Intelligent Guard, Source of Life
With the acceleration of industrialization and urbanization, sewage discharge has caused increasingly serious pollution to the water environment and water resources. Untreated or substandard treated industrial wastewater and domestic sewage contain a large number of harmful substances, such as heavy metals, chemical pollutants and pathogens. These substances not only destroy the balance of the water ecosystem, leading to eutrophication of water bodies and reduction of biodiversity, It threatens the safety of drinking water sources, hinders the sustainable development of agriculture, fisheries and industry, and increases the costs of social management and environmental restoration. Therefore, strengthening water pollution monitoring and prevention measures is of vital significance to ensuring water resource security, maintaining the ecological environment and social stability.
APPLICATION
01 Drainage water quality monitoring
The outlet is the direct channel for sewage to enter natural water bodies. Therefore, strict monitoring of water quality at the outlet is a key measure to control pollution sources and ensure the quality of downstream water bodies. Outlet monitoring usually targets point source discharges such as urban sewage treatment plants, industrial enterprise outfalls, and rainwater discharge outlets. Through regular or continuous monitoring, it is possible to ensure that the discharged water quality meets national or local standards, and to promptly detect and correct excessive discharges.
- Chemical oxygen demand (COD): an important indicator to measure the content of organic matter in water.
- Biochemical oxygen demand (BOD): reflects the amount of biodegradable organic matter in water.
- Ammonia nitrogen (NH₃-N): Evaluates the concentration of nitrogen compounds in water bodies. Excessive amounts can lead to eutrophication of water bodies.
- Total phosphorus (TP): Similar to ammonia nitrogen, excess phosphorus can also cause eutrophication of water bodies.
- Suspended solids (SS): Indicates undissolved solid matter in water, such as sediment, organic particles, etc.
- pH value: Measures the pH of water. Too high or too low will affect the survival of aquatic life.
- Dissolved Oxygen (DO): Essential for maintaining aquatic ecosystems, low DO can lead to fish kills.
02. Water quality monitoring upstream and downstream of rivers
Rivers are the main carriers of surface water, and the water quality conditions at different sections upstream and downstream directly reflect the pollution situation in the basin. The quality of upstream water determines the water safety of downstream areas; while the quality of downstream water comprehensively reflects the pollution load of the entire basin. Through long-term monitoring of multiple sections upstream and downstream of the river, the scope and degree of influence of pollution sources can be assessed, providing scientific basis for formulating reasonable water resources management and protection strategies.
- Conventional water quality parameters: including pH value, temperature, conductivity, dissolved oxygen (DO), turbidity, etc. These parameters can quickly understand the basic physical and chemical properties of the water body.
- Nutrient salts: such as ammonia nitrogen (NH₃-N), nitrate (NO₃), nitrite (NO₂), and total phosphorus (TP), used to assess the risk of eutrophication of water bodies.
- Organic pollutants: such as chemical oxygen demand (COD) and biochemical oxygen demand (BOD), used to evaluate the level of organic matter pollution.
03 Lake and reservoir water quality monitoring
Lakes and reservoirs are not only important freshwater reserves but also the main source of drinking water in many urban and rural areas. Because they are relatively closed, once contaminated, recovery is difficult. Therefore, long-term tracking and monitoring of the water quality of these water bodies is needed, with special attention to issues such as eutrophication and heavy metal pollution. In addition, water quality in lakes and reservoirs tends to change slowly, but when it deteriorates, it can have long-term impacts on ecosystems and human health.
- Nutrient salts: such as ammonia nitrogen (NH₃-N), nitrate (NO₃), nitrite (NO₂), and total phosphorus (TP), used to assess the risk of eutrophication of water bodies.
- Transparency: By measuring the transparency of a water body, the turbidity and algae count of the water body can be indirectly assessed.
- Dissolved Oxygen (DO): It is essential for maintaining aquatic ecosystems, especially during high temperatures in summer. Low dissolved oxygen may cause fish death. pH value: Measures the pH of water. Too high or too low will affect the survival of aquatic life.
- Organic pollutants: such as chemical oxygen demand (COD) and biochemical oxygen demand (BOD), used to evaluate the level of organic matter pollution.
04 Groundwater quality monitoring
As an important hidden water resource, groundwater plays an irreplaceable role in maintaining ecological balance and meeting human water needs. However, groundwater resources are susceptible to contamination from agricultural fertilizers, pesticide leakage, industrial wastewater leakage and other factors. Due to the slow renewal rate of groundwater, once it is contaminated, recovery is extremely difficult. Therefore, long-term monitoring of groundwater quality can provide early warning of potential pollution risks and protect this precious resource.
- Conventional water quality parameters: including pH value, conductivity, dissolution (DO), temperature, etc., used to evaluate the basic physical and chemical properties of groundwater.
- Nutrient salts: such as ammonia nitrogen (NH₃-N), nitrate (NO₃), nitrite (NO₂), and total phosphorus (TP), used to evaluate whether groundwater is polluted by agricultural non-point sources.
- Heavy metals: such as lead, mercury, cadmium, chromium, etc., especially for areas affected by industrial activities.
- Volatile organic compounds (VOCs): such as benzene, toluene, xylene, etc., often appear near petrochemical, electronic manufacturing and other industries.
- Semi-volatile organic compounds (SVOCs): Such as polycyclic aromatic hydrocarbons (PAHS), polychlorinated biphenyls (PCBs), etc. These substances are relatively stable in the environment and difficult to degrade.
Collection and transmission
In order to ensure the accuracy and real-time performance of water quality pollution monitoring, wireless water quality sensors need to be deployed. Mingkong uses high-precision sensors to measure water quality parameters (such as COD, BOD, ammonia nitrogen, total phosphorus, etc.) around the outlet or the upstream and downstream slopes of the river. (heavy metals, etc.), the equipment supports three Netcom 4G or NB communication methods to access monitoring data to the monitoring platform through 4G or NB wireless network, ensuring that the monitoring platform and mobile users can obtain accurate water quality information in a timely manner, for efficient management and provide a solid basis for decision-making.
