TECHNICAL FIELD

[0001] The utility model relates to sewage treatment technical field, concretely is a kind of dosing device for rural sewage treatment. BACKGROUND

[0002] Rural domestic sewage is the main pollution source of rural water environmental pollution, and the pollution of water environment directly affects people's health and living environment, thereby restricting the development of local economy and affecting people's living standards. Therefore, sewage needs to be treated, and the current sewage treatment scheme has high energy consumption, poor module integration degree and high technical regulation degree. At the same time, due to the complex terrain in rural areas of China, different terrain and different site area greatly restrict the development and application of sewage technology.

[0003] At present, when the rural domestic sewage is treated, the sewage is transported to the collecting tank, and then the sewage treatment agent is added into the sewage to be treated at one time, and the agent is naturally dissolved and mixed with the sewage without external force. Then the sewage is pumped into the treatment tank by the liquid pump for treatment. However, this rural sewage treatment dosing method requires personnel to frequently add the agent, which increases the labor intensity of personnel. In order to facilitate the dosing in rural sewage treatment and reduce the number of manual dosing of personnel, we propose a dosing device for rural sewage treatment. UTILITY MODEL CONTENT

When the liquid pump pumps the bottom of the collecting tank, the water level of the collecting tank will drop. When the water level of the collecting tank drops, the height difference between the inlet pipe and the outlet pipe is formed, and then the mixed agent in the cylinder will be partially discharged by the outlet pipe under the action of the height difference, and the amount of the discharged mixed agent is the volume of the height difference between the inlet pipe and the outlet pipe. Therefore, the agent can be added. When the collecting tank is full, the agent can be added under the action of water pressure difference according to the above principle, so as to avoid the need for personnel to manually add the agent many times, effectively reduce the number of manual dosing of personnel, and solve the problem in the background.
