Technical Field

[0001] The present invention relates to the technical field of sewage treatment, in particular to a sewage treatment agent spreading device for sewage treatment. Background Art

[0002] Sewage refers to water containing various wastewater and pollutants generated during human production, life and social activities. Sewage contains various pollutants such as organic matter, inorganic matter, microorganisms and heavy metals, which are harmful to the environment and human health. When treating sewage, sewage treatment agents are used to spray into the sewage. The treatment agents are mainly used to remove pollutants and odors in the sewage, flocculate impurities in the sewage, and achieve solid-liquid separation.

[0003] Regarding the above-mentioned related technologies, it is believed that when using sewage treatment agents, different sewage requires different treatment agents, which are mainly divided into two states of treatment agents: solid and liquid.

The liquid pump 51 extracts the uniformly mixed sewage treatment agent from the mixing drum 41 through the water inlet pipe 57. When the mobile frame 613 moves to the right, the main controller 2 controls the solenoid valve 53 on the left to close and the solenoid valve 53 on the right to open.

The solenoid valve 53 on the right is controlled to be closed, and the solenoid valve 53 on the left is controlled to be opened, so that when the movable frame 613 moves to the left, the sewage treatment agent pumped out by the liquid pump 51 is injected into the inside of the connecting pipe 54 on the right through the three-way pipe 52, and then evenly sprayed on the sewage inside the treatment tank 1 through the nozzle 55. The rotation and forward and backward movement of the stirring blade 68 can evenly stir the sewage treatment agent just sprayed into the inside of the treatment tank 1, so that the sewage treatment agent is fully mixed and reacted with the sewage, which can improve the uniformity of mixing.
