Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with accompanying drawing: Figure 1-3As shown, a device for improving SBR sewage treatment, which includes a slag separation adjustment tank 2 with a lift pump, a basket fine grid is set at the water inlet of the adjustment tank to intercept fine suspended solids and particles, and an immersion pressure level gauge is installed 29. Monitor and control the liquid level. The bottom is regularly aerated and stirred through the perforated tube aerator 26. At the same time, the water inlet end is welded with the water partition 1, and the bottom is passed through the water to realize the separation of floating objects and slag; the rear end is connected to two sets of parallel The SBR tank 3 and 4, the coagulation tank 11, the primary sedimentation tank 10, the secondary sedimentation tank 9, the packing filter tank 6, and the microporous aeration discs 24 and 25 are evenly arranged at the bottom of the S...

Abstract

The invention discloses an improved SBR sewage treatment device. The device comprises a separated slag regulating tank with a lifting pump, wherein the rear end of the slag separation regulating tankis sequentially connected with two sets of parallel SBR tanks, a coagulating tank, a first-stage sedimentation tank, a second-stage sedimentation tank and a filler filter tank, and the SBR tanks are not provided with a decanter. According to the invention, water production is achieved through a top water mode, triangular weirs are arranged around the tops of the SBR tanks to collect SBR effluent,movable cuboid-shaped fixed filler assemblies are arranged in the tanks, and soft combined fillers are suspended; and the filler filter tank adopts a modular structure capable of being rapidly replaced and can be replaced by treatment units with different depths according to different effluent standards. The improved SBR sewage treatment device is a brand-new intelligent control sewage treatment system with the advantages of simple hydraulic structure, less power equipment, less fault points, low operation energy consumption, low maintenance cost, convenience in use, long service life, modularflexible combination and full automation.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an improved SBR sewage treatment device and method. Background technique [0002] Looking at the processes used in the existing village and town sewage treatment facilities in my country, they are similar to urban sewage treatment facilities and are based on different combinations of physical and chemical treatment, biochemical treatment and natural ecological treatment. Among the existing village and town sewage treatment technologies in my country, those related to the activated sludge method mainly include: AO and its various deformation processes (such as A2O, oxidation ditch, SBR, etc.); the technologies related to the biofilm method mainly include: Biological filter, MBBR (Moving Bed Biofilm Reactor, moving bed biofilm reactor), biological contact oxidation, biological turntable, etc.; technologies related to natural ecological methods mainly include: constructed wet...
