摘　　要：通过对陕北某污水处理站各处理单元出水水质分析，评价了处理工艺流程运行的稳定性，指出了水处理系统存在的问题，提出了工艺改进措施。结果表明：通过减小过滤器滤料的颗粒粒径、药剂体系的优化以及加强处理系统的管理等措施，处理后水到达注水井井口时的悬浮物含量、含油量和总铁含量由改进前的40-60mg／L、165-185mg／L和15．56-17．44mg／L降低到了0．7～0．9mg／L、2．0-4．3mg／L和0．09-0．32mg／L，达到了回注水水质标准。Through the analysis of yielding water quality of different units at some sewage treatment stations in northern Shaanxi, the evaluation is carried out about the stability of operational treatment technology. Then some problems existing in the sewage treatment system are presented, followed by some improving measures of technology. The results show： by means of the measures like reducing the particle diameter of filter material, optimizing the medicine agent system and strengthening the management of treatment system, the contents of suspended substance, oil-bearing and total iron have dropped to 0,7-0.9mg/L, 2.0-4.3mg/L and 0.09-0.32mg/L from 40-60mg/L, 165-185mg/L and 15.56-17.44mg/L before the improvement, reaching the quality standards of re-injection water.
