温度和pH值对餐厨垃圾和牛粪混合厌氧发酵的影响
Effects of temperature and pH value on anaerobic fermentation with mixed material of restaurant garbage and cow dung
摘要
Abstract
In order to provide scientific basis for restaurant garbage resource utilization,through sequencing batch, the gas production,the methane produnction,the change of pH value in the fermentation and the removal rate of organic matter were taken as index.The effects of temperature and initial pH value to the anaerobic fermentation with kitchen garbage and cow dung was studdied. The test results showed that anaerobic fermentation effect was the best when temperature was 50℃. At this time,the unnit gas production was 722.98 mL/gVS,the methane volume fraction was up to 62.73%, the removal rate of organic matter was 67.5%. When the initial pH value was 7, anaerobic fermentation effect was the best.At this time,the unit gas production was 618.23 mL/gVS, methane volume fraction was up to 62.4%, the removal rate of organic matter was 66%.关键词
