生活垃圾处理机中复合微生物降解厨余垃圾的机理研究

为探究复合微生物降解厨余垃圾的机理,通过采用复合微生物降解各类厨余垃圾的降解温度、代谢气体成分以及对残余代谢物中的氮及磷含量的分析,得出复合微生物降解生活垃圾的温度在高温期稳定在48~52℃,有利于杀灭垃圾中的病原菌;微生物降解过程中排放的气体主要成分为CH_4、CO_2、H_2S、NH_3等,是垃圾减量化的主要原因之一;降解产物中富含氮和磷速效成分,可作为肥料使用。

MECHANISM STUDY ON DEGRADATION OF KITCHEN WASTE BY COMPOUND MICROORGANISM IN A DOMESTIC GARBAGE PROCESSOR

This paper aimed to explore the mechanism of composite microbial degradation of kitchen waste,by analysis on degradation temperature of all kinds of solid waste,metabolic gas composition and nitrogen and phosphorus content in residual metabolites.It drew the conclusion as follows:The temperature of composite microbial degradation with domestic rubbish stayed 48 ～ 52 ℃ in high temperature period,and that's sufficient to kill pathogenic bacteria in the garbage;the content of the gases emitted in biodegradation process was mainly CH4 、CO2 、H2S,and NH3,which is the main reason of waste volume reduction;the metabolites residual was rich in nutrient factors like nitrogen and phosphorus and fit for being raw material of fertilizer.
