生物滤池如何处理制药污水厂的废气

伴随着我国经济的持续快速发展,能源消耗不断增加,表现出区域性和复合性,在大气严重污染事件中存在着隐忧,大气环境形势十分严峻,制药、化工等重点污染行业废气污染尤为突出。那么,如何采用生物滤池处理制药污水厂的废气呢?

 生物除臭设备

制药厂生产过程中一些没有回收价值的副产品.有机溶剂常被排放到废水处理系统,在污水处理过程中,会产生大量的VOCs,如甲苯、乙酸丁酯、二氯甲烷等;废水中含有有机物质如硫磺等,细菌作用下,会产生硫醇、硫醚等有毒有害和臭味物质,这类排放物排放严重污染环境,对人类健康和生态安全构成威胁.

 

在生物滤池中通过风机先进入水吸收塔,再用新鲜水进行吸收预处理,溶解部分水溶性好的污染物,调整浓度和温度,湿度等。接着进入生物过滤器,通过附着在生物填料上的混合微生物代谢,把排放物中的污染物当作碳源、用能,同时将CO2H2O等简单无机物降解,在生物滤池的调试过程中和废气高浓度事故排放时,打开化学氧化装置,减少污染物超标排放的危险。在系统运转过程中,有少量废液被排入污水站好氧单元处理。

  

生物滤池在低酸碱度的环境下工作,具有处理效率高、能耗低、投资、运行成本低、无二次污染等优点,可广泛用于制药、化工等行业的低浓度含硫废气的治理场合。近几年来,国内高校和科研机构在这一领域进行了大量研究,近几年尾气生物净化技术在市政领域污水提升泵站中得到广泛的应用。

 

羿清环保生物滤池除臭技术治理污水厂恶臭气体,利用生物滴滤法对污水站臭气处理等进行了研究,取得了较好的效果。
