UNITANK工艺在城镇污水厂中的应用
Discussion on the Application of Unitank Technology in Wastewater Treatment Plant
【摘要】 苏州市某城市污水处理厂第一期建设的生物池采用UNITANK工艺,设计之初执行的是GB18918—2002中一级B排放标准。而随着之后二期改良型UNITANK工艺及三期深度处理的建成,使得最终出水排放标准提升至一级A。通过调整一期各段运行周期,使其达到良好的脱氮除磷效果,出水水质稳定排放。
【Abstract】 Suzhou the first stage of a city sewage treatment plant to use the Unitank process, the design was implemented at the beginning of the GB18918-2002 Level B emission standards. With the completion of the two-phase modified Unitank process and three-phase advanced treatment, the final effluent discharge standard is upgraded to a. By adjusting the operation period of the first stage, the effect of nitrogen and phosphorus removal is good, and the effluent quality is discharged stably.
