对某地毯厂原印染废水处理系统目前存在的问题和废水水质、水量进行调研分析,在充分利用原有处理构筑物和设备,同时利用厂区周围闲置场地的前提下,提出采用水解酸化/好氧接触氧化/混凝沉淀工艺结合低运行成本的生态塘和人工湿地生态处理技术进行改造。结果表明,改造工艺经调试运行稳定,处理出水COD、BOD5、SS、色度均可达到《纺织染整工业水污染物排放标准》(GB 4287—1992)的一级标准,但氨氮排放浓度超标较为严重,针对该问题提出了进一步的解决方案。

江苏某污水处理厂面临提标扩容的任务,设计改造后总处理规模为5×104m3/d,出水水质需达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准,通过比较,选用了运行更稳定、经济效益更优的方案,将现有CAST工艺改造成A2O工艺,同时增加深度处理。改造后污水处理厂运行良好,各项出水指标均稳定达标。
