摘要

为寻求经济与环保的方式解决当前城市污泥的排放出路

促进污泥无害化及资源化利用

以期筛选出高效优质的有机肥料配方

并符合现行的有机肥料行业标准NY 525-2002。研究根据污泥的特性和当地条件选择合适的调理剂(如树枝、草炭、糠醛渣、畜禽粪便等)进行配比

通过静态堆置发酵技术

研究污泥堆肥过程中一些理化性质和微生物学特性动态变化。结果表明:经过42d的堆肥发酵

5个处理均达到腐熟

处理2、处理3配方合理

既可更多地消化污泥

又可得到养分含量较高的产品

符合现行的有机肥料行业标准NY 525-2002;堆肥过程中细菌较放线菌和真菌高出2～3个数量级

且细菌增长速度较另外2种菌快

细菌总数在第3天达到最高

真菌和放线菌相对滞后

在第7天总数达到最高

微生物数量的变化也反映着污泥堆肥的腐熟度。

Abstract

In order to seek for the ways of emission of sewage sludge by economic and environmental methods

promote the harmless and resource utilization of sludge

filter out high quality organic fertilizer formula and consistent with industry standards NY 525-2002.Selecting suitable conditioner according to feature of sludge and local condition

the dynamic change of physicochemical properties and microbiological characteristics during the composting process were studied.The results showed that all treatment reached m...
