Description
Technical field
The invention belongs to farm field irrigation drainage system, controlling area-source pollution, field of water quality purification, and in particular to a kind of ecological purification
Artificial canal island system.
Background technique
The sustainable growth of agricultural output is pushed due to continuing to increase the agricultural input products such as chemical fertilizer, pesticide, results in agriculture
The aggravation of industry pollution of area source and the deterioration of agricultural environment.Grogs, N, P, pesticide, heavy metal, fowl and animal excrement and life rubbish in farmland
Rubbish etc. by agricultural surface runoff, agricultural drain and underground leakage enters water body with rainfall and runoff, causes the deterioration of water quality.
Existing majority result of study shows that the nitrogen and phosphorus loss in agricultural run-off is one of important sources of water eutrophication (BOESCH
D.F.,et al,2000；SHARPLEY A.N.,et al,2003；TABUCHIT.,et al,2005).It reduces in agricultural production
Nitrogen, phosphorus using and discharges, and is to the important means for slowing down water eutrophication, improving water quality.Thus researchers at home and abroad
Controlling area-source pollution means are focused on to the circulation for blocking polluter in the water of farmland, directly during transportation of pollutant
Purification.China renovates the improvement of pollution of area source, farmland, attention each year of construction of water conservancy works all mentions a new height
Degree.Various regions establish a large amount of artificial swamp, rain sewage treatment plant etc., it is also considered that have arrived the benefits such as economy, landscape, ecology.But
It is that these purification systems are too simple, also without utilizing existing some available resources, efficiency of water application is not high.
