Method for enhancing mixed fermentation of kitchen garbage through deamination of black water

The invention provides a method for enhancing mixed fermentation of kitchen garbage through black water deamination, namely ammonia nitrogen in black water is removed by using a steam stripping device, and the deaminated black water and the kitchen garbage are subjected to mixed fermentation. On the basis of relieving acid inhibition and ammonia inhibition of independent fermentation of the kitchen garbage and the black water, the mixed fermentation performance of the two organic matters is further improved, the methane production efficiency is remarkably improved, and the method is safe and stable in operation and low in cost. And the method has important significance on energy resource utilization of two high-concentration household organic waste flows, namely kitchen garbage and black water, under rural scattered conditions. 本发明提供一种黑水脱氨强化厨余垃圾混合发酵的方法，即利用蒸汽吹脱装置脱除黑水中的氨氮，脱氨后的黑水与厨余垃圾进行混合发酵。本发明能够在缓解厨余垃圾和黑水单独发酵酸抑制和氨抑制的基础上，进一步提高两种有机物的混合发酵性能，显著提升产甲烷效率，且运行安全稳定，对于农村分散条件下厨余垃圾和黑水两种高浓度家庭有机废物流的能源资源化具有重要意义。
