“益生菌酵素”处理养猪场污水试验初报

Preliminary report of treating piggery wastewater with “Probiotics ferment”

摘要: 应用“益生菌酵素”处理养猪场排放的污水,化学需氧量下降66.7%,五日生化需氧量下降65.9%,悬浮物下降93.5%,氨氮下降70.4%,总磷下降42.9%;养猪场污水的化学需氧量、五日生化需氧量等指标达到农田灌溉用水水质标准。

Abstract: “Probiotics ferment” was applied to treat piggery wastewater, the results showed that the chemical oxygen demand (COD) decreased by 66.7%, five-day biochemical oxygen demand (BOD) decreased by 65.9%, suspended substances declined by 93.5%, ammonium nitrogen and total phosphorus decreased by 70.4% and 42.9% respectively. After treatment, the indexes of COD and BOD in piggery effluent reached the standard of irrigation water quality.
