摘要:
本文根据脱氮硫杆菌在厌氧条件下的生理特性，以生物滴滤塔为反应器、脱氮硫杆菌为功能菌种进行了同时脱硫脱硝的实验研究。利用w垃圾渗滤液进行填料挂膜并驯化后得到了脱氮硫杆菌菌群，考察了进气浓度、液体喷淋量、入口气体流量等因素对H2S和NO脱除效率的影响，确定了较佳的实验条件。
According to the biological characteristics and suitable growth conditions of thiobacillusdenitrificans, experimental study of simultaneous desulfurization and denitrification by Thiobacillus denitrificans under anaerobic conditions was carried out in biotrickling filter filled with packing. The effect of gas flow, concentration of inlet gas, spray volume of circulation liquid, etc., on H2S and NO removal efficiency were investigated, and the optimum experimental conditions was determined.
