摘要
随着我国社会经济水平的不断发展,城市化与工业化的发展越来越迅速,城镇的人口与日俱增,而城镇生活污水问题也就变得越来越严重,处理难度也大大增加。据统计,城市中人均每天排出的城镇生活污水总量约为150~400L,污水的水量和水质与当地人们的生活水平密切相关。若不进行妥善收集处理,城镇生活污水不但会对下游城镇的水源造成污染,造成水体环境逐渐恶化,还会给城镇生活污水的处理工作增加负担。总而言之,城镇生活污水的处理问题与广大群众的日常生活具有紧密的联系。本文介绍了城镇生活污水特点和影响,以及几种常用的污水处理工艺,希望本文介绍的污水处理技术能够为当前城镇生活污水处理工作提供帮助。
With the continuous development of China’s social and economic level, the development of urbanization and industrialization is becoming more and more rapid, the population of urban areas is increasing day by day, and the problem of urban domestic sewage is becoming more and more serious, and the difficulty of handling is greatly increased. According to statistics, the total amount of urban domestic sewage discharged per capita per day in the city is about 150 to 400 liters. The amount and quality of sewage are closely related to the living standards of local people. Without proper collection and treatment, urban domestic sewage will not only pollute the water sources of downstream towns, but also cause the water environment to gradually deteriorate, and will also increase the burden on the treatment of urban domestic sewage. All in all, the treatment of urban domestic sewage is closely related to the daily life of the masses. This paper introduces the characteristics and impacts of urban domestic sewage, as well as several commonly used sewage treatment processes. It is hoped that the sewage treatment technology introduced in this paper can help the current urban domestic sewage treatment work.
