Abstract

The invention relates to the technical field of treating sewage by utilizing a biological technology and discloses an energy-saving type treatment device for MBR (membrane biological reactor) oxidation ditch sewage. The energy-saving type treatment device comprises an oxidization ditch biochemical reaction region and a membrane region, wherein a straight gallery of the membrane region and an S-shaped gallery of the oxidization ditch biological reaction region are in butt joint from the beginning to the end to form a circulating gallery; a penetrating tracery wall flat plate is overhead arranged on the bottom of the membrane region and used for dividing the membrane region into a membrane tank and a water distribution region from top to bottom; water distribution holes are uniformly distributed in the penetrating tracery wall flat plate; a membrane region water inlet is formed in the front end of the water distribution region; a membrane assembly and a water outlet tube are arranged in the membrane tank; the oxidization ditch biological reaction region is equipped with a water inlet device, a residual sludge outlet, a pushing device and an aeration device. According to the energy-saving type treatment device disclosed by the invention, the oxidization ditch process is organically combined with the membrane biological reactor; by utilizing hydraulic operation characteristics of large-flow circulating plug-flow state of the oxidization ditch process, mixed liquor in a groove is circulated and quickly flows through an MBR membrane set to realize solid-liquid separation, and therefore, the energy-saving type treatment device has the advantages of simple and compact structure, low operation energy consumption, small floor area, less investment, high pollutant removing efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of using biological technology to treat sewage, and relates to an MBR oxidation ditch sewage treatment device. Background technique [0002] The aggravation of the deterioration of water environment quality has put forward higher standards for the sewage treatment rate and treatment degree; The adverse effects of the environment have put forward more stringent requirements. Among them, the development and application of high-efficiency and low-consumption sewage advanced treatment technology and equipment has become a hot spot in water environment governance. [0003] MBR (membrane bioreactor) is a sewage treatment technology that combines membrane separation technology with biological treatment. It has good solid-liquid separation effect (membrane filtration method) and small footprint (no secondary sedimentation tank) , less excess sludge discharge (high sludge concentration, long sludge age), high degre...
