Micro-net component with rotary mobile micro-net body distributed with shock absorption and continuous line-shaped backwash

Abstract

The invention relates to a micro-net component with a rotary mobile micro-net body distributed with shock absorption and continuous line-shaped backwash, comprising a micro-net box body and a backwashpipe. The micro-net component is characterized in that the micro-net box body consists of an upper sealing cover plate and a lower sealing cover plate, a left squirrel cage-shaped rolling cylinder and a right squirrel cage-shaped rolling cylinder, a cambered baffle and a plurality of water collecting pipes with convex wings and the micro-net body; the left rolling cylinder and the right rolling cylinder are arranged between the upper sealing cover plate and the lower sealing cover plate, and one of which is connected with a driving mechanism; the micro-net body winds the left and the right rolling cylinders to constitute a closed ring and is connected with the upper sealing cover plate and the lower sealing cover plate in a sealing and sliding manner; the rotation speed is 1-5m / H; the water collecting pipes which use the convex rings to push the micro-net body for even distribution, the cambered baffle which surrounds the inner diameter of one rolling cylinder and the backwash pipe which uses a water injection nozzle for pushing the micro-net body at the junction of the end of the micro-net body rolled into the rolling cylinder and the cambered baffle are vertically fixedly arranged between the upper sealing cover plate and the lower sealing cover plate; a scraper is arranged on the outside of the micro-net body; and an interference water outlet is arranged on the lower part of the rolling cylinder of the cambered baffle and below the cylinder. The micro-net component has the advantages of large film generation area, stable effluent water flux and water quality, small cavity of the box body and high yield.

Description

technical field

[0001] The invention relates to a membrane module for membrane bioreactor technology in the field of sewage and wastewater treatment, in particular to a rotary membrane module with the synergistic effect of microbial bacteria micelles and micro-fine filter screens (commonly referred to as micro-screens in the industry) to achieve the effect of microfiltration solid-liquid separation. The moving micro-grid distributes vibration and continuously backwashes the micro-grid assembly. Background technique

[0002] Membrane Bio Reactor (MBR for short) is a new type of water treatment device that combines sewage and wastewater biological treatment technology with membrane separation technology. The characteristics of low sludge volume have been widely used in the field of water treatment, especially in sewage and wastewater recycling projects. However, MBR has the disadvantages of high component cost, short service life, flux drop, clogging, deep membrane fouling an...
