铸铁/焦炭反应器处理电镀混合废水工程

采用铸铁／焦炭反应器成功处理了广东省东莞市某电镀厂规模为800m^3/d的电镀混合废水。在设计工艺条件下，总氰化物、Cr^6 、总铜和总镍等主要污染物去除率分别达99．7％、85．0％、98．8％和99．6％，出水水质稳定达到当地环保一级排放标准。与传统的电镀废水分开作预处理工艺相比，该工程具有流程简单、投资及运行费用低、占地少、操作管理简便等优点。

Application of cast iron/coke reactor to the treatment engineering of plating mixed wastewater

The plating mixed wastewater at 800 m3/d in the plating plant is treate d successfully with cast iron/coke reactor in Dongguan city Guangdong Province. Under the conditions of designed process, the removal ratio of main pollutants s uch as total of cyanide, Cr6+, Cu, Ni is respectively 99.7%, 85.0%, 98.8% and 99 .6%. The drainage water quality is up to the local environmental protection stan dard of primary drainage. Compared with the treatment process of traditional pla ting wastewater which is pre-treated separately, it has the following characteri stics: simple process, low expense of investment and operation, small area, conv enience of management in this engineering.
