Description

technical field [0001] The invention relates to the technical field of sewage treatment, and relates to a sewage treatment device. Background technique [0002] Industrial production and residents’ daily life will produce a large amount of sewage. If the sewage is directly discharged into creeks and rivers without treatment, it will seriously affect the water quality and environmental landscape. A series of procedures such as alum and chlorination are finally discharged into the river. The traditional method used in China is to use liquid chlorine or take out the chlorine and mix it with water to dissolve the chlorine in the water to form a hypochlorous acid disinfectant, and then put a certain amount of hypochlorous acid into the bacteria-containing sewage through the delivery device to make it interact with the bacteria. In contact with each other, the strong oxidizing property of hypochlorous acid is used to kill bacteria and achieve the purpose of disinfection. At pres...
