It is black smelly, the water body deterioration problem such as the eutrophication in lake, reservoir and immediate offshore area, China's input substantial contribution
The pollution problem in the river of improvement, lake and reservoir, the basic reason for causing these water bodys to deteriorate is organic dirt
It is relatively low etc. to contaminate (COD), nitrogen and phosphorus pollution, dissolved oxygen.
At present, traditional phosphorus removing method mainly has three kinds, first, chemical precipitation method：Coagulant is launched to water body,
Generate Ca5OH(PO3)3、AlPO4、FePO4Deng the sediment of slightly solubility, this chemical precipitation method needs to throw
The coagulant of amplification quantity, not only cost is high, and can also form sludge causes secondary pollution of water；Second, bioanalysis：
Plantation has the water plant of purification and absorption property to nitrogen phosphorus in water, and nitrogen and phosphorus are stored into plant tissue
In after drag for away, but limited by season, environmental condition larger；Third, absorption method：Physical absorption and chemisorbed,
It is phosphorus removing method the most frequently used at present, but absorption method dephosphorization efficiency is not high, after launching a large amount of adsorbent powders,
Mud can be caused to increase, recovery is difficult, causes secondary pollution of water.
