煤气吹脱解吸法代替水蒸汽蒸氨法的对比研究

Contrast research on coal gas stripping and adsorption process substitute ammonia stripping with water steam method

将研发的"煤气吹脱解吸法"(ZL200610019372.4)与传统的"水蒸汽蒸氨法"在脱除氨氮的原理、工艺、处理效果和经济环境效益等方面进行对比研究,结果表明:前者较后者工艺设备简单;煤气(吹脱介质)闭路循环;成本费用低;脱除氨氮效率高;勿须生化处理,氨氮即可达国家二级排放标准;具有很好地经济性和环境友好性。

This paper makes a compare with ＂ Coal Gas Stripping and Adsorption Process ＂ researched （ZL200610019372.4） and ＂Traditional Method of Ammonia Stripping with Water Steam＂ on the aspects of principle, technical process, the treatment effect, economic and environmental benefits of removing ammonia nitrogen. It is found that, comparing with the latter, the equipment of former is more simple; Coal gas as Stripping medium is closed circuit; the cost is lower; the efficiency on removing ammonia nitrogen is higher; NH3 -N in the effluent can reach the national discharging standard two without biochemistry processing. It has the efficiency and environmental friendliness.
