摘　　要：经好氧发酵后的污泥发酵产物可作为草坪基质进行资源化利用。以传统生产模式为对照,结合污泥发酵产物应用于草坪基质的工程案例,对运行成本和效益进行收支分析。分析结果表明,采用污泥发酵产物作为草坪基质时总成本较传统生产模式降低约10%,税后利润和净现值均为传统生产模式的3.3倍,因此污泥发酵物应用于草坪生产从经济性上是显著可行的。Composted sewage sludge can be used as lawn substrate. Compared with traditional lawn production, the operation cost and benefit of an engineering case using composted sewage sludge as lawn substrate were analyzed. The results indicated that the total cost of using composted sewage sludge as lawn substrate was reduced by 10% , both profit after tax and net present value were 2.3 times higher than those of traditional lawn production. From an economic point of view, applying composted sewage sludge to lawn production is definitely feasible.
