中国污水处理设施发展现状分析

Analysis of development status of sewage treatment facilities in China

面对我国存在的水资源紧缺、水环境日趋恶化等问题,污水处理厂的系统布局对促进水资源的高效、可持续利用起着至关重要的作用。目前,我国已建成投运污水处理厂4436座,日处理能力达到1.7亿m^3,污水处理水平已经基本与美国持平,但由于区域自然条件、管网铺设情况等诸多原因,表现出了明显的区域差异特征,负荷率较低等问题是影响污水处理设施效率的重要瓶颈,因此,提高运营负荷率是当前急迫的主要任务。

Facing the shortage of water resources and the worsening water environment in our country, the system layout of sewage treatment plants plays an important role in promoting the efficient and sustainable utilization of water resources. At present, China has built 4436 sewage treatment plants, daily processing capacity of 170 million cubic meters, sewage treatment level has been basically the same with the United States, but due to natural conditions in the region, the laying of pipe network and many other reasons, showing obvious regional difference characteristics, load a low rate of sewage treatment is an important bottleneck. Therefore, improve the operation efficiency of the facilities, the load rate is the main task of the urgent.
