含油污水池废气生物除臭技术的应用
Date﹕2021-09-14|Source:Eclear Environmental

今天羿清环保将和你谈谈含油污水池废气生物除臭技术的应用,希望对你的日常环保设备系统设计有所帮助。

石油化工厂芳烃装置含油污水池承接多种生产装置排放的含油污水,包括联合装置在运行、驾驶和停车过程中各工艺设备的所有冲洗水或周期工艺排放水,以及停机维修或设备正常切换时偶然被油污染的冲洗水、初期雨水、消防排放水等。整个处理系统包括初级废水池(A-2601)和带波纹板油水分离器的二级废水池。

采用生物滤池废气除臭处理技术,对污水池池盖和废气除臭技术改造,取得了良好的处理效果。

生物除臭设备

废气生物除臭法是利用微生物的新陈代谢活动将恶臭物质分解成无臭或少臭物质的处理方法。自然界中存在分解恶臭或通过诱导产生分解酶的微生物。除臭过程由三个阶段组成:第一阶段,气味与水接触并溶解在水中,这个过程遵循亨利规律;第二阶段,水溶液中的气味成分被微生物吸附吸收,气味成分从水转移到微生物体内;第三阶段,进入微生物细胞的气味成分作为营养物质被微生物分解利用,从而去除污染物。生物除臭法是一种安全可靠的处理方法。通过以上三个步骤,臭气处理效率一般可达95%以上。此外,生物滤池将臭味污染物分解为二氧化碳和水,无二次污染,其生物分解反应式如下

污染+O2微生物细胞+CO2+H2O。

影响生物除臭效果的主要因素。

1进气流量和质量浓度;

2滤床微生物的营养保养;

3湿度、温度和酸碱度;

4填料;

5是设备腐蚀处理。

综合考虑进气流量和质量浓度、营养液浓度、除臭装置湿度、温度和酸碱度、填料等重要参数,生物除臭技术能有效提高系统臭气净化率。
