오존-차아염소산나트륨과 充塡塔에 의한 냄새成分의 除去 = A Study on Oxidation of odorous components by O_3-NaClO and packer tower

국문 초록 (Abstract)

오존-차아염소산나트륨 酸化方式으로 異尿處理場 냄새의 大部分을 차지하고 있는 암모니아와 황화수소를 5/8inch Pall Rinf으로 充塡한 吸收塔을 이용하여 除去하는 實驗을 한 結果는 다음과 같다.
1. 本 實驗에 使用하기 위해 제작된 充塡搭의 壓力損實을 測定해 본 結果 最大 表面積負荷에서 43mmAq/m로 充塡搭의 壓力損失 허용범위 50mmAq/m이내인 것을 확인할 수 있었다.
2. 차아염소산나트륨의 유효염소농도 100ppm 이상에 오존을 17ppm(5l/min)로 注入시킬 때는 H_S 98%, NH_396%의 除去效率을 보인반면, 오존을 添加하지 않고 차아염소산나트륨 單獨으로 酸化할 때의 除去準은 H_2S 92.5%. NH_3 90%로 나타났다.
3. 차아염소산나트륨의 유효염소농도 100ppm 이상에 오존을 6, 11, 17ppm(5l/min)로 注入시킬 때는 H_2S 94.2, 96.3, 97.5%, NH_3 90.7, 94.0. 96.0%의 除去效率을 보인반면, 차아염소산나트륨을 添加하지 않고 오존單獨으로 酸化할 때의 除去效率은 H_2S 60.0, 57.5, 51.0% NH_3 52.8. 53,9, 55.0%로 나타났다.

This study was performed to remove hydrogen sulfide and amonia odor gas by packed tower with 5/8 inch pall ring. The removal efficiency of odor gas with various effective chlorine concentration oxygen injection ratio were shown by this experiment.
The experimental results as followed.
1. In the measuring of pressure drop of packed tower, it is found that pressure drop is 43mmAq/m at peak surface load. The data is in acceptable range of 50mmAq/m.
2. Removal efficiency of H_2S, NH_3 is 92. 5, 90.0%, when these are treated with NaClO. But removal efficiency of H_2S, NH_3 is 98%, 96%, when added 0_3 17ppm(5 l/min.) to NaClO(effective chlorine concetration of 120ppm).
3. Removal efficiency is very low with H_2S being 60.0, 57.5, 51.0% with NH_3 being 52.8, 53.9. 55.0% when these are treated with 0_3 of 6, 11, 17ppm, but removal efficiency is satisfactory with H_2S being 94.2, 96.3, 97.5% and NH_3 being 90.7, 94.0, 96.0% when NaClO(effective chlorine cencentraton above of 100ppm) is added.
