摘要： 采用壳聚糖改性活性炭纤维毡处理含铜模拟废水，考察了其对Cu²⁺的去除效果及电化学再生效果。吸附试验结果表明，当pH=3，温度为30℃，Cu²⁺初始质量浓度为100 mg/L，吸附时间为8 h时，出水Cu²⁺<0.5 mg/L，达到《污水综合排放标准》（GB 8978-1996）一级排放标准要求。电化学再生试验结果表明，在优化条件下，经再生的壳聚糖改性活性炭纤维毡对Cu²⁺的去除率达72.39%。

Abstract: The chitosan-modified activated carbon fiber felt has been used for the treatment of copper-containing wastewater,and its removing effect on Cu²⁺ and electrochemical regenerating effect investigated. The adsorption experiment results show that when pH=3,temperature 30℃,Cu²⁺ initial mass concentration 100 mg/L,and adsorption time 8 h,the effluent concentration of Cu²⁺ is less than 0.5 mg/L,reaching the first-level discharge standard specified in the Integrated Wastewater Discharge Standard(GB 8978-1996). The electrochemical regeneration experiment results show that under optimized conditions,the removing rate of the regenerated chitosan-modified activated carbon fiber felt on Cu²⁺ reaches 72.39%.
