Highly efficient water treatment method by aerobic circulating biological expansion bed and reactor thereof

Abstract

The high-efficiency water treatment method for aerobic cycle biological expansion bed comprises: using the distribution gas device on reaction tower bottom and light biological particle of aerobic bed to take water treatment to biological reaction with aerobic biological reaction tower as main; and controlling the flow rising speed in tower to achieve need expansion state. The opposite reactor comprises a biological reaction unit, a water cycle unit with a collection pond for output water and cycle pump, an aerobic bed unit. The advantages of this invention include: high organic load, short startup period and stable running.

Description

technical field

[0001] The invention relates to an aerobic biological treatment method and equipment for organic waste water, in particular to a water treatment method and a reactor of a high-efficiency aerobic circulating biological expanded bed, in particular to an aerobic biological reactor of an expanded bed of a biological particle carrier. Background technique

[0002] High-efficiency aerobic bioreactors must have the following characteristics: ①Maximize the concentration of active organisms per unit volume; ②The contact area between sewage and biofilm should be large to make full use of the effective space; ③Between sewage and biofilm The relative motion speed should be large to enhance mass transfer; ④The remaining biofilm is easy to peel off, which can effectively and reliably control the growth of microbial biomass; ⑤It has a strong oxygenation capacity.

[0003] The biological fluidized bed is filled with small inert particles such as s...
