Abstract

Every year organic liquids from food industry and agriculture are disposed to rivers or environments without or with little treatment. The pollution causes magnitude direct and indirect harm to people. Compared with traditional high strength liquid treating techniques, there are a series of advantages in utilizing thermophilic bacteria processing: (1)more rapid bio-degradation, the microorganisms with higher activity and metabolismat high temperature; (2)higher wastewater treating rate; (3)lower concentration of residual bio-solids; (4)effective killing of pathogen. But the high temperature changes the liquid’s biological and bio-chemical characters, all of which make it more complex for treatment. Thermophilic bacteria and its thermotolerant mechanism, advantages and disadvantages, kinetics equation are demonstrated. Some example for treating high temperature liquid are listed. A preliminary discussion is given to its wide prospect.
