用化学法去除污水中的磷

湖泊磷的富营养化近些年来已越来越多地引起了人们的重视，为了有效控制和去除湖泊内部富集的磷，可以将钙试剂投加入湖水中使之发生化学沉淀反应，生成磷酸盐沉淀来降低磷的浓度，降低水污染．该法适用于处理水量不大，对设备要求不高的情况．本文就探讨了利用这种化学方法处理了污水中磷的过程，实验结果满足去除湖泊水中磷的要求，达到了预期目标，为治理吉林省长春市南湖水的磷污染寻找了技术出路．

Remove the Phosphorus in the Sewerage by Chemical Method

Lake eutrophication has increasingly caught peoples' eyes. In order to control and remove the phosphorus in the lake and depress the water pollution, calcium can be plunged into the lake, then calcium will react with phosphorus in the sewerage and create calcium phosphate. This method adapt to the condition of removing large-sale eutrophical lake and it has not strict require to the equipment. This article discussed the process of dealing sewage by the method, experiment's result meets the require of removing the phosphorus in the lake, reaches the anticipative aim, provides the technically outlet for Nan Lake in the Changchun city.
