Description

technical field [0001] The invention belongs to the field of sewage purification treatment, and in particular relates to a sewage purification equipment and a purification method based on chemical neutralization method and nanofiltration technology. Background technique [0002] The pollution control of water environment is one of the important strategic issues of global sustainable development. Especially in my country with a large population and lack of water resources, sewage treatment is particularly important. With the continuous increase of the number of cities and towns and the total population in our country, urban sewage treatment plants, as one of the important infrastructures, will develop rapidly with the process of urbanization, so our country will become a big country that uses water treatment equipment in the world . [0003] The widespread application and development of sewage treatment equipment in my country began in the early 1990s. With the rapid develo...
