Abstract
Diplomatic relations between the United States and China, established in 1979, opened the door for development of 1985 bilateral environmental research and technology transfer between the USEPA's Robert S. Kerr Environmental Research Laboratory, Ada, Oklahoma, and China's Beijing Municipal Research Institute of Environmental Protection. The research was aimed at optimizing rapid infiltration treatment for nitrogen removal so that municipal wastewater could be used to recharge and improve nitrogen-rich, over-extracted ground-water aquifers. Complimentary research evaluated USEPA's selected priority pollutant volatile organics and fecal coliforms. During a three-year study period, several cyclic schedules of flooding and drying were systematically tested using duplicate lysimeters. Soils selected from a potential full scale site, lysimeter studies indicated that 16 days' flooding followed by a 5 day drying period provided the most efficient treatment. Nitrate and total nitrogen levels were consistently reduced to below 1.5 and 2.5 mg/l, respectively, while BOD, Kjeldal nitrogen, ammonia, organic nitrogen, and phosphorus were all reduced to less than 1.0 mg/l. Four volatile organic priority pollutants were slightly degraded during the winter but were significantly reduced during warmer months. The research also indicated that percolation of the wastewater through 370 cm of soil reduced fecal coliforms more than 6 orders of magnitude to below 6 counts per 100 ml.
