工业循环水系统在水质处理过程中有机物与无机物的浓度逐渐升高,绝大部分有机物是可生物降解的,是微生物的营养源。适宜的生存环境和充足的营养物使得微生物在循环水系统大量繁殖,形成生物粘泥。生物粘泥会给系统运行造成许多障碍。传统上用于工业循环水系统中的杀菌剂,其作用机理是通过直接破坏微生物生命过程和细胞核物质来控制微生物的繁殖。这些杀菌剂在杀死细菌的同时对人体及环境也容易造成极大的危害。而Tallofin(太乐芬 )通过与微生物之间的分散、包覆、剥离多重物理作用达到控制细菌的目的,并且对人体及环境不会造成危害。因此,我们在第三循环水场进行了现场应用试验,通过对水质指标的跟踪分析,确定该药剂的使用效果及最佳投加方法。

In the process of t reat ing indust rial circulating water, the concent rat ion of organic and inorg anic compoundsare get ting hig her g radually.The majority of organisms in the indust rial ci rculating water sy stem, w hichare the nut rit ive sources of the microorg anism, are biodegradable.Suitable circumstances and suf ficient nutrimentsmake i t possible for the microorganism to reproduce heavily and form biolog ical sludge.The biologicalsludge can bring lots of obst ructions in the operatio n of the w hole system.Bactericide tradit ionally takes effectthroug h destroying the living process of the microorganism directly, as w ell as the uncleus, so as to control thereproduction.While the bactericide is dest roying the bacteria, it is harmful to our human bodies and causes environmentalpollutio n.But Tallofin finishes bacteria control by physical methods, and is harmless to human bodiesand the environment.Therefore, an experiment at the Thi rd Ci rculating Water Unit has been made to evaluatei ts efficiency and determine the optimum adding methods by t racking analy sis of water quality.
