Embodiment 1

[0043] Such as Figure 1 to Figure 2 As shown, a municipal overflow sewage treatment device disclosed in the present invention includes a rectangular-like housing 1 , an inlet 11 is opened on the top of the housing 1 , and an outlet 12 is opened on the side of the housing 1 . The housing 1 is equipped with a filter device, a water storage tank 5 and a water storage bucket 6 from top to bottom along the height direction, and the solid-liquid separation of large volumes of solid waste is carried out through the filter device, and the larger solid waste is separated from the outlet. The feed port 12 is discharged to facilitate the collection of solid waste and the next step of processing.

[0044] The shell 1 is equipped with a feed tank 16 at the position of the discharge port 12. The feed tank 16 is a hollow inverted quadrangular platform type, and the sewage overflowed in the municipal engineering is introduced into the shell from the feed port 11 through the feed tank 16. In...

Embodiment 2

[0056] A municipal overflow sewage treatment method, comprising the steps of:

[0057] a. Introduce sewage: import sewage into feed port 11;

[0058] b. Garbage deposition: the conveyor belt 2 hooks the solid garbage in the sewage to separate the solid from the liquid;

[0059] c. Sewage magnetization: use the magnetic field generated by the electromagnet 4 to magnetize the sewage in the water storage tank 5;

[0060] d. Centrifugal sedimentation: the sewage in the water storage tank 6 is centrifugally stirred by using a centrifugal device, and the deposited silt and clear water are led out from the mud outlet pipe 15 and the water outlet pipe 14 respectively.

Abstract

The invention relates to an apparatus for treating municipal overflow sewage. The apparatus comprises a shell, the inner upper part of the shell is provided with a material inlet, a filtering device is arranged below the material inlet, the filtering device comprises a hollow-out conveyor belt, the conveyor belt moves relative to the shell, a plurality of limiting hooks perpendicular to the conveyor belt are slidably inserted into the conveyor belt, and a control device for controlling the sliding of the limiting hooks is arranged below the conveyor belt; the side surface of the shell is provided with a material outlet, and a material discharge plate extending to a position below the conveyor belt is mounted at the material outlet; and a water storage barrel is arranged below the filteringdevice, a centrifuging device is mounted in the water storage barrel, and the water storage barrel is communicated with a mud outlet pipe and a water outlet pipe. The filtering device is arranged topre-separate solid wastes, so obstruction is not prone to occur in the water storage barrel and the whole sewage treatment process.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a municipal overflow sewage treatment device and method. Background technique [0002] At present, the rapid development of urbanization has caused insufficient municipal sewage collection and treatment capacity, resulting in the phenomenon of overflow sewage flowing directly into the body, resulting in the continuous deterioration of the water environment. Municipal overflow sewage refers to that in rainy and snowy weather, when rainwater runoff flows into the urban municipal drainage pipe network, the flow of flushing sewage exceeds the carrying load of the drainage pipe network system. Except for part of it being transported to the sewage treatment plant, the rest of the large amount of flushing sewage will be discharged. Without treatment, it directly overflows into surface water bodies through pipelines, causing water pollution. In addition, under special circumsta...
