城镇污水处理工艺的主要污染物去除效率分析

Analysis of the Removal Efficiency of Major Pollutants in Urban Sewage Treatment Process

国家针对生活、生产污水的处理制定了非常严格的标准,现有的城市污水处理工艺标准与国家颁布的《城镇污水处理厂污染物排放标准》[1]中的一级A标准有较大差异。当前的城市和乡镇,无论是生活还是工业排放的污水都需要集中通过污水处理厂完成污水的处理,通过适当的净化处置,满足污染物净化及排放要求。由此可以看出,污水处理厂是当前城镇环境保护工作的重要环节,同时也是避免水资源流失的不可或缺的基础设施。污水处理厂使用何种方式完成对污水的处理、及时排除污染物是污水处理过程中需要深入研究的问题。基于此,本文针对污水处理工艺对污染物的去除效率进行了相关分析与总结。

The state has formulated very strict standard requirements for domestic and production sewage treatment, and there is a certain gap between the current implementation standard of urban sewage treatment process and the requirements in the first-level A standard of the “Urban Sewage Plant Pollutant Discharge Standard”[1] issued by China. At present, the sewage discharged by cities and towns,whether it is domestic or industrial, needs to be concentrated through sewage treatment plants to complete the treatment of sewage, and the polluted water sources discharged can be purified through appropriate purification and disposal to meet the requirements of pollutant purification. It can be seen that sewage treatment plants are the main part of environmental protection in cities and towns, and they are also indispensable disposal places to avoid water loss. Based on this situation, this paper analyzes and summarizes the efficiency of sewage removal in the sewage treatment process.
