污水站除臭的标准流程是什么?

生物滤池除臭能有效地降低臭气中的有毒物质,那么,该工艺步骤是什么呢?特别是什么?下一步,我要详细介绍一下污水站除臭的标准流程。

污水站除臭

恶臭危害

在石油加工污水处理场地中,斜板隔油池、气浮池、污泥脱水等多为敞口运行,挥发出大量无组织废气,包括大量臭气,如苯系物。它对环境造成污染,对员工及周边居民的身心健康和生活质量构成潜在威胁。

循环水系统

设备滴滤池内的滴滤液由循环泵抽进,经过过滤过滤后,被滴滤单元内的喷淋系统均匀喷入滴滤介质,参与亲水性气体组分的滴滤过程;滴滤液在重力作用下沉降到滴滤池中,滤液中溶解的污染物被大量微生物捕捉并降解,从而使滴滤液能够循环使用;当滴滤液 pH值超过设定值时,启动排污泵外排一定量的滴滤液,自控系统根据预设液位值自动打开电动阀,确保滴滤液的 pH和液位处于正常范围。循环水来源于公用工程现场的供水管网。

设备的氧化单元加湿用水来自现场公用工程给水管网,加湿后通过缓冲罐在自控系统预设的时序逻辑控制下,定时开启电动阀对该单元内的生物氧化介质进行湿化,以保障介质微生物正常生命活动对环境湿度的要求。部分生物体遗骸加湿后,受重力作用,沉降至基底,经池底导流管道回流至滴滤装置底部滴滤器。

为实现无二次污染和无二次污染的上海羿清环保生物滤池除臭装置,得到业界的广泛赞誉。
