摘　　要：以重庆某水厂高有机物、氨氮复合污染水源水为对象,研究了生物炭泥/絮凝-沉淀-超滤组合工艺的活性炭补充对生物富集及效果影响,考察组合工艺效果及与传统工艺对比。结果表明,随着补充炭量的增加,炭泥中的生物量逐渐增加,生物培养罐培养10 d左右完成生物富集,生物量达到90 nmol P/g左右。生物炭泥-超滤组合工艺对COD_(Mn)和氨氮的平均去除率分别为56%和60%,比常规工艺去除率分别提高了26.9%和38%。组合工艺最终出水水质指标达到GB 5749—2006《生活饮用水卫生标准》。Taking the source water with high organic matter and ammonia nitrogen pollution in a waterworks in Chongqing as the research object,the effect of activated carbon supplement of biochar sludge/flocculation sedimentation ultrafiltration combined process on biological enrichment and effect was studied,and the effect of combined process and comparison with traditional process were investigated.The results showed that,with the increase of carbon supplement,the biomass in the carbon sludge increased gradually,and the bio enrichment was completed after 10 d in the bio culture tank,and the biomass reached about 90 nmol P/g.The average removal rate of COD_(Mn) and ammonia nitrogen by the combined process were 56%and 60%,respectively,which were 26.9%and 38%higher than those by the conventional process.The final effluent quality index of the combined process reaches GB 5749—2006“Hygienic standard for drinking water”.
