摘要
为响应国务院2015年发布的《水污染防治行动计划》,各地政府陆续出台相关新的城镇污水厂排放标准,加快了城镇污水处理厂提标改造的步伐。本文对当前城镇污水处理厂在提标改造中可供采用的深度处理工艺进行了研究和总结,其中重介质混凝沉淀技术可用于高效去除TP;活性炭吸附技术主要用于COD高效去除;过滤技术与湿地生态技术可用于同步去除多种污染物。在深度处理过程中,常采用组合工艺以达到最优效果。
In response to the 2015"Action Plan for Water Pollution Prevention and Control"issued by The State Council,local governments have successively implemented relevant new discharge standards for urban sewage plants and accelerated the upgrading of such facilities.This paper examines and summarizes advanced treatment technologies that can be used in upgrading urban sewage treatment plants.Among them,heavy medium coagulation and precipitation technology is effective in removing TP,while activated carbon adsorption technology is mainly used for efficient removal of COD.Filtration technology and wetland ecological technology can be used to remove various pollutants simultaneously.In the advanced treatment process,the combination process is often used to achieve the best results.
