摘  要：
在北京三家店水库建立150L的反应器,研究了以活性炭为微生物载体的膨胀床工艺对微污染水源水中有机物和氨氮的处理效果及其受温度影响的程度。结果表明,本工艺对有机物和氨氮具有较好的处理效果,对温度具有较强的适应性,常温下(15℃左右)和低温下(<4℃)对CODMn的去除率分别为20%和10%,对氨氮的去除效率大于85%。处理三家店水库出水可以满足二类地表水对CODMn的要求。长期运行水力负荷的冲击并不会对本工艺造成明显的影响,在氨氮不足条件下,通过适当提高水力负荷可增加通过反应器氨氮的量,从而促进其对有机物的去除。

摘  要：
Active carbon can not only absorb organics but also provide space for microorganism to attach in, thus can supply enough time for microorganism to remove sustainable organics. A reactor with volume of 150 liters was build at Sanjiadian reservoir(Downstream of Guanting, Beijing)to study the removal effects of organics and ammonia in light-polluted water by biological active carbon expended bed (BAC-EB). When the water temperature was 1.5 ℃~21 ℃, the concentrations of influent CODMn and ammonia were 4.46~6.58 mg·L-1 and 0.14~0.39 mg·L-1 respectively. The reactor had a satisfactory startup with CODMn removal rate about 70% due to the absorption of active carbon. The removal of organics and ammonia were quite approving under normal temperature (about 15℃) and low temperature (about 4℃), with the CODMn removal rates of 20% and 10% respectively. UV410 and UV254 were also removed quite noticeably, the removal rates both being 20%~30%. Effluent CODMn and ammonia concentration met the GB standard for Class II and Class I for surface water respectively. During long period running, the reactor wasn't affected by the hydraulic compact, but it could not remove insoluble organics. Under low ammonia supplying, higher hydraulic load increased the CODMn removal rate and decreased the startup or re-startup period.
