Abstract

The invention discloses a vertical flow type sedimentation tank and a sewage treatment system, the vertical flow type sedimentation tank comprises a sludge discharge system arranged at the bottom of the sedimentation tank and a water inlet system arranged at the center of the top of the sedimentation tank, the sludge discharge system comprises a sludge bucket arranged at the bottom of the sedimentation tank, and the bottom end of the sludge bucket is communicated with a sludge discharge pipeline; the water inlet system is arranged at the top of the sedimentation tank, extends into the sedimentation tank and is used for enabling the sewage to enter the sedimentation tank and / or adding chemicals into the sewage; and a flow guide device is arranged right below the outlet of the water inlet system and is used for guiding sludge. According to the vertical-flow sedimentation tank disclosed by the invention, the flow guide device is arranged at the sludge hopper at the tank bottom, so that the sludge discharge efficiency is improved, the sludge at the tank bottom can be fully discharged, the moisture brought out by mixed discharge is reduced, the sludge discharge efficiency is improved, and the moisture content of the discharged sludge is reduced.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a vertical flow sedimentation tank and a sewage treatment system. Background technique [0002] Sedimentation tank is a kind of equipment that uses sedimentation to remove suspended solids in water and purify water quality. The working principle is to use the natural precipitation of water or the effect of coagulation and sedimentation to remove suspended solids in the water. The sedimentation effect depends on the flow rate of water in the sedimentation tank and the residence time of water in the tank. Sedimentation tanks have a wide range of market demands and applications in the field of water treatment, and almost all water treatment projects will use sedimentation tank technology. The bottom of the vertical flow sedimentation tank is a funnel-shaped cone. In existing practical applications, sludge settles, concentrates, and accumulates at the bottom of the tank. T...
