Research on the effect of water content and particle size on degradation of organic matter in municipal solid waste

摘要

The water content and particle size are influencing factors on organic matters degradation. According to the component character of Chongqing municipal solid waste, the sample was confected and tested on degradation ratio and degradation speed under different water content and particle size conditions. The results showed that the degradation ratio present rule of Logistic model. Degradation speed first increased and then decreased. The water accelerated the degradation, when the water contents were 50%, the sample was easiest to degradation. The smaller of particle size the easier to degradation.
