Technical principle

Highly integrated multi-spectral online water quality rapid monitoring system adopts pioneered multiple optical spectral fusion analysis technology (MOSFA). The principle of MOSFA is based on ultra-violet and visible absorption spectra and multi-dimensional fluorescence emission spectra of water samples and builds a mathematical mode of water quality comprehensive indicators and water spectra, to derive a more comprehensive and accurate analysis of water quality by fully taking advantage of various spectrometry. MOSFA has significantly improved the capability of online analysis of water organic matter and other complex components.

Scope of application

1. "River Chief System", river, river network low-cost large-scale water quality monitoring system network.

2. "Lake Chief System", reservoirs, water sources, lakes low-cost large-scale water quality monitoring system network.

3. "14th Five-Year Plan " artificial intelligence, environmental monitoring network construction, online monitoring of pollution sources.

4. Smart cities, sponge cities, water-service cities, and other urban water network water quality monitoring.

5. Hydrology, agricultural irrigation areas, rural drinking water sources monitoring.

6. Process control of water quality monitoring during wastewater treatment.

Process flow and description

The highly integrated multi-spectral online water quality rapid monitoring system consists of a measurement subsystem (water quality monitoring station), a data acquisition and transmission subsystem, a platform, and other subsystems.

The measurement subsystem can be installed outdoors without the need to build a station, can test water quality on-site directly, and automatically monitor more than ten water quality indicators, such as chemical oxygen demand, permanganate index, ammonia nitrogen, total phosphorus, and dissolved oxygen. The system can be powered by solar energy. After data results come out, data is wireless transmitted through GPRS/3G/4G/5G, RTU, or CDMA to the server or the cloud, and the client can check and analyze the data in real time through the platform.

Promotion prospects

The highly integrated multi-spectral online water quality rapid monitoring system has many advantages including a wide range of measurement parameters, high measurement accuracy, short measurement time, no secondary pollution, low operating costs, low investment in equipment, and easy maintenance.

Meanwhile, its promotion and application can solve three major application problems of online water quality monitoring:

1) solve the installation problem of monitoring in the center of water bodies;

2) solve the problem that the traditional chemical station cannot access the water sample in real-time;

3) solve the problem of the high cost of application of online water quality monitoring system in a large scale; The application and promotion of this system have a significant social, economic and environmental benefits with great prospects.
