Embodiment Construction

[0029] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0030] The technical scheme of concrete implementation of the present invention is:

[0031] like figure 1 As shown, a buried sedimentation tank for sewage treatment, including a vertical polyethylene tank;

[0032] The tank body comprises: a flat disc-shaped bottom plate, a vertical cylindrical surrounding wall 1 whose bottom end is connected to the edge of the bottom plate, and a spherical crown-shaped top cover 2 connected to the top of the surrounding wall 1 and protruding outward; the bottom plate, The surrounding wall 1 and the top cover 2 are integrally formed;

[0033] The tank body is provided with a vertical funnel-shaped mud-gathering bucket 3...

Abstract

The invention discloses a buried sedimentation tank for sewage treatment. The sedimentation tank comprises a vertical tank body, wherein the tank body comprises a bottom plate, enclosure walls and a top cover, wherein a vertical funnel-shaped mud gathering hopper is arranged in the tank body; a vertical cylindrical inspection port is formed in the top of the top cover; a sludge output pipe is fixed on the side wall of the inspection port, penetrates through the side wall of the inspection port and stretches into the mud gathering hopper; the bottom end of the sludge output pipe is connected with a sludge output pump; a water inlet pipe is fixed on the top cover; an inclined pipe is arranged in the tank body; the top end of the inclined pipe is communicated with the water inlet pipe through a first downstream tee joint; the bottom end of the inclined pipe is positioned in the mud gathering hopper; the bottom end of the inclined pipe is opened; and the opening in the bottom end of the inclined pipe faces the inner wall of the mud gathering hopper. The buried sedimentation tank for sewage treatment disclosed by the invention is capable of performing sedimentation treatment on sewage, and is good in sewage sedimentation effect; and moreover, the sedimentation tank is reasonable in structure, high in mechanical strength and durable, and the tank body can be buried underground.

Description

technical field [0001] The invention relates to an underground sedimentation tank for sewage treatment. Background technique [0002] Traditional sewage treatment sedimentation tanks are mainly square sedimentation tanks made of concrete. The construction period is long, and there are potential dangers such as corrosion, leakage and groundwater pollution. Moreover, the sedimentation speed of sewage is slow and the efficiency is low. Contents of the invention [0003] The purpose of the present invention is to provide an underground sedimentation tank for sewage treatment, which can carry out sedimentation treatment on sewage, and has a good sewage sedimentation effect; and has a reasonable structure, the tank body can be buried underground, has good mechanical strength and is durable. [0004] In order to achieve the above object, the technical solution of the present invention is to design a kind of underground sedimentation tank for sewage treatment, including a vertical...
