Technical Field

[0002] With the acceleration of urbanization, urban sewage treatment has become a major problem that must be faced now. Therefore, in the process of treating sewage, municipal engineering needs to comprehensively consider the specific conditions of the city, reasonably select pipes, control the quality of sewage treatment, and add impetus to the sustainable development of the city.

[0003] According to the announcement number: CN219971889U, a municipal sewage treatment device with a solid-liquid separation function is proposed. The top plate of the body is installed with a power body, and the output end of the power body is fixedly connected with an output rod. The inner wall of the sewage filtering body is provided with a partition disc body, and the bottom plate of the partition disc body is installed with a partition net body. The mounting ring at the center of the partition net body is threadedly connected with the output rod. Start the power body, and the power body drives the output rod to rotate, so that the partition net body passes through the partition disc body on the outer wall of the receiving plate, and is translated upward through the cooperation of the slider body and the slide groove body. The partition net body moves the separated solid garbage to the opening of the solid-liquid separation box, which is convenient for handling. It solves the problem that the existing sewage treatment device generally filters the solid and liquid garbage in the sewage in a unified manner, so it is necessary to clean the sewage treatment device in time. Otherwise, the solids in the water will accumulate for a long time, and it is easy to get blocked, which affects the normal sewage treatment work.

However, the sedimentation and filtration processes require the sewage to be separated by itself, which results in a long time for solid-liquid separation and reduces the sewage treatment efficiency. In order to solve the above problems, a solid-liquid separation device for municipal sewage treatment is proposed. Utility Model Content
