Abstract

The invention belongs to the technical field of sewage treatment and cyclic utilization, particularly relates to a sewage treatment device for water conservancy construction, and aims to solve the problems that in the prior art, blockage response is delayed, grid sundries are accumulated and need to be shut down for cleaning, subsequent procedures are interrupted, a sedimentation tank mud scraper continuously runs, energy consumption and operation and maintenance are unbalanced, and energy cyclic utilization cannot be carried out. According to the scheme, the sewage treatment device comprises a sewage treatment tank, a water inlet bent pipe is arranged at the top of the sewage treatment tank, the bottom of the sewage treatment tank is open and fixedly provided with a bottom sealing cover, and three supporting legs are fixedly installed at the bottom of the bottom sealing cover; the multi-stage filtering mechanism is mounted in the sewage treatment tank; and a sludge leading-out structure. The pressure film is used for monitoring blockage in real time and automatically triggering cleaning, sludge potential energy is recycled to generate power for the system for self use, integrated rotary sludge scraping and high-pressure water backflushing are adopted, and 360-degree cleaning is achieved through self-produced purified water.
