摘要 根据五氯苯酚(PCP)在活性污泥中吸附和共代谢降解的规律设计出吸附-共代谢再生活性污泥法去除污水中五氯苯酚的新工艺。小试发现:新工艺对污水中的PCP具有较好的去除效果,采用该工艺处理含2mg/LPCP的生活污水,如果在再生段添加50mg/L的谷氨酸作共代谢诱导基质,在稳定运行期间出水PCP的浓度可以达到低于0.2mg/L的水平。 Based on the mechanism of pentachlorophenol (PCP) adsorption and cometabolism in activated sludge system, a new sludge process to enhance PCP removal was described. Results showed that it was feasible to remove PCP from domestic wastewater by biosorption-cometabolism stabilization process. When loaded domestic wastewater with 2mg/L PCP, if 50mg/L glutamic acid was added in stabilization process, the concentration of PCP in effluent water could be under 0.2mg/L.
