the part of the Daxin River in the province of the province. This year, the relevant departments of the provincial capital will also complete the renovation and reinforcement of the embankments of the old retaining walls, such as the industrial and commercial rivers, the Xingji River and the West Wei Zi trenches, and so on, to eliminate the hidden dangers. It sounds like an incredible proposition by journalist Liu Chang to take
to turn surface water into groundwater, completely clean up by natural ability, save money and save money. But starting this year, Ji'nan will implement a series of projects to artificially help surface water to leak to the ground and then extract it again. Soon after, the surface water that passes through the "gorgeous turn" will flow into the water pipes of the residents' homes in the identity of the groundwater, and the citizens will drink more of the high quality of the groundwater.

[idea change] once for Bao Quan to give up drinking water in the future not only to save water and to drink groundwater
for the Baotu Spring because of the city's crazy exploitation of groundwater for many years. Later, in order to protect the spring, Ji'nan sealed the vast majority of underground water mining wells. Up to now, in addition to some of the industrial needs of the underground water wells, Ji'nan has no permanent use of underground wells, part of the temporary reserve of water supply enterprises only reserved.
used to stop drinking water in the past because there was no effective source of supply, and it would take a long time to recharge the ground water once it was mined. Now, after the implementation of ground water conversion to groundwater, surface water will effectively supply the source of groundwater and can be used as a high quality groundwater for citizens to drink after "conversion of identity". In this way, the spring is formed and the people can fully enjoy the groundwater. "
" [multi survey] Ji'nan has delimited the "hatched" groundwater of the western the Yellow River strong seepage area in the west of the West. "The ground water in Israel and Singapore is used to convert ground water for drinking, which is the best way to optimize the water resources." Experts from relevant departments in Ji'nan appraised the plan of transforming surface water into groundwater.
according to the introduction, the geological characteristics of Ji'nan city are that there are more and more limestone near the southern mountainous area near the city proper, forming a good leakage area. In addition, the upper reaches of yuufu River, La Shan River, Xingji River, Daxin River, Shihe River (Han Canghe), Liu Gonghe, West Juye River, East Juye River and BA htung River have strong leakage function. There are about more than 20 strong seepage areas in the South and east of Ji'nan, which are the effective areas for the conversion of ground water to ground water. "The leakage of surface water and water to the underground, at the same time reducing evaporation, through the adsorption of different geological strata in the process of leakage, the natural purification of water, greatly shortening the distance of the supply and need for water, and the real pollution in the lower reaches, the upstream pollution in the strong leakage area is not outstanding. "Especially in this section of the Yellow River from Pingyin to Changqing, especially in the Yellow River, there is a huge leakage area, and the leakage area was found in earlier investigations that it was often saturated, that is, a large number of surface the Yellow River water could have been continuously purified, but the leakage area was full. The water can only go from the surface of the surface. Therefore, it is necessary to manually fetch water to make room for this "storage pool".
reporter learned that the water source of the two phase of the water supply project is located near the Cao Lou in Germany, which is located in the strong seepage area of the Yellow River. Therefore, it can be said that the two phase of the project itself is also a part of the ground water transfer project of the surface water in Ji'nan. "Natural purification and artificial extraction cost much less than surface reservoirs and water plants." The expert said, "in comparison, there is clay in the the Yellow River section of the Licheng section, which is not conducive to water leakage, while the groundwater in Zhangqiu is salty and is not drinkable."
[future objectives] the future groundwater will be the main surface water of water supply to be reserved for "standby"
"the proposed ground water conversion scheme and its project. It is to make a plan for the optimal allocation and utilization of water resources in Ji'nan, and to effectively protect and restore the leakage function of the existing groundwater recharge areas. A good relationship between the water supply and the conservation of the water. At the same time, it can also satisfy the aspirations of the public to drink groundwater, effectively reduce the cost of water supply and water supply, and improve the safety and protection capabilities of urban water supply. The director of Ji'nan municipal public utilities said, "the project is to make use of Ji'nan's unique hydrological and geological conditions and many strong leakage areas, the systematic optimization of the allocation of water resources, water reservoir, the Yellow River water, south water to the north water, sprayed spring water and the surrounding available water in Ji'nan." With the help of the high quality filtration and infiltration function of the earth soil layer, the soil is transformed into high quality groundwater after the filtration and infiltration of the soil. In this way, under the condition of keeping the spring water flowing well, the groundwater extraction facilities and the newly built groundwater drainage facilities are used to collect the groundwater for the residents' life.
this year, the specific project of this project will carry out the first phase of the yuufu Geopark, the first phase of the yuufu River in the upper reaches of the yuuhe River, and the project of the Xingji River and the East ditch of the square. At the same time, emergency standby water supply facilities to protect residents' normal life water should be completed. The in-situ surface water treatment system will be used as emergency (or standby) equipment in the future, and the two systems of groundwater and surface water will co-exist. The implementation of this system will synchronize the four goals of "good gushing of famous spring, drinking quality groundwater, reducing water supply cost and safe operation of urban water supply", which will play an important role in improving and improving the ecological environment of urban water, optimizing the basis and conditions of urban development and promoting the development of economy and society. "." The person in charge said.
> [leakage source] Ji'nan urban area will build 7 ecological landscape channel sections
while carrying out comprehensive river regulation, the Ji'nan Municipal Public Utilities Bureau plans to carry out the ecological river landscape upgrading project, and preliminarily selects the 7 ecological landscape channel sections in the urban Xingji River and the square east ditch.
the relevant person in charge of the Municipal Public Utilities Bureau introduced the function of building block and leakage through the upper river channel construction, fully blocking and utilizing the rain and flood, and scientifically invoking the water of Daming Lake and the surface water of the Jinxiu Sichuan reservoir, in order to transform the groundwater more, and to build the dam (sluice) in the middle and lower reaches of the river course. To create a city landscape and improve the ecological environment of water. The ecological river should reach the conditions of fish growth.
this year, the Bureau will use the good strong leakage capacity of the Xinghe river section on the north side of the second ring road to build the dam, and then the water of the reservoir of the supine Hushan Reservoir is introduced into the dam by self flow, and the water can be converted into the groundwater through leakage, while some excess water can make the downstream supplement the landscape. The Bureau will also use the standard water treated by the decentralized sewage treatment facilities as the landscape water for the non leaking section of the river in order to increase the water amount of the river and improve the landscape level of the river.
it is understood that river regulation will maintain its natural landscape, increase the number of green plants, improve the natural purification capacity of the river, and create a harmonious ecological landscape. On both sides of the river, while maintaining environmental hygiene, it will also become a place for leisure and entertainment for the public to stop and play.
[flood control] this year, it is a huge project to complete the upgrading of 20 water accumulating points in 2016 to upgrade 48 rivers and upgrade the city's flood control. It is a huge project, not only to control the river, but also to demolish buildings and obstacles in succession. From this year's river improvement work, we will strive to complete 48 upgrading projects for flood control, waterlogging and comprehensive utilization of rainwater and flood in 2016.
data show that the north and South height difference of Ji'nan city is 150 meters, and the capacity of the 65 rivers in the city from west to East is mostly less than 20 years, and the City mountain torrents seriously threaten the safety of the city. "Flood control work will set up a flood cutting ditch in the southern part of the urban area to improve the ability to block the mountain flood and alleviate the hazard of road flood. In the upper part of the urban area, a valley, a dam or a small under seepage reservoir will be set up in the upper part of the urban area. In accordance with the needs of flood control projects, the illegal and illegal buildings in the scope of the plan are dismantled according to the overall planning of the flood control project, and the obstacles of flood discharge are cleared, so that there is enough space for the treatment of the river. At the same time, we must continue dredging and dredging, and flood the bottleneck. According to the flood control planning section, we need to expand the river course, build river retaining wall, and solve the problem of insufficient flood discharge capacity. We should strengthen the construction of supporting facilities for river management, and install intelligent monitoring, warning signs, guardrails and lighting facilities. The staff of the Municipal Department said.
in addition, this year, the relevant departments will also complete the renovation and reinforcement of the old barrier river embankments, such as the industrial and commercial River, the Xingji River, the West Wei Zi trench and so on, to eliminate the hidden danger points, such as the consolidation and reinforcement of the old barrier river banks, and the construction of the guardrails. At the same time, 20 water collecting and collecting water facilities are completed for the problem of flood and water accumulation in the road. Some rain and sewage pipelines are rebuilt or newly built to improve the facilities of some pumping stations. Through the implementation of river interception, dredging, renovation, retaining wall repair, improve flood control and waterlogging capacity, bid farewell to light rain, water, heavy rain will be flooded.
