【摘要】 分析了含锌高浓度氨氮废水和催化裂化含硫废水的水质,将两种废水混合进行一定的调配后,使其中重金属污染物以ZnS的形式沉淀并过滤出来,Zn2+的去除率达9999%;过滤液进入汽提装置以去除其中的氨氮和硫,重点对该废水的汽提性能作了考察。更多还原

【Abstract】 The water quality of wastewater containing high concentration ammonia,nitrogen and zinc is analyzed. The wastewater containing ammonia nitrogen was mixed with wastewater containing sulfide to form precipitation ZnS that is filtrated. The rate of removal of Zn 2+ can reach 99 99%. The filtrate was emptied into steam stripping unit to remove ammonia nitrogen and sulfide. The emphasis was laid on the inspection of the performance of steam stripping for the wastewater.更多还原
