活性炭纤维生物挂膜脱除硫化氢

Removal of hydrogen sulfide gas by biological activated carbon fiber and bio-membrane

生物脱硫法作为一种高效、高实用性的除硫新技术而受到越来越多的关注。以活性炭纤维为微生物载体,通过活性污泥上清液挂膜驯化,考察硫化氢进气量、喷淋量、pH值和硫酸根离子浓度等条件对脱硫效率的影响。研究结果表明,在室温下,硫化氢负荷为90 g/(m3.h),进气浓度控制在3 g/m3,进气量为60 L/h,喷淋量为250～650 L/(m3.d),pH为2～5的条件下,生物活性炭纤维对硫化氢的去除率可保持在98%以上。

As one of efficient and practical desulfurization technologies,biological method is being paid more and more attention.This research is about the effects of the gas-in amount of hydrogen sulfide,sprinkling amount,pH,the sulfate concentration on the efficiency of desulfurization,using activated carbon fiber as a microbial carrier.The test results showed that more than 98% of hydrogen sulfide removal efficiency can be obtained under the following experimental conditions： the cubage load of 90 g/（m3·h）,the concentration of H2S of 3 g/m3,a amount of gas-in of 60 L/h,,a water spray of 250-650 L/（m3·d）,and pH of 2-5
