Biological activity was most intensive in Run C and was least intensive in the control run. ?The concentration of H2S in control run was high during posting processes. ?The maximal emissions of H2S were mg/L in the control run, mg/L in run A, mg/L in run B, and mg/L in run C ?Therefore, inoculation is useful for controlling H2Semission. 67891011121314150 20 40 60 80 100 120 140C o m p o s t i n g T i m e /hLogCFU/gControlRun ARun BRun CThe following figure shows the total heterotroph counts profile in the posting process For the total heterotroph counts: ?

However, traditional posting method wholly relies on its initial microbial munity, problems such as relatively long retention time, odor emissions and poor post quality may e out. ? To improve the above pitfalls, various specialized seed inoculums have been applied. ? Sometimes, high concentration of indigenous microanisms can inhibit the prevalence of inoculated ones ? Thus, an inoculation method that can effectively control the indigenous cell concentration is highly desired. ? The inoculated microbial populations and munity positions would keep evolving incessantly, leading to variations among different posting stages ? To well understand inoculation posting process, it is necessary to divide the posting processes into multiple stages ? However, most of the existing systems seldom considered the various stages of inoculation posting processes. This leads to difficulties in determining the efficiency of inoculation. OBJECTIVE ? The objective of this study is to develop a new inoculat
