Method and device for processing sewage by virtue of multistage alternative microbial generator

Abstract

The invention discloses a method and device for processing sewage by virtue of a multistage alternative microbial generator. The method comprises the following steps: alternatively operating at least one-stage optimal three-stage microbial generation system, a biological generator group A and a biological generator group B, deriving step by step and logarithmically growing. The three-stage microbial generation system comprises an I-stage microbial generation system, a (img file='2014100613797100004dest-path-image001.TIF'wi='17'he='16'/)-stage microbial generation system and a (img file='559932dest-path-image002.TIF'wi=27'he='17'/)-stage microbial generation system. Each microbial generation system comprises a biological generator group A and a biological generator group B; the alternative operation of the biological generator group A and the biological generator group B comprises the processes of enabling the biological generator group B to have a rest for being needed again when the biological generator group A works normally; enabling the biological generator group A to have a rest for being needed again when the biological generator group B works normally. The step of deriving step by step comprises a process of taking a strain to simulate water temperature, climate, water quality and load in the I-stage microbial generation system, the (img file='2014100613797100004dest-path-image001.TIF'wi='17'he='16'/)-stage microbial generation system and the (img file='559932dest-path-image002.TIF'wi=27'he='17'/)-stage microbial generation system, then enabling microorganism to logarithmically grow in a special environment domestication and accelerating to generate microbial species. The method and the device for processing sewage through the multistage alternative microbial generator are good in processing effect and capable of greatly reducing sludge amount in the sewage treatment.
