The toxicity of the wastewater containing xanthate discharged from flotation operation is very formidable. These effluents direct discharge will cause serious environmental pollution. This paper describes several technologies for treating these effluents by using physico-chemical method and biodegradation method,and several suggestions about how to increase the efficiency of xanthate-removal were proposed.%含有黄药的浮选废水毒性较强,直接外排将对环境造成严重污染.本文全面分析了处理含黄药废水的各种方法,并探讨了提高处理效率的途径.
