Embodiment 1

[0034] refer to Figure 1-3 , a kind of A provided by this embodiment 3 / O-MBBR integrated sewage treatment device, including pre-denitrification tank 110, anaerobic tank 120, anoxic tank 130, aerobic tank 140, sedimentation tank 150 and clean water tank 160 connected in sequence, as well as equipment room 170 and sludge return mechanism, nitrification liquid return mechanism, anaerobic liquid return mechanism, ultraviolet sterilizer and fan.

[0035]The water outlets and water inlets of the pre-denitration pond 110, the anaerobic pond 120, the anoxic pond 130 and the aerobic pond 140 are all diagonally arranged in the vertical direction (as the water inlet of the pre-denitration pond 110 is located in such as figure 1 The shown pre-denitration pool 110 is above the pool wall in the upper right corner, and the water outlet is located under the pool wall in the lower left corner of the pre-denitration pool 110, and so on for the other three pool bodies). The water outlet and ...

Embodiment 2

[0046] refer to Figure 4 , a kind of A provided by this embodiment 3 / O-MBBR integrated sewage treatment plant, its structure and the A described in embodiment 1 3 / O-MBBR integrated sewage treatment device is basically the same, the difference is: the anoxic pool in the embodiment 1 is divided into two, that is, the anoxic pool is separated into the first anoxic pool 231 and the first anoxic pool 231 with a partition in the middle. The second anoxic pool 232 . A communicating port is set at the upper left corner of the dividing plate, and a water pipe connected with the water inlet of the first anoxic pond 231 is set in the first anoxic pond 231, and this water pipe stretches to such as Figure 4 The bottom of the tank body in the lower right corner of the first anoxic pool 231 is shown so that the water inlet position and the water outlet position in the first anoxic pool 231 are arranged diagonally in the vertical direction.

Abstract

The invention relates to the technical field of sewage treatment and particularly relates to an A3 / O-MBBR (Moving Bed Biofilm Reactor) integrated sewage treatment device and an A3 / O-MBBR integrated sewage treatment method. According to the device provided by the invention, a sewage backflow mechanism, a nitrification liquor backflow mechanism and an anaerobic liquor backflow mechanism are arranged and suspended filler is filled in an aerobic tank, so that the integrated sewage treatment device has a good effect for treating nitrogen and phosphorus in sewage and is high in treatment efficiency, compact in structure and small in occupied area. In addition, by virtue of optimizing a settling pond structure in the integrated sewage treatment device, the settling effect of the settling pond is improved, and the sludge floatation phenomenon and the content of suspended solids in effluent can be remarkably reduced. After sewage is treated by the integrated sewage treatment device provided by the invention, the effluent can reach the level A of first class stand of pollution discharge standard for municipal sewage treatment plant (GB18918-2002).

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an A 3 / O-MBBR integrated sewage treatment device and sewage treatment method. Background technique [0002] With the development of my country's economy and society, the crisis of water resources and the pollution of the water environment are intensifying, and the discharge of various sewage / wastewater has increased significantly, which seriously threatens the water environment and has become one of the hot spots in the field of environmental protection at home and abroad. Since the "Twelfth Five-Year Plan", the state has intensively issued a number of environmental protection and governance related policies, and its focus has gradually shifted from industrial and urban pollution control to comprehensive environmental management in villages and towns. Village and town sewage treatment has become an environmental protection problem that needs to be solved urgently. Comb...
