## Abstract

A bio-enhanced deodorization equipment includes a main body and a filler container in the main body. The filler container includes a wall and at least three perforated separator plates vertically arranged in the filler container. A plurality of spaces are formed by the at least three perforated separator plates, and a microbial filler and a carrier filler are accommodated in the spaces in an alternate manner.

## Claims

### Claim 1

A bio-enhanced deodorization equipment, comprising:
a main body;
a filler container;
a first cover;
an aeration pipe;
an air supply pipe; and
a second cover;
wherein a plurality of supports spaced apart are provided at a bottom of the main body; the first cover is arranged at the bottom of the main body and provided with a plurality of first openings spaced apart; the second cover is arranged on a top of the main body and provided with a plurality of second openings spaced apart; and the main body and the second cover are fixedly connected via a flange;
the aeration pipe is arranged in the main body and above the first cover; and the air supply pipe is arranged out of the main body and communicated with the aeration pipe; and
the filler container comprises a wall and at least three perforated separator plates vertically arranged in the filler container; a plurality of spaces are formed by the at least three perforated separator plates; and a microbial filler and a carrier filler are loaded in the spaces in an alternate manner.

### Claim 2 (depends on 1)

The bio-enhanced deodorization equipment of claim 1, wherein the first cover is welded to the main body.

### Claim 3 (depends on 1)

The bio-enhanced deodorization equipment of claim 1, wherein the aeration pipe consists of two aeration pipes in two loops.
