Abstract:
In order to study the nitrogen translormation and composting period in high temperalure aerobiecomposting of vinasse, an experiment was carried out on the condiion of an open environment and natural ven-tilation, which is expeeted to provide seientilie basis and technieal guidanee for vinasse resouree utilization.results showed that: in the 28-day process of composting, temperalure reached 50 on the seventh day, thetemperature above 50 9 lasted 10 days; the content of NH4+-N ollered upgrade firstly and then deseendinglatter tendeney. Until the end of composting, the content of NH3- -N inereased by 82.0%. The content tend.eney of NO4+-N was eontrary to NH3--N and NO,-N content was redueed by 44.5%6 compared with theinitial stage. The content of Org-N and ’T’N had the same variation trend, olered upgrade firstly and then deseending later tendeney. Until the end of composing, the contents of Org-N and TN were 17.19% and 1.9%higher than initial stage respectively. On the 28th day, germination index reached 90.4%6 , compost maturityfully met the requirements. In consideration of the change of temperature and pH in the proeess of composting,it can be concluded that the period of vinasse compost is 22 days on the condition of open environment, naturalventilation and once artifieial turning every 3 days.
