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
The present invention relates to aquiculture waste water processing technology field, particularly relate to a kind for the treatment of process of aquiculture waste water.
Background technology
Culture fishery is largest in all animal food supply chains, but the develop rapidly along with China's culture fishery, when bringing great economic benefit, aquaculture water has also suffered severe contamination, nitrogen, the pollutents such as phosphorus are present in the waste water of aquaculture discharge in a large number, occur eutrophication.Its development if leave, the development meeting of culture fishery is subject to restriction to a great extent because of quality problem.
The treatment process of aquiculture waste water mainly contains physical treatment process, method of chemical treatment, physicochemical treatment method and biological treatment.Wherein, first three equipment investment amount of planting treatment process is large, expense is high, and chemical treatment method need to add chemicals conventionally, may bring the secondary pollution of water body; Bioremediation is the conventional treatment process of current aquiculture waste water, has the advantages such as cost is low, treatment process is gentle.Algae, as the important primary producer of aquatic ecosystem, is purifying water, and in water surrounding repair process, plays an important role.But different algal species has different requirements for growing environment, different for different Pollutant Treatment abilities in different sewage or identical sewage, this just causes and utilizes merely a kind of algae to process the sewage DeGrain producing in aquaculture process.
