Detecção em tempo real de múltiplos parâmetros・Sensor de qualidade da água com alerta automático de anomalias e excedências

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 continuously increasing, and drinking water quality standards are also constantly developing and improving.

A norma para qualidade da água potável (GB5749-85), publicada em 1985, não atende mais às necessidades de proteção da saúde pública. Para isso, o Ministério da Saúde e a Administração Nacional de Normalização da China revisaram a norma original e emitiram conjuntamente a nova norma nacional obrigatória para qualidade da água potável (GB5749-2006).

IV.Overall

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

 

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

By comparing the data of raw water and effluent, it can be determined whether the purification facilities have 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: The turbidity value can guide the dosage of water purification agents and 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: monitors the metal ion content in water quality, effectively reflecting 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, with convenient integration. This instrument can be widely used for water quality testing in water plants, drinking water, tap water, mineral water, food, chemical, metallurgical, environmental protection, and pharmaceutical industries. It is a commonly used real-time online monitoring instrument.

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

The system belongs to our company's IoT environmental monitoring system products. It is an integrated software and hardware IoT solution independently developed by Shenzhen Yunchuan IoT Technology Co., Ltd. It is a real-time online monitoring system based on an environmental grid monitoring system, with data24-hour real-time reception, storage, download, chart display, intelligent analysis, intelligent alarm reminders, linked control of audible and visual alarms, and other functions. No software installation is required; management can be accessed through a browser. It has comprehensive coverage of data protocols such as HJ/T212-2017 and industrial control protocols, high system integration, rich functions, numerous tool sets, safety, reliability, and open compatibility. It is highly customizable and realizes the IoT water quality management model of "cloud management, automatic alarm, and remote viewing" for front-end equipment.

 

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 can provide 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 situations occur, preventive measures can be effectively taken in advance, advancing the early warning point of water quality safety incidents. At the same time, through monitoring the water quality of raw water and purified water, the production and processing process of drinking water can be effectively guided.
