The Design of Filter Pool Automatic
Control System in Waterworks based on PLC
Water plant water supply is essential for people As the modern urban society and economic development urban water consumption continued to increase water supply insufficient has become the bottleneck of the urban development the use of groundwater resources is nearly saturated increasing the supply of surface water is the only feasible way to solve the problem of inadequate water supply Water supply not only to meet the needs of the pipe network to ensure adequate water supply but also significantly improve the water quality Therefore the critical process of the water plant upgrade to improve its water treatment capacity increasing the amount of water is an effective way to meet the needs of urban development The filter is the last of the waterworks net structure of the conventional treatment process the filter is running a direct impact on water quality of the water treatment plant
The goal of this thesis is a systematic approach to solving water supply automatic control filter backwash process the continued use of artificial means labor-intensive low efficiency security is difficult to protect and this must be the transformation of the filter automation systems
In this paper the following work A detailed analysis and synthesis of the history of the development the type of automation system and water supply enterprise automation of water supply enterprise automation application status A brief introduction on the water plant filters process Filter the liquid level control and backwash control and control strategies are analyzedPLC har
