Orthogonal experiment of anaerobic methane fermentation of water hyacinth

Fresh hyacinth is an appropriate kind raw material of anaerobic methane fermentation.Feed rates,the initial pH value,temperature,C/N were selected to carry on orthogonal experiments which were four factors and three levels,with the purpose of gaining the impact results of these factors.The results showed that Anaerobic fermentation of water hyacinth was a medium-temperature fermentation process which high temperature would damage the reaction,Weak alkaline pH value was conducive to improving the gas production rate,but the effects of different C/N was not obvious.
