Ji'nan's water pollution prevention roadmap will delineate groundwater prohibition mining area
recently, the Ji'nan municipal government issued the implementation plan for the implementation of the action plan for the prevention and control of water pollution in Ji'nan, and gave the road map and timetable for the prevention and control of water pollution. It is understood that by the end of 2018, Ji'nan will complete the relocation, transfer or shutdown of chemical enterprises such as the Ji'nan Shengyuan chemical fertilizer Co., Ltd. and the Ji'nan run Chemical Co., Ltd. in the eastern old industrial zone by the end of 2018. In addition, the city, county (city) district will open drinking water safety information to the public from 2016 to 2018.
the elimination of urban 40% "odour ditch"
at the end of this year is an important step in the prevention and control of water pollution and the construction of sewage treatment facilities. By the end of this year, Ji'nan will complete the new and expanded task of three sewage treatment plants of Dajin sewage treatment plant, Guangda water (Ji'nan) Limited company and Ji'nan Kecheng water purification Co., Ltd., and the capacity of 150 thousand tons / day of sewage treatment will be added. Before the end of 2020, all the key towns in the city and along the south to North Water Transfer, the Xiaoqing River Basin and the southern mountain core areas will realize "one town and one factory". Ji'nan proposed that by the end of this year, the elimination ratio of black and smelly water bodies in the urban built-up area will reach the task of controlling the black and odorous water body before the end of next year, and the black and smelly water body will be within 10% of the water body before the end of next year.
"double control"
in the prevention and control of industrial pollution, Ji'nan will completely eliminate the production projects of small paper, tannery, dyeing, dyestuff, coking and other serious polluted water environment that do not conform to industrial policy by the end of the year. By the end of next year, all kinds of industrial gathering areas will fully realize centralized sewage treatment and install automatic on-line monitoring devices.
it is understood that Ji'nan will be completed by the end of next year, the area of groundwater prohibited mining, restricted mining area, over mining area and land subsidence control area delineation work. In the above implementation plan, it is proposed that new water intake for agriculture, industrial construction projects and service industries will be prohibited in the spring area or in the groundwater over mining area. In addition, Ji'nan will also designate yellow, orange and red early-warning lines for groundwater level in key groundwater type drinking water sources and Ji'nan spring area, and strictly implement "double control" of water intake and water level. The new project shall not take up the urban waters
the above implementation plan. It will plan the 39 square kilometer Daming Lake pilot area and the 62 square kilometer Jinxi extension area according to the functional requirements of the "seepage, stagnation, storage, net and row" of the sponge City, and carry out the model of the low impact opening and construction, and carry out the urban water as a whole. The system, garden green space system, road traffic system, building district system construction, carry out the Qianfo Hill park scenic area green space and the street green space promotion and transformation, the Second Ring South Road, such as the construction of the municipal road project pervious pavement, the construction and the existing construction district permeable transformation, Zeng Dayu water infiltration, gradually realize the urban rainwater collection. The utilization rate of reclaimed water in the pilot area reached 25%.
Ji'nan proposed that new projects should not take up urban waters, and land exploitation and utilization should be kept in the management and protection range of rivers, lakes and wetlands. Illegal crowding should be withdrawn within a limited period of time to ensure that the urban planning areas retain a certain proportion of water area.
heavy polluting enterprises will be relocated and rebuilt and closed to
relocation of old industrial areas in the East. It is reported that Ji'nan will work out an exit scheme for heavy pollution industry in urban built-up areas to guide enterprises with heavy pollution, such as iron and steel, petrochemical industry, to relocate, transform or shut down according to law. Before the end of 2018, we completed the relocation, transfer or shutdown of chemical enterprises, such as Ji'nan Shengyuan chemical fertilizer Co., Ltd. and Ji'nan moisten Chemical Co., Ltd. in the eastern old industrial area.
the above implementation plan also suggests that the government and the water supply units at the county level and above should regularly monitor, inspect and evaluate the drinking water safety status of the drinking water source, water supply plant effluent and the water quality of the user faucet in accordance with the national and local standard requirements. The City and county (city) areas are to the society from 2016 to 2018, respectively, from 2016 and 2018. Information on the safety of drinking water will be disclosed.
large residential area or construction of "constructed wetland"
it is understood that Ji'nan will choose the suitable location of the tributaries into the main stream and the river into Hukou, so as to build the water quality purification project of the artificial wetland and enhance the environmental carrying capacity of the basin. In the urban sewage treatment plant (station), key enterprises and institutions, the construction of large community sewage outfall and urban landscape, the water quality purification project of artificial wetland in the residential area with a building area of more than 100 thousand square meters has been popularized to improve the water quality purification project of the small constructed wetland, which is the main purpose of improving the living environment.
in strengthening enterprise supervision, Ji'nan will energetically implement the "red and yellow card" management of pollutant discharge enterprises, check the pollution of various industrial enterprises one by one, give a "yellow card" warning to the enterprises exceeding the standard and the excess amount, and limit the production or stop regulation to the enterprises which are still unable to reach the requirements and have serious circumstances after the regulation. The punishment of "red card" is closed and closed. (Wang Bin)
