摘要
对饮用水系统中生物膜的形成和影响生物膜形成的各种因素进行了阐述。生物膜控制技术包括降低有机物含量、物理化学方法、酶试剂控制、分散剂使用、紫外消毒等。天然水体中生物膜对剥离剂和紫外具有一定的抗剥离能力,常规手段难以有效去除饮用水系统中的生物膜,即使500mg/L的剥离剂也难以去除已经形成的生物膜。
The formation of biomembrane for drinking water system and the effective factors are summarized in the paper. The biomembrane control technology includes decreasing the content of the organism and physical chemistry method and enzyme reagent control and dispersant usage and ultraviolet disinfection and so on. The biomembrane in natural water is against to the release agent and UV. It is difficult to remove the biomembrane in natural water effectively with normal methods, even there is release agent with concentration of 500mg/1.
