Experimental Study of the Coproduction Technology of Straw and Excrement Ferment for Biogas and Organic Compound Fertilizer

Abstract:

This paper used respective ratios of 50%, 60%, 70%, 80%, 90% and 100% of straw and pig excrement as raw materials to produce biogas and fertilizer. The test focused on gas production, the contents of available nutritional elements nitrogen, phosphorus and potassium, and the organic matter content. The experimental results demonstrate the fermentation can produce more biogas, nitrogen, phosphorus, potassium, and organic mass under the conditions which the fermentation cycle is 15 days and the ratio of straw and excrement is 70%.
