- Abstract:
- The statistical analysis has been carried on for the national municipal wastewater treatment facilities construction, operation and investment and financing situation. The results showed that by the end of 2017, 8 591 municipal wastewater treatment plants had been built, with the wastewater treatment capacity of 230 million m3/d. The wastewater treatment rate in cities, counties and towns was 94.5%, 90.2% and 49.4%, respectively. By region, the eastern region has a relatively high level of facilities, followed by the central and western regions. Municipal wastewater treatment facilities are facing with prominent problems such as uneven distribution of regional treatment facilities, lagging construction of supporting pipe network, low wastewater collection rate in some areas and insufficient capital investment. In order to strengthen the short-board points of municipal wastewater treatment facilities, suggestions on fund raising have been put forward from the four dimensions of government, users, social capital and green finance, so as to provide decision-making reference for relevant government departments.
