Description

Technical Field

[0001] The utility model relates to the technical field of treatment equipment, in particular to a surround-type multi-layer sewage treatment device. Background Art

[0002] Wastewater treatment typically includes primary and secondary treatment. Generally speaking, if the treated effluent is discharged into a municipal sewer, only primary treatment is typically performed. If the treated effluent is discharged directly into a river, both primary and secondary treatment are required. In areas with strict discharge standards, tertiary treatment for phosphorus and nitrogen removal is required to prevent eutrophication. Special hospital wastewater, such as acidic wastewater, phase wash water, and radioactive wastewater, requires rigorous collection and treatment. Some regions have implemented advanced wastewater treatment and recycling to alleviate water supply constraints.

[0003] The existing sewage treatment device does not have the function of circulating disinfection, which easily leads to uneven mixing of sewage and disinfectant water, affecting the disinfection effect. Therefore, a surrounding multi-layer sewage treatment device is proposed.

[0004] A surround-type multi-layer sewage treatment device is disclosed in announcement number CN208150999U. Although the surround-type multi-layer sewage treatment device has a structure including supporting feet, a sewage treatment tank body, an observation window, a discharge end, a discharge pipe, screws, a water volume adjustment device, a control box, an indicator light, a sewage inlet, and a button, the right surface of the discharge end is in contact with the left surface of the discharge pipe. The utility model is a surround-type multi-layer sewage treatment device, which is structurally provided with a water volume adjustment device. The water volume adjustment device is installed on the sewage treatment tank body, and the water level is detected by a water level sensor. When the water level is not enough, the electromagnetic coil is energized, and a magnetic field is generated by the electromagnetic coil, so that the lower contact and the upper contact are attracted, and the motor drives the gear, and the gear drives the rotating plate to rotate to discharge sewage. When the water level is too high, the water level sensor is not energized, and the water volume adjustment device is used to ensure the maximum filtration of sewage to prevent sewage from being discharged into the environment and polluting the environment.

[0005] Although the above patent has achieved the goal of generating a magnetic field through the electromagnetic coil, so that the lower contact and the upper contact are attracted, the motor drives the gear, and the gear drives the rotating plate to rotate to discharge sewage, when the water level is too high, the water level sensor is not energized, and the water volume regulating device is used to ensure the maximum filtration of sewage to prevent sewage from being discharged into the environment and polluting the environment; however, the device lacks the function of improving the sedimentation efficiency of sewage, and instead uses static sedimentation to treat sewage, which is less efficient.

[0006] Therefore, it is necessary to invent a surround-type multi-layer sewage treatment device to solve the above problems. Utility Model Content

[0019] 1. This surround-type multi-layer sewage treatment device is equipped with a stirring mechanism and a flocculant storage tank. When in use, sewage is poured into the sedimentation chamber, and then the flocculant is taken out of the flocculant storage tank and placed in the sewage.

[0020] 2. The surround-type multi-layer sewage treatment device, through the setting of the disinfection mechanism, opens the regulating valve and starts the circulation pump on one side of the filter chamber when performing sewage disinfection.
