摘要
随着人们生活水平的提高,生活污水成为重要的污染源.对于人口密度低和分散家庭而言,集中型污水收集和处理系统基建和运行费用较高,而分散型污水处理系统比较适合,运行可靠且费用低廉.介绍了近年来出现的各种分散型污水处理系统,主要包括化粪池、自然处理系统和人工处理系统.各地可根据实际情况选择最适宜的分散型污水处理系统.
With the improvement of people＇ s living standard, domestic sewage nas Decom an important pollution source. Centralized wastewater collection and treatment systems are costly to build and operate, especially in areas with low population densities and dispersed households. Alternatively, the decentralized system is not only a long- term solution for small communities but is more reliable and cost effective. This paper presents a review of the various recent decen- tralized domestic sewage treatment systems, including septic tanks, natural wastewater treat- ment system and artificial wastewater treatment system. The most suitable decentralized system can be chosen accordingly.
