During the "Eleventh Five-Year Plan" period, great achievements have been made in the construction and operation of urban sewage treatment facilities in China. By the end of 2010, 2,832 urban sewage treatment plants had been completed and put into operation, with a processing capacity of 12.5 billion cubic meters per day, an increase of 210% and 108% respectively compared with 2005. More than 90% of the city-set cities and more than 60% of the county towns have completed the construction of sewage treatment plants, and 16 provinces (municipalities and autonomous regions) have realized sewage treatment plants in counties and counties. The national urban sewage treatment rate has reached 77.4%, compared with 2005. The annual increase of 25 percentage points, the sewage treatment capacity exceeded the target of 10.5 billion cubic meters per day determined by the 11th Five-Year Plan.
The report of the National Urban Sewage Treatment and Recycling Facilities Construction Plan (2011~2015) released before the end of 2011 shows that the national key cities, prefecture-level cities, county-level cities, county towns, and established towns at the end of the "Twelfth Five-Year Plan" The sewage treatment rate reached 90%, 85%, 75%, 70%, and 30%, respectively. During the "Twelfth Five-Year Plan" period, the investment in sewage treatment facilities and sewage treatment pipe network reached 66 billion and 250 billion, respectively.
As the power equipment in the water treatment process, the pump plays the role of sewage lifting, transportation and pharmaceutical metering. The importance of the pump is self-evident. In some key aspects of the pump equipment, if there is a problem, it will lead the whole body. How to ensure the stable and reliable operation of the pump in the water treatment process, to play its "hero pump color", "General Machinery" magazine accumulated knowledge and influence in the water industry, as well as hosting the four international fan compressor forum and two pump peaks The forum's experience, in cooperation with the internationally renowned exhibition brand Hora Exhibition, was held in conjunction with the 5th Amsterdam International Water Treatment Exhibition China Exhibition (5th AQUATECH CHINA China), connecting users, manufacturers, design institutes, etc. The application of pumps in the production practice of the water industry.
