摘要：

In an effort to improve the anaerobic digestion process of water hyacinth-cattle dung, the effects of various doses of different surfactants: Tween 20, Tween 60, Tween 80, sodium lauryl sulphate, Tegoprens 42, Tegoprens 43, Tegoprens 47, Tegoprens 51, Tegoprens 52, Tegoprens 63, have been evaluated in bench-scale digesters. Increasing concentrations of surfactants produced maxima or minima in the various parameters measured. Amongst the surfactants tested, Tegoprens 43 showed a maximum of more than 114% increase in gas production with a 6.25% higher methane content.
