Integration of Yangtze River water into Ji'nan's water ecological construction and multi-point detection to ensure water quality
recently, the Ji'nan Water Transfer Project of the East Route of the south to North Water Transfer Project - the East Lake reservoir water transfer project was formally started construction. The project is expected to be completed in 2017, which will bring 40 million 500 thousand cubic meters of water for the city every year. The contradiction between supply and demand of water in eastern part of our city can be basically solved. Before this, the Yangtze River water has entered the yuhushan reservoir and began to fill the Yufu river. After the next step of the reconstruction of the water supply line of the yuhushan reservoir, the southern area of the city will begin to drink the Changjiang River.
after the arrival of the Yangtze River water, the water resources allocation pattern of Changjiang water, the Yellow River water, ground water, surface water and unconventional water "five water co-ordinate spring city" has been realized. The quality of the water ecosystem of the river and lake wetland water ecosystem has been improved, the standard rate of water function area is obviously improved, and the consciousness of water conservation and protection in the whole society is constant. Enhance。 The arrival of the A Changjiang River does not affect the price of irrigation and living water for the time being
because the water supply channel of the yuhushan reservoir is damaged by the dumping of waste, and the water supply of the southern suburb water plant is stopped, and the water supply of the city has been suspended for nearly 4 years. On the basis of the connection between the Jinxiu Sichuan reservoir and the Hsin long reservoir in December 25, 2015, the reporter was informed that all pipelines and tunnels and channels in the water supply line of the reservoir were completed in December 25, 2015. It was introduced that the original Nankang pumping station was demolished, a pump station was rebuilt at the original site, and the damaged water pipeline was repaired at the original site, and the water supply to the southern suburb of the reservoir was restored. The pumping capacity of the new pumping station will reach 150 thousand cubic meters per day, of which 100 thousand cubic meters are supplied to the southern suburb waterworks by the pretreatment plant. The other 50 thousand parties are sent to the Jinxiu Chuan reservoir through the water conveyance pipeline to supply water to the watershed water works.
water from the Jiangdu pumping station in Yangzhou, Jiangsu, water, and 1467 kilometers from the water pump station along the road to spring city. Therefore, the construction cost of the south to North Water Diversion main line project is high. According to the relevant policies of the national development and Reform Commission, the price of water supply in the early period of the south to North Water Transfer Project is priced by the zoning section, according to the "two system" system. The mode is divided into basic water price and measured water price. Among them, the basic water price is determined according to the principle of reasonable repayment of the principal and interest of the loan and the appropriate compensation for the basic operation and maintenance costs of the project. The water price is determined according to the principle of other costs and expenses, such as pumping electricity, material fees and so on, other than the basic water price. According to the reporter, at this stage, the provincial government levied the water price of South to north water transfer to our city for 0.82 yuan per cubic meter, 0.83 yuan per cubic meter of water price and 1.65 yuan per cubic meter of water price. At present, the water of the Yangtze River is mainly used for water resource allocation and ecological water use. In the short term, it will not affect the price of irrigation and living water. In the next step, the city will accelerate the reform of regional comprehensive water price, and ensure the use of the long river water. B city ecological water replenishment function has been realized
after the Spring Festival this year, our city started 2015 - 2016 to adjust the Changjiang Water passenger work. Up to now, the Changjiang River has been adjusted to 20 million cubic meters. In the water transfer period, 300 thousand cubic meters of water from the Yangtze River, through the three level water pumping station of the Yufu Hushan Reservoir in the south to North Water Transfer Project, climbed up the 29.6 km water pipeline and continued to flow into the reservoir of the supine tiger mountain. The historic step of the Hushan Reservoir has realized the "three water source" guarantee of the Changjiang River guest water, the Yellow River water passenger and surface runoff. It is an important measure to practice the new water treatment idea of "water storage, reservoir water and spring water conservation". It provides a reliable water source support for "building four centers and building a modern spring city".
because of the main use of the Yellow River water as the main water source for living water at present, the main water supply of the Yangtze River is to replenish the source of the Yufu river reservoir at the present stage, and to supplement the source of recharge to the strong leakage zone of Yufu River, and to supplement the water supply to the Yuqing lake and other reservoirs according to the actual water requirement. Not long ago, the water pump unit of the Nankang pump station and the hulon pump station of the water supply line renovation project of the yuhushan reservoir was started, and the water from the Changjiang River was successfully entered into the hulon reservoir through the Yufu river water diversion project of Yufu River and the five storehouse connected project. The reporter learned that after the completion of the reconstruction of the water supply line of the reservoir of the reservoir, the water diversion source of two leakage zones in Shaw and Zhun village and Daojian gully had been started. The water diversion from the Xing Long reservoir was successful, which not only increased the source point of the leaking zone of the Hushan earth house, but also marked the benefit of the five reservoir connected projects in ensuring the ecological water use in the city. The initial display. The water transfer project of the C East Lake reservoir is expected to be completed next year
as a continuation project of the Ji'nan city of the East Route of the South-North Water Diversion Project, and the water conveyance project of the East Lake reservoir is also an important part of the construction of the water ecological civilization of Ji'nan. At present, the daily water demand of the eastern Ji'nan city is 670 thousand cubic meters, and the public water supply capacity gap is 420 thousand cubic meters. In the eastern part of the eastern part of the city from 2014 to 2015, "water shortage" appeared in the eastern part of the residential area. According to the responsible person of the Municipal Water Conservancy Bureau, with the continuous expansion of the urban scale, the water supply gap in the eastern part of the city will be further aggravated, and the problem of water shortage will be solved.
according to the reporter, the water conveyance project of East Lake reservoir can further optimize the allocation of water resources in the urban area and improve the support ability of urban water supply. The East Lake reservoir water conveyance project is planned to lay a pipeline of 21 kilometers long, and design water supply capacity of 300 thousand cubic meters per day. The estimated investment will be 270 million yuan, and the project will be completed in 2017. At present, the project has started construction. After completion, it can supply 40 million 500 thousand cubic meters of water to the urban area of Ji'nan every year, and effectively improve the water supply guarantee rate in our city. D real-time detection guarantees the water quality of the Yangtze River
the east line of the south to North Water Transfer Project in Jiangsu, which mainly relies on water transportation pipeline in the territory of Shandong, while entering the territory of Shandong, the Grande Canale and Nansi Lake, Dongping lake and other lakes are fully utilized, but the projects along the project are low-lying, there are many rivers, only the South four lake basin, and 31 thousand and 700 square kilometers of flow. Within the scope of the area, it takes 53 rivers to come in. The special physical and geographical conditions determine the task of pollution control in the south to North Water Transfer Project is very arduous. The reporter learned that, before the construction of the construction in 2002 to the official opening of the water in 2013, 7 billion 516 million yuan of the provincial capital raising funds in Shandong Province was invested in the work of pollution control along the Shandong section. 93 sewage treatment plants and 53 garbage disposal plants have been built along the line, and the daily processing capacity reached 4 million 90 thousand tons and 22 thousand tons respectively. In addition, 21 new sewage diversion projects have been built along the Shandong section, which can "digest" 2.06 million tons of water each year, reduce COD by nearly 50 thousand tons, and increase the effective irrigation area of 2 million mu of farmland. With the implementation of the diversion and diversion project of the medium water, the original river and low-lying land within the scope of the project have been built into a wetland system, which has increased biodiversity, melts environmental protection, flood control and water storage and other functions as a whole, improves the local production and living environment conditions, and improves the ecological environment quality within the scope of the project.
in order to make the water diversion work well to ensure the safe and smooth entry of water from the Yangtze River, the actual situation of the related reservoirs and other water diversion plans is fully considered, and the annual water diversion plan is carefully prepared and reported. According to the requirements of the municipal water supply leading group, many units, such as the municipal water supply and drainage testing center, have been sampled and tested on the Yangtze River for many times and many points, all of which have reached the standard and meet the requirements of the entry. The water quality will be checked at any time to ensure the safety of reservoir storage. E in order to make Ji'nan citizens familiar with the project content of South to North Water Diversion Project and understand the construction progress and operation status of the south to North Water Transfer Project in our city, the city south water north transfer Bureau was actively plotting and completed the Ji'nan city south to North Water Diversion Project Exhibition Hall at the beginning of this year and declared the approval. "Ji'nan popular science education base" has become another new window for the propaganda work of the south to North Water Diversion Work in our city.
the exhibition hall is located at the Wenshan pumping station of the Hushan Reservoir Water Transfer Project of Yufu River, which consists of two parts: the outdoor engineering facilities exhibition area and the indoor exhibition hall. The exhibition area of outdoor engineering facilities has three levels of water lifting platform. The exhibition hall is displayed in the form of comprehensive exhibition, model production, electronic equipment and multimedia system integration through the construction materials and facilities, such as pipe fittings, valves, etc. The construction layout, the introduction of the supporting engineering, the benefit of the engineering, the builder's demeanor, the relocation of the harmonious sign, the quality management, the high quality engineering, the scientific and technological innovation, the cultural construction and the civilized construction site are made up of 25 components, and the whole course of the construction of the south to North Water Transfer Project in our city is systematically and comprehensively presented.
