13 years of ground water, finally Back! Every day 100 thousand tons of underground water into the home, moisten thousands of citizens. Careful you, has the taste of a special sweet and friendly?
Baotu Spring continues to spray, the water level continues to climb, spring, people, prosperous, city Xing, Ji'nan presents a school of peace and charm. Careful you, whether the heart is filled with the happiness and glory of the spring city people?
this year flood season, Ji'nan, though repeatedly torrential rain patronage, but Enron spent the flood season, the city runs smoothly and orderly. Careful you, did you feel the confidence and the calmness of "human effort"?
to trace the root of the Ji'nan, the construction of the sponge city is outstanding. In particular, the city municipal public system has vigorously implemented the capacity construction of the sponge city. With the gradual completion of the three major projects, such as surface water to groundwater, water system supervision and flood control and emergency monitoring and warning, Ji'nan has synchronously realized "good gushing of famous spring, high quality groundwater for public drinking, reducing water supply cost and urban water supply safety." Full operation "four goals, the Ji'nan ecological water circle foundation is more firm, the city charm is further highlighted, the resource endowment and core competitiveness have been promoted," building four centers and building a modern spring city "have more momentum and strength.
this day, this newspaper has opened a column "focusing on the bright spot of the sponge city and visiting the front line" to show a series of results from the public and share the capacity construction of the sponge city with the public.
water system composed of surface water and groundwater is the "lifeline" of the city. At present, due to the limitations of development, the surface water and groundwater in many cities are isolated by "urban cement", and it is difficult to form an ecological cycle. "It will drown" and become "internal injury" in many cities. Ji'nan, which has been famous for its spring water, is not only the same, but also often faced with many problems of water resource utilization, such as spring water gushing, keeping the spring water unable to drink, and imperfect drainage facilities. The proposal of
sponge city concept provides a scientific solution for solving the water problems in a series of cities. Since Ji'nan became the first pilot city of the national sponge city construction in 2015, the municipal public utility system has fully promoted the three major projects of the capacity construction of the sponge City, mainly including the water supply hydraulic model projects serving the water supply and the groundwater drinking, and the research of the operational platform for the urban water system supervision and management of the water supply and drainage. And demonstration projects to ensure flood control emergency monitoring, early warning and emergency response system for urban flood control. Now, the three major projects have landed one after another, and the results of the project have begun to benefit the people. "Sweet Ji'nan, spring feast" has become worthy of the name. "Bao Quan" and "drinking spring", this once happy friends, now hand in hand became "relatives".
three line projects can be made up of 780 thousand tons and 41 Daming lakes to be deposited into the underground "water bank"
for the need of conservation spring, the citizens have been keeping the spring water for a long time and can only drink the purified the Yellow River water. How to make people drink better underground water without affecting the protection of springs or even help to maintain springs is a key issue to be solved in the construction of Ji'nan sponge city.
with the eagerly anticipation of all walks of life, with the help of the construction of the sponge City, the Municipal Public Service Bureau boldly innovating, learning from the advanced technology of Germany and Israel, starting the conversion of ground water to groundwater, transforming the water of the reservoir, the Yellow River water and rainwater into high quality groundwater, and synchronously realizing the "good gushing of the famous spring and the public drinking." We should use high-quality groundwater, reduce the cost of water supply and water supply, and ensure the safe operation of urban water supply.
after two years of hard work, surface water diversion to underground water works in East, central and West three lines. Now, the source project of the Yufu River in the west, the source project of the Liyang lake, the Xingji River in the middle and the first view of the Baotu Spring spring water, the main project of the supplement source project in the Daxin River in the East has all been put into operation, and the total supply capacity of the source reaches 780 thousand tons / day. According to statistics, with the aid of the Yufu River supplement, the middle line Liyang lake and the Xingji River, the groundwater recharge over 50 million tons in the last two years, which is equivalent to the water quantity of 41 Daming lakes. The
three line compensation project has raised the groundwater level, not only boosted the spring water, but also provided the public with the conditions for drinking high-quality groundwater.
in August 18th, the Municipal Public Utilities Bureau formally implemented the groundwater test and model adjustment work in Jixi City, and the scale of the test was 100 thousand tons / day. The groundwater is injected into the urban water supply network through the water intake unit, and the aspiration of the public to drink high-quality groundwater is finally realized.
the person in charge of the Municipal Public Utilities Bureau said that through the conversion of ground water to the underground water project, the city will use the existing multi-point layout of the groundwater extraction facilities and the new part of the groundwater intake facilities, and will be collected for the residents' life through multi point collection. The quality of underground water is excellent, the treatment process is simple, and there are many underground water points, so that the cost of water supply and water supply can be reduced without long-distance transportation through the pipeline network. Because of the large number of groundwater exploitation points, the dependence on the two major water plants has been reduced. After the completion of the project, Ji'nan will form two sets of urban water supply systems for surface water and underground water, and the safe operation of urban water supply will also be guaranteed.
sponge "heavenly eye" set up 10 sets of water safety "Skynet" system to quickly lock water pollution factor
with the increase of urban water consumption, the water quality safety of urban water system has become a new key point.
Municipal Public Utilities Bureau actively promotes the research and demonstration of water system supervision platform, focusing on monitoring the safety of urban water system. The project will further develop the monitoring capability of the central station of the urban water system, the capacity building of on-line monitoring, and the permeable sidewalk of the eastern section of the tourist road.
the capacity building of emergency resources support and the research on the evaluation system of the operation of the sponge City, to construct the traceability and risk assessment system of the characteristics of the urban water supply and drainage system, to realize the information collection and transmission of the multi source heterogeneous water system and the early warning and forecast for the emergency, in order to ensure the safe operation of the urban water system and the realization of the sponge City The overall goal provides a strong support.
at present, 10 automatic monitoring stations have been put into operation in 2 places, such as Liyang lake and Xingji River, which can realize the intelligent monitoring of more than 10 projects, such as turbidity, permanganate index, ammonia nitrogen and total phosphorus. In the event of pollution accidents, the pollution factors can be quickly tested and analyzed to determine the pollution.
43 monitoring points for flood prevention and emergency response to the flood season "flood devil"
experienced "8. 26" and "7. 18" heavy rain memory, the flood prevention and emergency response to Ji'nan is more important.
in the process of promoting the capacity building of sponge City, the Municipal Public Utilities Bureau has implemented the construction of flood emergency monitoring and early warning and emergency disposal system. In the 43 water monitoring and testing equipment, 31 stations have been installed and fully debugged. The application of information and standardization for emergency material management, the intelligent and integrated video monitoring and warning information, the scientific and standardized emergency command and dispatch, management decision and public information release, are used to do a good job in the construction of the sponge city. It will further improve the ability of comprehensive urban disaster prevention and mitigation, alleviate the pressure of urban water resources and improve the urban ecological environment.
sponge City three major capacity building projects have different functions, complement each other, complement each other and serve the sponge city evaluation. Among them, the groundwater supply hydraulic model can provide data support for the examination of the sponge City, the research project of the operational platform of water system supervision, the emergency monitoring and warning and emergency disposal system of flood control, and the monitoring and collection of water quality and water related data in the pilot area of the sponge city.
