Coagulation sedimentation tank apparatus

Abstract

The invention relates to a coagulation sedimentation tank apparatus. The coagulation sedimentation tank apparatus comprises an outer barrel body, an inner barrel body, a stirring assembly, a mud scraping assembly and a driving assembly, wherein the outer barrel body is provided with a cavity, the bottom of the outer barrel body is obliquely arranged to form a conical structure, and the bottom of the outer barrel body is provided with a mud outlet; the inner barrel body is installed in the outer barrel body and provided with an outlet; the stirring assembly is arranged in the inn barrel body; the mud scraping assembly is close to the bottom of the outer barrel body; and the driving assembly is separately connected with the stirring assembly and the mud scraping assembly by virtue of a mainshaft and used for driving the stirring assembly and the mud scraping assembly to rotate. According to the invention, by adding the stirring assembly and the bottom mud scraping assembly and designingthe inner and outer barrel bodies, the coagulation effect and the sludge sedimentation efficiency of the apparatus are greatly improved, the retention time of clear water on the upper layer is increased, and the sedimentation effect is better; and meanwhile, the bottom mud scraping assembly can slowly collect the precipitated sludge to a bottom mud discharging port, thereby facilitating the discharging of the sludge discharge and reducing the blockage phenomenon caused by sludge solidification.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, and more specifically, to a coagulation sedimentation tank device. Background technique [0002] The sewage collected by wet sweepers has a large content of sludge and sand, and it is directly discharged into the urban underground sewage pipe network without treatment, which is likely to cause blockage of the urban sewage pipe network and affect the normal drainage and drainage capacity of the city. The SS content in the sewage collected by the wet sweeper is large, which seriously exceeds the standard required for the SS content in urban sewage discharge. It is directly discharged through the municipal sewage pipe network, which does not meet the relevant regulations of the environmental protection department. It must be purified and discharged after reaching the standard. [0003] General sewage sedimentation devices include natural sedimentation tanks and inclined plate sedimentatio...
