[0002] Municipal engineering refers to municipal infrastructure construction projects. Municipal infrastructure refers to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas, towns (villages), and provide residents with paid or free public products and services based on government responsibilities and obligations. Various public infrastructure construction supporting urban life falls within the scope of municipal engineering. For example, common urban roads, bridges, subways, underground pipelines, tunnels, rivers, rail transit, sewage treatment, garbage disposal and other projects all fall within the scope of municipal engineering. In the production and construction of municipal engineering, a large amount of sewage will be generated. In order to avoid pollution to the environment and harm to the human body, the generated sewage will be treated before discharge.

[0004] 1. The existing municipal engineering sewage treatment equipment is difficult to directly clean up the large volume of garbage in the sewage, resulting in the need for workers to salvage and clean up in advance during the sewage treatment process, which indirectly reduces the work efficiency and increases the workload of the workers, and cannot meet the use requirements;

[0005] 2. The existing sewage treatment equipment for municipal engineering projects does not have a deodorization mechanism, which causes a large amount of odor to be generated during the sewage treatment process. This not only affects the surrounding working environment, but also poses a serious threat to the health of the staff, indirectly reduces the safety of the work, and is inconvenient to promote.

[0014] Compared with the prior art, the utility model provides a sewage treatment device for municipal engineering, which has the following beneficial effects:

[0015] 1. This sewage treatment device for municipal engineering, when sewage enters the screen drum through the water inlet, first blocks the garbage in the sewage through the screen drum, so that the sewage can enter the sewage treatment tank through the through port for purification, and then drives the spiral blades to rotate inside the screen drum by starting the motor, so that the garbage located at the right end of the screen drum is transported to the left end of the screen drum until it falls through the discharge port for recovery and cleaning. This design allows the device to directly clean up large garbage in the sewage, avoiding the problem that the staff needs to perform salvage and cleaning work in advance during the sewage treatment process, indirectly improving the work efficiency, while reducing the work intensity of the staff, meeting the use requirements.

[0016] 2. This sewage treatment device for municipal engineering, during the sewage treatment process, starts the fan to discharge the airflow in the deodorization box, and then the suction pipe sucks the odor in the sewage treatment box into the deodorization box, so that the odor passes through the activated carbon layer and is adsorbed by the activated carbon. At the same time, the clean air can be discharged by starting the fan and integrated into the air. This design avoids the problem that the device will generate a large amount of odor during the sewage treatment process, which not only affects the surrounding working environment, but also poses a serious threat to the health of the staff. It indirectly improves the safety of work and is easy to promote. BRIEF DESCRIPTION OF THE DRAWINGS
