A sloping plate type mbr plate type membrane device

Abstract

The invention discloses an inclined plate type MBR (Membrane Bio-Reactor) plate membrane device. The inclined plate type MBR plate membrane device comprises a frame body, wherein the frame body is provided with a positioning shaft and a horizontal movement shaft; the horizontal movement shaft is provided with a slide groove; the positioning shaft is located in the slide groove; a rotating mechanism is arranged outside the frame body; a rotary table is connected onto the rotating mechanism; a transmission shaft is hinged to the eccentric part of the rotary table; the other end, relative to the rotary table, of the transmission shaft is hinged to the horizontal movement shaft; the frame body is obliquely provided with a plate membrane; the two ends of the plate membrane are hinged to the horizontal movement shaft and the frame body respectively. Therefore, an acting force for washing the surface of the membrane is formed on the plate membrane in a vertical upward flowing process of air bubbles and the possibility of blocking membrane holes is alleviated to the great extent; the service life of the plate membrane is prolonged and the difficulty of daily washing is reduced, so that operation and maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of research and development and application of membrane separation technology, and more specifically relates to a slanted plate type MBR plate type membrane device. Background technique [0002] The "Water Ten Rules" and the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" draft for comments put forward higher requirements for the effluent water quality of sewage treatment facilities. Traditional technology can no longer meet the increasingly stringent discharge requirements. And popularization provides a broader platform. Since the MBR process was introduced into China, it has been accepted by people for its stable operation, small footprint, high-load water inflow and high-quality effluent. However, some outstanding defects of the existing MBR process have been exposed in many years of application, which limits the popularization of the MBR process in recent years. MBR is divided into ho...

Problems solved by technology

The disadvantages of this vertical placement of membrane plates are as follows: 1. The air bubbles are uneven. During the actual operation, it was found that when the air bubbles pass through the gaps between the membrane plates, the amount of air bubbles passing through each membrane plate is uneven, or even no air bubbles pass through; Incomplete flushing, air bubbles flow vertically upward, parallel to the surface of the plate membrane, the force is small, particles are easily adsorbed on the surface of the membrane, and after a period of operation, the membrane pores are prone to clogging
