城镇污水处理厂“准Ⅳ类”标准提标改造技术简析
|
摘要
通过对现有污水处理技术综合分析,梳理适用于"准Ⅳ类"污水排放标准的技术工艺,为污水处理工程技术选择提供支持。首先梳理了我国城镇污水排放标准的发展沿革,搜集整理了几个重点区域及流域新近颁布的"准Ⅳ类"标准,结合部分代表性污水处理厂的实际运行效果,提出本次提标改造的核心问题为COD和TN的深度去除。由此,分别从一级处理、二级处理和深度处理3个方面全面梳理了适用于"准Ⅳ类"标准的提标改造技术,并提出应该充分考虑污水处理各工艺的特点和对污染物的处理能力,将各工艺段进行有机结合,最终出水达标排放。
In order to recommend the technologies and processes suitable for "quasi-category Ⅳ" wastewater discharge standard,detailed analysis of the current wastewater treatment technologies was carried out,so as to provide support for wastewater treatment technology selection. The evolution of urban wastewater discharge standards of China was firstly introduced,the newly issued "quasi-category Ⅳ" standards in several key areas and drainage basins were collected and sorted up,and in combination with practical operation effects of some wastewater treatment plants,the core problems of upgrading and reconstruction this time were presented: tertiary treatment of COD and TN. The upgrading and reconstruction technologies suitable for "quasi-category Ⅳ" standard were reviewed in terms of primary treatment,secondary treatment,and tertiary treatment,and it was recommended to fully consider the characteristics of wastewater treatment processes as well as their abilities to treat the pollutants,and flexibly combine each process zone,to finally realize the up-to-standard discharge.
