摘要
猪场废水厌氧发酵后的沼液具有较高浓度的腐殖酸等难降解有机物,虽然其有机物浓度明显下降,但在后续好氧处理中更难为微生物生长利用。本文采用常规的SBR工艺处理猪场养殖废水厌氧发酵产生的沼液,重点考察SBR工艺处理猪场沼液的可行性,以期为猪场废水资源化与达标处理探索出一条经济高效的厌氧发酵-兼氧/好氧处理工艺。
The biogas slurry from anaerobic treatment of pig farm wastewater still has a high concentration of humie acid and other refractory organics. It is more tough for the aerobic bacteria in the postprocessing though the organic matter concentration decreased significantly. In this paper, the anaerobic fermentation slurry from pig farm wastewater treatment system was treated by SBR process. Ephasis were put on the feasibility of SBR process treating anaerobic fermentation slurry, so as to find an effective and economic way for standard treatment and recycle of pig farm wastewater.
