摘要
介绍北京某企业技术研发中心产生的含重金属废水治理工程。在分析原水水质和外排水质要求的基础上,采用"中和沉淀—砂滤—活性炭吸附—除砷"工艺处理含重金属废水,排放废水稳定达到《北京市水污染物排放标准》(DB11/307-2005)标准限值的要求。
It is introduced that the disposal project engineering of wastewater containing heavymetals from the technology research and development centre of an enterprise in Beijing. Based on thequality requirements of the influent and effluent water, the process of ＂neutralization and precipitation-sand filtration-activated carbon adsorption-arsenic removal＂ is applied to deal with the wastewater. Theeffluent water can be stably consonant with the standard limit requirements of ＂ Beijing discharge standardof water pollutants （ DB11/307 - 2005 ） ＂
