摘　　要：采用内蒙地区某城市污水厂二级出水为水样,在分析二级出水各项水质指标的基础上,参照电厂循环冷却水的水质标准,确定了污水回用工艺流程,并对混凝处理进行了试验研究.结果表明,混凝处理对浊度、CODcr的去除效果较好,去除率最大分别可以达到68.5%和30.7%,而对氨氮的去除率最大可达7.3%,需进一步强化后续过滤工艺.Secondary effluent from a city sewage plant in Inner Mongolia is taken as water sample in the study. With reference to requirements of the power plant for the quality of circulating cooling water,wastewater reuse process is devised and an experimentalinvestigation on coagulation is carried out. Results show that the coagulation process manifests good effect on removal of turbidity and CODcr. The maximum removal efficiency reaches 68. 5% and 30.7% respectively. But the removal amount of ammonia nitrogen does not seem quite desirable ,the maximum being 7.3%. To heighten the removal ,filtration process is demanded.
