specific Embodiment approach 1

[0012] Specific Embodiment 1: The recyclable modular fixed bed biofilm reactor in this embodiment includes a fixed frame 1, two external pipes 2, an internal pipe, a fixed seat 5, a plurality of first delivery pipes 6, and a plurality of second delivery pipes 7. A plurality of first aeration pipes 8, a plurality of second aeration pipes 9 and the main pipe, the fixed frame 1 is a cuboid frame structure, and the two ends of the main pipe 13 are fixedly connected to the fixed frame 1 through the fixed seat 5 On the bottom frame of the main pipe 13, the first main pipe 13-1 and the second main pipe 13-2 are arranged in parallel and spaced along the height direction, and a plurality of first aeration pipes are respectively arranged on the left and right sides of the main pipe 13 8 and a plurality of second aeration pipes 9, the first aeration pipe 8 and the second aeration pipe 9 on each side are arranged alternately, the first main pipe 13-1 passes through the first delivery pipe ...

specific Embodiment approach 2

[0015] Embodiment 2: This embodiment differs from Embodiment 1 in that the microbial carrier filler is placed inside the fixing frame 1 .

[0016] In this embodiment, fixed filler is filled in the fixed frame 1 .

specific Embodiment approach 3

[0017] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the fixing member 10 is sleeved on the first aeration pipe 8 and the second aeration pipe 9 to fix the first aeration pipe 8 and the second aeration pipe. Tube 9 position.

Abstract

The invention discloses a recyclable modular fixed bed bio-membrane reactor, relates to the technical field of water treatment, and aims at solving the problems that an existing bio-membrane reactor is relatively large in limitation on difficulty in controlling the aeration rate, relatively high in cleaning difficulty and relatively high in mounting cost. A main pipeline in the recyclable modularfixed bed bio-membrane reactor is formed by arranging a first main pipeline and a second main pipeline in parallel at intervals in the height direction, a plurality of first aeration pipes and a plurality of second aeration pipes are arranged on the left side and the right side of the main pipeline respectively, and the first main pipeline communicates with the first aeration pipes through a firstconveying pipe; the second main pipeline is communicated with the second aeration pipe through a second conveying pipe; an inner pipeline is composed of two vertically-arranged pipelines, and the twoinner pipelines are communicated with the outer pipeline and the main pipeline respectively. According to the invention, the aeration amount can be flexibly controlled to realize a dual aeration effect, and meanwhile, the cleaning and updating of a biological membrane are realized by controlling the aeration intensity, so that the sewage treatment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a recoverable fixed-bed biofilm reactor module. Background technique [0002] The biofilm method is a sewage treatment method that uses biofilm to stabilize and clarify wastewater under sufficient oxygen supply conditions. Biofilm is an ecosystem composed of highly dense aerobic bacteria, anaerobic bacteria, facultative bacteria, fungi, protozoa and algae, and the solid medium attached to it is called filter material or carrier. The biofilm can be divided into anaerobic layer, aerobic layer, attached water layer and moving water layer from the filter material outward. [0003] The carrier for microbial growth and aggregation (generally called filler) is set in the sewage treatment structure. Under the condition of oxygenation, the microorganisms gather and adhere to the surface of the filler to form a biofilm. After oxygenation (the oxygenation device is composed of a wa...
