水解酸化-活性污泥法处理印染废水研究

Study on treatment of printing and dyeing wastewater by hydrolysis and acidification-activated sludge

以江苏某印染企业废水工程为例,探讨了水解酸化-活性污泥法在印染废水处理中的应用。结果表明该工艺可以较好地解决PVA、染料的处理问题,印染废水处理后达到《纺织染整工业水污染物排放标准》(GB4287-92)一级排放标准。与传统的物理化学-生化法相比,该工艺具有处理效率高、运行稳定、动力消耗低和污泥量少等优点。

The practical engineering effect of treating printing and dyeing water with hydrolysis and acidification-activated sludge system was introduced and discussed.It showed that the system has advantages on removing PVA,man-made fibre and alkali materials,new-style aid reagent,which are difficult to be degraded.After treatment the effluent could reach the first grade discharge standard of Water Pollutants for Dyeing and Finishing of Textile Industry（GB4287-92）.
