Abstract:

With the development of industry and technology, the need for freshwater increases day by day, the contradiction between the fresh water for production and livelihood is sharpened. An important way to solve the problem is desalinization of the groundwater. In this paper reverse osmosis disposal process of groundwater are used, PLC are used to control electromagnetic valves and water pumps in the desalinization water treatment system and automatic switching state or stop. Using touching screen as man-machine interface, which is more convenient for the operator to know the working stages, and is more facility for desalinization process. The system has many advantages, such a saving energy, high efficiency, more safety, control modes flexible and various, function extension easily. It has great significance in reduce cost of desalinization of groundwater and remission serious lack of the freshwater in some areas of China.
