Sewage treatment device capable of performing multi-stage filtration on sewage

Abstract

The invention discloses a sewage treatment device capable of performing multi-stage filtration on sewage, relates to the technical field of sewage treatment, and aims to solve the problems that an existing sewage multi-stage treatment device generally needs to be provided with a plurality of tank bodies for conveying and guiding materials, so that multi-stage treatment measures can be completed, the overall occupied area of the device is large, and the treatment efficiency is low. The second-stage filtering mechanism is installed below the first-stage filtering mechanism and is in flange connection with the first-stage filtering mechanism through a flange plate, the number of the third-stage filtering mechanisms is four, and the four third-stage filtering mechanisms are mutually welded and connected and are all arranged below the second-stage filtering mechanism; the periphery of the lower surface of the second-stage filtering mechanism is fixedly connected with a third-stage filtering mechanism through a first bracket, the lower part of the third-stage filtering mechanism is fixedly connected with a temporary storage tank through a second bracket, and a feeding pipe is mounted at the upper end of the first-stage filtering mechanism.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device capable of multi-stage filtering of sewage. Background technique [0002] Sewage treatment technology is a variety of economical, reasonable, scientific and effective methods for urban domestic sewage and industrial wastewater. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, Dining and other fields. The urban sewage treatment process should be optimized and determined after a comprehensive technical and economic comparison based on the treatment scale, water quality characteristics, environmental functions of the receiving water body, and local actual conditions and requirements. For the multi-stage treatment of sewage, it is a process of advanced treatment of sewage step by step relying on primary, secondary, and tertiary treatmen...
