Problems solved by technology

Chinese patent CN1245149A adopts the method of directly separating tap water through nanofiltration membrane, and a large amount of impurities in the water can easily block the membrane pores, which greatly reduces the service life of nanofiltration membrane
Chinese patent CN2325096Y uses a pre-filter filter and an activated carbon filter to treat tap water in combination with nanofiltration. Since the broken particles in the activated carbon filter can easily enter the nanofiltration membrane module, the service life of the nanofiltration membrane will drop sharply.
In particular, the impurity content in high-salt tap water caused by seawater intrusion is much higher than that of ordinary tap water, and it is difficult to achieve the expected effect with ordinary nanofiltration

Abstract

The present invention relates to a desalting system equipment for running water with high salt content. Said desalting system equipment mainly includes active carbon adsorption filter tank, safety filter, ultrafiltration component, nano filtering component, clean water tank, pure water tank, ultrafiltration water supply pump, nano filtration water supply pump and various valves and pipelines.

Description

technical field [0001] The utility model relates to a high-salt tap water desalination system device, which is mainly used for the desalination treatment of high-salt tap water caused by backwashing of seawater, and belongs to the technical field of water treatment and its devices. Background technique [0002] At present, with the development of industry and agriculture in coastal areas, water consumption increases, and seawater intrusion has a tendency to expand year by year. Seawater intrusion led to a sharp increase in the salinity of tap water, directly causing drinking water difficulties for local residents. Seawater backflow is particularly serious in Chongming Island, Shanghai, my country's three major islands. Seawater intrusion directly causes the salinity of tap water in local waterworks to rise to 2500-3600mg / L (normally, the salt content is <150mg / L, and the highest can reach 5000mg / L. Therefore, it is necessary to solve the desalination of high-salt tap wat...
