A highly porous nylon biocarrier was developed to support immobilized bacteria in bioreactors used to treat liquid wastes. Porosity analyses and scanning electron microscopy showed microbial colonization of accessible pores typically in the range of 100 to 1,200 (mu)m, with some as large as 3.9 mm. A bench-scale packed-bed reactor achieved a p-nitrophenol (PNP) removal rate of 5.95 kg of PNP m(sup-3) day(sup-1) for wastes containing 1,200 mg of PNP liter(sup-1). Complete mixing of the biocarrier bed to remove excess surface biomass was routinely achieved with simple air injection. These porous polymer biocarriers are promising as microbial supports in liquid-waste treatment and bioremediation applications.
一种高多孔尼龙生物载体被开发出来，用于支持生物反应器中固定化细菌，以处理液体废物。孔隙率分析和扫描电子显微镜显示，微生物可在可及的孔中定植，通常在 100 至 1200（μm）范围内，有些孔可达 3.9 毫米。在一个台式填充床反应器中，对于含有 1200 毫克 PNP 升(sup-1)的废物，p-硝基苯酚（PNP）的去除率达到了 5.95 千克 PNP 立方米(sup-3)天(sup-1)。通过简单的空气注入，可常规实现生物载体床的完全混合，以去除多余的表面生物量。这些多孔聚合物生物载体在液体废物处理和生物修复应用中作为微生物支持物具有广阔的前景。
