treatment, in particular to a formula for treating aquaculture wastewater with low cost and good effect. Background technique [0002] The formulas for aquaculture wastewater treatment mainly include physical treatment, chemical treatment, physicochemical treatment and biological treatment. Among them, the first three treatment methods require a large amount of equipment investment and high cost, and chemical treatment usually requires the addition of chemical agents. It may cause secondary pollution of water body; biological treatment method is a common treatment method for aquaculture wastewater at present, which has the advantages of low cost and mild treatment method; It plays an important role in the process, but different algae have different requirements for the growth environment, and they have different treatment capabilities for different sewage or different pollutants in ...
