Fiber Bundle Filtration Membrane Bioreactor

Abstract

The invention discloses a fiber bundle filter membrane biological reaction device, which comprises a biological reaction tank, the biological reaction tank includes a water inlet, a water outlet, and an aeration port, and the biological reaction tank is covered with bacteria for degrading organic matter. Comprising an unconstrained fiber bundle filter system, the unconstrained fiber bundle filter system includes an unconstrained fiber bundle filter; the unconstrained fiber bundle filter includes a container, a lower porous plate in the lower part of the container, and a fiber bundle accumulation layer in the container , the fiber bundle accumulation layer is composed of a number of fiber bundles freely accumulated on the lower porous plate; the water outlet of the biological reaction tank is connected with the unconstrained fiber bundle filter. The invention has a simple structure, is easy to clean, and can reduce production and maintenance costs.

Description

technical field [0001] The invention relates to a membrane bioreactor, in particular to a membrane bioreactor which utilizes freely accumulated fiber bundles for filtering. Background technique [0002] In the field of sewage treatment, the membrane bioreactor, which has developed rapidly in recent years, occupies a very important position. It has a high ability to degrade organic matter, not only has less sludge discharge, but also has good effluent quality, which can be directly used as reclaimed water or further used to prepare pure water. Existing membrane bioreactors are equipped with a set of filters with high filtration accuracy at the water outlet, one is to improve the water quality after treatment, and the other is to increase the density of the bacteria in the reactor, so as to prevent the reaction bacteria from being mixed with the product. Water loss reduces treatment efficiency. [0003] The most used filters in existing membrane bioreactors are: hollow fiber...

Problems solved by technology

[0003] The most used filters in existing membrane bioreactors are: hollow fiber ultrafilters, and filters composed of filter plates. The filtration principles of these filters are traditional membrane filtration, and the traditional membrane method The disadvantages of filtration are: complex structure, high cost, and difficult cleaning after fouling. For hollow fiber ultrafilters, there are more broken wires and cleaning problems during operation, which shortens the service life of the filter and increases Membrane Bioreactor Operation and Maintenance Costs
