2. bed mud dredging: the bed mud dredging can migrate out water ecosystem with the pollutent in the bed mud, especially can significantly reduce water body endogenous phosphorus load.But, be not effectively certain, particularly all the more so under the situation that source of pollution are not effectively controlled outside for the water body of control water pollution, especially eutrophication.
3. diversion dirt removal and change water dilution: diversion dirt removal and change water and dilute and a large amount of pollutent can be transported to the downstream within a short period of time, reduce the concentration of local water pollutant, but this method can only make pollutent shift but not degraded, and can the downstream in basin be polluted.
2) chemical method comprises:
1. traditional chemical algae removing: traditional chemical algae removing is simple to operate, can obtain at short notice and significantly remove the algae effect, improves water transparency.But nutritive substances such as nitrogen, phosphorus can not be cleared out of water body, and the algicide of life-time service lower concentration can make also algae develop immunity to drugs.
2. flocculation sediment: the flocculation sediment technology discharges for the phosphorus of control endogenous phosphorus load, particularly bed mud, and certain effect is arranged.But sedimentary mud meeting association secondary pollution, collaborative usually other technology is as the pre-treatment measure.
3. the chemical fixation of heavy metal
This method can be combined in heavy metal in the bed mud, suppresses the release of heavy metal.Heightening pH value is that heavy metal is combined in main chemical process in the bed mud, will add alkaline matters such as lime, lime carbonate slag, slag usually, but amount of application should be not too many, otherwise can exerts an adverse impact to aquatic ecosystem.
3) the biological-ecological method comprises:
1. microbially decontaminate technology: the microbially decontaminate technology have cost saving, effective, disturb fewly to external world, do not have or plurality of advantages such as secondary pollution seldom, become the focus of research day by day, and obtained certain regulation effect.But no matter be single culture or composite bacteria, all have the environmental compatibility problem.Simultaneously, inoculating microbe especially " engineering bacteria " the biological safety problem of environment also is subjected to the extensive worry of various circles of society.
2. aquatic plant purification technology: utilize aquatic plant purification sewage, it is low to have a cost, and energy consumption is little, and to advantages such as environmental perturbation are little, and waterplant has the ability of extremely strong enriching heavy metal.But aquatic plants growth is crossed secret meeting and is caused that the mosquito evil is living, and the plant residue salvaging is untimely to cause secondary pollution, and the growth of plant is subject to the influence in season.
3. artificial swamp technology: the removing pollutant process of artificial swamp relates to physics, chemistry, biological many-sided comprehensive action, can be used for reducing point source and pollution of area source loads such as agricultural, highway, cities and towns, but floor space is big, the design and operation parameter fuzzy, biology and water conservancy complicated condition are subject to the disease and pest influence.
4. stabilization pond technology: stabilization pond have simple structure, capital construction working cost low, remove the efficient advantages of higher, but have problems such as floor space is big, the bed mud alluvial is serious.At these problems, the better deformation techniques of treatment effect such as the higher synthesis stabilization pond and the comprehensive organism pool on the basis of traditional stabilization pond, have been developed both at home and abroad.
