Description
Technical field
The present invention relates to a kind of method for purifying water of source-free water area, particularly for the method and the facility thereof of the water conditioning of the large-scale source-free water area in the city.
Background technology
Along with economy and fast development of urbanization, the problem of water pollution and shortage of water resources is serious day by day, what wherein problem was the most serious is those large-scale source-free water areas, promptly there are not lake that the fixed river imports, reservoir etc., because can not get the fixed water source for a long time replenishes, the flowability difference of water is evaporation concentration simultaneously, add the body eutrophication that causes by the nitrogen phosphorus substance in the water, thereby cause the algae transition breeding in the water to be the wawter bloom phenomenon, reduce the transparency of water, cause the dissolved oxygen in the water to reduce, make water have peculiar smell; Some algae produces toxin harm hydrobiont in addition, influences human health, has destroyed aquatic ecological.
And be arranged in the source-free water area in city for those, be mostly collect amusement and recreation in the city, recreation and sports are the modernized park of one, broad masses of the people's physical and mental health has been play a part useful, so the purification of its water quality is even more important.Yet existing improvement method is fairly simple, mainly adopts dosing mode to carry out the stage and administers, because lake water is mobile relatively poor, treatment effect is not obvious, and the medicine that adds simultaneously causes detrimentally affect again to water quality.
At present water scarcity or exhausted phenomenon all appear replenishing in landscape water bodies such as each park, incity, big city and lake, river, and for protecting existing river Lake Water Body, major part has adopted in the regeneration that water is as the moisturizing water source, and some has obtained certain economic benefits and social benefit.In addition, because water resources lacks, be the conserve water resource, in existing a lot of urban green spaces, construction of park and the large-scale landmark building, artificial lake, sloot and landscape pond adopt that water carries out moisturizing in the regeneration, irrigate, flush the toilet etc.
Though water has solved the moisturizing problem of view in the regeneration, but it is little owing to amount of makeup water, the water body fluidity is poor, the water quality evaporating-osmosis concentrates and to make in the water multiple reason such as nutritive substance concentration rising, cause water body to worsen, the wawter bloom phenomenon occurs, influence the view functions of use of water body.So, aspect treating landscape water body, rationally solve the make up water source problem, also should increase the detergent power of water body.Therefore, method and the facility that a kind of water body treating of comparatively perfect source-free water area and keeping purifies need to be proposed.
