摘要
为了实现畜禽粪便的无害化处理及资源化利用,以新鲜牛粪和木屑作为堆料,采用微型试管堆肥法,模拟研究了好氧和厌氧2种堆肥方式下不同堆肥温度(38、50、70℃)对黄体酮、雄烯二酮、17β-雌二醇、雌酮4种天然类固醇激素降解的影响。结果表明,不同温度条件下4种激素在2种堆肥方式下的去除率介于67.6%~100%,其中50℃下的去除率为81.9%~100%。4种激素中,雌酮和雄烯二酮在好氧堆肥方式下的去除率优于厌氧堆肥。试验温度(38~70℃)对17β-雌二醇、黄体酮和雄烯二酮在牛粪堆肥中的降解影响很小,而在70℃的高温堆肥条件下,雌酮的降解受到抑制。在保证堆肥腐熟、杀死有害微生物的前提下,50℃下好氧堆肥效果最佳。
In order to achieve the innocuous treatment and resource utilization of livestock manure,fresh cow dung and straw were used as pile materials. Four types of hormone( progesterone,androstenedione,17β-estradiol and estrone) were incubated in cow dung under different temperature( 38,50,70 ℃) to study the influence of composting temperature on the degradation rate of 4 hormones under either aerobic or anaerobic composting conditions. It was shown that the degradation rate of 4 hormones ranged from 67. 6% to 100% under different temperature,and the degradation rate ranged from 81. 9% to 100% at 50 ℃. The degradation rate of estrone and androstenedione were higher under aerobic composting than that under anaerobic composting. The tested temperature( 38-70 ℃) had little effect on degradation of 17β-estradiol,progesterone and androstenedione in cow dung. But,the degradation of estrone was inhibited under 70 ℃. Giving compost maturity and removal of disease-causing organisms,aerobic compos-ting under 50 ℃ seemed to be the best option.
