庆阳市采用塑料大棚发酵畜禽粪污模式初探

为了提高粪污发酵速度、缩短发酵时间,减少环境对粪污的承载和消纳能力,笔者通过采用塑料大棚模式发酵粪污,以提高粪污内部温度,添加一定的微生物菌剂,采用高温好氧堆积发酵,在西北气候条件下,使小型养殖场(合作社)粪污发酵比常温堆积发酵时间缩短了40～100 d,使粪污尽快得到还田利用,减少了环境对粪污的承载力。

Preliminary Study on the Model of Fermentation of Livestock and Poultry Manure by Plastic Shed in Qingyang City

In order to increase the speed of manure fermentation, shorten the fermentation time, reduce the carrying and absorption capacity of the environment for manure. We fermented manure by using the plastic canopy model, to raise the temperature inside the manure. Adding a certain microorganism, fermentation by high temperature, aerobic accumulation, in the Northwest climate, reduced the time for manure fermentation in small farms by 40 to 100 days compared to normal temperature storage. The manure pollution can be used as soon as possible and the bearing capacity of the environment to the manure pollution can be reduced.
