During the old national standard implementation, invisible relatively much less harmful substances. But then the standards now, it appears that some lag. Due to domestic and industrial wastewater pollution, water in many areas of organic compounds in water China, a substantial increase in ammonia and other pollutants, the so-called "micro-polluted source water," and regular "coagulation - sedimentation - filtration - sterilization" process, only removal of 20 to 35% of the organic matter, ammonia and other material for the removal of the effect is very limited. In addition, widespread adoption of water chlorination, studies show: After chlorination of water, triclosan, tetrachloromethane and other carcinogenic substances harmful to the integration of sewage treatment equipment, has more than 300 species. Social development today, and improve the quality of people's lives, for drinking water quality requirements are increasing life: drinking water not only to health, but also to the security; the public on water quality standards and international standards is increasing. Off-line chemical cleaning chemical cleaning at room temperature washing wastewater treatment equipment integration with a single agent, may not be fully restored membrane filtration performance sewage integration equipment manufacturers, but for a long time immersed membrane integration equipment in activated sludge mixture, Some highly resistant bacteria and microorganisms may be weak in some parts of membrane perturbation cumulative, easy to peel. Therefore, it is necessary to periodically clean the membrane module offline reinforced, in order to maximize recovery of the filtration performance of the membrane. Offline chemical cleaning, also known as immersion cleaning or chemically enhanced cleaning. And online chemical cleaning different chemical cleaning membrane system offline to run longer need to quit, and usually use a variety of agents, an appropriate increase in the cleaning solution temperature (about 35 ℃), high drug concentrations.
