Abstract

Abstract:

The metabolic characteristics of sulfate reducing bacteria and heterotrophic nitrification bacteria in the cooling tower sludge of a thermal power plant have been studied. The corrosion behavior of 304 stainless steel under the combined action of sulfate reducing bacteria and nitrification bacteria is analyzed by surface analysis technique,corrosion weightlessness method and electrochemical technique. The results show that biofilm under the action of mixed bacteria is formed evenly on the surface of 304 stainless steel. Its corrosion rate is less than that under the action of single bacteria.

Key words: microbiologically influenced corrosion, sulfate reducing bacteria, heterotrophic nitrification bacteria
