Problems solved by technology

Although such an operation method can realize the solid-liquid separation of sewage, during the long-term sewage filtration process, floating objects will continue to accumulate on the filter screen, thereby causing blockage of the filter screen, and the blocked filter screen needs to be replaced or replaced. to clean
In the process of replacing or cleaning the filter screen, the sewage inlet pipe needs to temporarily stop discharging sewage into the sewage treatment tank, and the sewage treatment will be temporarily interrupted.
In this way, the sewage inlet pipe cannot continuously discharge sewage into the sewage treatment tank, resulting in intermittent sewage treatment process and greatly reducing the sewage treatment efficiency

Embodiment 1

[0052] Embodiment 1, the water inlet of the sewage water inlet pipe is set at the notch of the solid-liquid separation tank 110 . In this way, the sewage in the sewage water inlet pipe can be directly discharged into the solid-liquid separation tank 110 of the solid-liquid separation tank 100 without any obstruction.

Embodiment 2

[0053] In the second embodiment, the water inlet of the sewage water inlet pipe runs through the side wall of the solid-liquid separation tank 110 . The sewage in the sewage water inlet pipe is discharged into the solid-liquid separation tank 110 from the side of the solid-liquid separation tank 100. When the sewage in the solid-liquid separation tank 110 reaches a certain depth, it will not pass the water inlet of the sewage water inlet pipe, so that the sewage does not flow. The wall of the solid-liquid separation tank 110 will be impacted, so that the sewage in the sewage water inlet pipe will be smoothly input into the solid-liquid separation tank 110 to provide a stable environment for subsequent solid-liquid separation.

[0054] Here, it should be noted that impurities such as sludge are inevitably mixed in the sewage, and during the process of the sewage flowing through the solid-liquid separation tank 110, the sludge will gradually precipitate. To this end, a sludge se...

Embodiment approach

[0089] like Figure 10 As shown in the first embodiment, a plurality of flow control fixing holes 412 are opened on the plate surface of the flow control fixing plate 410, the flow control fixing plate 410 is a circular disc structure, and the flow control fixing holes 412 are circular through-hole structures. The plurality of flow control fixing holes 412 are distributed in an annular array with the central axis of the flow control fixing plate 410 as the center.

[0090] like Figure 11 As shown in the second embodiment, a plurality of flow control fixing holes 412 are opened on the plate surface of the flow control fixing plate 410, the flow control fixing plate 410 is a circular disc structure, and the flow control fixing holes 412 are elongated through-hole structures , each flow control fixing hole 412 extends from the center of the flow control fixing plate 410 to the edge, and a plurality of flow control fixing holes 412 are distributed in an annular array with the ce...

Abstract

The invention discloses sewage treatment equipment which is used for treating sewage and achieving solid-liquid separation. The sewage treatment equipment comprises a sewage inlet pipe, a solid-liquidseparation tank, a floating object stirring device and a floating object fishing device, wherein the sewage inlet pipe is used for draining sewage to be solid-liquid separated into the solid-liquid separation tank; the solid-liquid separation tank is used for collecting the sewage to be solid-liquid separated and providing a middle transition space for feeding and discharging the sewage; the floating object moving device is used for stirring floating objects floating on the surface of sewage to one side, so that the floating objects can be gathered together, and convenience is brought to fishing; the floating object fishing device is used for fishing the floating objects floating on the surface of the sewage from the solid-liquid separation tank. According to the sewage treatment equipment disclosed by the invention, a traditional mode of utilizing a filter screen to perform solid-liquid separation is substituted; the sewage inlet pipe further can continuously drain the sewage into asewage treatment tank based on achieving separation of the floating objects from the sewage; thus, the sewage treatment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment equipment. Background technique [0002] Chinese invention patent, patent application number 201510797541.6, publication number CN106698713A, which discloses a solid-liquid separation system in sewage treatment, the tank body is separated from left to right by a partition plate, respectively, with a water inlet cavity, a mixing cavity, a gas A floating cavity, a sewage cavity and a drainage cavity, the water inlet pipe is communicated with the water inlet cavity of the pool body, the water inlet cavity is communicated with the mixing chamber through the water holes opened at the bottom of the partition plate, and the air filling pipe and the medicine feeding pipe are connected with each other. One end is respectively located at the bottom of the mixing chamber, the height of the baffles on the left and right sides of the air flotation chamber is lower ...
