High-efficiency energy-saving integrated MBR (membrane bioreactor) apparatus and sewage treatment method thereof

Abstract

The invention discloses a high-efficiency energy-saving integrated MBR (membrane bioreactor) apparatus and a sewage treatment method thereof, which belong to the field of sewage treatment. The apparatus comprises a reciprocating driving apparatus and a traveling apparatus, wherein the reciprocating driving apparatus consists of a driving motor and a slider-crank mechanism, the reciprocating driving apparatus is connected with the traveling apparatus of an MBR membrane assembly by virtue of a slide connecting rod, sludge-water mixed liquid in a membrane pool and the MBR membrane assembly are enabled to make regular and controllable relative movement so as to clean a membrane, and little bottom pulse aeration scrubbing is also adopted for assisting. By combining two membrane pollution preventing ways of reciprocating moving scrubbing and aeration scrubbing, the pollution of the MBR apparatus both in the horizontal direction and the vertical direction is effectively controlled, the energy consumption input of the two ways can be adjusted according to the real operation condition, and the membrane pollution is alleviated in an initiative and controllable way. Meanwhile, by controlling appropriate operation parameters, a best energy-saving effect is achieved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an efficient and energy-saving integrated MBR device and a sewage treatment method thereof. Background technique [0002] Membrane bioreactor (MBR) is a new water treatment technology that combines membrane separation unit and biological treatment unit. In recent years, due to the improvement of water treatment standards, the MBR process has gradually been recognized by the industry due to its stable and efficient treatment effect, and its engineering applications are increasing year by year. However, compared with other biological treatment methods, the effective control of membrane fouling leads to higher energy consumption, which to some extent limits the popularization and application of the MBR process. [0003] At present, the control of membrane fouling is basically carried out by physical means and chemical cleaning methods. The blower is used to aerate the perforated tu...
