[China Instrument Network Instrument R&D] Do you remember the shocking 170,000 square meters of industrial wastewater seepage? The red wastewater is comparable to strong acid. In fact, where we can't see it, industrial spitting and super-distribution may occur every day. occur.
Self-developed by Tsinghua University, Tsinghua Holdings member company, Chenan Technology, conducts water pollution early warning and tracing instrument for achievement transformation and marketing, assists environmental supervision departments to realize surgical source precise control, and is the national ecological environment monitoring network construction and water security protection. Provide solid technical support.
Recently, Shenzhen Municipal Human Settlements Environment Committee installed a dyeing and water pollution warning tracer at the No. 6 outfall of the Jiangbi Industrial Zone to monitor the water quality abnormally for many times, indicating that the company has exceeded the standard for discharging industrial wastewater. Through comparison of water quality fingerprinting, the fingerprint characteristics of the Jin* electroplating factory in the industrial zone are obvious. The minimum similarity is 82%, and the highest is 100%. There is a significant risk of pollution. The environmental monitoring and monitoring departments jointly conducted surprise inspections on the company. After sampling and analysis, there were four pollutants exceeding the standards, of which total phosphorus exceeded the allowable emission concentration by 11.7 times.
Wang Weixiong, deputy director of Shenzhen Municipal Human Settlement Committee, led the municipal environmental monitoring detachment, the environmental monitoring center station, the person in charge of the Bao’an District Environmental Water Bureau, and related staff. He inspected and implemented the “Chunlei Action†related work plan in Jiangbi Industrial Park and checked the action on site. In the investigation, the Yongxing Electroplating Company suspected of laying underground pipes for evacuation of industrial wastewater and the enforcement of the gold electroplating factory suspected of exceeding the standard of direct industrial wastewater that were locked out by law enforcement officers through water quality fingerprint warning traceability technology. After listening to reports from the municipal and district environmental protection agencies on the work situation and law enforcement effectiveness after the initiation of the “Chunlei Actionâ€, Wang Weixiong made instructions on the next phase of work and asked “We must strengthen the enforcement of science and technology, and carefully summarize the preliminary use of water quality fingerprint warnings. Based on the successful experiences and practices of new types of law enforcement tools such as traceability tracer, water balancer, automatic sampler, on-line monitoring, and video surveillance, we actively use scientific and technological means to achieve accurate enforcement of environmental pollution violations.â€
The water pollution warning early-warning technology that was used to accurately combat the illegal discharge of pollutants was independently developed by Tsinghua University, and was transformed and marketed at Chen An Technology. It has been applied in many regions across the country. This technology won the Special Commendation Award for the Jury of the 45th Geneva International Invention Fair in 2017.
The early warning technology of water pollution can help the environmental supervision and other related departments to comprehensively and in real time grasp the information related to water pollution and the comparison results, and at a glance, realize the early detection, rapid processing, and proper handling of abnormal water quality events. The technology can identify major sources of pollution and pollution migration pathways, identify the key points for governance and management, and responsible parties, and promote the formation of surgical sources that can be precisely managed to form long-term mechanisms to maintain the effectiveness of water environment governance.
