Abstract

The invention discloses a sedimentation tank and a sewage treatment system, and the sedimentation tank comprises: first sludge discharge grooves, which are a plurality of V-shaped tanks arranged in parallel; and second sludge discharge grooves which are a plurality of V-shaped grooves arranged in parallel, wherein the V-shaped grooves of the first sludge discharge grooves and the V-shaped grooves of the second sludge discharge grooves are staggered and parallel; a plurality of sludge discharge pipes are respectively arranged at the bottoms of the V-shaped grooves of the first sludge discharge grooves and the second sludge discharge grooves; a sludge discharge pipe arranged at the bottom of the first sludge discharge groove penetrates through the V-shaped bulge between the V-shaped grooves of the two second sludge discharge grooves; and mud inlet holes are formed in the parts, arranged in the V-shaped grooves of the first mud discharge groove and the second mud discharge groove, of the mud discharge pipe. According to the sedimentation tank disclosed by the invention, by arranging the staggered V-shaped groove bottoms and the sludge discharge pipes which are arranged in parallel, the sludge discharge efficiency is improved, so that the sludge at the bottom of the tank can be uniformly sucked, the moisture brought out by the sludge discharge pipes is reduced, and the sludge discharge efficiency and the sludge discharge quality are improved. The working efficiency is integrally improved, the construction, operation and maintenance cost is reduced, and the sludge outlet quality and the water outlet quality are improved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a 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. In the actual application of the existing sedimentation tanks, poor sludge discharge, high water content in the sludge discharge and poor drainage quality often occur.
