微生物菌剂处理猪场沼液效果研究

Study on Treatment of Piggery Biogas Slurry with Microorganism Preparation

利用人工模拟活性污泥的方法,比较研究不同微生物菌剂对猪场沼液的净化效果,旨在研制适合处理猪场沼液的复合菌剂,为养殖废水无害化处理和资源化利用提供科学依据。试验结果表明:3种微生物菌剂对猪场沼液均具有一定的净化效果,能够较好地去除沼液生物需氧量、总磷、粪大肠菌群,最高去除率分别达到61.5%、83.0%、99.0%,发芽试验也证实植物毒性的良好去除效果,最高发芽率提高38.3个百分点,发芽指数提高45.2个百分点;对化学需氧量、氨氮、全盐量等指标均具有一定的去除效果,最高去除率发分别达到54.9%、48.4%、31.8%。综合评估,光合菌剂(PMP)处理效果优于复合菌剂(CMP)和发酵菌剂(FMP)。

The research aimed to study the treatment of piggery biogas slurry with Microorganism Preparation. Compound Microorganism Preparation （CMP）, Fermentation Microorganism Preparation （FMP） and Photosynthetic Microorganism Preparation （PMP） were used to remove BOD 5 , COD cr , NH 3 -N, TP, Fecal Coliform, and Total Salt from biogas slurry, and the effects were compared. The results showed that the maximal removal rates of BOD 5 , TP, FC were up to 61.5%, 83.0%, 99.0%, and those of COD Cr , NH 3 -N, TS were up to 54.9%, 48.4% and 31.8%. In conclusion, the removal rate of PMP was more effectively than CMP and FMP.
