Description

Technical Field

[0001] This utility model specifically relates to the field of rainwater and sewage treatment technology, and more specifically to a rainwater and sewage treatment device for municipal management. Background Technology

[0002] Municipal stormwater and sewage treatment is a key component of urban infrastructure construction and environmental protection, mainly involving multiple processes such as the collection, transportation, treatment, and discharge of rainwater and sewage. Municipal stormwater and sewage treatment is of paramount importance to urban water environment quality, water resource utilization, and flood control and drainage. A good stormwater and sewage treatment system can effectively reduce urban flooding, improve the water quality of urban rivers, lakes, and other water bodies, and protect the ecological environment.

[0003] Traditional primary treatment of rainwater and sewage mainly uses physical methods, which can only remove large suspended solids and some sand particles from sewage. The effect on removing dissolved organic matter and nutrients in sewage is limited. Although secondary treatment uses biological treatment methods to remove most organic matter, it is not capable of treating some recalcitrant organic matter and trace pollutants (such as drug residues, endocrine disruptors, etc.).

[0004] A search revealed that Chinese patent application CN202320749592.1 discloses a municipal stormwater and sewage collection and filtration system. The system includes a collection box containing a filtration assembly. The filtration assembly comprises a guide frame, connecting components, a fixed frame, a filter screen, a connecting block, and a return spring. The guide frame is connected to the inside of the collection box via the connecting components. The fixed frame is fixedly connected to the bottom of the guide frame. The connecting block is fixedly connected to the side of the filter screen. The inner wall of the fixed frame has a moving groove adapted to the connecting block. One end of the return spring is fixedly connected to the inner bottom wall of the moving block, and the other end is fixedly connected to the bottom of the connecting block. The connecting components include a fixed block, a guide block, a locking post, a pull rod, and a contact spring.

[0005] The aforementioned patent, when treating rainwater and sewage, can only filter out larger impurities through a filter screen and filter out easily adsorbed impurities in the rainwater and sewage through an activated carbon adsorption layer. However, there are still impurities in the rainwater and sewage that are difficult to decompose. If they cannot be effectively filtered, they may cause pollution to land and water resources. However, the device in the aforementioned patent obviously cannot filter out harmful substances in the rainwater and sewage. Utility Model Content

[0006] The purpose of this invention is to provide a rainwater and sewage treatment device for municipal management. In this structure, rainwater and sewage are drawn into the tank through an inlet assembly. Larger impurities are filtered through a filter assembly inside the first treatment chamber.
