摘要:- 分別以陶粒、沸石-陶粒、兩種彈性纖維材料為填料，在有效體積為150 L的填充床中，對曝氣生物濾池（BAF）處理模擬城市微污染河水中氨氮和有機物的效果進行了試驗，并對比了4種填料的特點和運行效果。結果表明：兩種顆粒填料的氨氮硝化負荷要高于纖維填料，顆粒填料和纖維填料BAF的最佳HRT分別為1 h和1.5 h。在HRT為1 h時沸石-陶粒組合填料和陶粒填料的平均氨氮去除率分別為94.6%和93.7%，在HRT為1.5 h時兩種纖維填料的平均氨氮去除率分別為89.5%和92.6%，且顆粒填料對氨氮的去除主要集中在填料高度60~100 cm的部分。水力停留時間對兩種顆粒填料的進水壓力和出水濁度影響較大，而對纖維填料影響較小。在氣水比為2時，4種填料對氨氮和COD的去除效果好于氣水比為1和3時的去除效果。纖維填料BAF的投資成本更高，但運行成本要明顯低于顆粒填料BAF。
Abstract:- Treatment effects of biological aerated filters (BAFs) on ammonia nitrogen and organic matter in urban micro-polluted river water were explored. Ceramsite, zeolite-ceramic composite and two kinds of elastic fiber materials were utilized as fillers in the packed bed with an effective volume of 150 L, and characteristics and performances of the four kinds of fillers were compared. Nitration loads of ammonia nitrogen of the two granular fillers were higher than those of the fiber fillers, and the optimal HRTs of the granular filler BAF and fiber filler BAF were 1 h and 1.5 h, respectively. The average ammonia nitrogen removal efficiencies of zeolite-ceramic composite filler and ceramic filler were 94.6% and 93.7% respectively when HRT was 1 h, and those of two fiber fillers were 89.5% and 92.6% respectively when HRT was 1.5 h. In addition, the removal of ammonia nitrogen by the granular filler was mainly concentrated on the filler height of 60-100 cm. HRT had a great influence on the inlet pressure and effluent turbidity of the two kinds of granular fillers, but it had little effect on the fiber fillers. When gas-water ratio was 2, the removal efficiencies of ammonia nitrogen and COD of the four fillers were better than those when the gas-water ratios were 1 and 3. The investment cost of fiber filler BAF was higher, but the operational cost was significantly lower than granular filler BAF.
