PLC Control for Automated Control System of Sewage Treatment Plant

With the construction of grid-based cities, online water quality monitoring systems have emerged as a solution. The Nantong Youteng online water quality monitoring system is a comprehensive online automatic monitoring system that takes online automatic analysis instruments as the core, and integrates modern sensing technology, automatic measurement technology, automatic control technology, computer application technology, as well as related special analysis software and communication networks. The online water quality monitoring system can detect abnormal changes in water quality as early as possible, provide early warnings quickly to prevent water pollution, and track pollution sources in a timely manner, so as to provide support for management decisions.

Application Scenarios:

1. Water quality monitoring of rivers, lakes and reservoirs

This system can be powered by mains electricity or solar energy. By deploying monitoring equipment on a large scale along rivers and lakes, and taking the Internet of Things technology as the carrier, as well as big data and cloud computing technologies, it provides a comprehensive water quality monitoring solution through the establishment of a system management platform.

2. Water quality monitoring of sewage treatment plants

This system can realize automatic sampling of enterprise wastewater and urban sewage, online monitoring of flow rate and online monitoring of main pollution factors; it can grasp the discharge situation of enterprise and urban sewage and the total amount of pollutant discharge in real time, and realize automatic transmission of monitoring data.

3. Water quality monitoring for aquaculture

This system can monitor multiple water quality parameters in real time for 24 hours, and query through terminals anytime and anywhere. It solves the breeding difficulties such as the inability to monitor water quality in real time and the difficulty of early warning of water quality parameter changes in aquaculture to the greatest extent.

4. Water quality monitoring of swimming pools

The water quality of swimming pools is directly related to human health, and unclean pool water will harm swimmers. This system can monitor the water quality of swimming pools in real time, helping pool users maintain the water quality of the pool.

Water Quality Monitoring Equipment:

1. Station-type water quality monitoring station:

The station-type water quality monitoring station is composed of a station house, an instrument analysis unit, a water intake unit, a water distribution unit, a control system, a data acquisition, processing and transmission system, an auxiliary system, a video monitoring unit, a power and environment monitoring unit, and lightning protection equipment, etc.

The instrument analysis unit includes a five-parameter analyzer (temperature, pH, dissolved oxygen, conductivity, turbidity), an ammonia nitrogen analyzer, etc.; the system is equipped with an intelligent environment monitoring unit to intelligently monitor the overall safety, fire protection and power distribution of the system. At the same time, the water quality automatic monitoring station is equipped with a video monitoring device, which can remotely monitor the status of the water intake and the interior of the station house in real time.

2. Floating water quality monitoring station

The floating water quality monitoring station (referred to as floating station) uses sensors placed in the river to monitor relevant data in the river, including pH value, conductivity, dissolved oxygen, residual chlorine, ammonia nitrogen, etc. These monitoring data help industry personnel to more comprehensively understand the current water quality status of the river, contribute to the formation of a sound long-term river management mechanism, and play a good role in supervising the effect of environmental governance.

The Nantong Youteng water quality monitoring system monitors water quality in real time, and can be used together with the Youteng Cloud Platform to jointly build a good water quality monitoring environment.
