摘　　要：新市镇污水处理厂是以印染废水为主的城镇污水处理厂,在长三角地区具有一定的代表性,COD去除是其难点。在该污水处理厂开展了提标改造小试,历时3月有余,结果表明,通过适当延长现有MSBR的沉淀时间,系统可以稳定维持高浓度活性污泥,从而显著提高其去除COD的能力;若再辅以深度处理设施,可以保证出水水质达到一级A标准要求。Xinshi WWTP is a typical printing and dyeing wastewater treatment plant in the Yangtse delta, and COD removal was a difficult problem. Small-scale tests for upgrading in the WWTP were con- ducted for three months. The results indicated that the high-concentration activated sludge could be stably maintained by extending settling time of the existing MSBR to increase COD removal. If assisted by the advanced treatment facility, the effluent could meet the first level A criteria.
