[0002] Sewage treatment refers to the process of purifying sewage so that it meets the water quality requirements for discharge into a water body or reuse. Chlorine dioxide is often used in the disinfection step of sewage treatment processes due to its high disinfection and bactericidal properties and the lack of drug resistance.

[0003] In the existing chlorine dioxide disinfection machine for sewage treatment, the chlorine dioxide A solution and the chlorine dioxide B solution are usually directly added to the sewage through a pipe after the mixture is proportioned. However, the chlorine dioxide A solution and the chlorine dioxide B solution that are not mixed evenly will reduce the efficiency of disinfection and sterilization. Therefore, we propose a chlorine dioxide disinfection machine for sewage treatment. Utility Model Content

The chlorine dioxide A solution and the chlorine dioxide B solution are replenished into the solution tank A and the solution tank B through the two refilling valves. The provision of the two quick connectors facilitates the quick connection and separation of the external refilling pipeline and the two refilling valves.

[0009] Preferably, locking universal wheels are installed on the lower surface of the base near the four corners, and the base is moved and fixed by the four locking universal wheels.

[0010] Preferably, the dosing pump is a variable frequency pump, and a frequency converter is installed on one side of the upper surface of the base close to the solution tank A, and the frequency converter is used to adjust the operating frequency of the dosing pump according to the dosage of chlorine dioxide.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1.
