本研究的目的是确定CaCN 2 对致病性E的影响。大肠杆菌是一种抗菌剂，及其作为实验室规模堆肥奶牛粪便混合物的改良剂对堆肥进度的影响。评价堆肥63天过程中物理参数、化学参数和生物参数的变化。分析结果表明，在复合稳定基质中添加2%和3% CaCN 2 显着提高了堆肥产品的质量。对大肠杆菌的灭活试验表明，堆肥过程中添加2%和3%的CaCN2显着缩短了大肠杆菌的灭活时间，表明添加CaCN2的堆肥可以很快达到卫生标准。
The objective ofthestudy was to determine the effect of CaCN 2 on pathogenicE. colias an antimicrobial agent and its impact on composting progress as an amendment in dairy cowmanure based mixtures composted at laboratory scale. The changes in physical parameters, chemical parameters and biological parameters during 63 days composting were evaluated. The results of the analysis revealed that additions of 2% and 3% CaCN 2into thecompo stablesubstratesignificantly improved the quality of the composting products. And the test for inactivation of E. colishowed that additions of 2% and 3% CaCN2 significantly shortened the time to inactivate E. coliduring composting, indicating that the composting could quickly reach the sanitary standard withthe addition ofCaCN 2.
