- Abstract:
- The improved SBR method was used to treat the manure wastewater of dairy farms, and the effects of aeration time, sedimentation time, sludge concentration and other factors on the wastewater treatment effect of dairy farms were investigated. The results showed that when the aerobic SBR reactor treated dairy farm wastewater with aeration for 6 h, precipitation for 60 min, and the influent CODCr changed between 500~2 500 mg/L, the SBR system operated stably, and the removal rates of CODCr, TKN and NH4+-N were above 80%, 70% and 85%, respectively. The addition of hypoxic section of SBR reactor improved the removal effect of TKN and NH4+-N.
