华南地区低有机质污泥碱性厌氧产酸（VFAs）性能机理与菌群分析
Mechanism and microbial community analysis of anaerobic acid production (VFAs) by low carbon sludge in South China at alkaline condition
摘要
Abstract
Nowadays, the researches of VFAs production by excess sludge focused mainly on the utilization of the excess sludge from wastewater treatment plant (WWTP) in east and north areas of China, and few on the sludge in south China. Meanwhile, the related on-site experimental research for VFAs production property by sludge from WWTP in south China was rarely reported. Research on VFAs production by excess sludge was conducted at alkaline condition by semi-continuous anaerobic reactor, which was located at Dinghu wastewater treatment plant in Zhaoqing, Guangdong Province. The results showed that great hydrolysis and acidification properties of the system could be achieved at alkaline condition (pH=10.0). The percentage of VFAs-COD/SCOD was 73.89% in average, which was about 2%—15% higher than that of existing similar researches. Meanwhile, only small amount of polysaccharide and protein were accumulated (5%—15% of SCOD). Acetic acid was the main component of VFAs with the proportion of 51.43%. And the dominant microbial species in the system were all nearly acid production microorganisms includingAcetoanaerobiumsp., Clostridiales bacteriumZ-810,Proteinivorax tanatarensestrainZ-910 andTissierellasp.,amongwhichAcetoanaerobiumsp. andClostridiales bacterium Z-810 were not reported in other similar researches. The excess sludge reduction rate of 33.5% could be achieved.关键词
