1. Drinking water treatment generally involves purification, chlorination, and sometimes the addition of fluoridation agents. Treated water is collected by gravity or pumping into reservoirs and distributed through water towers or surface facilities. After use, the wastewater is typically discharged into the sewer system and treated at sewage treatment plants
（I）Membrane surface pollution and blockage 1. Organic pollution Cause: A large amount of organic matter contained in wastewater, such as protein, oil, polysaccharide, etc., is adsorbed and deposited on the membrane surface to form an organic film. These organic substances have strong adhesion and are easy to combine with microbial
