菌藻一体化系统在农村生活污水处理中的发展前景

Development Prospect of Bacterial-algal Integrated System in Rural Domestic Sewage Treatment

目前我国农村生活污水的排放量随着经济发展而逐步增加,但大部分农村地区暂未建立起有效的污水处理系统,生活污水直排沟、渠、塘、河等附近水域,农村水环境系统被破坏。菌藻一体化系统能有效利用菌藻共生关系,通过其中藻类光合作用释放出氧气供其他微生物利用,实现节能降耗,通过菌藻的生长吸收氮磷、降解有机物实现水体的净化。本文从目前我国农村生活污水的处理现状、菌藻一体化系统的机理及研究应用现状等方面分析了菌藻一体化系统的发展前景。

At present, the discharge of domestic sewage in rural areas of our country is gradually increasing with the development of economy, but most rural areas have not yet established effective sewage treatment system, domestic sewage directly discharged ditches, ditches, ponds, rivers and other adjacent waters, the rural water environment system has been destroyed. The bacteria-algal integrated system can effectively utilize the symbiosis between bacteria and algae. Through the photosynthesis of algae, oxygen is released for other microorganisms to use, so as to save energy and reduce consumption, and through the growth of bacteria and algae, nitrogen and phosphorus are absorbed and organic matter is degraded to achieve water purification. In this paper, the development prospect of the bacterial-algal integrated system is analyzed from the current situation of domestic sewage treatment in rural China, the mechanism and research and application status of the system.
