Aquaculture becomes more and more important in people's lives.Pond culture occupies very important ground in the fishery in China
Position, to obtain higher economic interests, in recent years, culturist mostly uses high density to put in a suitable place to breed, the aquaculture model of heavy dressing bait throwing in.
The nitrite generated in breeding water body is the intermediate product that ammonia is converted into nitrate, since culture pond residual bait, excrement were accumulated
It is more, generate ammonia nitrogen constantly, in addition the born inertia of nitrobacteria group and to the fastidious of metabolic conditions, so when temperature relatively
Low, algae is mutually uneven or when for hypoxgia, and nitrobacteria group, which is metabolized nitrite that is slow and leading to breeding water body, to be accumulated and increase；
Water body inorganic nutrient salt is too low, organic nutrition is superfluous, the precursor flora of decomposition nutrition is reduced, high temperature and rainy is all to cause algae
Factor and the high risk link of aquaculture, a large amount of algae toxin are also ceaselessly being alternately produced, and lead to aquaculture organism liver pancreas
The diseases such as popular name for change, jejunum sky stomach, enteritis occur, and inorganic nutrient salt (such as calcium, phosphorus, magnesium) need to be replenished in time；Since water body is residual
The organic matters such as bait, excrement are excessive or algae causes water surface a large amount of foams or tan solid savings occur, cause water quality
Smelly, anoxic.
With the fast development of such intensive aquaculture industry, breeding wastewater is increasingly tight to the pollution problem of environment
Weight, water quality deterioration, pollution are on the rise.The deterioration of water environment brings massive losses to booming culture fishery, becomes
The significant problem that international community and food safety face, cultivation water pollution, which has become, restricts aquaculture sustainable development
Urgent problem to be solved.
