摘要
利用固定生物膜滤池控制硫化氢气体是一种经济有效的方法。试验条件是：温度２０℃～３３℃、滤层喷淋水量６００ｌ／ｍ３·ｄ。当进气Ｈ２Ｓ浓度Ｃｉｎ≤２３０ｍｇ／ｍ３，生物滤池Ｈ２Ｓ负荷Ｌ≤５６０ｇＨ２Ｓ／ｍ３·ｄ时，Ｈ２Ｓ去除率达到１００％，当Ｃｉｎ≤５７０ｍｇ／ｍ３，Ｌ≤２４３０ｇＨ２Ｓ／ｍ３·ｄ时，Ｈ２Ｓ去除率高于９８％，出气中Ｈ２Ｓ浓度≤１０ｍｇ／ｍ３。
The control of hydrogen sulfide using biological fixed-film filter is an economical and effective method. The experimental conditions were temperature of 20～30℃ and water spray quantity of 600l/m￣3(packing)·d. 100% of H2S removal efficiency was obtained at the loading rate≤560gH2S/m3·d with Cin≤230mg/m3 (infuent H2S concentration). However, up to 98% of H2S removal efficiency was obtained at the loading rate≤2430gH2S/m3·d with Cin≤570mg/m3 and Cout≤10mg/m3.
