摘　　要：污水污泥含有较高量的有机物及氮、磷等养分,经过减量化、稳定化、无害化处理后可作为农用肥料,对土壤及农作物都有明显的改善作用,因此可以说污泥农用是一种变废为宝的污泥资源化利用方式。然而,污泥中还含有重金属、有机污染物、病原菌等污染物质,因此农用的污泥一定要符合我国农业污泥标准(GB4284-84),避免使用过程中爆发土壤农用存在的潜在危险。Sewage sludge which contains large quality organic matters, nitrogen and phosphors can be used as farmer manure helpful to soil and form crop, by decreasing, stabilization and innocent treatment, Sludge using for farm is an approach of resources utilization. However, there are also heavy metals, organic pollutant and pathogenic bacteria in sludge, so it is necessary for sludge to measure up to agriculture sludge standards （GB4284 - 84）, in order to avoid the potential danger of sludge using for farm.
