Abstract

Sewage sludge could not compost successfully because of low organic matter.Straw was translated into external carbon source after decomposing and added into low organic sludge with the ration of 1:6.Aerobic composting was carried out after the mix at the condition of forced ventilation.Composing of low organic sludge could rise to 55 ℃ and lasted for over 3 days without pollution.Through comparative experiment after decomposing,it was proved that it had good effect using as organic fertilizer.
