Abstract

In this study, a comparative evaluation of bio-augmentation prospects for the management of Segregated Putrescible Municipal Solid Waste (SPMSW) has been carried out. Six parameters under three heads that are Degradability (TOC%, C: N ratio) Nutrient release efficacy (TKN%, E. C. & TK%), and Change in Medium (pH) were examined and results were further analyzed. In comparison to Seeded Microbial Composting (SMC); the Secondary Decomposer Bio-augmentation (SDB) resulted in a greater rate of TOC% degradation, C: N ratio reduction, rise in availability of TKN%, E. C., and TK%. The value observed at the final day of treatment had remarkable difference (0.05% level of significance). Due course of degradation it was observed that pH was reeling towards neutral range in SDB while to the acidic in SMC. In SDB, priming could be the reason of faster, better, and time-efficient manuring than SMC, which is availed by Secondary decomposers that were boosting the decomposition process. In SDB priming could be the reason which has been availed by secondary decomposers that were boosting the decomposition process which exhibited in the form of faster, better, and time-efficient manuring than SMC.

可腐烂城市固体废物的潜力评估生物增肥前景

在这项研究中，对生物强化在隔离可腐烂城市固体废物（SPMSW）管理中的前景进行了比较评估。考察了三种情况下的六个参数，即可降解性（TOC%、C:N比）、养分释放效率（TKN%、E.C.&TK%）和培养基变化（pH），并对结果进行了进一步分析。与种子微生物堆肥（SMC）相比；二级分解器生物增强（SDB）导致更高的TOC%降解率、C:N比降低、TKN%、E.C.和TK%的可用性增加。在治疗的最后一天观察到的值具有显著差异（0.05%的显著性水平）。在降解过程中，观察到SDB中的pH向中性范围波动，而SMC中的pH则向酸性波动。在SDB中，引发可能是比SMC更快、更好、更省时的施肥的原因，SMC是由促进分解过程的二级分解器提供的。在SDB中，引发可能是二级分解者促进分解过程的原因，二级分解器表现出比SMC更快、更好、更省时的施肥形式。
