Description

technical field [0001] The invention relates to a composite water treatment agent, which belongs to the technical field of water treatment. Background technique [0002] Water is an indispensable natural resource for human production and life, and also an environmental resource on which organisms depend. With the intensification of the water resource crisis and the continuous deterioration of the water environment quality, the shortage of water resources has become one of the world's most concerned resource and environmental problems. one. Therefore, it is very important to save water, treat sewage, and develop new water sources, and vigorously developing water treatment methods will play a vital role in solving the technical problem of water shortage. [0003] There are many methods of water treatment, but the existing water treatment methods include physical treatment, chemical treatment and biological treatment. The physical treatment method is the simplest water treatm...
