Intelligent reverse osmosis multi-effect protection system

Abstract

The invention discloses an intelligent reverse osmosis multi-effect protection system, and the system comprises a shell and a control system; the interior of the shell is divided into an upper cavity and a lower cavity through a partition plate, wherein a large-flux precise filter element is arranged in the upper cavity, an ultraviolet lamp array is arranged in the lower cavity, an outlet of the water inlet pipeline is communicated with an inlet in the bottom of the lower cavity, and the top of the lower cavity is communicated with an inlet of the large-flux precise filter element through a through hole in the partition plate; an outlet in the side surface of the top of the upper cavity is communicated with the reverse osmosis system. According to the system, the probability of organic, inorganic and biological pollution of the reverse osmosis membrane is reduced to the greatest extent, the service life of the reverse osmosis membrane is prolonged, and the operation cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of water treatment and relates to an intelligent reverse osmosis multi-effect protection system. Background technique [0002] Reverse osmosis is a technology that uses the selective interception characteristics of semi-permeable membranes to efficiently separate the solute and solvent in the solution under a certain pressure. It is widely used in various industrial pure water, drinking water, semiconductors, pharmaceuticals and other industries. In recent years Since then, it has also begun to be widely used in the fields of circulating water sewage treatment, reclaimed water treatment, industrial wastewater treatment, and seawater desalination. The reverse osmosis membrane is susceptible to organic, inorganic and biological pollution during use, which seriously damages the membrane performance, resulting in a decrease in the desalination rate and water production rate of the entire system, and shortens the...

Problems solved by technology

However, no matter what kind of design, in the actual use process, it is impossible to ensure the complete removal of various pollutants, especially bacteria and microorganisms, which will breed and multiply in the filter element of the security filter and the reverse osmosis membrane, forming biological stickiness. Mud, leading to filter element and reverse osmosis membrane performance degradation, shortened service life

In addition, when the quality of raw water fluctuates, the performance of the front-end pretreatment system equipment declines, or the dosing control is improper, the reverse osmosis feedwater often has the problem of excessive organic matter (TOC). , further aggravating the degree of reverse osmosis biological pollution
