Problems solved by technology

[0004] The above content shows a scheme of applying MBBR technology for sewage treatment. It adds a layer of blocking net to the MBBR tank to make the filler distribution more uniform and facilitate the reaction of microorganisms in the reactor. However, it is applied to the daily sewage treatment capacity In the environment of 10,000 tons, MBBR fillers are widely distributed and placed in a large amount, resulting in poor use effect and interference with sewage treatment capacity, so a new solution needs to be proposed to solve this problem

Embodiment 1

[0040] On-site adaptive MBBR processing device, refer to figure 1 and figure 2 , including a box body 1, an aeration device 2 and an aeration guide device 3 installed in the box body 1, wherein the box body 1 can be welded (riveted) on-site by carbon steel, taking a rectangular parallelepiped box body as an example, the inside The cavity is an upper opening structure. A water inlet pipe 11 communicating with the inner cavity is fixed on one side of the box body 1, and a water outlet pipe 12 communicating with the inner cavity is fixed on the upper part of the opposite side of the box wall; the lower box wall of the box body 1 is also fixed with a The emptying pipe 13 communicated with it.

[0041] refer to figure 2 and image 3 , the aeration device 2 includes a plurality of gas pipelines 21 evenly laid on the inner bottom surface of the box body 1 and fixed, and a plurality of aeration disks 22 are uniformly installed on the gas pipeline 21; the size of the box body 1 i...

Embodiment 2

[0053] On-site adaptive MBBR processing device, refer to figure 1 , the difference from Embodiment 1 is that it also includes a water quality detection device 7 and an on-site control device 8, wherein the water quality detection device 7 can choose an ammonia nitrogen online analyzer, and its sampling end (probe) is placed at the inlet of the outlet pipe 12 of the box body 1. water end side.

[0054] A filter plate 15 is fixed around the water inlet side of the outlet pipe 12 in the casing 1 , and the aperture on the filter plate 15 is smaller than the size of the MBBR filler to prevent the MBBR filler from breaking away from the casing 1 . The sampling end of the ammonia nitrogen online analyzer can be placed in a cavity surrounded by a plurality of filter plates 15 .

[0055] refer to Figure 6 , the on-site control device 8 includes a PLC controller 81, and the electrical signal of the PLC controller 81 is connected to the output end of the ammonia nitrogen online analyz...

Embodiment 3

[0058] Sewage treatment methods using on-site self-adaptive MBBR treatment devices, including:

[0059] Step 1. Water intake, which includes installing and constructing a sewage pumping device to pump sewage to be treated from a designated area (river channel); the sewage pumping device includes a lift pump, and three lift pumps can be selected, of which two are used normally and one is used as a backup.

[0060] Step 2, primary sedimentation, which includes the construction of a primary sedimentation tank to receive the sewage pumped by the lift pump; the sewage is sanded in the primary sedimentation tank; a float level controller can be installed in the primary sedimentation tank and coupled with the lift pump Linkage, so that when the liquid level reaches a certain set height, the lift pump will be automatically stopped.

[0061] Step 3, biochemical treatment, which includes building an on-site self-adaptive MBBR treatment device, introducing the sewage after the initial pr...

Abstract

The invention discloses an on-site self-adaptive MBBR treatment device and a sewage treatment method applying the same, and relates to the technical field of water quality purification; key points ofthe technical scheme comprise that the on-site self-adaptive MBBR treatment device comprises a tank body and an aeration device arranged in the tank body; a plurality of groups of aeration guide devices are arranged in the tank body; each aeration guide device comprises two inclined guide plates; one end of each inclined guide plate inclines downwards; the upper ends of the two inclined guide plates are opposite to each other; MBBR packing passes through the space between the upper ends of the inclined guide plates and the liquid level; a guide cavity is formed between the two inclined guide plates, backflow cavities are formed between the sides, deviating from each other, of the two inclined guide plates and the inner wall of the box body respectively, and the aeration device comprises aplurality of gas conveying pipelines laid at the inner bottom of the box body, a plurality of aeration discs arranged on the gas conveying pipelines and a draught fan used for supplying gas to the gasconveying pipelines. According to the invention, the application effect of the MBBR technology can be improved, so that the sewage treatment capacity is improved.

Description

technical field [0001] The invention relates to the technical field of water quality purification, more specifically, it relates to an on-site adaptive MBBR treatment device and a sewage treatment method using the same. Background technique [0002] In order to meet the needs of social development and corresponding policies, urban sewage needs to be treated. Currently, there are a variety of urban sewage treatment processes on the market, some of which use MBBR biological processes. In the process of applying MBBR technology, with the increase of the daily sewage treatment capacity, the biggest problem is the use effect of the filler, which has a great impact on the entire sewage treatment process. [0003] The patent with the notification number CN208561833U-an integrated MBBR sewage treatment equipment, its technical points are: including the pool body, the pool body is provided with a partition, and the partition board divides the inner cavity of the pool body into an MB...
