Description
技术领域 本发明涉及一种用于有机废水处理工艺的复合纳米生物介质，更具体地说，涉及一种适合于处理城市生活污水及各种有机废水的生物氧化、吸附脱色、硝化等的纳米生物介质。
背景技术 在现有污水处理技术中，比较典型、应用较广的处理方法有UNITANK、生物膜、SBR、传统活性污泥法、三沟式氧化法以及这些工艺的结合、改良型，虽然各具特色，但都涉及到微生物的应用及为其提供有效工作的工艺条件。微生物技术应用于有机废水的处理已有较长时间，日本于20世纪80年代末开始利用微生物降解粪便，此后，环保界开始通过各种方法，利用各种微生物去处理有机污水，涌现出了一大批专用微生物菌剂，但微生物的降解效果却仍然不够理想，主要表现在投加的外源微生物活性低，再生能力弱，需要不断补充，其主要原因除了微生物菌群本身比较单一、复合菌群少、分解能力弱外，另一个关键因素是没有可反复再生的、性能良好的吸附、固定微生物的介质，致使投加的外源微生物极易随水漂流，影响了专用微生物作为优势种群的数量。目前应用的介质主要有陶粒、聚苯乙烯球粒、组合介质、弹性立体介质等，这些产品由于比表面相对较小，功能单一，有一定的吸附脱色效果，但都很难达到微生物再生的要求，且成本较高，限制了其应用。
发明内容 本发明的目的在于提供一种适合于各种有机废水处理的具有较低成本、低密度、大比表面积、大孔隙率、强亲水性及较强生物氧化、硝化、吸附脱色能力、使外源专用微生物快速再生并提高其活性的纳米复合生物介质。
为了达到上述目的，本发明提供了如下的技术方案：研制一种纳米复合生物介质，其成分和重量百分含量为：基材48％～68％，芯材2％～4％，造孔剂3％～7％，水泥胶结剂35％～45％，所述的基材为纳米活性炭、微孔膨胀蛭石、纳米孔海泡石、纳米孔沸石、微珠粉煤灰或其类似物的一种或多种任意比例的混合物，所述的芯材为颗粒活性炭，所述的造孔剂是碳酸氢铵，将所述各成分定量粉碎至粒度为100～200目、混合、喷30～40℃热水造球、常温凝结、固化，得粒径4～50mm，微孔直径20～200μm，比表面积50～200m2/g的复合纳米生物介质。另外，本发明复合纳米生物介质的表观密度1.0～1.5g/cm3，孔隙率35～55％，比表面积50～200m2/g，破碎磨损率＜2％，酸溶率＜2％，碱溶率＜1％。这类复合纳米生物介质主要化学成份为SiO2、Al2O3、CaO、MgO、K2O、Fe2O3等不含对人体有害的重金属及其它有害物质，孔隙率高，是理想的生物介质。在造球中，使用轻质芯材进行造球，芯材为多孔有机或无机物质，如颗粒活性炭等，用以降低介质的密度，芯材的粒度为介质粒度的1/3左右。
本发明较好的技术方案是：复合纳米生物介质的基材中的各成分及重量百分含量为：纳米活性炭20％～30％、微孔海泡石16％～27％、纳米沸石10％～20％，微珠粉煤灰25％～40％。在所述的基材中，包括造孔剂及水泥胶结剂，复合纳米生物介质中的物质化学成分及含量为：C5％-20％、SiO2 30％-33％，Al2O313％-14％，CaO 26％-30％，MgO 3％-5％，K2O 1％-2％，NO20.1％-0.3％，Fe2O3 4％-6％，Pb、Zn、Cu少量。在该种情况下，介质对微生物及有机微粒有良好的吸附、固定效果且氨氮硝化性能优、脱色能力强、成本低，而且其本身能够反复再生，同时该种介质能够根据不同污水的色、味性质及BOD、COD、悬浮物含量适当调整物料配方，以达到除色、去味、加强微生物降解有机物的工艺效果。
本发明复合纳米生物介质的应用：用于各种有机废水的处理，吸附、固定、再生微生物并作为微生物降解有机物的反应界面进行生物氧化、硝化、脱色、除味等。本发明纳米复合生物介质应用于生物膜工艺处理城市生活污水，能确保出水CODCr≤40mg/L，BOD5≤10mg/L，SS≤10mg/L，NH3-N≤10mg/L，处理后的污水达国家污水排放一级标准。
与现有技术相比，本发明具有以下明显的优点：所述的纳米复合生物介质与陶粒、聚苯乙烯球粒、弹性立体介质及其它复合介质相比，其生产成本为陶粒的50％，聚苯乙烯球粒的60％，组合介质的70％，弹性立体介质的80％，介质挂膜效率为陶粒的110％，聚苯乙烯球粒的150％，组合介质的180％，弹性立体介质的200％，其对微生物的吸附、固定效果及生物氧化、硝化、脱色除味能力明显优于陶粒，同时能够根据污水的性质及污染物含量适当调整物料配方，以达到理想的艺效果。
