【Abstract】Water， which is the most important source material basis for the mankind and all living things， has been seriously damaged because of the industrial development in Ningbo. To overcome the difficulties and improve efficiency， Hua Xing Village and Zong Han Street， which is the village in Ningbo， invented their personal new technologies. Nevertheless， the effect of the reform is not conspicuous due to the lack of awareness and incomplete system. A questionnaire and an interview were conducted among villagers and cadres in two villages. Eventually， some suggestions are put forward in the discussion part.The article is mainly to analyze not only the implementation of the new technology in these two villages，， but also the comparison of the old and new technologies！

　　1. Introduction
　　Water， which is the basic natural resources， strategic economic resources and social resources， is the most important material basis for the survival and development of human beings and all living things. However， with the continuous development of the economy， Ningbo’s water resources have been seriously damaged. The continuous deterioration of the water environment in the river network has seriously affected the people’s quality of life and the process of modernization.[Hu Yang， ZhengXuefang， 2004]In order to promote the controlling of rural domestic sewage， Ningbo has invested a lot of manpower and material resources， but affected by farmers’ living habits， the concept of government management and other factors， the treatment effect is not ideal. The quality of some rivers is still very low.In this regard， the relevant villages have carried out reforms and innovations. The inventions of new technology， which are aerobic and anaerobic in Huaxing Village， and cultivation of microbial species in Zonghan Street， came out.
　　2. Processand results
　　I interviewed two key cadres of the Environment Bureau of the two villages to get some useful data on water quality from cadres. In addition， I also carried out a questionnaire ，which is about the understanding of the five-water co-governanceand their own participationon the villagers of the two villages.
　　From January to June 2018， the overall quality of surface water in the city was good. Among the 80 municipal control sections， classⅠ-Ⅲ water quality sections accounted for 76.3% and the rate of reaching the standard in water functional was 80%.It is gratifying to know that most of the villagers can actively participate in the ranks of sewage treatment and the cadre said that there are more than 580 households in the village and the total amount of sewage discharged is large. The terminal treatment facility of the domestic sewage treatment project adopts mature and reliable aerobic anaerobic-constructed technology. And the residents' domestic sewage is uniformly collected and incorporated into the centralized treatment system of the sewage treatment system， and the treated water quality index reaches the first class B standard of the National Pollutant discharge Standard for urban sewage treatment plants.Compared with the old technology， the technology has a better cleanup capabilities and less manpower consumption， although it is more expensive and more difficult than the old technology. The microbial strain project in Zonghan Street is organized and implemented by the Provincial Water Conservancy Science. It mainly adopts a variety of dominant environmental microbial populations screened from nature. After directional domestication and cultivation， it is used to degrade pollutants in water. So， the water can restore the self-purification capacity. It is reported that this is still the first application in the province， and it will play an exemplary role in the river regulation throughout the province.
