Problems solved by technology

[0003] After long-term operation of the reverse osmosis device, colloids, metal oxides, bacteria, organic matter, scale and other substances will accumulate on the concentrated water side of the membrane, causing membrane fouling
The formation of membrane fouling leads to a decrease in flux and an increase in the pressure difference between the inlet and outlet of the module, which affects the economics of the reverse osmosis device
Membrane fouling is a common problem in the application process of reverse osmosis technology, and has become the biggest obstacle to the long-term stable operation of reverse osmosis systems

Abstract

The invention belongs to the technical field of detergents and particularly relates to a disk tubular reverse osmosis membrane alkaline detergent and a preparation method thereof. The invention aims to provide the disk tubular reverse osmosis membrane alkaline detergent which can remove dirt and blockage on a reverse osmosis membrane quickly and is high in practicality as well as the preparation method thereof. By adopting the technical scheme that the disk tubular reverse osmosis membrane alkaline detergent is prepared from 4.30% of 225DK, 4.00% of EDTA, 3.60% of NaOH and 88.00% of pure water, the disk tubular reverse osmosis membrane alkaline detergent provided by the invention is suitable for the field of sewage treatment.

Description

technical field [0001] The invention belongs to the technical field of cleaning agents, and in particular relates to a dish-type reverse osmosis membrane alkaline cleaning agent and a preparation method thereof. Background technique [0002] With the increasing shortage of water resources in our country, large-scale coal chemical enterprises have more sewage to be recycled. Reverse osmosis membranes can effectively desalinate, and are often used as a check process unit for water treatment to meet standards. They have been widely used in various fields such as seawater desalination, pure water preparation, boiler feed water, wastewater treatment, and concentration of drinking water, beverages, and chemical products. . [0003] After long-term operation of the reverse osmosis device, colloids, metal oxides, bacteria, organic matter, scale and other substances will accumulate on the concentrated water side of the membrane, causing membrane fouling. The formation of membrane f...
