生物除臭技术的应用及效果评价

生物过滤器常置于石化废水处理工艺的末端环节。在完成处理臭气之后,分解产物随着排水管道去到污水系统,处理后的尾气通过排气口排到大气中。排气管上都会设置臭气物质测量仪或者是表盘,以此来监督除臭的效果。在本次研究当中,对生物除臭技术的应用内容进行分析,案例公司在开展废水恶臭气体处理时,在生物滴滤塔当中填满装有生物滴滤的填料,这一填料采用西原公司碳质填料。

生物除臭技术的应用及效果评价

臭气当中部分的疏水物质与大部分的亲水物质都会被吸附到填料上的生物膜中。在恶臭气体进入之后,能被生物群所捕获并且进行降解,由于生物氧化池当中填装生物填料采用比表面积较大的碳质填料。来自于污水处理厂中VOCS气体,会被填料储存,然后被附着的微生物菌群捕获,进而被分解。这个过程的发生十分迅速,从而可源源不断的处理收集来的臭气物质。在末端降解之后,恶臭物质会转化为二氧化碳和水,以及一些少量的盐类物质。

该化工废水处理厂在运行期间,生物除臭系统同步启动,臭气通过加湿段和生物过滤器实现除臭之后,尾气随着排气筒排出,在各个装置功能达标的状况之下,生物过滤器的除臭效果表现良好,而排出的气体浓度能达到我国《大气污染物综合排放的标准》。通过检测,经生物过滤器除臭之后,出口臭气浓度大为减低,并能达到可排标准。

用过生物除臭处理,对化工废水中的臭气、硫化氢以及氨气、VOCS等都有很好的控制效果。生物除臭技术是采用生物氧化降解的作用来分解臭气物质,其核心在于微生物处理能力,一方面取决于除臭微生物富集的量,另一方面是除臭微生物的活性。在对化工废水厂进行除臭时,常选用比表面积大,易于生物富集的碳质填料,另一方面采用厂区中水作为填料加湿介质,可促进特异微生物的变异,从而更好的去除厂区产生的恶臭。相较于其他除臭技术而言,生物除臭因其较高的处理效果及较低的运营成本会更加适合常规的化工污水处理。

生物除臭技术的应用及效果评价

上海羿清环保生产的生物滤池臭气处理设备能够有效处理臭气,而且不会产生二次污染,受到业内人士的一致好评。
