生物滤池除臭系统在污水除臭中的应用

目前大多数已建成的污水处理厂除臭设施排放标准均为93版国家排放标准的厂界二级,随着城市的不断快速发展,已经不满足新版地方标准或新版国标除臭标准。

越来越多的除臭提标改造工程需要对未加盖臭气源进行加盖密闭,并增设新的除臭设施,采用羿清“生物滤池除臭+活性炭吸附箱除臭”的组合式除臭系统,臭气通过除臭系统处理后降低致臭成分浓度,净化后达标排放。

生物滤池除臭系统在污水除臭中的应用

除臭系统原理

生物滤池除臭为主处理工艺,运行成本低,活性炭吸附箱置于生物除臭后端,经生物除臭处理后的气体若达标,可直接通入风机排放;若排放不达标,可通入活性炭吸附装置,臭气穿过活性炭过滤吸附层时,气体中的致臭分子被活性炭截留吸附,从而达到过滤净化的目的。

生物除臭工艺

生物氧化处理污染物的转化过程是以废气作为微生物的营养源,通过微生物吸收、代谢将其转化为二氧化碳、水和有机酸等代谢产物,污染物中的含硫化合物、含氮化合物将被氧化分解成硫(硝)酸盐和亚硫(硝)酸盐,沉积在系统的滤液中,定期或定量进行排放。这是一个物理、化学、物理化学以及生物化学反应相互协调的过程。

臭气通过耐腐蚀强的玻璃钢管道进行输送。选用的离心风机叶轮和壳体均为耐腐蚀性强的玻璃钢材质,可根据工况不同采用不同的转速,确保风量满足设计处理臭气量的要求,适应于腐蚀性空气条件下的长期24小时连续运行。为保证有效排风和防止泄露,风机为后置式,每套除臭设备配备风机均为11备。

生物除臭系统日常运行操作简单,无需添加任何化学药品,能耗低 总而言之,污水处理厂生反池及预处理区域臭气加盖至关重要,结合现场实际运行需求合理布局,最大程度上降低了臭气处理气量,有效抑制了臭气的外溢。

此外,日常对除臭设备配套的附属设备进行巡视及维护,能更好的发挥除臭设备的性能,确保处理效果达标排放;羿清环保污水除臭设备组合式系统,适合在污水处理厂等恶臭气体成分复杂,浓度高等环境下使用,且操作简单、能耗低,维护工作量小。
