Description
Technical field
The invention belongs to sewage disposal device manufacturing technology field in environmental conservation, it is especially useful in the water pollution in finite width river course processes, be a kind of for processing fixing filler circulation low-purity oxygen plant and the control method that urban river water pollutes.
Background technology
Urban river is a flowing and the Complex Ecological Systems that is closely connected of life of urban resident environment in urban look, and originate as the main water of residents from villages and towns in river, small towns, has highly important status with urban river is the same in people's life.External source pollution is had certain oneself and purifies recovery capability by river, but in recent years, river is large number of due to littoral resident, new plant is assembled in a large number, the productive life of resident and the row of stealing of factory steal river of being rivals in a contest and cause tremendous influence, city and small towns river ecological function is caused constantly to degenerate and losing, occur that black smelly, mosquito grows, not only lose the function as domestic water source and urban look, become city burden on the contrary: not only disturb the normal productive life of resident, resident is healthy harmful, even have impact on city reputation.
Recent years, people constantly explore river channel ecology administering method, and at present, method substantially can classify as Physical, chemical method and bio-ecological process.
Physical includes cutting dirt, desilting, oxygen enrichment and water-filling.Cut the effective approach that dirt is river improvement, but, river interception project is great, involve a wide range of knowledge, including the laying of a large amount of pipe networks, Sewage Plant construction, personnel's moving, river periphery restoration of the ecosystem, factory and enterprise blowdown control etc., its huge construction investment, very long duration and complicated engineering construction, make that numerous river authorities are unable to be undertaken.Desilting, due to long-term natural sediment, has built up a large amount of mud bottom river, removed by bed mud from the body of river, can reduce the nutritive salt being accumulated in sediments, reduces potentiality internal contamination source, is the direct effective measures reducing endogenous pollution.But, after desilting, water quality can only temporarily improve, and along with the input polluted, river quickly deposits again and goes back, and quantities is big, and investment cost is high.Reoxygenation, with serious pollution river water is owing to oxygen consumption is more than the natural reaeration amount of water body, and dissolved oxygen is very low, even in anoxia (or anaerobism) state.Carry out artificial oxygenation to the river course being in anoxia (or anaerobism) state, it is possible to strengthen the self-purification capacity in river, improve water quality, improve or recover the ecological environment in river.Due to the good result of stream aeration reoxygenation engineering and relatively low investment and operating cost expense, become during developed country administers with River water pollution through frequently with method.Water-filling, dilutes polluted water body by engineering means diversion, reduces the pollutional load of water body in the short time, improves the living environment of aquatic animal, water plant, improves the self-purification capacity in river.But change water to rush the total amount of rare after stain and do not reduce, be really pollutant and marry again, if extraneous contamination sustainable existence, quickly can return to original level of pollution, and waste the water resource of high-quality.
Chemical method includes dosing coagulant, algicide.Directly adding " coagulant " instant effect in river, but pharmaceutical quantities is difficult to grasp, accumulation of pollutants destroys benthon environment in river bed, and there is the probability polluting secondary release.And use algicide can remove the nitrogen in algae and water, but the phosphorus in water body cannot be removed；The growth of other biologies such as Fish is endangered very big by the bio-toxicity of chemistry algicide.Chemical method is aiming at the contamination characteristics in river and adds corresponding chemical agent, forces to remove polluter, and water quality of river is obviously improved.The method is simple to operate, but costly, easily causes secondary pollution.
