ABSTRACT:The water service is a significant industry in national welfare and the people's livelihood. With the quickening pace of people's living standard and the objective of achieving building a well-off society and enhancing productivity level, the water supply is increasingly demanded for the high quality. The computer automation control system of the waterworks is an effective measure for guaranteeing the high quality of the water supply in security and continuity. This article, which combines with the development tendency of the processing equipment intelligent and the reality of small and medium-sized water treatment plant in our country, has designed a water supply automatic control system by analyzing the reality of the waterworks automation control system both at home and abroad. This water supply automatic control system can in real time monitor the water quality, the water draw rate, the pH value, etc. Besides, the system can automatically add vitriol and throw chlorine; also, the system can auto save historical data. In addition, the system, in which there is an operation significance for reducing the gap with advanced standards, not only cuts down the energy consumption, saves cost, reduces the service maintenance working strength, enhances the management level, guarantees the water supply quality, but also improves the advancement of the water supply technology. The running conditions of the system reveal that its system function is complete; its performance is stable and reliable; there are strong practicability and promotion value.
