  • 摘要: 研究以集中型沼液为对象,考察了微电解-电极-SBBR组合工艺的处理效果。研究结果表明,在常温条件下,铁炭微电解反应按照推荐的反应参数的条件(曝气量为15.0 L/(min·L)、初始pH值为4、Fe/C为2:1、HRT为2.5 h、反应级数为3级),电极-SBBR采用瞬时进水、厌氧1.0 h、曝气4.0 h(通电)、缺氧/厌氧2.0 h(通电)、出水、闲置的运行工序。在反应器稳定运行的条件下,对化学需氧量(COD)、氨氮(NH4+-N)、总磷(TP)、固体悬浮物(SS)的平均去除率分别为92.2%、93.5%、93.2%和98.4%。出水的COD、NH4+-N、TP和SS的浓度能够达到《畜禽养殖行业污染物排放标准》(GB 18596-2001)的要求。
    Abstract: Micro-electrolysis and electrode-sequencing batch biofilm reactor were used to treat biogas slurry, the treatment efficiency of the reactor was investigated. The result showed that under the normal temperature, the reaction conditions of micro-electrolysis experiments with iron-carbon were as follows: aeration rate of 15 L/(min·L), initial pH value of 4, iron-carbon volume ration of 2:1, HRT of 2.5 h, 3 order reactions. The operating conditions of micro-electrolysis and electrode-SBBR were instantaneous inflow, anaerobic processing 1.0 h,aeration 4.0 h(electricity), anoxic or anaerobic processing 2.0 h(electricity), outflow, idle.Under the stable operation conditions of the reactor, the average removal rates of COD,NH4+-N,TP and SS reached 92.2%,93.5%, 93.2% and 98.4%, respectively.COD,NH4+-N,TP and SS in the effluent meet the requirements of pollutant discharge standard in Discharge Standard of Pollutants for Livestock and Poultry Breeding (GB 18596-2001).
