Abstract

The invention provides a household sewage treatment device of a circulating fluidized bed.The household sewage treatment device comprises an anaerobic reaction unit, an aerobic reaction unit and a filtering and precipitating unit.A water inlet is formed in the upper portion of the anaerobic reaction unit, and a stirring air pipe is arranged at the bottom of the anaerobic reaction unit.The aerobic reaction unit is filled with efficient biocompatibility filler.A filter material bearing plate is arranged at the lower portion of the filtering and precipitating unit, and a cover plate is arranged at the upper portion of the filtering and precipitating unit.The space between the filter material bearing plate and the cover plate is filled with a filter material.A water outlet is formed in the upper portion of the filtering and precipitating unit, and the bottom of the anaerobic reaction unit is communicated with the upper area of the filler cover plate of the aerobic reaction unit through a first connecting pipe.The bottom of the aerobic reaction unit is communicated with the lower area of the filter material bearing plate through a second communicating pipe.The upper portion of the anaerobic reaction unit is communicated with the lower area of the filter material bearing plate through a backflow pipe.The household sewage treatment device has the advantages of being high in sewage treatment efficiency, small in occupied area, capable of easily making the sewage treatment result to reach the standards and the like.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a circulating fluidized bed household sewage treatment equipment. Background technique [0002] The research on the application of biological fluidized bed sewage treatment technology to sewage treatment began in the United States in the 1970s. Fluidized bed is a type of reactor that uses the concept of fluidization for mass transfer or heat transfer operation. It is different from the traditional fixed bed reactor. The solid particles in the bed are always suspended in the liquid and move vigorously, which greatly strengthens the diffusion process of the substance, improves the reaction speed, and can increase the amount of liquid reactant that can be processed per unit volume by 2~ 10 times, which enables fluidization to be widely used in industry. [0003] At present, most of the sewage treatment processes are determined according to the water quality conditions. The sewage tr...
