The digestion of baker’s yeast wastewater was monitored by gas production intensity and composition of gaseous and liquid phases. Favorable coexistence of sulfate reducing bacteria and methanogens was explained by the presence and metabolism of trimethylamine, a degradation product of betaine. Concentration of sulfides decreased at the expense of betaine degradation with final products S0 and N2. Since biological wastewater treatment was complicated by both high content of SO42-, eventually becoming reduced to toxic H2S, and high total nitrogen content, a technological solution that links sulfate reduction to elemental sulfur coupled with reactions producing gaseous nitrogen may have great practical value. 相似文献

Microcalorimetric Monitoring of Anaerobic Digestion Processes 总被引:2,自引:0,他引:2

Microcalorimetry was used for monitoring anaerobic digestion processes of heavily polluted industrial waste waters (from cheese
industry, distilleries, yeast plant). Interpreting the thermal power-time curves by HPLC, some sub-processes in batch cultures
were tentatively identified as acidogenic, acetogenic and methanogenic. Processes underlying power-time curves up to 10 h
were different for different wastes. In the case of cheese whey and distillery waste it was acidogenesis, in the case of sulfate
containing waste - presumably reduction of sulfates. The effect of Biotreat 100 (BimKemi Eesti Ltd.), a preparation for removing
H2S from waste water, was observed for these processes.
