随着城市垃圾的堆积,恶臭严重影响人们的日常生活。因此,市政污水除臭受到人们的广泛关注。那么市政污水除臭的臭气有哪些特征呢?接下来我将具体介绍一下。

市政污水除臭

恶臭气体的散发特征

1污水泵站不同位置的恶臭散发情况有所不同。

2总体而言,污水泵站在夏季的恶臭散发量要大于秋季,恶臭散发量与来水水质和运行水位有关,在水位低且输送管道非满流情况下易产生高浓度的恶臭。格栅井的水力搅动(水泵及格栅机运行时)也易造成恶臭散发的增加。

3污水泵站恶臭气体的散发点较多,除敞口格栅井外,还包括潜水泵顶空的盖板缝隙、进水井盖板缝隙、出水口的散气井口、出水口的阀门井开口以及未密闭收纳的栅渣等。

工艺流程

臭气经收集后通过风机输送到生物滴滤床内进行净化,再经过活性炭吸附柱进一步净化后达标排放,生物滴滤床和活性炭吸附柱的喷淋水排入泵站下水道。采用活性炭吸附柱作为后处理单元主要是为了在生物滴滤床运行出现故障时保证处理效果。生物除臭反应器类型主要有传统的生物过滤床、生物洗涤器等,新一代得到广泛研究和应用的生物反应器有生物滴滤床等。

市政污水除臭

上海羿清环保生产的生物滤池市政污水除臭设备能够有效减少城市污水臭气,而且其具有高效、节能、无二次污染等优点,受到一致好评。
