Shanxi Datong "Yellow River To Datong" Water Supply Project Water Treament Plant Processes Design And Research

With economic growth and population growth and the improvement of living standard, Datong existing water supply facilities, water and urban water supply can not meet the requirements of urban water demand. "Water crisis" has restricted the Datong an important factor in national economic development. To this end, through the relevant departments and experts argued that the "economic with the Yellow River" project as complete a fundamental way to solve water shortage in Datong City."Yellow River to Datong" works include waterworks engineering, quality testing and control center, distribution network and compression station project. Particularly in the water treatment plant process design and construction as the top priority, because its success or failure is directly related to urban drinking water hygiene in Datong, relate to people's lives and security, involving the vital interests of every household, the livelihood plans.The issue of" Yellow River to Datong " project, water treatment plant design and actual water quality monitoring data for the original design in order to "drinking water health standards" (GB5749-2006) for the treatment process to achieve the standard, refer to the current domestic Water run similar successful experiences and comparative analysis of the process advantages and disadvantages of different technology, research and design a set for "economy with the Yellow River" project waterworks treatment process, and can effectively guide, used in water purification plant project late construction. Contents and methods include:1. Analysis of "economic with the Yellow River" project after the implementation of water treatment plant, water loads;2. According to "drinking water health standards" (GB5749-2006) requirements related to water quality standards, drawing national existing successful experience in building water works, waterworks Zishen light of water quality characteristics of different processes by the comparative analysis and demonstration to design an appropriate treatment process at the factory, and given the treatment process design parameters.After the program was discussed, on the treatment process water purification plant, decided to use " Chemical pretreament+Strengthen conventional processing+Seasonal powder activated carbon(PAC) adding " of the process, and according to technology selection, design a more complete design of the various processes parameters. In addition, the design of the water in the process of production of the most sensitive anti-generated waste water washing process gives a more sophisticated treatment processes to ensure that environmental requirements.
