China News Service, Jinan, September 18 (Sha Jianlong) Daily sewage is transported to the village sewage treatment station through pipelines, and is recycled after being professionally treated in Johkasou.

In the southern mountainous area of ​​Jinan City, the government-enterprise cooperation comprehensive sewage treatment project has solved the domestic sewage of nearly 10,000 villagers. It has improved the situation of cross-flowing and disorderly spilling of sewage on rural roads in the mountainous areas, and helped the protection and protection of local water sources. The rural environment is improved.

The relevant person in charge of the project introduced the sewage treatment technology.

  The mountainous area in southern Jinan is located in the remnant of Mount Tai, with beautiful scenery and fresh air. It has the function of purifying Jinan's "green lung". It is called the "back garden" and "living water source" of Jinan, and part of the area directly supplies the urban spring area.

Since Jinan proposed to further form a new urban development pattern of "Strong East, West Xing, South America, North China, and China Excellent", this area has attracted more social attention.

The villagers introduced the living habits and environmental changes of farmers after using sewage treatment equipment.

  Wang Chuanmei, a 74-year-old villager in the mountainous area of ​​southern Jinan, showed reporters the sewage pipelines in the kitchen and bathroom.

He said that before installation, households’ sewage was dumped at random. Some were poured into the yard and flowed into the alleys through drains, and some were poured directly on the gates. In summer, flies and mosquitoes breed and smell strong. In winter, yards and roads are easy to freeze. While affecting the lives of villagers, the ecological environment is also affected.

Now the villagers have formed a good habit of uniformly treating sewage. “The yard and alleys have no smell, and the ecological environment has become clean and hygienic.”

  According to on-site construction personnel, domestic sewage in northern China is rarely discharged out of the hospital through the pipe network. There are various drainage methods. In the past, the treatment ideas were mostly rain and sewage combined, and the effect was not ideal. If it rains, it will support it."

  Due to the lack of sewage treatment facilities in the mountainous rural areas of southern Jinan, the village sewage collection and treatment rate is relatively low. The sewage generated by the villagers’ production and life is discharged into rivers or streets without treatment, and after natural evaporation and infiltration, it will pollute the local surface water and groundwater. , Affecting the lives of residents, and destroying the regional ecological environment.

In order to solve this problem, the Southern Mountain Management Committee of Jinan City, based on the actual situation of local rural domestic sewage treatment, signed an agreement with CRRC Qiche Group Shandong Company, relying on CRRC’s technical advantages and brand resources to carry out rural domestic sewage treatment in the southern mountainous area. In-depth cooperation to improve the local rural human settlements and agricultural and rural pollution control levels, which not only benefits the people's livelihood but also protects the ecology.

  According to Li Pengliang, deputy general manager of the South Mountain Project Department of CRRC Shandong Company (Jinan), in 2020, the company will undertake rural domestic sewage treatment projects for 9,449 households in 38 administrative villages in the southern mountainous areas of Jinan, involving Zhonggong and Liubu streets. The installation of sewage collection pipelines and the construction of sewage treatment facilities for farmers in 38 administrative villages in 5 offices, including Xiying Sub-district, Jinxiuchuan, Gaoer, etc., is an important project for benefiting the people in Jinan.

  “Most of the villages here are built on the mountain. The terrain in the village is undulating, and the geological conditions are mostly rocky. The roads in the village are narrow, the residents are scattered, and the terrain is uneven. It is not easy to construct.” Li Pengliang said. There are generally sewage treatment plants in cities and rural areas. If you want to access, you need to overcome the distance problem, and the investment will be relatively large.

The comprehensive sewage treatment technology used by the company adopts biological treatment methods, adapts measures to local conditions, sets the number of stations and equipment processing capacity according to the size of the village, saves costs, and realizes unmanned control through the Internet of Things.

The treated water is used as circulating water for rockery, clean and odorless, meeting irrigation standards.

  At present, the comprehensive sewage treatment project in the southern mountainous area of ​​Jinan has been basically completed and has entered the final stage.

According to the relevant person in charge of CRRC Shandong Company, in recent years, the company has been committed to the research of sewage treatment system solutions in villages and towns by virtue of its advantages in advanced equipment manufacturing and industrialization in the field of rail transit. The whole-process ecological cycle has been applied on a large scale in Changshu, Jiangsu, Chongming District, Shanghai, Danling County, Sichuan, Jingjiang, Jiangsu and other places, and has been piloted and promoted in nearly 100 township sewage treatment projects in 28 provinces, municipalities and autonomous regions across the country, accumulatively serving farmers Nearly 300,000 households provide new ideas for solving the current comprehensive wastewater treatment problems in Chinese villages and towns.

  The comprehensive treatment of rural domestic sewage is only part of the "South American" strategy of pollution control in Jinan City.

Aiming at the ecological construction of the southern mountainous area, the southern mountainous area of ​​Jinan has been benchmarked to build "Five Jinan", with ecological priority and green development as the main line, creating an ecological, cultural, and healthy southern mountainous area, and promoting industrial projects, rural revitalization, urban construction and people's livelihood improvement .
