家蝇幼虫生态处理禽畜粪尿的环境保护效果研究

To explore the environment protective effect of ecological treatment of manures by housefly larvae. The pig manures were ecologically treated by housefly larvae and the simple fermented non-treated pig manures as control .The following results were observed after ecological treatment:.1.The contents of 3-MI, BOD and COD in the treated pig manures were significantly lower than that of control.2. The number of colibacilliary colony significantly decreased in the manures treated with housefly larvae, and the extract of housefly larvae (both homogenate and supernatant) showed the remarkable anticolibacillary action in vitro.3. The breeding capability of housefly and mosquitoes reduced in the pig manures treated by housefly larvae.4. The content of total nitrogen, quick-acting phosphorous, total potassium, and the trace-elements iron and manganese significantly increased, but that of organic substance and total nitrogen decreased..These combined results showed that it is possible to reduce the environment pollution of manures by treatment with housefly larvae.

以自然熟化合微生物发酵处理畜禽粪尿为对照：研究家蝇幼虫生态处理禽畜粪尿后粪肥肥效的变化及其对禽畜粪尿中氮、磷、钾等营养素的回收和粪臭的清除能力；观察经家蝇幼虫处理后禽畜粪尿对蚊蝇的孳生能力和份肥中病原微生物的致病能力。为进一步利用家蝇治理禽畜粪尿对环境的污染提供实验和理论依据。..
