Embodiment 1

[0045] A carrier fluidized MBBR moving bed biofilm reactor, such as figure 1 As shown, it mainly includes a plurality of reactors 1 and an annular water injection pipe 7. The plurality of reactors 1 are divided into a central reactor 1 and an outer reactor 1. There are 6 outer reactors 1 surrounding the center. On the outside of the 16 edges of the reactor, each outer reactor 1 is connected to the reactor 1 at the center through a joint 8, and the annular water injection pipe 7 is arranged above the reactor 1, and is connected to each outer reactor 1 through a water injection connecting pipe 71. The reactor 1 is connected, and the annular water injection pipe 7 is provided with a water injection main port 72;

[0046] like figure 2 As shown, the reactor 1 is in the shape of a hexagonal prism, and the center of its upper top surface is provided with an insertion hole 19, and each edge of the upper surface of the reactor 1 is respectively provided with a water injection port 1...

Embodiment 2

[0062] Embodiment 2 is basically the same as Embodiment 1, the difference is that, as Figure 12 As shown, the MBBR moving bed biofilm reactor mainly includes three reactors 1, and the three reactors 1 are sequentially connected in series through joints 8.

[0063] At the same time, other different assembly methods can also be carried out according to terrain needs and the like.

experiment example 1

[0068] Experimental Example 1: After being treated by the device and process of Experimental Example 1, the chromaticity of the effluent is 19 times, COD 110mg / L, SS<70mg / L; at the same time, there is no clogging during the whole process of the device, and the total treatment efficiency is compared with that of the opposite Ratio increased by 29%;

Abstract

The invention discloses a carrier fluidized MBBR moving bed biofilm reactor and its technology, which includes a plurality of reactors and annular water injection pipes. There is a ring of aeration device 1 around the outer circumference of the pedestal. The inner wall of the reactor is provided with a water distribution ring pipe, which is connected to each water injection port through the water distribution connection pipe. The upper right side of the reactor is provided with a water outlet; There are reaction plug-in components, and the reaction plug-in components include carrier plates, inner ring plates, pedestal docking plates, center columns, and center carrier plates; deflectors are respectively provided in the reactor and each facet, and the deflectors are connected by connecting The rod is connected with the outer wall of the inner ring plate, an adjustment shaft is provided at the connection between the deflector and the connecting rod, and two adjacent deflectors are respectively connected by water-proof cloth. The invention has the advantages of convenient disassembly and assembly, small occupied area, efficient and rapid treatment, and high purification efficiency.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a carrier fluidized MBBR moving bed biofilm reactor and a process. Background technique [0002] The moving bed biofilm reactor is a new type of biofilm reactor, which is an improved new composite biofilm reactor developed on the basis of fixed bed reactor, fluidized bed reactor and biofilter. It overcomes the need for regular backwashing in fixed bed reactors, the need to fluidize the carrier in fluidized bed reactors, and the complex operations of cleaning filter materials and replacing aerators in submerged biofilters, and retains the traditional biofilm It has the characteristics of anti-shock load, less sludge output and long sludge age. Compared with the activated sludge method, due to the longer sludge age, more nitrifying bacteria can be maintained, and it has a better denitrification effect. The main principle is to use the sewage to continuously flow through ...
