理想的生物除臭填料应该具备哪些特征?
理想的生物除臭填料应该具备以下特征: 1)最佳的微生物生长环境——营养物、湿度、pH和碳源的供应不受限制; 2)较大的比表面积——接触面积、吸附容量、单位体积的反应点多; 3)一定的结构强度——防止填料压实,后者会使压降升高、气体停留时间缩短; 4)高水分持留能力——水分是维持微生物活性的关键因素;

理想的生物除臭填料应该具备哪些特征?

理想的生物除臭填料应该具备以下特征:

生物除臭

1)适宜的微生物生长环境——营养物、湿度、pH和碳源的供应不受限制;

2)较大的比表面积——接触面积、吸附容量、单位体积的反应点多;

3)一定的结构强度——防止填料压实,后者会使压降升高、气体停留时间缩短;

4)高水分持留能力——水分是维持微生物活性的关键因素;

5)高孔隙率——使气体有较长的停留时间;

6)较低的体密度——减小填料压实的可能性。显然,在上述六个特征中,1)和4)二个关系除臭微生物生存条件的特征在生物滴滤塔中根本不具备。

鉴于此,要维持生物滴滤塔的除臭效果,必须配备一套完善的喷淋、监测、调节及控制的组合系统。

首先是温度,微生物的生长有适宜的温度范围,一般将温度控制在25~35℃。

其次是pH值,能分解H2S的细菌有嗜中性pH环境(pH6.5~7.5)和嗜酸性pH环境(pH2.0~3.0)两种。但是,臭气成分中还含有NH3,其硝化反应需要碱性环境。因此,需要向循环液中投加适量的可溶性碱,调节循环液的pH,以调节塔内的pH,从而保证较好的脱臭效果。

再次是需要额外配备喷淋泵,维持适宜的循环喷淋量,以便有效地防止填料干燥,并精确地控制营养物浓度与pH值。一般认为,随着喷淋量的增加,臭气的净化效率增加,但是过大喷淋水的冲击,又易导致生物膜脱落。一旦发生生物膜脱落,修复工作需专业人士进行,周期大约需要16个月。

上海羿清环保就是一家专注于生物除臭的环保公司,其生产的生物除臭设备能够有效处理恶臭废气,受到业内人士的一致赞誉。
