【摘要】 本试验研究了生物渗滤床对养殖废水的处理效果,同时对生物渗滤床与常规好氧生物方法处理养殖废水的技术经济参数进行对比分析。结果显示:生物渗滤床对养殖废水具有很好的处理效果,出水COD平均浓度120mg/L,明显优于《畜禽养殖业污染物排放标准》的指标要求(COD≤400mg/L);可实现全自动控制、基建投资费用可节省45%、运行能耗可节省86%,吨水处理费用仅为0.22元。技术经济分析结果表明,生物渗滤床是一种高效、稳定、低成本的养殖废水处理新技术,完全能够取代常规好氧生物处理方法。更多还原

【Abstract】 A technological and economical comparison between the biological filter bed and the traditional aerated biological oxidation process was carried out.The result showed that biological filter bed is quite effective in treating livestock wastewater.Because the average effluent COD is 120mg/L,which is obviously better than the 400mg/L one required in"discharge standard of pollutants for livestock and poultry breeding".Furthermore,the biological filter bed is automated,and can save 45%of the cost for construction,86%of energy consuming.The cost of wastewater treatment is only 0.22 yuan per ton.The technological and economical analysis indicated that biological filter bed is a efficient,stable,low cost and novel process,and is a prospective substitution for traditional aerated biological oxidation process in treatment of livestock wastewater.更多还原
