【正文】 ? additionally, inoculation plex microanisms which have high bioactivity for deposing anic matter could enhance maximum degradation rates ? Another function of inoculation was avoiding the lag periods of traditional posting processes. Analysis ?The degradation rate of inoculation posting will not be limited by substrates in the first stage of posting. ?However, with the posting processes undergoing, the solubilization of the solid waste will bee lower and lower, and may bee a significant factor that limits the reaction rate during the second posting stage ?seed inoculum which contain easily biodegradation anic substrates microanisms is necessary to avoid deposition limitation, emission odour gas and make the posting more stable. ? The inoculum inculde: Bacillus azotofixams, Bacillus megaterium Bacillus mucilaginosus, Cellulolytic strains and Whiterot fungi CONCLUSIONS ?The initial cell concentration of indigenous is a key factor for a successful inoculation system. ?A new posting technology (TGTCT) was developed and verified, which could enhance the posting rate, control emission of odour gas and made the posting more stable. ? In the first stage, the deposition rate of Run C was times higher than in noninoculation system Control run. ? In the second stage, inoculation could reduce the value of the half velocity coefficient, make the posting products more stable and improve the posting quality. ? Thus, seed inoculum C is necessary to enhance the efficiency of posting. 1000T/d posting factory of Shanghai in China Composting Site in the Pudong Area The following is the posting program PreSeperation system Firststage fermentation Secondary fermentation Separation system Composting production treatment Water t/d Water Water Water t/d Water t/d Secondary ferment Subsequent treatment product impurity Volatile and water lost Adding water120t/d Large waste : 25t/d , plastic 12t/. 5t/d,dust5t/d , total water contained l10t/d plastic 55 t/d metals bomboo and wood t/d cloth t/d paper7t/d tile 12 t/d glass 40 t/d MSW 1000t/d( water 500t/d) Accepted tank Preseperation Primary ferment Separate system Leachate collecting 20t/d Volatile and water lost Leachate collecting 80t/d Leachate collecting 100t/d t/d,Moisture The following figure shows the substrate and water balance These pictures show the equipments for waste sorting and separation These are
