Description
Technical field
The present invention relates to a kind of sewage purification system, be specifically related to a kind for the treatment of of Phosphorus Containing Waste Water purification system.
Background technology
Phosphor in sewage element exceeds standard, and can accelerate the eutrophication of water body, and this phenomenon is comparatively serious in China, all brings great harm to industry, water industry, agricultural and tourism.The nutrient concentrations such as nitrogen, phosphorus raises, and being the reason of algal bloom, is again wherein key factor with phosphorus.Therefore, how effectively to reduce the concentration of phosphor in sewage, to decontamination, protection of the environment, tool is of great significance.Therefore, country has made strict regulation to the content of total phosphorus in the sewage of discharge after process, mostly all requires that the content of total phosphorus in sewage can not more than 0.5mg/l.
At present, domestic and international sewage dephosphorization technology mainly contains biological process, the large class of chemical method two.Biological process is as A/O, A
2/ O, UCT technique, main being applicable to, processes lower concentration and organic phosphorus-containing wastewater; Chemical method and physico-chemical processes mainly contain the techniques such as coagulant sedimentation, ion exchange adsorption, electrodialysis, reverse osmosis, and main being applicable to processes inorganic states phosphorus-containing wastewater.
Biological process is generally only applicable to the phosphorus-containing wastewater of lower concentration, and as required, total phosphorous is less than below 10mg/l.Its cutting mechanisms is polyP bacteria excessive adsorption, is then reached the object of dephosphorization by mud discharging.Owing to easily discharging after polyP bacteria excessive adsorption, sludge dewatering also can make total phosphorus again enter water body, thus causes the pollution again of total phosphorus, and the method treatment effect is unstable again.
And conventional coagulant sedimentation is not very good to the removal effect of high-concentration phosphorus-containing wastewater yet, after general process, total phosphorus is also at about 1mg/l, reduces often effect further unstable.And the technology investments such as ion exchange adsorption, electrodialysis, reverse osmosis are high, operational management requires high, if the bad processing power causing fouling membrane generally not easily to recover film of pre-treatment, loss is very large, therefore generally seldom adopts.
In various phosphorus-containing wastewater, be maximum with the phosphorized waste water intractability produced in metal phosphorizing process, because its phosphoric acid salt quantity discharged is large, and contain the inorganic salts such as the zine ion of higher concentration, also have the pollutent such as petroleum-type and suspended substance in addition.According to feature and the phosphatization drainage situation of phosphorized waste water, the emphasis determining such wastewater treatment removes PO
4 3-, petroleum-type and Zn
2+deng.At present, when using coagulant sedimentation Removal of Phosphorus in Wastewater, after waste water is mixed with precipitation agent and flocculation agent in reaction tank, Direct precipitation is separated, and effect is bad.
