Reporter squatting 丨 Lvshui farmhouse around, watching rural water control
2022-08-07: [Article Link] There are clearly fewer mosquitoes in the village than before, and Liu Shihuah, a villager in the town of Liu Dingdong, Qi Ha County, found the reason for the construction of four “wells” outside the new courtyard wall.
These four wells are actually not wells, but four drums of integrated sewage treatment.
"When the water pump in the fourth well covers is pumped out, it can be poured directly. Each household has a clean drain, no stink, less flies and mosquitoes, and the village is clean." Liu Sheila told the reporter.
The health of the water ecosystems of the Yellow River basin is directly linked to the management of sewage and black and stinky water bodies in rural areas, as well as to the “colouring” of ecological protection and quality development of the Yellow River basin in our province. Journalists have visited various parts of the province to actively promote the management of sewage and black and stinky bodies in rural areas and to change the “diversion of sewage from evaporation”. Find a way out of the sewers.
In the area between Qingjiang River and Lake Maga, Boheing County, the belt is spread across nine villages, including the villages of Siem Rei, Fujia and Mao, where the terrain is particularly high and the village is located in the middle of the rise zone, and on the south side of the lake and on the north side of the small Qing River is low. “Water flows downwards. For these villages in the past, sewage flows in two directions, either to the northern slopes into the small el-Qing river, or to the southern slopes into the Lake Judas. Rural sewage is mainly washing, ablution and some sanitation; compared to a well-developed system for sewage management in urban areas, it is the most traditional way of treating all types of sewage in rural areas at a very late start. “There are no industrial projects in the vicinity of Lake Judas, and if we can hold the mouths of rural sewage and black and stench bodies, the water quality of the River Kiyo and Lake Judas is largely guaranteed.” Wang Litao told journalists. The sources of pollution are clear, and then the rest of it is dry - to find a way to find the way to the village's sewage.
In 2020, construction began on the south-east corner of the village of Mao's village in the village of rural sewage disposal on the northern shore of the Lake.
Journalists have observed that the treatment station is connected to the sewage pipes of the villages and is connected to the wetlands. “The sewage from the nearby villages is concentrated in the treatment station through the pipes and the treated water reaches the surface water category five. After further purification of the wetland belt, three or four types of water flow into the small river.” Liu Kai, Deputy Chief of the Land Sequestration Unit, Bureau of Eco-Environmental Affairs, Rim State, said. With the completion of the operation of the sewage treatment station in June last year, more than 14,700 people living in nine surrounding villages were effectively collected and managed, changing the history of dirty water pouring around surrounding villages, “sewages are evaporated” and the return of the Lake to clean and green. Centralized treatment of sewage such as this is not the only option for sewage management in rural areas, and it is a major challenge for rural residents to live in dispersed settlements and to build collection networks at a higher cost. The Programme of Action for the Environmental Protection of Rural Rural Areas, “14th Five-Yar Plan”, in Shandong Province, provides for the selection of local solutions for sewage management in rural areas. Areas located on the outskirts of towns, with access to pipelines and relative concentration of residence, give priority to intensive treatment near urban sewage networks; areas with large populations, high concentrations, high levels of sewage generation and relatively favourable economic conditions, may be considered for central treatment of sewage treatment stations; areas with relatively small concentrations of sewage generation but capable of generating run-off of sewage can be treated in a centralized collection mode; and non-ecologically sensitive areas with fewer populations, dispersed settlements or more complex topography, combining the environmentally sound disposal and resourceization of toilet excreta with simple approaches to governance based on decentralized treatment. Natural bases, geographical characteristics, economic conditions and folklore vary from place to place, and diversified sewage treatment patterns are emerging. “It is proposed to select 15-20 counties (municipalities and districts) throughout the province to promote integrated models of sewage management in rural areas, management of rural black and stinky water bodies, rehabilitation of rural centralized drinking water sources, integrated use of straw, clean disposal of rural waste, and the use of animal waste and waste resources. The nazi can also flow two types of water.
“There are now two main sources of water — the Yuzu River and the Yu Qing Lake — in the shadowy area of the city of Jinan. “Before 2020, there is a third `source' — living sewage in surrounding villages. In the past, with the pace of industrialization, urbanization, the influx of industrial and domestic effluents, the continuing deterioration of the water quality of the small river, which continues to be the worst five categories, the desire to make the “small river” a good one, and the reality of the “small black river” as the pace of industrialization and urbanization accelerates.
“If you want clean water, the source must first be fixed.” Lee Jia-jin said that the shaded area had focused in previous years on the management of rural sewage in 15 villages at the source of the small river. “We find that this is not enough. There is still a large gap between the rural wastewater emission target, level B, and the cut-off test, three types of water. In the case of COD (Chemical Oxygen), the COD concentration in level I B can reach 100 mg/L, but the COD requirement for the three types of water is 20 mg/L and therefore continues to be treated. During the past two years, the shaded areas have been overhauling the sewage system in rural areas, particularly in the villages of origin, where it has been completely overhauled — all of which have been cut off and the sewage has been treated centrally through the pipeline into the Great Light Sewerage Treatment Plant. How effective can it be to cure the sewage from rural livelihoods? Real-time monitoring data for July 27, at 10 a.m., show that the water quality is two types of water on the side of the small Qing River.
From the cut-off to the river, in 2021, the water quality of the mini-ching river was met for the first time by three types of surface water standards. In the first half of this year, the water quality of the sub-ching river reached a record level of surface water II. It's used as a treasure.
Fragmentation increases the difficulty of sewage management in rural areas, but the greater characteristics of rural agricultural land, gardens, forest land, etc. also provide a broad picture of the reuse of water resources.
"How do we use them again? Outside the south wall of Liu's small courtyard, Wang Junjian, the chief chairman of Zhao's town, opened four wells in turn, and the water beneath the well was gradually cleared from the first well to the fourth well. “The kitchen, the water table, the toilet are connected, and all the dirty water is connected to the integration equipment through the pipe. Sewage is collected in turn through drums, anaerobic drums, aerobic drums, clean water drums, treated with microdynamics and fungic reinforcements for excreta and then treated to the secondary standards of rural living sewage treatment at the point of clean-up. This is the model of “better latrines + integrated domestic sewage” driven by the whole county of Qi River County: “From construction to operation, farmers do not take money. Sewage treatment equipment is procured centrally in the counties, with a subsidy of $1,000 per household for damage to the ground, etc. At the time of construction, the village unit was resubsidised at the township level. Rural environmental capacity and self-purification are larger than urban capacity and, in the case of total pollutant discharges and intensities, rural-living sewage can be used directly after sound treatment, for example for irrigation of agricultural land, greening of gardens, etc., and, after further treatment, for landscape and ecological rehydration. “This amounts to the installation of a “micro-life sewage treatment plant” for each household, which is not wasteful of treated water and can be edible, which becomes a treasure. In March of this year, 13 departments of our province jointly issued the 14th Five-Year Plan Action Programme for the Environmental Protection of Rural Rural Areas in Shandong Province, which identified the basic completion of rural wastewater management in key functional areas such as the Yellow River Stream, the Greater Bong River Basin and the South Lake Four Basin by 2023, the completion of environmental rehabilitation in 16,700 additional administrative villages by 2025, a 55 per cent rate of sewage management in rural areas, and the virtual elimination of black and stinky water bodies in rural areas. Journalists have learned from the Provincial Department of Ecology that since 2021 my province has completed the task of treating sewage from living in 4,000 administrative villages. “The next step is to explore in depth ways to optimize sewage from living in rural areas, guided by the promotion of the use of domestic sewage resources.
