Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment device for adding chemicals for sewage treatment. Background Art

[0002] A sewage treatment plant is a device or system used to treat sewage, which can convert wastewater containing various pollutants into water resources that can be discharged or reused. This plant is widely used in cities, industrial areas and rural areas, and plays an important role in protecting the environment and human health.

[0003] At present, in the prior art, a Chinese patent with announcement number CN218232001U discloses a sewage treatment device with a dosing agent. The device starts a driving motor 1, drives the rotating shaft to drive the medicine-distributing plate to rotate, and pours the flocculant from the dosing port. The medicine-distributing plate can disperse the flocculant in an orderly manner from the dosing pipe into the treatment box, and the medicine-distributing plate rotates continuously to avoid the flocculant from piling up. However, in actual use, the device may cause other power equipment in the treatment device to need additional operation because the purified sewage cannot be drained smoothly. The retained sewage stays in the treatment device for a long time, which may cause secondary pollution. The reproduction of microorganisms, the decomposition of organic matter and other processes may produce new pollutants. In view of this, we propose a sewage treatment device with a dosing agent for sewage treatment. Utility Model Content
