Recently, the ecological edition of the People's Daily published an article titled "Fujian Sanming Jiangle County Upgrades Infrastructure and Improves Human Settlements - How to Make a Mountain County More Livable?" The report will actively promote the integration of rural domestic sewage collection and treatment, and use smart supervision and other means to solve problems such as operation and maintenance difficulties, and promote the obvious improvement of the rural ecological environment.
In recent years, Jiangle County, located in the western part of Fujian Province, has actively promoted the integration of rural domestic sewage collection and treatment, and used smart supervision and other means to solve problems such as operation and maintenance difficulties, upgrade infrastructure and improve the living environment.
In summer, Jinxi (Jiangle section) is rippling with blue waves, gentle wind, and the green hills on the shore are majestic and picturesque.
In the evening, smoke rises. In Xiang'an Community, Wan'an Town, Jiangle County, Sanming City, Fujian Province, after seeing off several customers, villager Li Ning closed his shop and went home to eat, walking briskly.
"Look at this sweat, wash it quickly." At the door of the house, Li Ning beckoned her daughter who was playing to wash her hands. In the bathroom, there are sinks and shower heads, and used water is discharged into the underground sewage pipe network through pipes.

Li Ning's new home is a small three-story building, and the inside and outside of the house are very clean. "We moved in the year before last, and now a family of six lives here, with a total of five bedrooms, each with a bathroom." Li Ning said that in the past, the water used for washing and cooking was often poured directly into the yard or poured into the ditch, and in summer, the front and back of the house were smelly and there were many mosquitoes.
In 2021, Jiangle County was shortlisted for the first batch of pilot counties for rural domestic sewage improvement and treatment at the Fujian provincial level. The local government has formulated the "County Rural Domestic Sewage Treatment Plan" and the "Five-Year Action Plan for Rural Domestic Sewage Improvement and Treatment in Jiangle County (2021-2025)" to accelerate the completion of the shortcomings of rural domestic sewage treatment and improve the rural living environment.
"According to the actual situation of terrain, population distribution and construction conditions, we have selected treatment methods such as 'takeover, centralization and decentralization' according to local conditions, and built sewage treatment plants and stations in 13 townships and 61 administrative villages in the county. Natural villages that really have no conditions also give priority to the selection of economical, low-energy, easy-to-maintain, and high-efficiency technical process equipment, and adopt new or renovated three-compartment septic tanks to treat domestic sewage, and make resource utilization of tailwater. Sha Chenlong, deputy county magistrate of Jiangle County, introduced that the local government has invested about 270 million yuan to build more than 100 sewage treatment facilities, with a daily treatment capacity of 8,000 tons and a supporting pipe network length of more than 210 kilometers.
"Now, all the domestic sewage is discharged through the pipeline, and the community has also carried out rain and sewage diversion transformation." Li Ning said that when the villagers built houses, drainage pipes were specially installed, and the village built a sewage pipe network buried deep underground, and the domestic sewage generated was discharged to the sewage station for treatment, "Everyone also consciously carried out greening and beautification, and the living environment is getting better and better!" ”

Install environmental protection facilities and discharge sewage up to standards
In Huangtan Village, Huangtan Town, the machine in the production workshop of Sanming Futan Agricultural Products Co., Ltd. roared. Pre-cooking, cooling, shelling, weighing...... After more than 10 processing processes, bamboo shoots are sold all over the country.
This company is the second fresh bamboo shoot processing company founded by Wu Yunfu. As early as 2017, Wu Yunfu co-founded a processing plant. "At that time, the wastewater from the processing was discharged directly." According to his recollection, because of the environmental pollution, the factory was ordered by the environmental protection department of Jiangle County to rectify the situation within a time limit: "At that time, the factory area was too small and there was no space to install sewage treatment equipment, so it had to be shut down first." ”
At the beginning of this year, optimistic about the development prospects of the industry, Wu Yunfu decided to return to his old business. "Under normal production conditions, we consume more than 150 tons of water every day, and produce about 50 tons of waste water and sewage." Wu Yunfu said that in order to ensure the orderly production, he invested 150,000 yuan to install environmental protection facilities to pretreat the sewage, "the factory has been discharged up to standard since it was put into operation, and can process more than 40 tons of fresh bamboo shoots every day, with an annual output value of about 5 million yuan." ”
Before it was put into production, Ge Jiahui, general manager of Yunjing Environmental Protection Technology (Fujian) Co., Ltd., was hired by Wu Yunfu as an environmental protection technician to provide technical support and consulting services for enterprises to treat wastewater. "By adding flocculants, the high-efficiency coagulation and sedimentation integrated equipment can biologically treat the sugar and cellulose in the wastewater, and at the same time quickly precipitate, separate impurities such as soil, and meet the discharge standards." Ge Jiahui said that the water quality is inspected once a week, and the environmental protection department conducts random inspections two to three times a month.
At the sewage discharge outlet, Wu Yunfu also installed grids and grids, and laid more than 100 meters of underground pipe network to connect with the Huangtan Town Sewage Treatment Station. On March 1 this year, Wu Yunfu signed a sewage takeover agreement with the Huangtan town government, stipulating that the pre-treated water quality should meet the third-level standard in the "Water Quality Standards for Sewage Discharge into Urban Sewers". Lin Shengsong, Secretary of the Party Committee of Huangtan Town, introduced that the town also carries out water quality monitoring from time to time, and if it is found that the tailwater is discharged beyond the standard, the new increase in the chemical and labor costs of the town's sewage treatment station will be borne by the enterprise, and will be handed over to the relevant departments for further treatment according to the excessive situation.
"For the quality of the sewage discharged after treatment, in addition to the testing of enterprises and environmental protection departments, we also hire a third party to conduct random inspections from time to time." Xu Shumin, deputy director of Jiangle County Ecological Environment Bureau, introduced.

Regular inspection and maintenance, and the construction of a smart supervision platform
The price of a set of water quality online monitoring equipment is about 100,000 yuan, and the installation of Jiangle County as planned needs to spend more than 10 million yuan, plus the operation and maintenance costs, which is a large expenditure.
In order to solve the problem of operation and supervision and effectively save operation and maintenance expenses, Jiangle County uses information technology such as the Internet of Things to build a smart supervision platform for rural domestic sewage, and carries out hierarchical and classified management of sewage treatment plants and stations in the county to ensure the continuous and effective operation of sewage treatment facilities.
At 8 o'clock in the morning, the golden pillar received a fault reminder text message. After receiving the notice, he and his colleague Wong Ka-shing immediately went to deal with it.
Huang Jinzhu is an O&M worker at Fujian Capital Jiajing Environmental Protection Technology Co., Ltd., responsible for maintaining sewage treatment facilities in rural areas in the southern part of Jiangle County. The two sewage treatment stations in Jiaohu Village, Nankou Town, are within his patrol range. Pointing to the schematic diagram of the pipe network on the fence, Huang Jinzhu said that the regulating tank is the first station to treat the sewage, then through the pump, the flow meter, and finally into the integrated treatment equipment.
Lifting the cement cover of the regulating tank, the golden pillar uses a scoop to stir back and forth in the sewage to filter the coarse residue, and then uses a brush to clean the grille. "It seems that it is the reason for the aging of the diaphragm of the air pump." Put down the chain, pull out the water pump, take a closer look, Jin Zhu explained, the water pump has been soaked in sewage for a long time, and the grease in the sewage will produce saponification reaction agglomeration after condensation, resulting in aging or failure of the diaphragm.
After replacing the diaphragm, the golden pillar continued to patrol along the sewage pipeline. "This is a data acquisition instrument, which is the 'brain' of the sewage treatment station, which can upload the operation status information of the equipment in the station in real time, and once a failure occurs, it will alarm and upload it to the county rural domestic sewage intelligent supervision platform." Huang Jinzhu said that from the actual situation, the fault is mostly caused by the failure of the meter sensor, and the rest should be disposed of on the spot as soon as possible.
In addition to the regular patrols of professional operation and maintenance personnel like Huang Jinzhu, the townships and towns of Jiangle County also arrange special personnel to manage and protect sewage treatment facilities. "The staff of the town environmental protection station inspects the sewage plant station with a daily treatment capacity of more than 20 tons once a month; For those less than 20 tons, once a quarter. Zhang Jieyu, member of the Party Committee and deputy mayor of Nankou Town, said.
Last year, Jinxi (Jiangle Duan) was selected as the second batch of excellent cases of beautiful rivers and lakes by the Ministry of Ecology and Environment. "Jiangle County will persistently promote the improvement of the rural living environment and transform ecological advantages into people's livelihood and well-being." Chen Xi, secretary of the Jiangle County Party Committee, said.
