摘要
随着我国农村经济社会的发展和农民生活水平的提高,农村生活污水排放量逐年增长,导致水体环境严重恶化,迫切需要治理。本文对近年来我国已研究应用的农村生活污水处理技术进行了概括与分类,系统的分析了5类(生物法、生态法、物化法、组合工艺和一体化设备)农村生活污水分散式处理技术的原理、研究进展和难点,讨论了农村生活污水分散式处理技术发展的方向与思路。
With the development of rural areas and the improvement of peasants’ living standard,more and more rural wastewater has been discharged into the environment with the total amount increasing annually.As an important pollution source of water deterioration,rural sewage is to be treated urgently.Herein a certain summary and classification were made for rural decentralized sewage treatment technology which has developed in China recently.Furthermore,this paper systemat-ically analyzed theory,recent advances and limitation of rural recentralized sewage treatment technology including the biolog-ical treatment,ecological treatment,physic-chemical method,combined technology and integrated equipment.In addition,the developing direction of decentralized rural sewage treatment technology was discussed.
