污水废气处理技术
城市污水处理厂易散发臭气的构筑物主要包括进水闸井、粗格栅间、进水泵房、细格栅间、沉砂池、生化池、污泥池和污泥脱水机房等。在较早建造的污水处理厂,由于受当时的设计和建设标准的局限,污水厂内的污水处理和污泥处理设施大多采用敞开式,构筑物内污水或污泥在输送和搅动过程中会产生大量的恶臭气体,从而污染周边环境。

城市污水处理厂易散发臭气的构筑物主要包括进水闸井、粗格栅间、进水泵房、细格栅间、沉砂池、生化池、污泥池和污泥脱水机房等。在较早建造的污水处理厂,由于受当时的设计和建设标准的局限,污水厂内的污水处理和污泥处理设施大多采用敞开式,构筑物内污水或污泥在输送和搅动过程中会产生大量的恶臭气体,从而污染周边环境。

恶臭污染控制技术

恶臭的治理技术包括恶臭源抑制技术、恶臭源散发控制技术和恶臭气体处理技术。

恶臭源抑制技术

大多数的恶臭源抑制技术亦即液相恶臭控制技术,都是基于降低恶臭气体的排放量与排放浓度的考虑,包括控制恶臭气体的释放和污水及其中化合物所处状态(如流态、含氧条件、腐蚀物含量等),恶臭源抑制技术主要包括:

(1)良好的运行维护(尽可能减少厌氧细菌的繁殖),主要内容包括保持系统内水流通畅;避免大量的油脂和污物在死角处积累;严格按照设计和操作规范要求控制进水水质等。

(2)上游预处理,避免系统内厌氧条件的出现,主要内容包括注入空气和纯氧;加氯、金属盐和硝酸盐等。

(3)直接投加或在旁路管中投加化学药剂抑制厌氧细菌生长,主要内容包括加过氧化氢、高锰酸钾等氧化剂;

氧化法

氧化法即利用恶臭气体大多为还原性物质、氧化剂具有较强氧化性的化学特性,使臭气中的污染因子有效氧化分解,以降低恶臭浓度。目前常用的氧化剂包括臭氧和活性氧。

臭氧氧化法即利用臭氧的强氧化性,使臭气中的化学成份氧化,达到脱臭目的。臭氧是相对不稳定的气体,很容易分解成氧气,在湿度大的场合尤甚,因此臭氧往往是现场制备的。活性氧氧化技术是指直接利用活性氧发生装置产生具有极强氧化能力的活性氧对臭气中的化学成份进行氧化来净化气体。

污水废气处理技术

上海羿清环保专注于生物除臭,其生产的生物滤池污水废气处理设备能够有效处理臭气,而且没有二次污染,受到业内人士一致好评。
