Chinanews.com (Chinanews.com) chinanews.com, Yuncheng, January 3(Fan Shuqi) do you believe it? Sewage also has“Fingerprints”, which can be used by environmental law enforcement officials to find sewage companies. Recently, “A clear river flows into the Yellow River -- an expert media on the ecology of the Fen River River Basin” conducted a research in Jishan, Shanxi province, the device, which can be used to identify the “Fingerprints” of sewage, was seen in a Industrial wastewater treatment project in Jishan County's Zhai Dian Industrial District. The 'fingerprint' of sewage is used to identify the Industrial wastewater treatment of the enterprise, the Zhai Dian Industrial Complex in Jishan County Province, which was designated by the Shanxi Provincial Government in 2022 as a key provincial-level water pollution prevention and control project in the Fen River River basin, it is also a key project for the 2023“A clear river flows into the Yellow River”. The project is located 1,000 metres north of Beiwu village, Zhai Dian Town, Jishan County Province (within the living Sewage Treatment of Zhai Dian Town, Jishan County) , the construction sewage treatment scale is 4000 M3/D.

“The most important feature of this sewage treatment project is that each company's sewage can be 'fingerprinted' by various indicators of sewage discharge,” said Li Hongwu, head of the Jishan branch of the Yuncheng Ecological and Environmental Bureau, who described the system in detail. The system can project the fluorescence intensity of the water sample on the plane with the excitation and emission wavelengths as horizontal and vertical coordinates in the form of contour lines, and can obtain three-dimensional fluorescence spectra, each fluorescent substance has its own three-dimensional fluorescence spectrum. The three-dimensional fluorescence spectra of water samples vary with the types and contents of pollutants, and have the characteristics of one-to-one correspondence with the source of pollution, so it is called water quality fingerprint. The fingerprint of wastewater quality is significantly different from that of unpolluted water, which can be used to judge whether the water is polluted or not The water quality fingerprint of different enterprises in the same industry often has obvious difference, so we can identify the pollution source by the water quality fingerprint ratio.

After an in-depth understanding of the system, member of the expert panel, Udege people, said that the automatic monitoring station for water pollution warning and traceability for the project fully applies the technology of water quality fingerprint pollution traceability, to promote the ecological environment law enforcement work from“Civil air defense first” to“Technical air defense first”, weave a dense water quality automatic monitoring network, and build a precise, scientific and standardized automatic monitoring system, we will comprehensively improve the scientific, accurate and law-based treatment of water pollution in the Fen River River basin. Jishan's contribution to “A river of clean water flowing into the Yellow River” since the Industrial wastewater treatment project in the industrial cluster of Zhai Dian started 2023 in October, the water quality standards for the national examination section (Chacun Bridge) have improved significantly. In October, the water quality standards for the section (Chacun Bridge) have reached Class III, and in November, the water quality standards for the section (Chacun Bridge) of the national examination in Fen River Province have reached Class II. The water quality standards for the section (Chacun Bridge) of the national examination have been fulfilled ahead of schedule, and the water quality standards for the section (Chacun Bridge) of the national examination section (Chacun Bridge) have reached Class III in June. This is a concentrated reflection of the achievements of Jishan County's 'one clear river flows into the Yellow River' initiative,” said Nan Xuanzhi, a member of the Standing Committee of the Jishan County Party Committee and Deputy Head of the county. According to the briefing, Jishan County has included a total of 12 projects, including eight provincial projects and four municipal projects.

So far, four projects have been completed, including the Industrial wastewater treatment project in the Zhai Dian Industrial Cluster, the XISHE industrial park wastewater centralized treatment project, the XISHE industrial park wastewater centralized treatment project, and the Jishan wetland vegetation restoration project. The five projects under construction are the Fen River River Basin Jishan River Section Comprehensive Management Project, which has completed 70% of the total project volume, the Fen River River Jishan River section flood control capacity improvement project, which has completed 63% of the total project volume; Construction of the 2023 diversion and subsequent source treatment project in Jishan County started in December, and the first phase of the rural sewage treatment project has already completed 70% of the total 2023, the 2024 project is expected to be completed in June, while the construction team of the Jishan section of the Fen River River has entered the construction site and is expected to be completed in December 2025. The three projects that have yet to start are the Jishan Economic and Technological Development Zones reclaimed water reuse project, which is expected to start construction in April, and the Fen River River basin (Jishan section) sewage treatment works tail water artificial wetland water quality purification project, construction of the 2024 is expected to start in April, and the construction of automatic water quality stations and data services for key sections of the Fen River River basin is in early planning.

In the 2024, Jishan County will strengthen supervision and dispatch, make all-out efforts to advance project progress, prepare project construction funds through multiple channels, and establish and improve management systems and inspection mechanisms, regular supervision and on-site supervision of the progress of operational projects and projects, contributing Jishan's efforts to “A clear river flows into the Yellow River”.
