Three-time precipitating and sterilizing-disinfecting device for sewage of black river channel

Abstract

The invention discloses a three-time precipitating and sterilizing-disinfecting device for sewage of a black river channel. The three-time precipitating and sterilizing-disinfecting device comprises adevice main body, wherein a primary precipitating tank is arranged at the left side of the device main body, and the right side of the primary precipitating tank is fixedly connected with the devicemain body; a top plate is arranged at the middle part of the primary precipitating tank, and is closely attached with the primary precipitating tank; a connecting plate is arranged at the left side ofthe top plate and is closely welded with the top plate. Compared with the common sewage purifying device, the three-time precipitating and sterilizing-disinfecting device disclosed by the invention has the advantages that the primary precipitating tank and a final precipitating tank are arranged, the sewage is filtered and primarily precipitated by a grid and then flows into the primary precipitating tank, the primary precipitating tank is internally provided with flow-slowing plates which are arranged in a crossing manner, so that the flowing speed of the sewage can be reduced, so that the action of secondary precipitation is achieved; then the sewage flows into the final precipitating tank by a connecting channel to carry out tertiary precipitation, so that the precipitating effect of the device for the sewage is effectively improved.

Description

technical field [0001] The invention relates to the technical field of sewage disinfection and purification, in particular to a device for tertiary sedimentation and sterilization of black river sewage. Background technique [0002] Sewage disinfection is a water treatment process that kills harmful pathogenic microorganisms in domestic sewage and some industrial wastewater treatment systems. Domestic sewage and some industrial wastewater not only contain a large number of bacteria, but also often contain viruses, amoeba cysts, etc. They cannot be exterminated through normal wastewater treatment processes. [0003] However, the existing sewage treatment equipment cannot achieve the effect of three precipitations, so that the precipitation of sewage is not comprehensive, which leads to the incomplete purification of sewage in the following purification procedures, and the existing sewage treatment equipment cannot achieve the purpose of sterilizing sewage. The role of disinf...
