大型印染污水厂深度处理研究

Study on Advanced Treatment of Large Dyeing Wastewater Treatment Plant

目前的污水排放指标已不能满足新标准的要求,必须进行改造升级,达到《城镇污水处理厂污染物排放标准》一级B排放标准。针对印染废水深度处理需求和传统技术存在的问题,现使用超滤膜加多金属催化生物焦还原氧化的深度处理工艺,并通过试验数据,分析工艺效果。

Current sewage discharge indicators have been unable to meet the requirements of the new standards, must be transformed and upgraded to achieve the ＂urban sewage treatment plant pollutant discharge standard＂ level B emission standards. According to demand and traditional technology of printing and dyeing wastewater treatment, now using ultrafiltration membrane Cadogan metal catalyzed biological focal reduction oxidation advanced treatment process and based on the experimental data. Analysis process effect.
