Problems solved by technology

[0005] (1) A single SBR reactor requires a larger regulating tank
[0006] (2) When the amount of treated water is large, the problem of mismatch between incoming water and intermittent incoming water is difficult to solve
At this time, multiple sets of SBR reactors need to be operated in parallel, the valves are switched frequently, and the operation procedures are complicated
[0007] (3) When there is a large amount of water, the advantage is not obvious
[0008] (4) High equipment idle rate
[0009] (5) The resistance loss of sewage lifting is relatively large

Embodiment 1

[0054] A composite HBF module reactor of this embodiment includes an anaerobic tank, an anoxic tank, an aerobic tank, and an SBR tank that are sequentially connected; wherein the SBR tank includes a first SBR tank and a second SBR tank, The first SBR tank and the second SBR tank are simultaneously connected with the aerobic tank, and the aerobic tank, the first SBR tank and the second SBR tank are respectively provided with enzyme floating fillers.

[0055] Specifically, the enzyme floating filler described in this embodiment can be manufactured by using the announcement number CN101633529B and the name is "Method for Manufacturing Ionic Enzymatic Suspended Filling Applied to Treatment of Highly Difficult Wastewater" (hereinafter referred to as the announcement document).

[0056] Exemplarily, the enzyme floating filler used in this embodiment is made according to the teaching in the announcement document with the announcement number CN101633529B, specifically using the method taugh...

Embodiment 2

[0068] Picture 12 Flow chart of sewage treatment process. This embodiment proposes a sewage treatment process using the composite HBF module reactor of the first embodiment, and the components are assembled and connected according to the description of the first embodiment to form a figure 1 with figure 2 The composite HBF modular reactor shown, combined with Picture 12 As shown, perform the following steps in sequence:

[0069] Step S1: The sewage is introduced into the anaerobic zone 5 of the anaerobic and anoxic module 1 through the sewage inlet pipe, and is stirred and mixed with the sludge conveyed by the sludge return device 10 in the anaerobic zone 5 to complete the anaerobic release phosphorus. Exemplarily, a submersible mixer is built in the anaerobic zone 5 for mixing.

[0070] Step S2: The sewage in the anaerobic zone 5 is introduced into the anoxic zone 6, and mixed with the liquid returned by the nitrification liquid reflux pump 7, while adding nitrate nitrogen for...

Abstract

The invention discloses a composite HBF (Honess Hybrid Biological&Fixed film Technology) module reactor which comprises an anaerobic pool, an anoxic pool, an aerobiotic pool and an SBR (Sequencing Batch Reactor) pool, wherein the SBR pool comprises a first SBR pool and a second SBR pool which are connected with the aerobiotic pool at the same time. The aerobiotic pool, the first SBR pool and the second SBR pool are internally provided with enzyme floating fillers, respectively. The anaerobic pool, the anoxic pool, the aerobiotic pool, the first SBR pool and the second SBR pool are module members. The invention further provides a sewage treatment process. Based on AAO-SBR (Anaerobic-Anoxic-Oxic-Sequencing Batch Reactor), the aerobiotic pool, the first SBR pool and the second SBR pool are internally provided with enzyme floating fillers respectively as biological attaching carriers, so that the biomass of the reactor is more than 2 times of that by an activated sludge process in volume, thereby greatly enhancing the processing capacity of the reactor and simplifying the structure of the reactor.

Description

Technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a composite HBF module reactor and a sewage treatment process. Background technique [0002] The national "Twelfth Five-Year Plan" has formulated a strategic policy to vigorously promote urbanization and accelerate the overall economic and social development of cities and towns. Environmental protection has always been the top priority of urbanization. However, due to limited technical capabilities, high investment costs, and failure to achieve the expected results, serious environmental pollution problems have appeared in the process of urbanization, especially related to daily life. The inseparable sewage treatment problem. [0003] Sequencing Batch Reactor (SBR), also known as Sequencing Batch Reactor, is a wastewater treatment process different from traditional activated sludge. As the SBR is in operation, the operating time of each stage, the change in the volume of the ...
