摘　　要：利用准好氧矿化垃圾柱,通过室内模拟试验,采用正交试验方法研究准好氧矿化垃圾柱处理渗滤液的最佳工艺参数。研究表明,本试验最佳工艺参数为水力负荷0.023L/kg矿化垃圾.d,进水周期24h,有机负荷0.33g/kg矿化垃圾.d,氨氮负荷0.028g/kg矿化垃圾.d。其中水力负荷是影响矿化垃圾柱处理效果的关键因素。Adopting semi-aerobic aged-refuse-based bioreactor, orthogonal simulative tests were conducted in laboratory to determine the optimum process parameters of semi-aerobic aged-refuse-based bioreactor treating leachate. The results showed the optimum parameters consisting of hydraulic loading rate as 0. 023 L/kg aged-refuse · d, feeding frequency as 1/24 h, organic loading rate as 0. 33 g/kg aged-refuse · d, NH3-N loading rate as 0. 028g/kg aged-refuse · d, of which the hydraulic loading rate was the key factor.
