Description
Technical field
The present invention relates to water treatment field；
The dystopy being specifically related to a kind of river channel type water head site water body purifies and water quality maintenance system.
Background technology
In recent years, since, the city of China plains region achieves the achievement of economic rapid growth, but has also paid environmental pollution and life
The cost that state is destroyed, increasing city is faced with water pollution problems, and in river water body, the polluter such as Organic substance, nitrogen phosphorus contains
Amount raises, it is impossible to meet the requirement as potable water source district.Additionally, many water supplying rivers also have the multiple society such as shipping, irrigation concurrently
Meeting function, this makes open river channel type water head site also be exposed under the risk of chemical spill and pollution by pesticides.In order to purify water
Matter, avoid risk, in Jiangsu, Zhejiang, the plains region such as Shanghai, river channel type water head site water body is carried out dystopy purification and arranges
Storage reservoir has become the main trend served a town with water.
Raw water of micropolluted water carries out under the conditions of in the wild large-scale dystopy process and water-retention, with sewage disposal or tap water
The indoor process technique of factory is different, and its ultimate challenge faced is exactly the lance between project occupation of land demand and urban land anxiety
Contradiction between shield, water water quality complicated and changeable and stable water outlet are up to standard.The water body dystopy purification that domestic and international application is relatively broad
Technique may be summarized to be physics, chemistry, biology and the big class of ecological technique 4, and various methods all have a lot of application cases, but
Clean-up effect, cost of investment and occupation of land demand side have bigger difference.With physics with chemical method (as resin absorption, film divide
From, chemical oxidation etc.) although take as the leading factor technique instant effect, high treating effect, but changed by raw water quality and affected the most greatly,
Operation maintenance achievement is too high, does not meets the theory of low-carbon environment-friendly；And with biological and ecological method (such as biofilter, artificial swamp etc.)
The technique taken as the leading factor has the advantages that landscape effect is good, operating cost is low, buffer capacity is strong, but it is excessive to there is floor space, easily
The problems such as effect fluctuation are caused by the change of seasonal climate.
Summary of the invention
The technical problem to be solved is aiming at above-mentioned deficiency present in prior art, it is provided that a kind of river channel type water source
