机械厂电镀废水治理工艺改造工程实例分析

Engineering Case Analysis of Electroplating Wastewater Treatment Process Improvement in a Machinery Plant

指出了某机械公司现有电镀废水治理工艺落后,出水难以实现稳定达标排放,结合该厂的实际情况,对现有工艺进行了改造,采用铬水处理系统、氰水处理系统、综合水处理系统、生化处理系统、回用水系统进行分类处理。半年的实际运行结果表明:整套工艺运行平稳,出水各项指标可以达到《电镀污染物排放标准》(GB21900-2008)的排放要求。

This paper pointed out thatthe existing polluted water treatment technology and system on then galvanization process of a certain company which manufactures machinery are not yet fully developed thus we failed to achieve the target of an effective and correctly installed sewage system. To correct and update the current technology and system for the realization of the company＇s vision, we applied the system of chromium water treatment, cyanide wa- ter treatment, integrated water treatment, biochemistry treatment, and water recycle system to distribute and deal with them respectively. Thehalf--yearactualrunning showed that the whole system works and runs smoothly, reac- hing the target of all data within the emission requirements of 〈Emission Requirements of the Discharge Standard for Pollutants after Galvanization〉 （GB21900-2008）after an operation for half a year.
