[0021] The metering mechanism 3 includes a support column 301, a liquid tank 302, an infusion pipe 303, an electric control three-way valve 304, a liquid storage pipe 305, a liquid storage box 306, a liquid spraying pipe 307 and a liquid spraying plate 308. Two support columns 301 are fixedly installed on the top of the working tank 1, a liquid tank 302 is fixedly installed on the top of the two support columns 301, an infusion pipe 303 is fixedly installed at the bottom of the liquid tank 302, an electric control three-way valve 304 is fixedly installed at the bottom of the infusion pipe 303, a liquid storage pipe 305 is arranged on the left side of the electric control three-way valve 304, a liquid storage box 306 is fixedly connected to the left side of the liquid storage pipe 305, a liquid spraying pipe 307 is arranged at the bottom of the electric control three-way valve 304, and a liquid spraying plate 308 is fixedly installed at the bottom of the liquid spraying pipe 307. A controller 309 is fixedly installed on the front of the working tank 1.

[0022] In the case implementation, a motor 6 is fixedly installed on the back of the working tank 1, a stirring paddle 601 is arranged at the output end of the motor 6, the stirring paddle 601 is located inside the working tank 1, and a waterproof component is arranged at the output end of the motor 6. By arranging the stirring paddle 601, it can stir the sewage and disinfectant to be mixed, which helps to quickly disinfect the sewage.

[0023] In the case implementation, several spray pipes 7 are fixedly installed at the bottom of the liquid spraying plate 308. The several spray pipes 7 are evenly distributed at the bottom of the liquid spraying plate 308 fixedly installed in the middle. The diameter of the spray pipe 7 in the middle is smaller, and the diameter of the spray pipe 7 at the edge is larger.

[0024] In the case implementation, electromagnetic valves are provided outside both the water supply pipe 2 and the drain pipe 4. By providing two electromagnetic valves, the entry and discharge of sewage can be controlled to achieve quantitative disinfection treatment.

[0025] In the case implementation, a water level detector 5 is fixedly installed inside the working tank 1. By providing the water level detector 5, the water level of the sewage in the working tank 1 can be detected in a timely manner so as to close the water inlet in a timely manner.

[0026] In the case implementation, the controller 309 is electrically connected to all the electronic components in this patent through wires, so as to control all the electronic components in this patent by operating the controller 309.

[0027] During implementation, the following steps are performed for operation:

[0028] 1) When it is necessary to disinfect sewage, first turn on the controller 309, and then turn on the electromagnetic valve outside the water supply pipe 2, and the sewage is poured into the inside of the working tank 1;

[0029] 2) Then when the water level detector 5 detects that the water level reaches the highest water level, turn off the electromagnetic valve outside the water supply pipe 2, and then control the electric three-way valve 304 to open to connect the liquid delivery pipe 303 and the liquid storage pipe 305;

[0030] 3) Wait until the disinfectant in the liquid storage tank 302 enters the inside of the liquid storage box 306 and is filled up. The disinfectant stored in the liquid storage box 306 can disinfect all the sewage at the highest liquid level, that is, the liquid storage box 306 is filled with disinfectant, and the amount of this disinfectant is just enough to disinfect a box of sewage (the amount when the water level in the liquid storage tank 302 reaches the highest liquid level);

[0031] 4) Finally, control the electric three-way valve 304 to connect the liquid storage pipe 305 and the liquid spraying pipe 307, so that the disinfectant in the liquid storage box 306 enters the liquid spraying plate 308 and then flows into the sewage for disinfection through the spray pipe 7.

[0032] In summary, for the disinfection device for sewage treatment, by setting the metering mechanism 3, when it is necessary to disinfect the sewage, the controller 309 is turned on, and then the solenoid valve outside the water delivery pipe 2 is opened. The sewage is poured into the working tank 1. When the water level detector 5 detects that the water level reaches the highest level, the solenoid valve outside the water delivery pipe 2 is closed. Then, the electric control three-way valve 304 is controlled to open to connect the liquid infusion pipe 303 and the liquid storage pipe 305. Next, the electric control three-way valve 304 is controlled to connect the liquid storage pipe 305 with the liquid spraying pipe 307, so that the disinfectant in the liquid storage box 306 enters the liquid spraying plate 308 and then flows into the sewage for disinfection from the spray pipe 7. This metering mechanism 3 can reduce the use of parts, achieve quantitative proportioning as well, but at a lower cost, and the disinfection volume of the equipment with the same volume is more.
