Screening of food waste biodegradation bacteria and optimization of inoculation methods
Due to high moisture and organic matter content,improper disposal of food waste can easily cause environmental pollution.Biodegradation can effectively reduce the moisture and organic matter in food waste,reduce the pressure of post-disposal,and achieve the purpose of minimization.In order to further improve the efficiency of food waste biodegradation,by studying the growth characteristics of bacteria and single-bacterial biodegradation experiment of food waste,4 strains of highly efficient degrading bacteria were screened from the existing 10 in the laboratory to produce a compound bacterial agent,which was added into the autothermal degradation system of food waste through bio-augmentation,so that the high-temperature period could be reached 1d earlier,and the volatile solids removal rate was increased by 6.72%—25.82%.Moreover,the reaction process was further accelerated by staged inoculation of bacteria,with a 3.87%increase in VSR compared with one-time inoculation method,which proved that the staged inoculation of bacterial method was more suitable for the autothermal degradation of food waste.
