Improved sewage treatment quick carbon separating device

Abstract

The invention relates to the technical field of water treatment. In order to solve the technical problem of the prior art, the invention provides an improved sewage treatment quick carbon separating device which comprises a frame, an annular filter belt, a surge sucking device, a clean water collecting tank and a filter belt cleaning device, wherein the annular filter belt is arranged at the top of the frame; the surge sucking device is arranged at the bottom of an upper belt body of the annular filter belt; the clean water collecting tank is arranged on a web part of the frame; the device is characterized in that a plurality of rollers in the surge sucking device are in the manner of synchronously initiative rotating; a negative pressure water suction tank is arranged at the bottom of the upper belt body of the filter belt; the negative pressure water suction tank is connected with a negative pressure suction device in the improved sewage treatment quick carbon separating device. The present sewage treatment quick carbon separating device is improved, so that the sewage treating efficiency is further increased; the filter belt is more thoroughly cleaned; the suspended solids adhered to the surface of the filter belt can be effectively removed; the filter belt can be prevented from being blocked; the energy consumption is further reduced.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a rapid carbon separation device for sewage treatment. Background technique [0002] The applicant applied for a Chinese patent on January 29, 2016, application number: 201610059680.3, a rapid carbon separation device for sewage treatment. device and surge suction under the filter belt. The device can be used to quickly separate the suspended matter in the sewage, but in the process of application, it is found that the device still has certain technical problems, and the problems mainly focus on the following aspects: 1. The surge suction device under the filter belt The efficiency is low, and it can meet the application in the treatment of small water volume. When the inflow of sewage increases, the filtration efficiency of the filter belt obviously cannot meet the needs, and a large amount of sewage is brought to the top of the upper belt with the filter belt going up,...

Problems solved by technology

The device can be used to quickly separate the suspended matter in the sewage, but in the process of application, it is found that the device still has certain technical problems, and the problems mainly focus on the following aspects: 1. The surge suction device under the filter belt The efficiency is low, and it can meet the application in the treatment of small water volume. When the inflow of sewage increases, the filtration efficiency of the filter belt obviously cannot meet the needs, and a large amount of sewage is brought to the top of the upper belt with the filter belt going up, causing sewage overflow; 2. The filter belt cleaning device uses clean water spray pipes and gas spray pipes for flushing, which consumes a lot of energy, and it is difficult to remove some viscous suspended matter from the filter belt; 3. Although in A water distributor has been added to the existing device, but when the sewage flow rate increases, the sewage pressure is high, causing the sewage to be directly sprayed to the front end of the water distributor, causing the sewage to be replenished near the top of the upper belt, and the sewage cannot be obtained effectively dealt with and taken away
