摘要
采用电解絮凝法对气田废水进行了治理研究,探讨了其反应机理,并通过实验确定了适宜的工艺条件.实验结果表明,电解絮凝法处理气田水,作为一级处理CODcr去除率可达到50%～60%,作为二级处理CODcr去除率可达到70%～80%,其工艺具有不需投加任何化学药剂、操作简单的特点,为气田废水的治理提供了一条新途径.
It has been raised a new method,electrocoagulation in disposition of gas-field wastewater.The reacting mechanism and condign technological conditions have been studied in the lab.Results show that the main pollutant CODcr removal rates of gas-field wastewater are 50%~60% when take this technique as first-order reaction,while CODcr removal rates can reach 70%~80% when as secondary reaction.In addition,this process requires simple facilities and no additional chemical agent.
