Sewage treatment pool feeding apparatus for water plants

Abstract

The invention discloses a sewage treatment pool feeding apparatus for water plants. The sewage treatment pool feeding apparatus comprises a feeding pipe, wherein a mixing cavity is arranged in the feeding pipe, the left portion and the right portion of the mixing cavity are communicated to each other, and the mixing cavity is slidably connected to fixing devices symmetrically arranged left and right. According to the present invention, the structure similar to the triangular chuck is used to fix the pipes with different diameters so as to enhance the use range of the equipment; the self-adjustable closed ring is formed through the limitation of the spring and the sling groove so as to ensure the sealing property at the interface of the equipment; according to the impart force on the waterflow, the faster the water flow, the faster the stirring; the amount of the agent taken out of the agent box every time is a constant value, and only the number of the opening per unit time is increased, such that the proportion of the total feeding is increased; and by using the principle of centrifugation, the faster the rotation, the larger the injection volume per unit time, such that the workefficiency of the treatment is ensured.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a dosing device for a sewage treatment pool used in a waterworks. Background technique [0002] A common dosing method in sewage treatment plants is to determine the dosing ratio of sodium hypochlorite through a small test, and the operator calculates the corresponding dosing amount of sodium hypochlorite based on the average water inflow for several hours, and adjusts the flow rate of the sodium hypochlorite dosing pump. Due to manual adjustment, it is difficult to accurately control the dosage of sodium hypochlorite, which often results in insufficient dosage of chemicals to affect the quality of effluent water, or excessive dosage of chemicals is wasted, and if the dosage of sodium hypochlorite is too large, it will cause effluent and chlorine The other is to preset the dosing ratio in the control system, but the water intake of the sewage plant varies greatly, and er...

AI Technical Summary

Problems solved by technology

Due to manual adjustment, it is difficult to accurately control the dosage of sodium hypochlorite, which often results in insufficient dosage of chemicals to affect the quality of effluent water, or excessive dosage of chemicals is wasted, and if the dosage of sodium hypochlorite is too large, it will cause effluent and chlorine Higher, which will affect the environment of the discharged water body. The other is to preset the dosing ratio in the control system, but the water intake of the sewage plant varies greatly, and errors are prone to occur. A device that can solve the above problems is explained in the present invention.
