Urban sewage treatment system based on internet of things

Abstract

The present application relates to the field of sewage treatment, in particular to a kind of urban sewage treatment system based on Internet of Things. Including the grid pool, sand tank, anoxic tank, anaerobic tank, aerobic tank, sludge thickening tank and disinfection tank connected in sequence, wherein the aerobic tank is provided with membrane filtration unit and aeration unit, membrane filtration unit includes a plurality of membrane assemblies that are equally spaced along the length direction of aerobic tank, membrane assembly is provided with flow sensor, aerobic tank is provided with membrane treatment mechanism corresponding to each membrane assembly, membrane treatment mechanism includes rotating frame and sliding frame, when sliding frame slides from top to bottom along slide groove, membrane surface of different height is sequentially close to aeration unit, forming gradient flushing mode. The present application knows membrane flux condition of membrane assembly through Internet of Things monitoring, is conducive to starting membrane treatment mechanism in time, so that membrane assembly slides with sliding frame inclination, combined with aeration to flush membrane surface in section, effectively maintain flux stability, ensure that sewage treatment system runs stably.
