摘要
采用UASB-A/O/A/O耦合工艺对猪场废水进行处理,研究其对规模化猪场废水的处理效果。结果表明,猪场废水经过该工艺处理后并经过氧化塘处理后,对COD和NH3-N分别达到97.6%,94.3%。工艺出水水质COD≤135 mg·L-1,NH3-N<32 mg·L-1,SS≤50 mg·L-1,出水水质达到国家农田灌溉水质标准(GB5084-2005)。说明该工艺运行稳定,成本较低,适合规模化猪场养殖废水的处理。
Treating of waste water from large scale pig farm by UASB（ Up-flow anaerobic sludge bed）-A / O / A / O coupled process was studied in a real engineering. The results showed that this process could remove 97. 6% of COD and 94. 3% of ammonia nitrogen. The COD in the effluent was ≤135 mg·L^-1,and NH3-N 32 mg·L^-1,SS≤50mg·L^-1. All these data achieved the standards for irrigation water quality（ GB5084-2005）. And the process was stable,the operating cost was low,and so it was feasible for large scale pig farm.
