摘要
试验了氢氧化钙、硫酸铝、硝酸钙、硫酸亚铁对抑制湖泊沉积物向水体释放磷的有效性,药剂投加量分别为1∶1、1∶2和过量,试验历时24 d,4种药剂对水体磷去除率最高分别可达到86.2%、91.7%、90.3%和93.1%,但处理效果随时间会发生变化。
Calcium hydroxide,aluminium sulphate,calcium nitrate and ferrous sulphate have been applied to treating wastewater of phosphorus for 24 days in manner of 1 : 1,1 : 2 and excessive. The results show that max reduction ratios of phosphorus are 86.2 %, 91.7 %, 90.3 % and 93.1%, respectively, but the effect of treatment fluctuates in the test period.
