Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment equipment, and specifically to a multi-stage advanced treatment device for domestic sewage. Background Art

[0002] Domestic sewage is the wastewater discharged in residents' daily life, mainly from residential buildings and public buildings. The pollutants contained in domestic sewage are mainly organic matters (such as proteins, carbohydrates, fats, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and enteric infectious viruses, etc.). The organic matters existing in domestic sewage are extremely unstable and easily rot to produce a foul smell. Bacteria and pathogens multiply in large numbers using the organic matters in domestic sewage, which can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before discharge.

[0003] At present, the treatment of domestic sewage mostly uses multiple groups of simple filter nets to achieve multi-stage filtration, and the treatment effect is poor. Therefore, in view of the above situation, there is an urgent need to develop a multi-stage advanced treatment device for domestic sewage to overcome the deficiencies in current practical applications. Summary of the Invention

[0004] The purpose of the present invention is to provide a multi-stage advanced treatment device for domestic sewage to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A multi - stage advanced treatment device for domestic sewage, comprising: a sedimentation tank, the top tank wall of the sedimentation tank is fixedly connected to the water inlet pipe, and the side wall is fixedly connected to the flocculant feeding pipe, which is used to achieve the flocculation and sedimentation of sewage; a disinfection tank, the disinfection tank is arranged outside the sedimentation tank, the top tank wall is fixedly connected to the disinfectant feeding pipe, and the bottom side wall is connected to the drain pipe, which is used to complete the disinfection of sewage; an anti - clogging drainage unit, the anti - clogging drainage unit is arranged between the sedimentation tank and the disinfection tank, which is used to achieve the diversion and transportation of the sewage after sedimentation treatment, and complete the multiple purification of sewage; a synchronous stirring unit, the synchronous stirring unit is fixedly connected to the disinfection tank, leads to the inner tank of the disinfection tank, and leads to the inside of the sedimentation tank, which is used to achieve the synchronous stirring of the sewage inside the disinfection tank and the sedimentation tank; a self - recycling decontamination unit, the self - recycling decontamination unit is connected to the sedimentation tank and is arranged opposite to the output end of the water inlet pipe, which is used to filter the sewage entering the inside of the sedimentation tank and complete the automatic recycling of the filtered impurities; wherein, the self - recycling decontamination unit includes: a delay - driven filtering component, an automatic reciprocating cleaning component and a detachable sewage collection component, the delay - driven filtering component is arranged outside the bottom end of the water inlet pipe and is connected to the sedimentation tank, which is used to achieve the preliminary filtration of sewage, both sides of the delay - driven filtering component are abutted with detachable sewage collection components connected to the sedimentation tank, and an automatic reciprocating cleaning component connected to the sedimentation tank is also arranged between the delay - driven filtering component and the water inlet pipe, the automatic reciprocating cleaning component is also connected to the delay - driven filtering component, which is used to cooperate with the operation of the delay - driven filtering component to clean the impurities on the surface of the delay - driven filtering component and make them fall into the detachable sewage collection components on both sides.

[0006] Compared with the prior art, the beneficial effects of the present invention are: When the device is running, sewage enters the inner side of the sedimentation tank along the inlet pipe. The delay-driven control type filtering component filters the impurities in the sewage. The filtered sewage falls into the inner side of the sedimentation tank. The flocculant enters the inner side of the sedimentation tank along the flocculant feeding pipe. The synchronous stirring unit stirs the sewage in the inner side of the sedimentation tank, so that the sewage and the flocculant can be fully mixed to complete flocculation sedimentation. The sewage after sedimentation treatment enters the inner side of the disinfection tank along the anti-blocking drainage unit. The disinfectant enters the inner side of the disinfection tank along the disinfectant feeding pipe. The synchronous stirring unit can also stir the sewage located in the inner side of the disinfection tank, so that the disinfectant can be fully contacted with the sewage to achieve full disinfection of the sewage. The sewage after multiple purifications is discharged along the drain pipe. During the process of the delay-driven control type filtering component filtering the sewage, it can also drive the automatic reciprocating cleaning component. The automatic reciprocating cleaning component sweeps the impurities located on the delay-driven control type filtering component into the inner sides of the two detachable sewage collection components, avoiding blockage during the operation of the equipment and ensuring the continuity and effectiveness of purification. Compared with the prior art, most of the treatment of domestic sewage uses multiple groups of simple filter nets to achieve multi-stage filtration, and the treatment effect is poor. By setting the self-recovery type sewage removal unit, cooperating with the anti-blocking drainage unit and the synchronous stirring unit, it can perform multiple effective purifications on the sewage, and can also automatically recycle the filtered impurities, ensuring the continuity and effectiveness of purification and greatly improving the purification effect.
