摘　　要：碳源不足是污水处理中常见问题,添加低成本高效碳源对降低污水处理成本至关重要。通过模拟和应用实验,对一种新型高能碳源在污水处理中的效能进行了探究。结果表明,该碳源以有机钾盐替代钠盐,不含氯离子和As、Pb、Cd等污染元素,具有环境友好的特点。该碳源的应用能够有效降低污水中的COD、TN、TP和NH^+_(4)-N,污染物的整体去除效率优于使用传统的乙酸钠碳源。使用该碳源的吨水处理碳源成本比乙酸钠低56.5%,具有良好的应用前景。Insufficiency of carbon source is a common problem in sewage treatment.Adding low-cost and high-effici-ency carbon sources is essential to reduce the cost of sewage treatment.Through simulation and application experi-ments,the efficiency of a new high-energy carbon source in sewage treatment was investigated.The results showed that this carbon source used organic potassium salt instead of sodium salt,and did not contain chloride ions and po-llution elements such as As,Pb,and Cd,with environmental friend characteristics.The application of this carbon sou-rce could effectively reduce COD and the concentrations of TN,TP and NH^(+)_(4)-N of the sewage.And its overall remo-val efficiency of various pollutants was better than adding traditional sodium acetate carbon source.By using this car-bon source,the cost of carbon source for treating a ton of sewage is 56.5%lower than that of sodium acetate,which has an excellent prospect for application.
