Abstract:

In recent years, the improvement of living standards in rural areas of developing countries and the continuous upgrading of rural industrial economy have led to increasingly serious rural sewage discharge. The rural sewage from production and domestic wastewater, agricultural tailwater, and aquaculture wastewater seriously damages the ecological environment, affecting residents' well-being and economic development. This paper points out the limitations of traditional ecological methods and biological treatment methods, such as long treatment cycles, significant environmental impact, and secondary pollution. Furthermore, it further discusses the advantages of plasma technology in treating rural sewage, including its wide application range, high treatment efficiency, and absence of secondary pollution, filling the gap in the application of plasma technology in agricultural wastewater treatment. Although some reaction mechanisms of plasma are still unclear, and the requirements for equipment are relatively high, which still need to be continuously improved. However, in the future, by combining with other technologies, the efficiency and application range of plasma technology can be further improved, enabling it to play a greater role in optimizing and improving the comprehensive treatment process of rural sewage in developing countries.

Key words: plasma, rural sewage, ecological treatment, biological treatment
