Treatment and technology of domestic sewage for improvement of rural environment in China

Abstract

It has been recorded that China’s rural environment threatened the lives of people due to the large amounts of wastewater treatment. The domestic sewage treatment plants were implemented in many parts of China to improve the environment of the country, and it has been noted that this sewage had a positive effect on the Chinese Rural Environment. Past studies recorded that China reached building sewage treatment plants with the capacity of 125 million m3. Moreover, most of these treatment plants employed Activated Sludge Process (ASP) along with the package treatments such as Anoxix-Oxic processes, Anaerobic processes, Oxidatin Ditch, and Sequencing Batch Reactors. Still there seems to be a gap in the effectiveness of wastewater treatment plants constructed with wastewater rising day-to-day. The main purpose of the current study is to review the rural wastewater treatments such as sewage systems and other treatment plants, which will improve the rural environment in China. This paper also highlights the characteristics of rural domestic sewage treatment. Furthermore, this paper also explores the applicability of rural sewage treatment technology in rural places of China. The challenges of the wastewater treatment in rural areas of China will also be closely monitored by the researcher.
