Embodiment 1

[0044] like figure 1 Shown, invent a kind of deep bed multiplying MBBR reactor of rural sewage treatment, comprise the anaerobic pond 18, anoxic pond 19, MBBR pond 20, secondary settling pond 21 and micro-ecological filter bed 16 connected successively, described anaerobic The pool 18 is connected to the water inlet pipe 1, the anaerobic pool 18 communicates with the anoxic pool 19 through the pipeline I23, the anoxic pool 19 communicates with the MBBR pool 20 through the pipeline II24, and the MBBR pool 20 communicates with the secondary sedimentation tank 21 through the pipeline III25 , the secondary sedimentation tank 21 is communicated with the micro-ecological filter bed 16 through the secondary sedimentation tank outlet pipe 10, and plants 14 are planted on the micro-ecological filter bed 16;

[0045] Under the action of water pump or gravity, the sewage enters the water inlet pipe 1 and flows into the anaerobic pool 18, and after being treated in the anaerobic pool 18, ...

Embodiment 2

[0056] This embodiment is based on Embodiment 1 to further illustrate the invention.

[0057] like figure 1 As shown, a deep bed multiplying MBBR reactor for rural sewage treatment is invented, which also includes a water collection well 17 communicated with the microbial ecological filter bed 16 through the pipeline IV22, and the water collection well 17 is communicated with the water system.

[0058] The water system sends the qualified water obtained by the sewage treatment system to places where water is needed, such as farmland irrigation or fish ponds.

[0059] Further, a sludge return system is also included, the sludge return system includes a sludge return pump 13 and a sludge return pipeline 5 connected in sequence, one end of the sludge return pipeline 5 is inserted into the bottom of the secondary sedimentation tank 21, The other end of the sludge return pipeline 5 is inserted into the anaerobic tank 18 , and the sludge return pump 13 sends the sludge in the secon...

Embodiment 3

[0062] This embodiment is based on Embodiment 1, and further explains the aeration system.

[0063] like figure 1 As shown, a deep bed multiplication MBBR reactor for rural sewage treatment is invented, which also includes an aeration system. Both are equipped with an aeration branch pipe 12 and an aeration pan 11, the aeration pan 11 is located at the bottom of the pool, one end of the aeration branch pipe 12 is connected to the corresponding aeration pan 11, and the other end of the aeration branch pipe 12 is connected to the aeration main pipe 4 connected, the blower 2 sends air into each aeration branch pipe 12 through the aeration main pipe 4 under the drive of the motor.

[0064] Preferably, the aeration pan 11 is a diaphragm aeration pan.

[0065] The MBBR tank 20 is aerated and oxygenated, and the filler-sewage-air three-phase in the tank is in a fluidized state. The three phases are fully contacted, mixed and collided, and it is easier to form a biofilm on the carri...

Abstract

The invention discloses a deep-bed multiplication MBBR reactor for rural sewage treatment. The deep-bed multiplication MBBR reactor comprises an anaerobic tank, an anoxic tank, an MBBR tank, a secondary sedimentation tank and a micro-ecology filter bed and is characterized in that the anaerobic tank is connected with a water inlet pipe, the anaerobic tank is communicated with the anoxic tank through a pipeline I, the anoxic tank is communicated with the MBBR tank through a pipeline II, the MBBR tank is communicated with the secondary sedimentation tank through a pipeline III, the secondary sedimentation tank is communicated with the micro-ecology filter bed through a secondary sedimentation tank water outlet pipe, and plants are planted on the micro-ecology filter bed; sewage enters the water inlet pipe, flows into the anaerobic tank, is sequentially treated by the anaerobic tank, the anoxic tank, the MBBR tank and the secondary sedimentation tank and then enters the micro-ecology filter bed. The deep-bed multiplication MBBR reactor has the advantages that an aerobic zone is small in floor space, and civil engineering investment is saved; under conditions that same filler is addedand pollution load is identical, the MBBR tank about accounts for 70% of the capacity of a conventional aerobic tank; meanwhile, the MBBR tank is short in starting time, low in operation energy consumption, resistant to impact load, prolonged in sludge age, free of sludge bulking and resistant to toxic compounds.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a deep-bed multiplication MBBR reactor for rural sewage treatment. Background technique [0002] During the development of rural industry and aquaculture, the discharge of production and domestic wastewater and fixed waste increased, the lack of management of drinking water sources, the extensive use of chemical fertilizers and pesticides, the random discharge of livestock and poultry manure, and pollutants from township and township enterprises have negatively impacted rural water bodies. The environment has caused huge pollution. [0003] The research on domestic sewage treatment in rural areas in my country started relatively late, and there are many kinds of processes. Rural sewage has many characteristics such as dispersiveness, large differences in water volume, and relatively low concentration of pollutants. The centralized treatment of rural domestic sewage in mos...
