【摘要】 针对实际化学镀镍废液的特点，采用石灰作为沉淀剂，通过控制ｐＨ＝１２、温度８０ ℃、反应时间１小时，可以将废液中镍含量由１２００ｍｇ／１降至１ｍｇ／１，低于国家排放标准。还对沉淀法产生的沉渣的处理方法进行了初步探讨。更多还原

【Abstract】 On the basis of the characteristica of electroplating wastes, the concentration of nickle was reduced by lime (sedimentation agent) from 1200mg/1 to 1mg/l under the condition of pH= 12, T=80 ℃ , t= 1h. The treatment method of sludge produced by sedimentation process was primarily probed.更多还原
