【摘要】 以腐殖生物填料中有机质成分随使用过程的变化情况及溶解氧对填料释放物质的影响研究为基础,对长春市某采用腐殖活性污泥法处理粪便污水的有机固废处理厂各反应池内污泥中有机质成分进行了检测分析。结果表明:腐殖生物填料在使用过程中,其有机质质量分数不随质量消耗而减少,基本维持在308 g/kg,其中腐殖酸、富里酸和胡敏酸分别维持在143、64、79 g/kg左右;溶解氧质量浓度为0.5mg/L时腐殖生物填料释放含羟基和羧基官能团有机物种类多于溶解氧质量浓度为2.0 mg/L时;沿有机固废处理厂污泥回流及内回流方向,污泥中富里酸质量分数及腐殖酸占污泥有机质比例表现出上升趋势,污泥中富里酸质量分数大于胡敏酸质量分数。更多还原

【Abstract】 The organic constituents in reaction tanks of an organic solid waste treatment plant in Changchun,which disposal of fecal sewage by using humus activated sludge process,were detected and analyzed with the use process and dissolved oxygen(DO) affected the release matters of pellets.The results showed that,the mass fraction of organic matter in humic biological pellets,basically unchanged with its own consumption,maintained at the level of 308 g/kg throughout the process of using,humic acids,fulvic acid and humic acid maintained at 143 g/kg,64 g/kg and 79 g/kg,respectively.More kinds of organic matters which containing hydroxy and carboxyl were released when concentration of DO was 0.5 mg/L,compared with 2.0 mg/L.Rising tendencies of the mass fraction of fulvic acid and proportion of humic acids,as well as higher mass fraction of fulvic acid than humic acid,were detected along the return and inner return direction of sludge of the plant.更多还原
