印染污水处理设备的关键
印染污水处理设备的关键

  预处理工艺主要包括调节、中和、废铬液处理与染料浓脚水预处理等;而生物处理工艺主要为好氧法,目前采用的有活性污泥法、生物接触氧化法、生物转盘和塔式生物滤池等。为提高废水的可生化性,缺氧、厌氧工艺也已应用于印染废水处理中。常用的物化处理工艺主要是混凝沉淀法与混凝气浮法。此外,电解法、生物活性炭法和化学氧化法等有时也用于印染废水处理中。但通过此类工艺处理的纺织印染废水,最多只能达标排放,不可能达到回用水水质标准作为纺织印染的工艺用水。污水处理设备公司山东海龙智能。

  由于国家新的排放标准的执行,印染工业废水经厌氧—好氧工艺处理不能保证新的排放要求(CODcr<100 mg/l,色度<50倍),同时考虑占地、投/资、运行成本等问题,选择增加CQJ型浅层离子气浮作为预处理及三级深度处理工艺主要设备,达标排放的把关措施。从实际运行情况来看,CQJ型浅层离子气浮是最/佳选择。污水处理设备公司为您介绍,欢迎您咨询。
