Embodiment 1

[0027] According to the amount of aquaculture waste water, the bacterial liquid quality of Chlorella pyrenoidosa, oblique algae and crescent algae required in each cubic meter of aquaculture waste water is 0.25g, 1.25g, 1.25g to determine the required three kinds of algae liquid. Quantity: Centrifuge the above-mentioned Chlorella pyrenoidosa liquid, Alpine algae liquid and Crescent algae liquid at 5000 rpm for 10-30 minutes, discard the supernatant, wash with 30 mg / ml sodium bicarbonate solution, and repeat three times ; The obtained chlorella pyrenoidosa liquid, oblique algae liquid and crescent algae liquid are added respectively in the culture waste water of 1 cubic meter according to the ratio of 1: 5: 5 according to the volume ratio, at 25 ℃, use intensity as 4000lx The white fluorescent lamp was cultivated for 4 days with a light ratio of 12:12 hours, and it was shaken manually every 4 hours; then, an equal volume (0.5 m 3 ), the chlorella pyrenoidosa liquid, the oblique...

Abstract

The invention discloses a treatment method of aquacultural waste water. According to the treatment method, three kinds of algae, including chlorella pyrenoidosa, scenedesmus obliquus, and pseudokirchneriella subcapitata, are used for treating aquacultural waste water. According to the treatment method, a mixture of the three kings of algae is capable of removing substances in different forms, such as nitrogen and phosphor, in waste water; the treatment method is simple and effective, is low in cost, and is high in practicality; and the algae can be taken as food of aquatic animals.

Description

technical field [0001] The invention relates to the technical field of aquaculture wastewater treatment, in particular to a treatment method for aquaculture wastewater. Background technique [0002] The aquaculture industry is the largest in all animal food supply chains. However, with the rapid development of my country's aquaculture industry, it has brought huge economic benefits. At the same time, the aquaculture water has also been seriously polluted, with a large amount of pollutants such as nitrogen and phosphorus. It exists in the wastewater discharged from aquaculture, and eutrophication occurs. If it is allowed to develop, the development of aquaculture will be restricted to a large extent due to water quality problems. [0003] The treatment methods of aquaculture wastewater mainly include physical treatment, chemical treatment, physicochemical treatment and biological treatment. Among them, the first three treatment methods require a large amount of equipment inv...
