摘要
为了探讨生物法处理含Ｈ２Ｓ恶臭气体的效率及酸积累问题，利用两种生物反应器进行了处理Ｈ２Ｓ的试验研究．结果表明，生物滤池脱臭效率高，但液相Ｈ２ＳＯ４积累明显，ｐＨ值低．复合式生物膜反应器装有固定一悬浮填料，集生物过滤和生物吸收为一体，当容积负荷Ｎｖ≤１９０ｇＨ２Ｓ／ｍ３·ｄ时，具有很高的去除能力，液相ｐＨ≥６．
To investigate the removal
efficiencies for the malodorous gases containing H 2S and accumulation of H 2SO 4 in the
biological treatment processes,two kinds of reactors were utilized in laboratory studies. The
results showed that the trickling filter had very high deodorization efficiencies and an obvious
problem of H 2SO 4 accumalation. The complex bio film reactor packed with fixed suspended
medium combining biofiltration and bio adsorption has high effeciencies at loading rates NV≤
190 g H 2S/m 3·d and pH of liquid phase≥6.
