Problems solved by technology

[0003] 1) Select the disinfectant generator according to the amount of sewage in the peak period. For example, how many grams of chlorine dioxide produced per hour are put into the sewage, then in the low peak period of sewage, the output of chlorine dioxide will not increase due to the reduction of sewage volume. Change, then the chlorine dioxide content in the sewage will inevitably exceed the standard, which will not only cause secondary pollution, but also bring about another problem: wasting chemicals and increasing operating costs
[0004] 2) If the disinfectant generator is selected according to the amount of sewage in the low peak period, such as how many grams of chlorine dioxide per hour are put into the sewage, then in the peak period of sewage, due to the increase in the amount of sewage, it is necessary to add the disinfectant dioxide If the amount of chlorine remains unchanged, the disinfection dose in the sewage must be insufficient to kill the bacteria and viruses in the sewage, resulting in the disinfection result failing to meet the requirements
Therefore, the use of disinfectant generators to disinfect hospital sewage is difficult to solve the problems of uneven hospital sewage flow and difficult control of dosing concentration.
[0005] 3) The chemical chlorine dioxide generator also consumes a lot of tap water, wastes resources, increases operating costs, and does not comply with my country's energy conservation and emission reduction policies. According to investigations, small medical institutions use chemical chlorine dioxide generators, and the natural gas consumed Come to the water may be more than the amount of sewage
The second type of situation: due to various reasons, the hospital sewage disinfection station does not have the ability to operate with a water level drop of 30 cm
[0010] According to the current standards, the existing hospital sewage treatment process is of low level, mainly due to the high concentration of suspended solids, which affects the disinfection effect; the water quality fluctuates greatly, and the dosage of disinfectant is difficult to control; the production of disinfection by-products is large, which affects the safety of the ecological environment; There is no upper limit for chlorine standards, and excessive chlorine will endanger ecological safety and other issues
