  • 摘要: 通过比较炉渣、陶粒和沸石3种吸附基质对污染物的吸附去除效果和吸附固定微生物的效果,筛选出廉价易得的炉渣作为载体基质,同时以2%海藻酸钠(SA)和8%聚乙烯醇(PVA)混合溶液作为包埋剂,用吸附-包埋的复合方法固定具有亚硝化功能的混合微生物,并考察了该PVA-SA-炉渣小球去除河水中NH3-N的效果和影响因素。结果表明,当投加比0.45、温度30~40℃、振荡速度150 r/min和初始NH3-N浓度6 mg/L时,微生物可保持较高的活性,经4 h处理,复合固定化颗粒对河水中NH3-N去除率为80%左右。该吸附-包埋固定化方法对于去除NH3-N具有一定的实用意义,也为河流水体净化提供了新的技术参考。
