污水厂升级改造设计研究
摘 要:随着城市现代化的飞速发展,人们生活水平不断提高。全国各污水处理厂的排水标准也逐渐从《城镇污水处理厂污染物排放标准》(GB18918—2002)一级B标准升级到一级A标准。污水处理厂通过一系列的改造升级以达到出水水质标准。

Abstract: With the rapid development of urban modernization, people#39;s living standards continue to improve. The drainage standards of various sewage treatment plants across the country have also gradually upgraded from Grade B standards to Grade A standards in the 'Emission Standards for Pollutants from Urban Wastewater Treatment Plants' (GB18918-2002). The wastewater treatment plant has been upgraded to meet the effluent quality standards.

随着我国水资源日益短缺与人们日常生活对水资源需求量的日益提高,城镇污水的循环利用逐渐得到了人们的重视。城市污水回用可用于农业灌溉、工业生产、景观用水、回灌地下水、城市生活用水等[1]。显然,污水是一项十分重要的资源,它的水量稳定,供给可靠。因此,城市污水回用成为增大资源利用,缓解日益严重的水资源供需矛盾的一种性价比较高的措施。于是,需要对污水处理厂进行提标改造。
