From May 28 to June 11 this year, the special supervision group on environmental protection of urban black and odorous water body in 2018, composed of the Ministry of Ecological Environment and the Ministry of Housing, Urban and Rural Construction, was stationed in Taiyuan to carry out special supervision.
5 months later, Taiyuan looked back. From Oct. 22 to Nov. 2, a special patrol for the treatment of black and odorous water in the city of 2018 was launched, and the 9th patrol team was stationed in Taiyuan again.
In recent days, the government knows that it has been following the inspection team in Taiyuan to patrol the river, and there are new problems emerging.
The black and stink section in the bush
The Xu Tan Drainage Channel mentioned in the video is on Taiyu Road in Taiyuan City. It intersects a branch of the East Trunk Channel and a North Zhang Drainage Channel and ends at the upper reaches of Xiaodianqiao and enters the Fenhe River.
In May this year, the inspection team found that although the Xutan Drainage Channel has basically eliminated the black odor, but the source control and pollution interception measures are not in place, there are still domestic sewage through the sewage outlet into the river. In July, according to local media reports in Shanxi Province, after a year of treatment, the water quality of Xutan drainage canal basically reached the standard. On the afternoon of October 26, the Ninth Inspection Group came to Xutan Drainage Channel again. The downstream river was full of water. There was no black and odor in the water. The sewage outlet found by the last inspection had been blocked.
However, the inspection team members have a new doubt.
Shanxi is an inland province. In the summer flood season, the discharge canal is abundant. But now it is autumn. The upper reaches of many rivers are almost dry. Why is there still a large amount of water in the lower reaches of Xutan drainage canal?
In order to find the water source, the patrol team followed the route of the drainage canal upstream, and found two confluences of different currents in a low bush area between Pingyang South Road and Xinghe Road, and between Xinghewan District and Guanghui District. One came from the eastern main canal, mainly the tail water treated by the upstream sewage treatment plant; the other belonged to the middle reaches of Xutan Drainage Channel, where an illegal sewage outlet was discharging domestic sewage.
This is a newly discovered black odor section. The inspection team said.
Connecting the East Main Channel with the Xutan Drainage Channel was a sluice. When the inspection team arrived, water from the East Main Channel was flowing through the sluice into the lower reaches of the Xutan Drainage Channel. An expert member of the inspection team to the North Qingbao reporter analysis, in the gate location, the East Main Channel flow is very large, black and smelly section of the water flow is very small, naturally formed a barrier to prevent the black and smelly water into the downstream.
Xu Tan drains the history of black and stink for at least 12 years.
In 2006, the river was already full of sewage; in 2011, the local environmental protection bureau monitored and identified serious pollution; in 2013, the implementation of sewage interception transformation; in 2015, the city management commission was listed as one of 19 built-up areas of black and stinky water.
From April 28 to May 28, 2017, the Second Environmental Protection Inspection Group of the Central Committee carried out environmental protection inspections in Shanxi Province. Xu Tan Drainage Channel was listed as one of the mass reaction problems assigned by the inspection group because of the sewage discharged and garbage dumped. The Discipline Inspection Committee of Taiyuan Wanbailin District also interviewed the Secretary of Houbeitun Community.
According to the announcement of the settlement of the problem, on April 4, 2017, the regulation scheme of Xutan flood drainage channel was approved and implemented, and the construction was planned to start in May, and the regulation was completed within the year. In May of the same year, the governor of Shanxi Province, the governor of the provincial general River and the Changlouyangsheng of the Fenhe River went to Taiyuan to investigate the ecological restoration and protection of the Fenhe River basin. He also took the local and relevant departments with him to investigate the sewage outlets of the Xutan Drainage Channel.
However, in addition to a newly discovered black and smelly section, according to public reports, the inspection team also found a collection of domestic sewage upstream Xutan Drainage Canal, about 1200 meters away from the black and smelly section of the dead water.
Well send someone to find out the reason and make rectification as soon as possible. The pumping, the interception of the interception! After discovering the new outfall and sewage in the Xu Tan drainage channel, the responsible person of the Taiyuan municipal management committee made such a stand. However, where the sewage came from, they failed to give a clear answer on the spot.
Members of the inspection team told the government that the remediation of black and stinky water must be a combination of root causes, not a simple plugging, source control is the key to find out the cause of pollution, in order to completely eradicate.
Zhang Bo, Director of the Department of Water Environment Management of the Ministry of Environment, once analyzed that the problem of black and stinky water is essentially a problem of sewage and garbage. The root cause is that the urban environmental infrastructure is not up to standard.
Zhang Qishan, deputy mayor of Taiyuan, has a deep understanding of this. Zhang Qishan said that one of the problems in Taiyuans treatment of black and odorous water body is that it is difficult to control the source, because many rain and sewage confluence pipelines are distributed in the old urban areas and industrial and mining enterprises gathering areas, with small diameter and early construction, and are relocated by neighboring households and demolitions. And traffic and other effects, the source control needs a certain process, some of the black and odorous water can only take interception, end of the interception and other measures.
Garbage dump still exists
However, the patrol team found that in the large Heishui River, the West Main Channel, chemical drainage channels and other rivers listed in the list of black and odorous waters, large areas of floating debris on the river surface and riparian garbage disposal problems still exist.
The West Trunk Canal spans the Wanbailin and Xiaodian districts of Taiyuan City, with a total length of 30 kilometers. In 2017, the river section included in the black and odorous water treatment task is 9 kilometers, of which about 8 kilometers have been covered, and in the 1 kilometer open channel, it is now full of garbage floating. On Hinghua West Street, besides garbage and animal carcasses, two bikes were parked on the banks of West Street in South Inner Rim, where River maintenance workers had salvaged them.
West trunk canal
The West Zhang village in the upper reaches of the big Heihe River is also a river with garbage problems after completion.
When the inspection team arrived in May, there were open rubbish dumps along the river, and there were rubbish floating in the river. Five months later, Zheng knew that the river had dried up, the bare bed of the river was marked by soaking boxes and plastic bags, the rivers open-air dumps were still there, and wild dogs were foraging.
Nevertheless, the garbage in the open air is cleared by garbage trucks every day, and white closed bins are placed on the roadside. Its only a dirty mess compared to the open rubbish dump. At noon, a forklift truck was cleaning up the rubbish dump. A villager came up with a trash can and dumped the rubbish into the dump, but turned a blind eye to the roadside bin.
By the end of the year, we will have completed the collection and transportation facilities of all river canals and ponds, made clear the location of refuse transshipment and disposal, ensured the timely collection and transportation of refuse, and put an end to the phenomenon of garbage dumping in river canals. At the start of the meeting, Zhang Qishan, vice mayor of Taiyuan, made a clear statement. The source of this article: political know editor: Wang Zheng _NN7526
