摘    要:为了研究原水水质对输水管道生物膜中异养菌(heterotrophic,HPC)生长情况的影响,采用配制水样来模拟Ⅱ、Ⅲ和劣Ⅴ类地表水,利用管道模拟反应器对其进行分析.结果表明:反应器运行45 d后,分别采用Ⅱ、Ⅲ和劣Ⅴ类地表水作为进水的各模拟反应器生物膜中HPC数量均高于出水HPC数量,且其生物膜中HPC数量分别稳定在1.1×105、2.8×105和5.9×105CFU/cm2;原水UV254、正磷酸盐(PO3-4)质量浓度和浊度均与生物膜中HPC数量呈正相关关系,其相关性系数r分别为0.506、0.552和0.272.

关 键 词:原水水质  输水管道  生物膜  异养菌(HPC)

Abstract:The growth of heterotrophic( HPC) in water distribution pipes was studied,simulation pipeline reactors were used to simulate the water situation. Water samples were prepared in a laboratory to simulate Class Ⅱ,Ⅲ andⅤ or worse of the surface water standard. Results show that the quantities of HPC in the biofilm are significantly higher than those in the bulk water,and are stabled at 1. 1 × 105,2. 8 × 105,and 5. 9 ×105CFU /cm2,respectively,after 45 days. UV254 concentration and orthophosphate( PO3-4) concentration and turbidity in raw water are all positively correlated with the quantity of HPC in the biofilm,and the correlated coefficient are r = 0. 506,0. 552,and 0. 272,respectively.
Keywords:raw water quality  water distribution pipes  biofilm  heterotrophic (HPC)
