Construction of water quality online monitoring system: integrated multi-parameter detection + remote monitoring + abnormal alarm

I.Product background

Water is the source of life. Human beings cannot do without water in daily life and production activities. The quality of drinking water directly affects human health. With economic development and population growth, many regions face water shortages, and urban drinking water sources are often seriously polluted, threatening the safety of residents' drinking water. On the other hand, with scientific progress and the improvement of people's living standards, the requirements for drinking water quality and detection frequency are constantly increasing, and drinking water quality standards are also continuously developing and improving.

4. Overall

4.1 Selection of installation location for online monitoring equipment in tap water plants

 

The installation location should be selected upstream and downstream of the purification facilities, with monitoring at both the upstream and downstream of the purification equipment, and should be easily accessible, safe, with sufficient space, and convenient for operation;

By comparing the data of raw water and effluent, it can be determined whether the purification facility has failed.

4.2 Analysis of main monitoring factors

 

Raw water monitoring equipment:

• pH value: when raw water is chemically polluted, the pH value will change, thereby achieving early warning.
• Turbidity: turbidity value can guide the amount of water purification agent to be added, and can also reflect changes in raw water.
• Temperature: monitoring the temperature of raw water can effectively determine the conditions for adding water purification agents.

 

Effluent monitoring equipment:

• pH value: monitor whether the pH value indicator is within the national standard range.
• Turbidity: real-time monitoring of whether the turbidity of finished water is within the standard range, while guiding production and water treatment.
• Chlorine dioxide/residual chlorine: real-time monitoring of the residual amount of disinfectant in water, thereby guiding production.
• Conductivity: monitoring the content of metal ions in water quality can effectively reflect the content of heavy metals.

 

 

Product introduction

The system can be used to determineOzone, hardness, TDS, conductivity, residual chlorine, dissolved oxygen, pH, turbidity, ammonia nitrogen, nitrite, sulfate, phosphate, nitrate nitrogen, COD, sulfideand other water quality parameters. Users can select according to their needs, and integration is convenient. This instrument can be widely used for water quality detection in water plants, drinking water, tap water, mineral water, food, chemical, metallurgical, environmental protection, and pharmaceutical industries, and is a commonly used real-time online monitoring instrument.

The online detection system mainly includes a large-screen display system, terminal display and controller, various types of detection sensors, remote mobile terminals, and cloud data platform. It mainly detects various indicators of water bodies in the environment, as well as equipment that needs to be controlled, and can promptly alarm when abnormalities occur.

The system belongs to our company's IoT environmental monitoring system product, independently developed by Shenzhen Yunchuan IoT Technology Co., Ltd., an integrated software and hardware IoT solution; it is a real-time online monitoring system based on an environmental grid monitoring system, with 24-hour real-time data reception, storage, download, chart display, intelligent analysis, intelligent alarm reminders, and linked control of audible and visual alarms. No software installation is required; it can be accessed and managed through a browser. It features comprehensive data protocol coverage such as HJ/T212-2017 and industrial control protocols, high system integration, rich functionality, numerous tool sets, safety, reliability, and open compatibility, with high customizability, achieving an IoT water quality management model of "cloud management, automatic alarm, and remote viewing" for front-end devices.

 

Product advantages

Real-time online detection solutions are very convenient, allowing real-time measurement and real-time data transmission. Data can be viewed in real time on mobile phones and computers, analyzed promptly, and treatment plans provided, strengthening monitoring of various water source indicators. With specific detection data, it provides a basis for both effective prevention and efficient treatment, being both efficient and effective.

Through online monitoring of drinking water, the water quality situation can be dynamically understood in real time. When a situation occurs, preventive measures can be effectively taken in advance, advancing the early warning point of water quality safety accidents. At the same time, monitoring the water quality of raw water and purified water can effectively guide the production and processing process of drinking water.
