英文摘要	This paper introduces the first production-scale ecological engineering slow-rate infiltration land treatment system (SR-LTS) with dominant covering vegetation of forest for the treatment and reutilization of wastewater in China. Vegetation includes larch (Larix principis rupprechetii Mayr.), pine (Pinus sylvestris L. var mongolica Litv.) and poplar (Populus xoeichenesis Bal Lin II) besides primary grasses growing originally and naturally and a small area of fruit trees for comparative studies. Operation results and process design with emphasis on hydraulic loading rates are presented after 3 yr successful operation. The system is located north of Huolinguole city, in Inner Mongolia, China, where water is in serious shortage due to much less precipitation (389 mm yr(-1)) than evaporation (1495 mm yr(-1)) and where trees can not grow normally without irrigation. The reutilization of wastewater as an important water resource for irrigation and forestation must be achieved simultaneously in the course of wastewater treatment in the area. The SR-LTS was therefore designed and operated as a utilization type in order to irrigate a maximum area of land. It occupied a field area of 880 ha for a daily treatment flow of 10 000 m(3) of municipal wastewater from the whole city of about 50 000 people. The system consists of five sub-systems with the main technological treatment process of 'wastewater --> primary treatment --> LTS' and 'wastewater --> primary treatment --> (winter) storage in reservoir --> LTS'. Under an average hydraulic loading rate of 41.5 cm yr(-1), the system performed well. Concentrations of BOD5, COB, total nitrogen and total phosphorus in percolation water were in the range of 1 to 3, 20 to 30, 0.5 to 1.5 and 0.03 to 0.06 mg l(-1) and their removal rates were greater than 86, 65, 85 and 84%, respectively.
