Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to an integrated urban domestic sewage sludge treatment device. Background Technique

[0002] Urban domestic sewage is the wastewater discharged in residents' daily life, mainly from residential buildings and public buildings, such as residences, government agencies, schools, hospitals, stores, public places, and industrial enterprise restrooms. With the improvement of people's living standards, the discharge of domestic sewage is becoming more and more serious. The organic matter in domestic sewage is extremely unstable, easily rots and produces malodors. Bacteria and pathogens multiply in large numbers using the organic matter in domestic sewage as nutrients, and it will also lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before discharge.

[0003] In the existing sewage sludge treatment technologies, for example, the prior art with the application number CN202320030724.5 includes a treatment equipment main body, a first rotation drive mechanism, a water inlet, a filter screen, a fixed frame, a conveying mechanism, and a second rotation drive mechanism, etc. Sewage enters the treatment equipment main body through the water inlet, and impurities such as floating objects in the sewage are intercepted and filtered by the filter screen. When the impurities in the filter screen accumulate, the first rotation drive mechanism drives the fixed frame on the filter screen to rotate through a rotating shaft, so that the filter screen flips.

[0004] However, the prior art is not convenient for flocculating and precipitating sewage, and it is not convenient to monitor the amount of flocculant, resulting in reduced practicability. Moreover, the prior art is not convenient for maintenance and replacement, resulting in reduced practicability. Content of the Utility Model
