Online Water Quality Monitoring System

1Online Water Quality Monitoring SystemBackground and Introduction:

The safety of secondary water supply and drinking water is an important basic condition for the sustainable development of modern cities. High quality and safe drinking water, as well as reliable supply, are the foundation for building a healthy society and promoting economic development. The water quality problem of drinking water in today's society has become an important factor restricting further economic development and affecting social stability.2012year7moon1Starting from [date], China will enforce the new version of the "Sanitary Standards for Drinking Water", with up to106According to the new national standard testing indicators, previously only the factory indicators were tested for tap water, but the new national standard requires that both terminal water and secondary water supply meet the standards. How to strengthen the monitoring of secondary water quality and provide safe water supply for residents is an urgent problem that needs to be solved in the current situation of lack of professional management, unsupervised pollution of secondary water supply, and unattended and over aged water supply facilities. according to2015year2The four ministries and commissions of the country jointly issued a notice on strengthening and improving the construction and management of secondary water supply facilities for urban residents to ensure water quality safety[2015]31Number),Online Water Quality Monitoring SystemThe operation and maintenance management of secondary water supply pumping stations for residents will become another key focus of future service management for water companies. Based on technological means, establish an automated remote monitoring and control management system for residential secondary water supply pump stations, implement patrol management for the main pump stations in some relatively closed water supply areas and all residential secondary water supply pump stations, establish a management mode combining remote monitoring and on-site inspection, and achieve remote monitoring of pump stations.

1.PH: Too lowPHValues can corrode water pipes, and excessive values can cause dissolved salts to precipitate, reducing the effectiveness of chlorination disinfection. Long term consumption at the same timePHToo low or too high water can also have a certain impact on human physiological health.

2.Residual chlorine: If there is no chlorine in the factory water or the amount of chlorine added is not enough, it may cause a large number of bacteria, Escherichia coli and other microorganisms to multiply in the pipeline network, affecting the water quality of the pipeline network. Therefore, a certain amount of residual chlorine must be ensured in the water supply pipeline network. So a certain amount of residual chlorine must be maintained in municipal tap water to ensure the safety of microbial indicators in drinking water. According to the hygiene standards for drinking water in China, chlorine comes into contact with water30After minutes, it should not be lower than0.3mg/LIn addition to the factory water that meets the above requirements, the water at the end of the centralized water supply network should not be less than0.05mg/L.

3.Turbidity: Turbidity is a crucial indicator for water quality. Reducing turbidity also lowers bacteria, Escherichia coli, viruses, Cryptosporidium, iron, manganese, and other contaminants in the water. Research has shown that when the turbidity of water is2.5NTUAt that time, the organic matter in the water was removed27.3%The turbidity has decreased to0.5NTUAt that time, the organic matter was removed79.6%The turbidity is0.1NTUAt that time, the vast majority of organic matter was removed, and the content of pathogenic microorganisms was greatly reduced. Especially for the water supply industry, turbidity indicators are crucial.

5Online Water Quality Monitoring SystemInstallation and debugging:

1.Equipment installation：

1.1 Environmental Requirements：The room where this equipment is installed and placed should be dry and well ventilated. It should not be installed in cold, damp, direct sunlight, or areas with a lot of sand and dust, and should not be installed in environments with chemical corrosion.

Ensure that there are no flammable, corrosive gases or conductive dust around this device during operation, otherwise it may cause some degree of damage.

1.2Installation location：The distance between the equipment and the outer wall of the room should be at least50cmThe heat dissipation distance and necessary maintenance distance.

1.3Power connection：The power supply for this device is single-phase AC power, with a voltage of220V±10%, frequency50Hz±1HzPlease connect the power cord that comes with the device to the on-site switchgear and ensure proper grounding. The power should be controlled by an air switch that meets the equipment's usage requirements.

2Debugging of equipment：

Before using the device, please connect the drainage water according to the installation diagramBecause there is no water in the pipeline, wait for the drainage water to flow out, ensure that there is no water leakage in the equipment, and then turn on the power.
