Description
Technical Field
The utility model relates to a device for disinfecting water plants by using sodium hypochlorite, belonging to the technical field of disinfection for water plants.
Background
The conventional disinfection process of the water plant adopts liquid chlorine disinfection, and the main advantages of the liquid chlorine disinfection are that the continuous disinfection effect of residual chlorine is achieved, the price is low, the operation is simple and convenient, and huge equipment is not needed. Chlorine is a yellow-green gas at normal temperature, has strong irritation and special odor, and has strong oxidizing ability. Under 6 and 7 atmospheric pressures, the chlorine can be changed into liquid chlorine, and the volume is reduced by 457 times. The liquid chlorine is filled into the steel cylinder, which is beneficial to storage and transportation. However, chlorine gas itself is toxic, and water disinfected by chlorine often produces a variety of harmful substances, especially disinfection by-products of "three-cause" action (carcinogenic, teratogenic, mutagenic), such as chloroform, chloroacetic acid, and the like. Meanwhile, chlorine has great harm influence on human body, and mainly invades into human body through respiratory tract and dissolves in water contained in mucous membrane to generate hypochlorous acid and hydrochloric acid, thus causing harmful influence on upper respiratory tract mucous membrane: hypochlorous acid can strongly oxidize tissues, and hydrochloric acid stimulates mucous membranes to generate inflammatory swelling, so that the mucous membranes of respiratory tracts are swollen, a large amount of mucus is secreted, the breathing is difficult, and people can generate severe cough. When the symptoms are severe, pulmonary edema can occur, making circulation difficult and leading to death. Chlorine gas entering the body from the esophagus can cause nausea, vomiting, chest pain and diarrhea. The maximum allowable chlorine content in 1L of air is 0.001mg, and the excessive chlorine content can cause human body poisoning. 3000mg/m3, it can paralyze respiratory center immediately and cause "flash death". Along with the development and expansion of construction, production units and residential houses are located around a water plant, the straight-line distance between the residential houses and a chlorine storage is less than 500 meters, and the hidden danger of using liquid chlorine is gradually highlighted.
