摘　　要：将高效节能脱氨技术应用到工业废水脱氨过程,可将废水中的氨氮降至15×10-6以下,达到国家的综合污水排放标准(GB 8978—96)中的I级标准。脱氨过程不仅可以产生12%~18%的氨水;而且也能得到含量为90%以上高浓度氨气,用于反应制得铵盐,实现了资源循环利用。蒸汽消耗小于105 kg/t(废水),单套装置的处理规模已达到600 m3/d。The efficient and energy-saving ammonia removal technology has been applied to industrial wastewater treatment.The unit can reduce ammonia-nitrogen content to less than 15 ppm,which meets level I of National Integrated Wastewater Discharge Standard(GB 8978—1996).In the mean time,the unit can produce ammonia water with an ammonia weight content of 12～18%(or ammonia of concentration higher than 90%),which can be used as raw material to produce ammonium salt.With this technology,resources can be recovered and ...
