Problems solved by technology

After the multi-media filter runs for a period of time, the filter medium will be blocked by suspended debris
At present, the commonly used flushing method is to directly flush the multi-media filter with deep well raw water, which causes a lot of waste of deep well raw water and increases the amount of sewage discharge

Abstract

The invention aims at providing a water-desalting-station multi-media-filter washing water saving system. According to the technical scheme, the water-desalting-station multi-media-filter washing water saving system is composed of a deep pool, a water storage tank, a multi-media filter, a primary reverse osmosis part, a secondary reverse osmosis part, a mixed bed, a dry absorption circulating pool, a boiler, an acid refining device and a collecting pool. A water outlet of the water storage tank is communicated with a water injection opening and a washing opening of the multi-media filter through pipes, a water outlet of the multi-media filter is communicated with a water injection opening of the primary reverse osmosis part through a pipe, and a low-pressure-side outlet of the primary reverse osmosis part is communicated with a water injection opening of the secondary reverse osmosis part and the washing opening of the multi-media filter through pipes. The water-desalting-station multi-media-filter washing water saving system has the advantages that drained concentrated water is effectively reused, sewage draining is reduced while water is saved, and the good environment-friendly effect and the good economical effect are achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a water-saving system for flushing a multi-media filter in a desalinated water station. Background technique [0002] The raw water from the deep well is first filtered out by a multi-media filter to remove suspended solids and impurities, and then sent to reverse osmosis after being pressurized by a high-pressure pump. After the multi-media filter has been in operation for a period of time, the filter medium will be blocked by suspended debris. At present, the commonly used flushing method is to directly flush the multimedia filter with deep well raw water, which causes a lot of waste of deep well raw water and increases the sewage discharge. In order to solve the above problems, a water-saving system for flushing multimedia filters in desalinated water stations has been developed. Contents of the invention [0003] The object of the present invention is to provide ...
