摘 要: | 沼液的深度净化处理是集约化畜禽养殖废水无害化处理的必由之路,本研究旨在筛选处理猪场厌氧消化液的最佳工艺条件组合,为养殖废水资源化循环利用提供科学依据和技术支撑。采用水质相关国家标准方法,选取2个复合菌剂(A、B),3个接种量(0.5、1.0、5.0%),2个通气量(2mg/L、4mg/L),比较研究不同处理条件组合对猪场沼液的净化效果。实验表明:12个组合处理均对猪场沼液具有不同程度的净化效果,能够有效去除猪场沼液生化需氧量(BOD5)、总磷(TP)、粪大肠菌群(FC, Fecal Coliform),各自去除率最高分别达到90.0%、82.0%、99.9%。综合各项评估指标,工艺1、4、6优于其它组合,其中工艺4为最优组合。

Abstract: | The aim was to study the treatment of piggery biogas slurry with different Process Combination (PC).12 process combinations were used to remove BODs, NH3-N, TP, FC (Fecal Coliform) from biogas slurry, and their performances were compared. The results showed that the maximal removal rates of BODs, TP, FC were up to 90.0%, 82.0%, 99.9%. The experiment verified the removal rate of PC1, 4, 6 was more effective than other process combinations. |
