It is the rivers and lakes that have bred up people of Wuhan for generations. Unfortunately, urban lakes have fallen into an awkward situation with the rapid development of urbanization and sharp increase of urban population in recently years. The numbers and areas of urban lake have sharply decreased; some urban lakes have deposited; some became swamp. Additionally, soil erosion caused by human factors has shoaled lakes and reduced reservoir capacity. Trade-waste sewage and domestic sewage flow into lakes, which has caused the deterioration of water quality.

然而随着近年来城市开发的力度不断加大，城市人口的快速增长，城市湖泊陷入了十分难堪的地步：湖泊数量锐减；水面面积急剧缩小；湖泊淤积严重，部分湖泊逐渐沼泽化，再加上人为因素造成的水土流失，使湖泊变浅，库容量降低；生产生活污水的大量排放使湖泊水质恶化。

The experiment results shown that: 1 the smaller the pH value, the smaller the use amount of alkaline metal and the alkali earth metal electrolyte demulsifier, when the pH value was 3, the waste fluid could be demulsified no any demulsifier and the use amount of the demulsifier did not increase remarkably along with the wiredrawing fluid concentration increased. 2 Using polymeric ferric sulfate as coagulant demulsifying, when the pH value was 8.4, the best adding amount was 40 mL per liter wastewater and the best precipitation time was 4 hours. Then the COD concentration was 480 mg/L, reaching the water quality requirements to enter the sewage treatment plant.
