| 摘 要： | 目的]探讨土壤微生物降解化工废渣的影响因素及有效措施。方法]在试验区用四分法在地表20cm内取土壤样品,分别测出单位质量的燃烧失重,再向每块试验区施入不同的废渣,每隔5d取样后,测定其燃烧失重,获得各块土壤有机废渣随时间的降解数据。结果]土壤有机废渣的生物降解受废渣性质、废渣表面积、土壤含氧量、土壤pH、含湿量和土壤温度的影响。有机物的好氧降解比厌氧降解快的多,完全的多。土壤pH影响生物的活动,应维持在7～9。土壤含湿量控制50%～60%是微生物活动的最佳条件。土壤温度在零度以下,生物降解基本停止。结论]在实际应用于工业化处理有机废渣时,还需对某种土质和某种废渣作进一步研究,控制生物降解速率和程度及其管理措施。

| Abstract: | Objective] The study aimed to discuss the influencing factors and effective measures for the biological degradation of chemical-industrial waste residue with the soil microbial.Method] In testing area the soil samples were taken from the surface soil in 20cm with quartering method and the burning weightlessness of unit quality was detected resp.,and then the different waste residue was applied into the each experimental plot and the their burning weightlessness were determined after taking the samples in ... |
