Greatly.The demand of grain is big, and the demand of agricultural water also increases therewith.Traditional leaching irrigation technology not only causes the wave of water resource
Take, also easily cause saline Land, and can in large area fine particle or it is water-soluble in pollutant bring to underground
In water body or surface water.Over nearly 30 years, peasant changes made doing for fertilizer fertilising with farm animal excrement in process of production in the past
Method, starts a large amount of useization excrement and agricultural chemicals.Because farm animal excrement volume is big, fertilizer efficiency slow, store transport inconvenience, using trouble,
Therefore, the feces of livestock and poultry for being once once considered as " resource " becomes waste, not only nowhere can use, and as environmentally hazardous dirt
Dye source；Comparatively, the easy storage of chemical fertilizer, Portable belt, cheap, becomes the preferred fertilizer of peasant, and to ensure grain
Yield and quality, peasant can also put into a certain amount of agricultural chemicals in planting process.Chemical fertilizer is soluble in water and is filled with substantial amounts of
When irrigating flowing water input water body, it can bring the problem of body eutrophication caused by nitrogen, phosphorus, potassium excess；Agricultural chemicals enters water body, meeting
Cause the pollutants such as organochlorine, organophosphor, organo-arsenic, these toxic pollutant Stability Analysis of Structures, not degradable, toxic residue time
It is long, there is very big harm to ecological environment, if people have drunk the water by such pollution, be easily caused slow poisoning, also
May disable, teratogenesis, the serious survival and development for threatening the rural area people.
It is existing to be administered for agricultural non-point source pollution draining, mostly using anaerobic pond, facultative lagoon, aerobic ponds, aerated pond etc.
The system of stabilization pond etc, but the impurity in the treated water of current system is relatively more, it is impossible to be used in field irrigation, it is impossible to
Realize recycling for water and cause to waste.
The content of the invention
The purpose of the application is above-mentioned existing for agricultural non-point source pollution draining improvement in order to solve, mostly using anaerobism
