The furrow irrigation tests were done to estimated the efficiency of the HRT(Hydraulic Retention Time) and landfill leachat collected from Dalian Maoyimgzi Municipal Solid Waste Landfill, which contained high level of COD (Chemical Oxygen Demand, 3.8 × 10⁴ mg·L^–1), TOC (total carbon, 4.8 × 10³ mg·L^–1), TN(total nitrogen, 2.9 × 10³ mg·L^–1) and SS (Suspended Solids, 6.5 × 10² mg·L^–1), using the reed (phragmites) cultivated onland located in south area of Dalian Jiaotong University. The results showed that: 1) The TN concentration was decreased from 9.8 × 10² mg·L^–1 in the landfill leachate to 7.6 × 10² mg·L^–1 in the soil water, and the 22.4% of the removal rate; 2) The TOC concentration was decreased from 4.8 × 10³ mg·L^–1 in the landfill leachate to 1.0 × 10³ mg·L^–1 in the soil water, and the 79.2% of re- moved rate; 3) The water concentration in the soil was no significant difference of irrigation between the water and the landfill leachate; 4) ΔHRT was 2.1 hours in irrigation 39 L of the water and landfill leachate and 1.3 hours in the 9 L.
