中小型养殖场沼气工程技术的应用

The Application of Biogas Engineering Technology at Middle and Small-Sized Breeding Farm

中小型养殖场采用厌氧污泥床处理有机污水取得了较好的效果。工程实践证明,该工艺不仅投资省,运行费用低,而且产生可供利用的沼气,利用沼气发酵的残余物沼渣和沼液可培植无公害农产品。该技术具有很好的推广价值。

Treating organic sewage sludge of small and medium-sized farms by anaerobic sludge bed has achieved good results. Engineering practice has proved that the process not only involves less investment and running expense, and can produce biogas thatcan be utilized. Besides, the remnants and slurry of biogas can be used to plant pollution-free agricultural products. The technology has very good promotional value.
