摘　　要：Phoslock是一种改性土壤产品,它能有效净化水体中的可溶性磷酸盐,从而达到有效控制水体富营养化的目的。开展Phoslock应用于滇池富营养化水体污染净化的现场示范试验,并对其净化效果进行研究。结果表明,Phoslock对滇池水体中可溶性磷酸盐的去除效果好,能有效控制水体富营养化。Phoslock不仅能快速降低水体中可溶性磷酸盐浓度,也能在相对长的一段时期内保持其处于较低水平。经Phoslock处理后的滇池富营养化水体,透明度较高,且水体中可溶性磷酸盐和总磷浓度都处于较低水平,且对生活污水、农业面源污染等外源污染物的抗污染负荷能力较强,可见,Phoslock是一种对自然水体安全、对水生生物无害的新型污水除磷试剂。As a modified product,Phoslock can purify soluble phosphate（SP） in water in order to control water eutrophication effectively.The site demonstration test was used in the purify eutrophic water based on phoslock and the purified effects were studied.The results showed that Phoslock had better removal effect for soluble phosphate in Dianchi Lake water to control water eutrophication effectively.Phoslock not only reduced soluble phosphate concentration in water but also kept it at a lower level for a long time.Eutrophic water in Dianchi Lake treated by Phoslock had higher transparency,and the concentrations of soluble phosphate and total phosphorus（TP） were lower,with stronger anti-pollution ability to domestic sewage and agricultural non-point pollution.Therefore,Phoslock was a new dephosphorization reagent used in sewage,which was safe to natural waters and aquatic organisms.
