Background technology
At present, along with the fast development of human society, a large amount of undressed sanitary sewages, trade effluent and rural sewage
Substantial amounts of entrance water body, has increased the weight of the load of environment.A large amount of uses of such as people's Powdered Detergent Containing Phosphate, phosphorus-containing detergent, thus
The waste water produced is directly discharged into sewage conduct.Biochemical pharmacy, Treatment of Metal Surface, factory and animal husbandry waste water, mountain forest are ploughed fertile
The processes such as stream mistake and rainfall snowfall also bring along phosphorus-containing wastewater.Environment can be produced a very large impact by these phosphorus-containing wastewaters.Contain
Phosphorus waste water can cause body eutrophication, and body eutrophication not only results in algae overgrowing in water, and water body can be made oxygen-containing
Amount drastically declines, and then causes freshwater fish and other marine products class animal deads；Substantial amounts of phosphorus-containing wastewater enters rivers and also can draw
Play wawter bloom, red tide etc.；Wawter bloom, red tide etc. all can make the transparency of water decline, and again result in the reduction of dissolved oxygen in water, sea water
Color and luster is abnormal, marine ecology is seriously damaged.
In prior art, the processing method for phosphorus-containing wastewater mainly has following several, such as chemical precipitation method, chemical flocculation
Method, absorption method, bioanalysis, crystallization process etc..The gold that the principle of chemical precipitation method produces mainly by iron salt, aluminium salt, calcium salt etc.
Belonging to ion and generate difficultly-soluble phosphates precipitation with phosphate radical, conventional salt has aluminum sulfate, ferrous sulfate and Calx etc..Chemical precipitation
Method phosphor-removing effect is good, simple to operate, non-secondary pollution, meets clean energy resource and produces and the requirement of recycling economy, but but exists
The problem that waste residue amount is big, reagent cost is high.Absorption method dephosphorization is mainly by hypersober, coal dust, slag, kieselguhr, boiling
Phosphoric acid in the absorption waste water such as stone, absorption method application is the most universal.But, when using existing adsorbent easily by sewage other
Material is corroded and is destroyed structure, causes hole to cave in destroyed, affects adsorption effect.
Summary of the invention
For treatment of Phosphorus Containing Waste Water material above shortcomings in prior art, the invention provides a kind of phosphorus waste water
