农村生活污水处理微生物强化技术研究进展

 目前中国农村人居环境不一，环保意识不到位，基础设施差，农村生活污水的排放量不断增加，加剧了农村环境污染程度。通过分析国内外农村生活污水的处理工艺技术，阐述了培育高效降解菌种技术、微生物固定化技术、构建微生物菌剂技术等微生物强化技术治理农村生活污水的原理、特点和技术难点，并结合案例分析，表明微生物强化技术能有效防止污泥膨胀，比传统污水处理方法效率更高，具备抗逆性、抗毒性和耐负荷冲击能力强等优点，更适用于农村水生活污水的治理。

Research progress of microorganism intensification technology for rural domestic sewage treatment

At present, with the variety of China's rural living environment, the lack of environmental awareness for many farmers, and the poor infrastructure, the rural domestic sewage is continuously discharged to aggravate the environmental pollution in rural areas. This paper analyzes the present status of the domestic sewage treatment in rural areas at home and abroad, in the context of the application principles, the characteristics, and the commonly used methods of microbial enhancement technologies, including the high-efficiency degrading technology, the microbial immobilization technology, and the microbial inoculation technologies, which can effectively prevent the sludge from swelling with many advantages, such as the higher treatment efficiency, the resistance to stress, the resistance to toxicity and the impact resistance to load, as compared with the traditional sewage treatment methods. It is shown that the microbial enhancement technology is more suitable in the rural domestic wastewater, for the treatment of domestic sewage.
