Description

Technical Field

[0001] This utility model relates to the technical field of domestic sewage treatment devices, and in particular to a reaction treatment device for domestic sewage. Background Technology

[0002] With the acceleration of urbanization, the discharge of domestic sewage has increased dramatically, and water pollution has become increasingly serious. Domestic sewage contains a large amount of organic matter, nitrogen, phosphorus, and other pollutants. If discharged directly without treatment, it will not only damage the aquatic environment but may also affect human health. Domestic sewage treatment technology mainly uses physical, chemical, and biological methods to remove harmful substances from the water to achieve water purification.

[0003] In wastewater treatment, a common approach is chemical treatment, where chemical agents react and remove pollutants from the water, often used to remove heavy metals, phosphorus, nitrogen, and other substances. Adding flocculants to wastewater can cause small particles to aggregate into larger flocs, facilitating separation and removal. However, the traditional method of directly pouring the flocculant into the reaction vessel often leads to uneven floc dispersion within the vessel, hindering sedimentation and resulting in poor treatment performance. Utility Model Content

[0004] The technical problem this invention aims to solve is that flocculants are prone to uneven dispersion during sewage treatment, which affects sewage treatment efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a reaction treatment device for domestic sewage, including a tank and a cover, wherein the top of the cover is connected to an inlet valve, the bottom of the tank is connected to an outlet valve, the top of the cover is fixedly connected to an insertion channel, and a drug injection component is fastened to the top of the cover, with one end of the drug injection component passing through the insertion channel and extending into the tank, the drug injection component including a rotating motor, and multiple drug storage tanks are sequentially fastened to the output end of the rotating motor.

[0006] As a further improvement of this utility model, the top of the medicine storage tank is provided with a groove, and the bottom is fixedly connected with a protrusion that is tightly engaged with the groove. Multiple medicine storage tanks are sequentially vertically engaged with the protrusion through the groove.

[0007] As a further improvement of this utility model, the bottom of the drug storage tank at the end of the drug injection component is fixedly provided with a backflow vane, and the backflow vane is located above the discharge valve.

[0008] As a further improvement of this utility model, four electromagnetic valves are fixedly installed around the bottom of the medicine storage tank.

[0009] As a further improvement of this utility model, a stirring motor is fixedly installed at the top of the cover, and the output rod of the stirring motor extends through into the tank body, and a stirring blade is fixedly installed on the output rod.

[0010] As a further improvement of this utility model, an assembly platform is fixedly provided on both sides of the insertion channel, and a snap-fit ​​post is fixedly provided on the top of the assembly platform. Ear plates matching the snap-fit ​​post are fixedly connected to both sides of the rotating motor.

[0011] The beneficial effects of this invention are as follows: This invention uses a multi-unit, modular design for dispensing flocculants. Flocculants are added at different liquid levels via electromagnetic valves on the bottom of the tanks, avoiding uneven flocculant dispersion at any single point during centralized dispensing. Furthermore, the inclusion of stirring motors on both sides of the dispensing assembly, with impellers at their outputs, ensures uniform flocculant dispersion, facilitating sedimentation and separation, and improving wastewater treatment efficiency.
