water station reporter Chen Jing taken
Lu network July 18th news on the one hand It is the sewage plant can not tolerate the running sewage at full capacity. On the other hand, many small water stations are built without use. Two contrasts, the provincial city every day there are about 100000 party sewage straight row of river into the Xiaoqing River. This can be seen that this year, the provincial capital should achieve the target of "the river can not see the smell of sewage and smell". It is necessary to make the scattered sewage treatment facilities run and reduce the pressure of the sewage disposal network and the sewage treatment plant. It is reported that the next step will be to promote the decentralized treatment of sewage sources through subsidies and other ways.
[load operation] 800 thousand tons of Nissan sewage treatment only 650 thousand tons
to intercept sewage and pollution control, first of all, we need to find out the amount of sewage produced in Ji'nan every day. Ji'nan Municipal Public Utilities Bureau in charge of the relevant departments, the total amount of urban sewage according to the daily water supply to calculate, "Ji'nan daily water supply of about 700 thousand tons, through the conversion rate of 0.8, about 600 thousand tons per day, and then add up to 20-30 tons of daily water from the well, not to calculate the next. The amount of sewage is about 800 thousand tons per day. " The person in charge introduced, in fact, the amount of sewage is higher than 800 thousand tons, especially in the summer, some of the pipeline rain pollution, rain is also a large block, in addition to the infiltration of groundwater, the construction of sewage produced by the impact of construction. For the four water purification plants, the average daily production of water is about 650 thousand tons. "In this way, even if the water purification plant is running at full capacity, there are still some parts of the sewage that are difficult to convert." The responsible person said that although high-tech zones and other water purification plants, but in comparison, it is still difficult to load.
[pipe network arrears] can not have long distance full collection of sewage
on the one hand, on the one hand, the lack of collection and transportation capacity of the pipe network also restricts the centralized treatment of sewage. The capital city is located in the South and the north is low. The sewage pipe can only be paved along the north-south direction, so the sewage treatment plant can only be built along the Xiaoqing River downstream.
in recent years, the three directions of the south, East and west of Ji'nan are expanding rapidly. A large amount of sewage is pouring into the existing pipe network, so that too much of the sewage pipe network that has been arrears is also hard to be concerned. Insiders told reporters that the current sewage pipe network in Ji'nan can not achieve full collection and full transportation of sewage.
sewage can not be collected, nor can it be processed. Where is the sewage? It is not difficult to find the answer from the smelly water of the river. Since the river courses in Ji'nan are basically north-south, they eventually flow into the Xiaoqing River.
[waste] part of the area in the water facilities "idle"
in fact, if the light depends on the centralized treatment of the sewage plant, it is doomed to not do the full treatment of sewage. But if the existing decentralized water stations are activated, the gap can also be filled. The reporter learned from the municipal department that by the end of 2012, there were 206 facilities in Ji'nan, 248 thousand cubic meters of sewage treatment capacity and 115 thousand cubic meters per day. Among them, there are 8 regional water facilities built by the Municipal Public Bureau, 5 water facilities built by the Garden Afforestation Bureau and 193 water facilities built by the society, and 93 of the water facilities in the community are built in the self built social water facilities. That being the case, why does the provincial capital still have about 100000 sides of sewage every day? Reporters interviewed learned that many communities of water treatment station utilization rate is not high, or even a lot of idle state. The head of the riverside group said, "the direct drainage of the sewage is one of the important sources of pollution. According to our investigation, at least 10 of the middle water stations in the residential area are at the idle stage. A large number of untreated sewage inflow into the Xiaoqing River directly, it is very terrible."
in the afternoon of July 16th, the reporter came to a high-end community near the Communist Youth League road. In the inconspicuous corner of the two floor parking lot, the reporter found the closed middle water room of the community gate. At the same time, reporters did not hear the sound of equipment running. After the discovery of the situation, the reporter came to the community's Property Management Company to inquire about the situation, but the property company's customer service personnel in the work of the Ministry of engineering is working on the grounds of rejection of the reporter.
and then the reporter came to dun Shun to become a community, and the water treatment facilities were not found in the community, and the residents did not know where the water station was. They had been warned by the relevant departments that the district had not opened the medium water equipment before.
[reckoning] the cost is too high to make part of the middle water station "build without"
why is the water station built, but would rather stop? The reporter has learned that the main problem is cost. "At present, the water treatment station in the city is capable of treating sewage on average from 3000 to 4000 cubic meters, and can even reach 5000 to 6000 cubic meters at the weekend. Because of the high degree of greening in the District, it is basically able to meet the demand for water inside the community." The song manager said to the reporter. The staff member Tian gave a careful introduction to the reporter that if the cost of equipment loss, labor cost and electricity fee were deducted, the cost of water per cubic meter per cubic meter was 1.5 yuan in the case of daily average treatment of more than 2000 cubic meters. In the case of 4.4 yuan / cubic meters higher than the greening water, the medium water used in the leading show was made. Cubic meters can save nearly 3 yuan.
but if the amount of treatment is not high, the cost of water treatment will be higher than the cost of tap water, and some communities will even be up to 5 yuan per cubic meter.
this, an insider of the municipal department, "the design standard of the medium water facilities in many large areas is designed according to the size of the community, the low standard, which will cause the high operation cost, which has caused its stranded to some extent."
[source interception] the provincial capital is expected to subsidize the social water station
according to the "Provisional Measures for the construction and management of water facilities in the city of Ji'nan", which is implemented in 2003, which should be built, expanded and rebuilt in the urban planning area. When supporting the construction of water facilities; building area of 20 thousand square meters or more of the residential areas must be supporting the construction of reclaimed water facilities.
however, the reality is that after the completion of the investment station, the water station is often "Shelved". How can these water stations turn to relieve the pressure of centralized sewage treatment? At present, Ji'nan has conducted research on this issue and will issue targeted policies.
before, the municipal departments had proposed that the water stations in these societies should be gradually integrated into the government's management and operation, but as of now, the reporters were interviewed, and the recovery and transformation of the water in this part had not been formally incorporated into the start of the agenda.
and in a reporter's interview, many water facilities management departments sent the same voice. "Since the recovery is very difficult, then the government can subsidize the water facilities and subsidize the water per cubic meter in order to encourage the operation of the idle medium water facilities." It is understood that the current policy is under investigation, and is expected to be implemented within the year.
in addition, municipal public utilities will further intensify the construction of Decentralized Reclaimed Water facilities. The middle water station of Zhongjing flood gully has been started and the water station of Chek Cabernet square is started in the near future, while other Dakai middle water stations, the international Zhonghai water station and the four Li Mountain medium water station are being pushed forward.
