Method for high-temperature anaerobic treatment on cassava alcohol waste liquor by different inocula

Abstract

The invention discloses a method for high-temperature anaerobic treatment on cassava alcohol waste liquor by different inocula, and belongs to the technical fields of high-concentration organic wastewater treatment control and environment-friendly purification treatment. The method is characterized in that the high-concentration organic wastewater is treated by different inocula through anaerobic fermentation, the fermenting characteristics are analyzed to understand the relationship between the anaerobic fermenting metabolite of the different inocula and key enzyme activity, the reliable guidance is provided for the actual cassava alcohol waste liquor treatment process, and a new concept is provided to find the proper inoculated sludge; a large amount of marsh gas can be produced in the anaerobic fermentation process, the cassava alcohol waste liquor is effectively treated, and the harmless, reduction and resource effects of the high-concentration organic wastewater are realized. The method has the advantages that the method is simple, the operation is easy, the stability is high, and the fermenting characteristics of different inoculated sludge on the cassava alcohol waste liquor treatment can be effectively evaluated.

Description

technical field [0001] The invention relates to a method for high-temperature anaerobic treatment of cassava alcohol waste liquid by different inoculum, and belongs to the technical fields of high-concentration organic wastewater treatment control and environmental protection purification treatment. Background technique [0002] In recent years, with the acceleration of China's economic development, fossil fuels such as petroleum and coal have been continuously consumed and reduced, and have caused serious and potential ecological environment damage, resulting in excessive energy consumption and a serious decline in environmental quality. Therefore, in order to To alleviate the shortage of resources, ensure energy security and environmental health, my country attaches great importance to the development of diversified alternative renewable energy sources. Cassava is one of the three largest potato crops in the world. Its output is second only to potatoes. Its roots and stems ...
