three. Gradual development of rural domestic sewage and toilet sewage treatment <br>Rural domestic sewage treatment started late. The bottlenecks restricting the effective control of rural pollution are mainly insufficient funds, lack of scientific planning, lack of effective organization, lack of technical standards, and lack of long-term management. From a technical point of view, the technology of urban sewage treatment plants is not applicable, so it is necessary to study and summarize the decentralized sewage treatment technology that is truly suitable for rural areas. Management lacks corresponding procedures, norms, guidelines and standards; in terms of mechanisms, rural sewage treatment facilities lack effective input and long-term operation mechanisms. Since 2015, the Ministry of Housing and Urban-Rural Development has taken a step-by-step approach, starting with economically developed areas and rural areas surrounding urban suburbs, gradually expanding to other areas, carrying out demonstration and promotion work, and beginning to organize demonstrations of rural domestic sewage treatment.

The main bottlenecks restricting the effective control of rural pollution are lack of funds, scientific planning, effective organization, technical standards and long-term management. From the technical point of view, the technology of urban sewage treatment plant is not applicable, so it is necessary to study and summarize the decentralized sewage treatment technology which is really suitable for rural areas. In terms of management, there is a lack of corresponding procedures, norms, guidelines and standards; in terms of mechanism, there is a lack of effective investment and long-term operation mechanism for rural sewage treatment facilities.
