| 摘 要： | 目的]研究以过磷酸钙为填料的吸附塔对间歇通风条件下挥发氨气的吸附效果。方法]以过磷酸钙填料的吸附塔为试验装置,吸收塔主体以一定高径比的PVC圆管构建,首先以氨水为氨气挥发源,研究了相同过磷酸钙装填量时,吸附塔高径比对氨气吸附效果的影响,进而选定高径比为9.9的吸附塔,对经过碳氮比调整的猪粪和鸡粪堆体,选择通风静堆条件进行了废气吸附试验。结果]在一定的挥发速度下,吸附塔中的过磷酸钙颗粒可有效地吸附气流中的氨气,吸附效果随吸附塔高径比增加而增大,高径比在1.1以上时,吸附效果均可达到90%以上;使用高径比9.9吸附塔,占堆体重量8%左右的过磷酸钙装填量基本上能完全吸附猪粪、鸡粪堆肥过程中释放出的氨气。结论]该研究结果为过磷酸钙吸附塔在堆肥废气处理中的应用提供了参考依据。

| Abstract: | Objective] This study aimed to investigate the adsorption properties of the adsorption tower filled with calcium superphosphate on ammonia volatilized with aeration.Method] Adsorption tower filled with calcium superphosphate was adopted as experimental apparatus,which was constructed by poly vinyl chloride (PVC) circular tubes.With hartshorn as the source of ammonia volatilization,the effect of different ratios of height to diameter of the tower filled with equal amount of calcium superphosphate on ammonia adsorption was investigated.In addition,adsorption tower with height-diameter ratio of 9.9 was selected to adsorb the ammonia emitted from the composting systems of pig manure and chicken manure with optimized and regulated carbon-nitrogen ratio.Result] Under certain volatilization rate,calcium superphosphate particles in the adsorption tower could effectively adsorb the ammonia,and the adsorption efficiency was enhanced with the increase of height-diameter ratio,which could reach above 90% with height-diameter ratio of more than 1.1; the ammonia emitted from composting systems of pig manure and chicken manure with optimized and regulated carbon-nitrogen ratio could be completely absorbed using adsorption tower with height-diameter ratio of 9.9 filled with calcium superphosphate accounting for about 8% of the weight of composting materials.Conclusion] Experimental results of this study provided reference for the application of adsorption tower filled with calcium superphosphate in the treatment of waste gas emitted from composting materials. |
