【正文】 useful materials separated from MSW. The posting process is shown as follows: This is the firststage fermentation This is the second stage fermentation This is the picture of posting process control station Composting quality The posting quality is shown as following Table No item standard Composting production partical power 1 TN， % ≥ 2 TP（ P2O5）， % ≥ 3 TK（ K2O）， % ≥ 4 Organic matter（ C）， % ≥10 5 Moisture content， % 525 6 pH 7 Foreign matters， % ≤3 8 pathogens 101102 101 101 9 TCd， mg/kg ≤3 10 TPb， mg/kg ≤100 11 THg， mg/kg ≤5 12 TCr， mg/kg ≤300 13 TAs， mg/kg ≤30 14 DDT， mg/kg ≤ ≤ The Table indicated that the posting quality of this factory is satisfied with the Composting quality Standard of agriculture Thank you very much 。 is maximum rate of solid substrate hydrolysis which occurs at high microbial concentration。k g) in Run C. However, the peak rate of carbon dioxide only mol/(h（hkg kg and g/hkg and g/hkg and g/h WSi is the sample weight of different time. RESULTS For the emission of outlet gas: ? When aeration flow was L/(min?kg), the moisture of posting matters was around 55%.
