摘  要:
该试验对SBBR与电极-SBBR工艺处理沼液中COD、氮、磷进行对比研究试验。结果表明,在相同工况条件下,电极-SBBR工艺对沼液中COD、NH_4~+-N及TP的去除率比SBBR工艺分别提高了4%~7%,1%~2%和4%~9%,电极-SBBR工艺对污染物的去除能力更强;推荐电极-SBBR处理沼液的最佳运行工况:运行周期为7.0 h,进水→厌氧(1.0 h)→曝气(4.0 h、通电)→缺氧/厌氧(2.0 h、通电)→出水→闲置,对沼液中COD、NH_4~+-N和TP的去除率分别为80.39%、92.52%和59.36%。

摘  要:
The comparative experiment was carried out on SBBR and electrode-SBBR process for treatment of biogas slurry of COD,nitrogen,and phosphorus. The test results show that under the same condition,the electrode-SBBR process of biogas slurry of COD,NH_4~+-N and TP removal rate than that of SBBR process were increased by 4%-7%,1%-2% and 4%-9%,stronger ability for the removal of pollutants electrode-SBBR process; The recommended running period of electrode-SBBR process for treatment of biogas slurry as: operating cycle was7. 0 h,adding water→anaerobic processing( 1. 0 h) →aeration( 4. 0 h,electricity) →anoxic or anaerobic processing( 2. 0 h,electricity) →effluent dewatering→idle,the removal of COD,NH_4~+-N and TP in the biogas slurry rate were 80. 39%,92. 52% and 59. 36%.
