Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a dosing device for wastewater treatment. Background Technology

[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. A common method of wastewater treatment is to add a treatment liquid to a wastewater storage tank. The treatment liquid reacts with the substances in the wastewater, causing the wastewater to flocculate, settle, and separate into layers, thereby achieving the purpose of treating the wastewater. Although the wastewater treatment dosing devices currently in use can meet normal usage requirements, they still have defects in actual use.

[0003] For example, the wastewater treatment dosing device provided by the patented announcement number CN222709571U, by setting a limiting slide groove and an electric push rod, and pulling the spray pipe through the connecting block, allows the spray pipe to move telescopically on the receiving pipe. By setting a support frame, worm gear and worm, the receiving pipe can be flipped and folded, and the spray pipe can be pushed out and stored. It is convenient to use and reduces the space occupied after use. At the same time, with the help of the trolley, it can spray the agent at multiple locations in the wastewater treatment tank, and can be used to dosing the agent for multiple sets of wastewater treatment tanks, reducing the installation cost of the dosing equipment.

[0004] However, this patent can only apply the drug to the surface of the sewage. The reaction speed of the drug is slow after application, the contact speed between the sewage at the bottom and the drug is slow, the application is uneven, and the treatment effect of the sewage at the bottom is not ideal. Therefore, an improvement is needed. So, a sewage treatment dosing device is proposed. Utility Model Content
