改良型A_2/O工艺处理印染废水的研究

Study on Treatment of Printing and Dyeing Wastewater by Modified A_2/O Process

阐述了南闸综合污水处理厂废水处理工艺的改良过程,经厌氧+缺氧/好氧+絮凝沉淀+转盘滤池工艺改良后,不仅使出水水质稳定,而且达到了《城镇污水处理厂污染物排放标准》GB18918-2002的一级A标准。

This paper expounds wastewater treatment plant improvement of the Nanzha WWTP. Improved process is the process of anaerobic ＋ anoxic/aerobic ＋ flocculating sedimentation ＋ fiber rotary disc filter. Wastewater to he treated is a comprehensive wastewater composed of printing and dyeing wastewater. The effluent quality stably reached the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918-2002 ）.
