Abstract

The invention relates to a composite cleaning agent for cleaning a membrane system with organic fouling. The composite cleaning agent is prepared from the following components in percentage by mass: 15 percent of sodium carbonate, 25 percent of EDTA-4Na, 15 percent of sodium citrate, 1 percent of sodium dodecyl benzene sulfonate and 44 percent of pure water and the sodium carbonate, the EDTA-4Na,the sodium citrate, the sodium dodecyl benzene sulfonate and the pure water are subjected to chemical mixing at the normal temperature to form solution. The composite cleaning agent has the advantages that: through multiple effects, the composite cleaning agent removes the pollution of organic matter to the membrane system, can achieve good decontaminating effect, can solve the problem of harm ofvarious pollutants such as inorganic salt, metallic oxide and the like to the membrane system, has wide medicinal effect, can replace multiple medicaments for use, and has simple and convenient operation.

Description

technical field [0001] The invention relates to an alkaline composite cleaning agent for organic pollution such as oil, colloid, and surfactant in a water treatment membrane system, in particular to a composite cleaning agent for cleaning membrane systems containing organic fouling. Background technique [0002] With the continuous development of pure water technology and wastewater reuse technology, membrane technology (including reverse osmosis membrane, nanofiltration membrane, ultrafiltration membrane, microfiltration membrane) is more and more widely used in water treatment, while the water source is deteriorating Higher requirements are put forward for the normal operation of the membrane system, and the fouling of the membrane system has become the biggest obstacle to its operation. How to reduce fouling or how to effectively clean it after fouling are the two research directions that are most concerned in the industry. . The main types of pollutants in the membrane ...
