Surface water monitoring system solutions

Program Overview

The Technical Regulations for Monitoring and Assessment of the Environment of Land-based Sewage Outlets into the Sea and Adjacent Sea Areas implements key monitoring, general monitoring and statistical monitoring according to the sewage discharge intensity of land-based sewage outlets into the sea, the environmental protection requirements of the marine functional zones in the adjacent sea areas, the degree of impact on the local society and environment, and the needs of marine management.

The “Emission Standards for Pollutants from Rivers Entering the Sea” (GB3097-1997) stipulates the emission limits for pollutants from rivers entering the sea, clarifies the monitoring indicators and frequency, and requires the establishment of monitoring stations at the mouths of key rivers to conduct regular water quality monitoring to ensure that emissions meet the standards;

“Opinions of the State Oceanic Administration on Promoting the Construction of Marine Ecological Environment Monitoring Network”: Marine ecological environment monitoring is the basis for marine ecological environment protection and supervision and management, and is an important support for the construction of marine ecological civilization. Strengthen supervisory monitoring of the marine environment, regularly conduct a census of land-based pollution sources entering the sea and marine pollution sources, and simultaneously carry out online monitoring in major rivers entering the sea and estuaries, key land-based sewage outlets entering the sea and adjacent sea areas. Build a supervisory monitoring system for the environment of marine functional areas, strengthen early warning environmental monitoring of agricultural and fishery areas, coastal tourism and leisure areas, etc., and implement full-process tracking and monitoring of the impact of marine dumping areas, offshore oil exploration and development areas, and marine engineering construction project sea areas on the marine ecological environment.

Shandong Dongrun’s online monitoring solution for the quality of water entering the sea from land-based sources is based on the fact that the country has continuously strengthened the protection of the marine water environment in recent years, the requirements for the supervision capabilities of marine management departments have been continuously improved, and the original manual monitoring methods are costly, time-consuming, and cannot reflect the current status of marine water quality in a timely manner. In response to the environmental conditions of nearshore waters, a monitoring system of “pollution source – river estuary – water quality and environmental quality” has been established to conduct online monitoring of the quality of water entering the sea from land-based sources.

Solution Features and Advantages

Based on different types of monitoring stations set up at the estuaries of rivers entering the sea that tolerate high salt and high humidity environments, with various small monitoring buoys and various aquaculture tailwater monitoring stations of aquaculture enterprises, with collection systems, water distribution and pretreatment systems, control systems and auxiliary units that are suitable for large salinity changes and many attached organisms, to achieve continuous real-time monitoring of the types of land-based pollutants entering the sea and various pollutants discharged into the sea
Multiple monitoring methods are available. Choosing the right monitoring station for different scenarios has cost and maintenance cost advantages.
This system uses advanced technology suitable for marine seawater monitoring, which is not affected by seawater salinity, and the accuracy of measured data is guaranteed. In addition, through the system monitoring management platform software and data model, comprehensive analysis and evaluation of land-based sewage discharge into the sea and business application can be achieved.
