Description

The method that aquatic vegetable and Cyprinus carpio are cultivated using lake inlet Ecology
Technical field
The present invention relates to the sewage treatment area being characterized with ecologic breeding, more particularly to a kind of aquatic using lake inlet The method that state cultivates aquatic vegetable and Cyprinus carpio.
Background technology
In the last thirty years, many lake runoff area agricultural productions are with the adjustment of crop mix, Crop Structure and layout Very big change is given birth to, cereal crops sown area is reduced, and vegetable area increases rapidly, and strong promotes region rural economy Fast development.Vegetable for cereal crops is a kind of larger crop of fertilizer requirement, and multiple crop index is high, so leads Cause the fertilizer amount that land area of one unit was applied within the unit interval greatly increase, add the unreasonable fertilising of peasant household, cause soil Earth nutrient structure is uneven, and remaining nutrient increases, and easily moves with water and flows into river(Ditch)In.Lake runoff area has trunk river many Bar, flows into the nutrient in trunk river except having outside the Pass with agricultural fertilizer, also multi-party by aquaculture, human lives' rubbish and plant residue etc. The impact in face, so with the arrival in rainy season(Rain drop erosion)And the discharge of irrigation water, river certainly will be caused(Ditch)Nutrient in water Content increases, and Water seeks its own level, river(Ditch)Water is flowed in lake, causes water pollution to lake water(Mainly the rich of N, P nutrient is sought Fosterization pollutes).
Body eutrophication (eutrophication) refers to that under the influence of mankind's activity the nutrient substance such as nitrogen, phosphorus is big Amount causes algae and other planktons to breed rapidly, under Dissolved Oxygen in Water amount into slow flow water bodies such as lake, river mouth, bays The phenomenon of drop, water quality deterioration, Fish and other biological mortality.This phenomenon goes out now known as wawter bloom in rivers and lakes, Go out now known as red tide in ocean.
Mainly there are at present Physical, chemical method and bioanalysises to polluted-water comprehensive control, or three major types method It is comprehensive to use.In its bioanalysis(1)Using Antimicrobial wawter bloom,(2)Using animal ingestion wawter bloom algae,(3)Transplanting is aquatic Plant controls wawter bloom algae, and it is exactly using the principle counteracted each other between each biology, by changing to control blue-green alga bloom with water plant The intensity and nutritional condition that become ambient light affect indirectly the breeding of wawter bloom algae, improve water transparency, plant and root area Microbe symbiotic, produces cooperative effect, purifies water, then directly absorb through plant, microorganism conversion, physical absorption and sedimentation Effect reaches control or kills the purpose of some algae except denitrification, phosphorus and particle.Bioanalysises have higher selection except algae Property, the life of non-wawter bloom bio will not be affected, and method is simple, be suitable for the water of culture zone, the multiple area of wawter bloom and district occurred frequently China's preventing and treating, is a kind of extremely promising prevention and controls.Further process Organic substance, nitrogen and phosphorus of difficult degradation etc. and can result in water body Soluble inorganic matter of eutrophication etc..Main method has biological carbon and phosphorous removal method, and coagulant sedimentation, sand filtration method, activated carbon are inhaled Attached method, ion exchange and electroosmose process etc..
Transplanting water plant control wawter bloom algae during at present body eutrophication is administered is mainly Herba Eichhorniae and aquatic Plant, but Herba Eichhorniae, because of its excessively fast passage, wayward, value is lowly and substantially without economic benefit.Other administering methods Though the benefit of certain ecology can be obtained, input is big, substantially without economic benefit.
