compost stabilization process - Opis:
- This study presented investigation results of temperature and organic master changes during two stages composting process. The feedstock components were dewaterednot digested sewage sludge and rape straw as a structural material. The aim of investigation concerned determination of relationship between time of composting duration in rotating rector (125 m3 volume) and time of stabilization of compost in periodically browsed windrows. Five cycles with different time of feedstock retention were monitored: 7, 10, 14, 18 and 21 days. The second stage of composting in all cycles lasted five months. The results show that longer compost retention in reactor effectively reduce time needed for compost stabilization. Results presented in this paper are a part of investigations which have on aim determination of relationship between duration time of two phases of composting in two stage systems. Changes of both, temperature and content of organic substances durin the process, are one of many parameters which describe process of compost stabilisation [3, 6, 7]. Conducted analysis of achieved results allows to state that longer retention time of feedstock in the reactor causes shorter period of stabilisation. The basis of such conclusion is character of changes of determined physical parameters and interpretation of calculated gradients of organic substances. Changes of both parameters were interpreter in the context of compost stability, which is not synonymous with achieving its maturity. It is hard to conclude, that 37 days of composting, with assumption of 21 days of retention of feedstock in the reactor (fig. 1 - 21 days cycle), assures gaining mature compost. In this regard examinations also included determinations of other physicochemical parameters, including so-called humification index. Those results will be the content of next papers in the Annual Set of Environment Protection.
