| 摘 要： | 本试验将纳米凹凸棒土复合亲水性聚氨酯泡沫和海绵铁填料介入传统潜流湿地土地处理系统,以生活污水为处理对象,通过室外中试试验,与传统的土地处理系统对比,考察了该复合填料对传统土地处理系统的强化作用。研究表明,在较高的表面负荷下,传统填料和复合填料最初出水总磷都能达到很好的除磷效果,分别达到了国家《城镇污水处理厂污染物排放标准》(GB 18918-2002)的一级B标准和A标准。复合填料的出水总磷更低,更能有效缓解水体富营养化。

| Abstract: | This test used nano-attapulgite compounded hydrophilic polyurethane foam and sponge iron packing traditional land treatment system with undercurrents to treat the sewage through the outdoor pilot scale fest.It investigated the reinforcement of composite land treatment system.And the traditional land treatment system was also investigated at the same time.Results showed that in a high surface loading,the traditional packing and compounded packing systems both achieved a good effect.TP in the ultimate effluen... |
