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.
