  • 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。
    Abstract: The inexpensive slag was chosen as the best adsorption carrier by comparing the pollutants removal ability and adsorptive immobilized effect of three different adsorbing materials (slag, ceramsite and zeolite). PVA-SA mixed liquor (2% sodium alginate and 8% polyvinyl alcohol) was selected as embedding medium, and adsorption-embedment method which consist of pre-adsorption on slag, embedment and cross-linking was used to immobilize mixed nitrosation bacteria. The NH3-N removal by the PVA-SA-slag beads and influencing factors were studied. The results showed that the composite immobilized beads could maintain high microbial activity and the removal rate of NH3-N was about 80% after treating about 4 hours when the dosing ratio was 0.45, temperature was between 30~40℃, oscillation speed was 150 r/min and initial NH3-N concentration was 6 mg/L. This adsorption-embedment method has a certain practical significance for NH3-N removal, which provided a new technical reference for the purification of river water.
