摘　　要：结合某工程实例对浓缩液回灌处理进行研究,考察了将浓缩液进行回灌处理的可行性,并测定了浓缩液回灌渗入量和影响半径。结果表明,将浓缩液在垃圾堆体上进行回灌处理是可行的。试验中,1~#和2~#回灌塘的初始入渗量分别约为140和80 m^3/d,其稳定入渗量分别为(28～30)和(14～16)m^3/d;1~#和2~#回灌井的初始入渗量分别约为7和4 m^3/d,其稳定入渗量分别为(5～6)和(3.5～4)m^3/d;1~#和2~#回灌塘的回灌影响半径均小于50 m,1~#和2~#回灌井的回灌影响半径分别为(20～30)和(10～30) m。The recirculation treatment of landfill leachate concentrate was studied with an engineering case. The feasibility of the recirculation treatment was investigated, and the infiltration rate and influence radius of the concentrate recirculation were determined. The results show that it is feasible for the landfill leachate concentrate to be recirculated within waste pile. In the test, the initial infiltration rates of 1^# and 2^# recirculation ponds are 140 m^3/d and 80 m^3/d, and the stabilized infiltration rates are 28 to 30 m^3/d and 14 to 16 m^3/d. The initial infiltration rates of 1^# and 2^# reeirculation wells are 7 m^3/d and 4 m^3/d, and the stabilized infiltration rates are 5 to 6 m^3/d and 3.5 to 4 m^3/d. The influence radii of 1^# and 2^# reeireulation ponds are less than 50 m, and those of 1^# and 2^# recirculation wells are 20 to 30 m and 10 to 30 m.
