摘要
根据危险废物填埋场渗沥液的水质、水量特点,提出了氧化还原-絮凝沉淀-砂滤-活性炭过滤-二氧化氯消毒的处理工艺,该工艺投资少、处理效果稳定、运行费用低,废水处理后第一类污染物达到GB8978—1996污水综合排放标准表1中要求,其余特征污染物达到该标准表4中一级标准要求后排入市政污水管网。
A process design of redox-coagulation and sedimentation-sand fihration-activated carbon filtration-chloride dioxide sterilizing was put forward based on characteristics of water quality and quantity of leachate from hazardous waste landfill site. This design have many advantages such as little investment, stabilization of treatment efficiency, low cost of operation. The first kind of pollutants can reach the standard of table 1 in Integrated Wastewater Discharge Standard （GB8978-1996） after treatment, and other kinds of characteristic pollutants can discharge into municipal sewage pipe after reach to the primary standard of table 4.
