Description

Installation mechanism of MABR component

Technical Field

The utility model relates to the technical field related to sewage treatment equipment, in particular to an installation mechanism of an MABR component.

Background

The membrane aeration-biofilm reactor technology (Membrane biofilm reactors, MBfR) is also known as membrane aeration bioreactor technology (Membrane Aerated biofilm reactor, MABR). Essentially a novel biofilm process capable of simultaneously achieving two functions through a membrane material:

(1) providing a carrier for easy attachment growth of the biological film;

(2) delivery of gaseous substrates (typically O) to biological membranes ₂ )。

Because of the special aeration mode and oxygen transfer mechanism of the MABR reactor, the microbial film can generate an obvious layered structure, and good synchronous nitrification-denitrification effect is generated. The main technical characteristics of the method can be summarized as three points: (1) bubble-free aeration, (2) heterogeneous mass transfer, and (3) a biomembrane layered structure.

There are two types of MABR reactors available:

(1) curtain type, using hollow fiber membrane wire as gas substrate transmission and biological film adhesion carrier;

(2) plate type film sleeve made of inner film roll is used as gaseous substrate transmission and biological film adhesion carrier (plastic supports are arranged on two sides), and the inner side of the film roll is aerated.

At present, the installation mode of MABR has fixed support installation (comprising beam column type, steel frame structure type and the like) according to different engineering cases.

These mounting forms have the following disadvantages:

1. the construction time is longer, the tank body needs to be emptied for installation, and the advantages of quick installation and no water cut-off installation of the MABR technology are lost;

2. beam columns or steel structures, etc. may adversely affect the flow regime within the biological pond.

3. The maximum wet weight of the membrane component needs to be considered in the installation of the fixed support, and the installation cost is high;

4. because the beam column/steel structure supporting piece is hidden under the water surface, the position is difficult to determine when overhauling and hoisting again, and therefore, additional hoisting sliding rails or hoisting beams are often required to be added to ensure the installation accuracy;

5. the hoisting installation has the requirement on the strength of the cover plate and the side wall of the pool; while the support mounting requires strength for both the tank Bian Bi and the tank floor;

6. in a single-side hanging installation mode, in order to ensure the stability of the installation of the membrane assembly, a certain space is needed at the tank edge, so that the counterweight support of the fixing piece is facilitated;

7. in order to ensure the flow state and the treatment capacity of an activated sludge process in the operation process, the aspect ratio of the biological pond has certain requirements, and when the side wall of the pond is hung and installed, the phenomenon of uneven load or short flow of a membrane module is easily generated if the corresponding length and width are not proper.

In summary, the conventional installation method of the fixed support and the fixed hoisting has high cost, and also has various limitations, and the original space is possibly wasted.
