Digital River Solutions

System Background

　　14th and 15th Five-Year Plan2035The annual long-term goal proposals suggest accelerating digital development: fostering the digital economy, advancing industrial digitalization and digital industrialization, promoting deep integration of the digital economy with the real economy, and creating digital industrial clusters with international competitiveness.

The Opinions of the General Office of the State Council on Improving the Compensation Mechanism for Ecological Protection state: Establish and improve the layout of key monitoring points for water quality and quantity in the important river basins and lakes across the country, as well as cross-province river sections, and develop an automated monitoring network. Formulate and perfect a monitoring and evaluation indicator system. Research and establish a statistical indicator system for ecological protection compensation and an information publication system.

Among the six key tasks of the River Chief System, it is proposed to strengthen the comprehensive improvement of river and reservoir water environments, promote the grid and informatization construction of water environment governance, and establish and improve the risk assessment and investigation, early warning and forecast, and response mechanisms for water environment.

Current Status of River Monitoring System

As people's environmental awareness grows, traditional surface water regulatory systems and remediation methods are no longer well-suited to meet development needs. Deficiencies in river pollution monitoring systems, coupled with the lag in emergency response after contamination, harm related river biotic communities; the lack of monitoring data leads to the absence of rigid constraint mechanisms and accountability and compensation clauses."Upstream pollution, downstream suffering" scenarios are playing out frequently; the imperfect monitoring system has led to the ineffective implementation of river chief systems in many areas, resulting in substandard water quality and environmental hygiene, causing tremendous losses to the people.

Notification on the Incident of Ineffectiveness in Implementing the River Chief System in Dongli District, Tianjin City:2017During the implementation of the River Chief System, Dongli District was summoned for discussion. Due to inadequate work guidance, coordination, and promotion, insufficient supervision and assessment, coupled with an imperfect monitoring system, the water quality and environmental sanitation at multiple locations were not effectively managed, resulting in substandard water quality and environmental sanitation issues.

These alarming cases prompt us to contemplate how we can update the existing river regulation and management systems, enhance the practical efficiency of river supervision, early warning, prevention, and governance, and keep a grip on changes in river water sources to promptly issue warnings for flood disasters, human-induced pollution, and other incidents.Sure.Minimize personnel and property losses to the greatest extent. In this context, Digital River emerged.

Digital Rivers can effectively address issues such as inaccurate river monitoring systems in various administrative regions, inconsistent water quality management goals, inadequate implementation of pollution control projects, and imperfect coordination management mechanisms. It provides support for improving cross-boundary river ecological compensation mechanisms, advancing overall water quality improvement in river basins, and constructing a civilization of water ecology.

Create a comprehensive digital river solution

The digital river solution developed by Derun Hou Tian Group is based onEco-friendly+Advanced concepts of the "Internet of Things" and "Big Data," with the principle of "deployment, networking, and early warning"; adhering to the principles of "issue-oriented, tailored solutions, and comprehensive prevention and control," we monitor water quality across large areas through reasonable deployment combinations, including river and lake sections, ports, and wharfs. We establish an integrated service system for improving surface water environmental quality, encompassing monitoring and supervision, emergency early warning, analysis and judgment, decision support, and comprehensive prevention and control. This forms a new pattern of environmental supervision with joint oversight.

Channel Flow Meter

Traditional surface water quality monitoring systems only focus on the changes in water quality, ignoring the importance of the river's flow parameters. Little do they know that without flow data, the perception of the river's characteristics is significantly compromised. Moreover, through the river flow parameters, one can also monitor water resources in real-time, acting as a weather vane for allocating water volumes in county and municipal basins and understanding the direction of wastewater flow. Particularly during sudden water pollution incidents, river flow data can provide crucial support for formulating measures to prevent the spread of pollution. Our company's independently developed river flow meter, utilizing the Doppler principle, boasts accurate measurement and easy installation among many other advantages.
