生物法臭气处理技术
生物法在国内最常用的是生物滤池法,主要包括加湿塔和生物滤床。系统运行过程中,对湿度、温度、pH、填料孑L隙率、停留时间等指标的控制是关键。生物滤池建成后,需要维持适宜的温度和湿度,控制因代谢中间体或产物造成的pH下降等,如果能够按照设计工况连续正常运转,其运行成本低的优势还是比较明显的。

生物法在国内比较常用的是生物滤池法,主要包括加湿塔和生物滤床。系统运行过程中,对湿度、温度、pH、填料孑L隙率、停留时间等指标的控制是关键。生物滤池建成后,需要维持适宜的温度和湿度,控制因代谢中间体或产物造成的pH下降,如果能够按照设计工况连续正常运转,其运行成本低的优势还是比较明显的。

生物法臭气处理技术

近几年生物法除臭技术不断创新,出现了生物滴滤和生物洗涤等新工艺,其中生物滴滤技术不仅适合处理气液分配系数<10的恶臭污染物,也适合<01的恶臭污染物,而且具有占地小、投资少等优势,因此得到广泛推广。

离子法主要用于低浓度的臭气处理,离子法对于乙酸、醛等有机臭气成分的去除率高达90%,但对于H2S的去除率不超过45%。而餐厨垃圾堆肥处理过程中主要的臭气成分即为H2S,且浓度也较高,因此,该技术只适合作餐厨垃圾除臭的辅助工艺。另外,离子发生器的关键元件离子管会随着时间的推移逐渐衰退,相应的除臭效率也会逐步下降,使用12a后,离子管产生的离子强度不超过高值的12,而且由于餐厨垃圾堆肥产生的臭气湿度较高,其处理效率也会受到较大的影响。

上海羿清环保公司则主要采用生物除臭技术,该公司主要从事于生物除臭方案设计和设备生产的环保公司,其生产的生物滤池臭气处理设备能够有效处理恶臭气体,而且不会产生二次污染,受到业内人士的一致好评。
