摘要
根据含油废水的特性 ,结合中国长城铝业公司废水处理的现状及水质特点 ,论述了采用捞油→撇油→隔油→混凝气浮的工艺处理铝冶炼企业含油废水的可行性 ,并对此工艺进行了剖析。多年的运行经验证明 ,采用此工艺可去除水中的可浮油与乳化油 ,去除率可达 98%左右。油浓度低于国家污水排放标准 10mg/L。此工艺为铝工业废水治理开辟了一条崭新的道路。然而 ,此工艺在具体设计和运行管理上仍存在一些问题 。
The feasibility of dealing with the oil bearing wastewater in alumina smelting manufacture by using scooping oil out→skimming oil→isolating oil→coagulating gas floatage in accordance with the property of the oil bearing wastewataer,and the conditions of China Great Wall Alumina wastewater dealing process as well as the water quality have been analysed. The process of it has also been analysed. After several years running,it shows that the floating oil and soluble oil can be dislodged from the water, the ratio of deoil can reach about 98%. The concentration of the oil is lower than 10 mg/L(national wastewater unloading standard). This process initiates a new way for wastewater dealing. But,this process also has some problems in practical design and running management. It will be perfect step by step.
