生物滤池除臭已经广泛运用于各大城市,生物滤池除臭效果明显,而且不会产生二次污染。那么,影响生物滤池运作的因素有哪些呢?

滤层比表面积与孔隙率

生物学膜法的主体是生物膜,过滤面积越大,生物膜的表面积越大,生物膜的数量越多,净化功能越强;孔隙率越大,滤床越厚,过滤作用越强,孔隙率越大,过滤作用越大,越有利于净化功能。

滤布层高度

过滤层高度不同,生物膜量、微生物种类、对有机物的脱除速度不同;滤床上层,废水中有机物浓度高,营养物质丰富,微生物繁殖快,生物膜量多,主要以细菌为主,有机污染物的去除速度较高;随着滤床深度的增加,废水中的有机物浓度较高,微生物数量较多,主要是细菌数量较多,有机污染物去除率较高;随着滤床深度的增加,废水中的有机物含量较高,有机物的去除率较高;随着滤床深度的增加,废水中的有机物浓度较高,有机物含量较高;随着滤床深度的增加,废水中的有机质含量较高,生物膜含量较高,微生物含量较高,生物膜含量较高,生物膜含量较高,生物膜含量较高,生物膜含量较高,生物膜含量较高,生物膜含量较高.

生物滤池

液压负载

水载----m3/m2. d,或 m/d;----滤速;②水力容积负荷----m3/m3. d在有机负荷较大时,生物膜的生长速度也会加快,可能造成滤料堵塞,这时就要调整水力负荷,当水力负荷增加时,可提高水力冲刷力,维持生物膜厚度,一般通过出水回流来解决。

负荷较大的生物滤池通常采用塔式生物滤池回流。优势:①滤池可获得连续投加的废水,不考虑原废水的流量有多大的波动性,使其工作更稳定;②可冲刷清除老化生物膜,降低膜厚,抑制滤池内蝇的滋生;③平衡滤池负荷,提高滤池的效率;③可以稀释和降低有毒有害物质的浓度及进水有机物浓度。

氧气供应

一般情况下,生物滤池通过自然通风来保证供氧;影响生物滤池自然通风的主要因素有:①池内温度与气温的差异;②滤料孔隙率及风向等;③滤料孔隙率和风力等;

上海羿清环保是一家专注于生物滤池的环保公司,其生产的生物滤池除臭设备能够有效处理恶臭气体,而且不会产生二次污染,受到业内人士一致好评。
