摘　　要：论述了利用活性炭吸附法处理含铬电镀废水方法,通过试验找出了最佳吸附条件,确定了吸附剂的用量;吸附时间以及试液pH值对铬去除率的影响;得出了活性炭对铬的吸附等温方程式;对铬的回收提出了初步的设想。This paper presents a method for disposing the electroplate wastewater containing chromium with the active charcoal adsorption. Through the experiment the authors find out the best absorbing conditions, determinethe consumption of the absorbent,the time of absorption and the influence of pHvalue of test solutions on the chromium removing rate. The isothermal equation of absorbing chromium of the active charcoal is derived and the preliminary ideato recovery the chromium is put forward.
