The electrochemical oxidation of the digested effluent from anaerobic digestion of dairy manure was investigated in this study. The digested effluent sample containing with suspended solids was pretreated by filtration for the electrochemical experiment. The influence of direct anodic oxidation and indirect oxidation was evaluated through the use of dimensionally stable anode (DSA) and Ti/PbO2 as anode. The decreasing rate of chemical oxygen demand (COD) was higher at lead dioxide coated titanium (Ti/PbO2) electrode than at DSA, however the DSA was preferred anode for the decrease of ammonium nitrogen (NH4-N) due to the control of ammonium nitrate (NO3-N) accumulation. The results showed that the filtration of suspended solids as a pretreatment and addition of NaCl could improve the whole removing efficiency of NH4-N in the digested effluent on electrochemical oxidation.

对牛粪厌氧消化后的出水进行了电化学氧化研究。对含有悬浮物的消化出水样品进行了过滤处理，以进行电化学实验。采用尺寸稳定的阳极(DSA)和Ti/PbO2作为阳极，考察了直接阳极氧化和间接阳极氧化的影响。二氧化铅涂层钛(Ti/PbO2)电极的化学需氧量(COD)下降率高于DSA电极，但由于控制了NH3-N的积累，DSA电极是降低氨氮(NH4-N)的首选阳极。结果表明，悬浮物过滤作为前处理和投加氯化钠可以提高电化学氧化消化出水中NH4-N的整体去除效率。
