Bilateral waste-water land-treatment research by China and the US EPA
The study was conducted to evaluate the rapid infiltration (R.I.) method of land treatment as a partial solution to wastewater treatment and reuse for the 0.45 billion cu m/yr (15.75 billion cu ft/yr) of safe irrigation water needed by the year 2000. Chinese environmental scientists and water supply managers are considering the use of the technology for diluting high concentrations of nitrate in the ground water while simultaneously recharging severely overdrafted aquifers. The wastewater used in the study contained synthetic organic compounds found on EPA's list of priority pollutants. During the development of EPA's Land Treatment Design Manuals, research was terminated before a thorough evaluation of the treatability of these compounds could be completed. Therefore, during the study, an evaluation of R.I. systems ability to treat selected priority pollutants as well as fecal coliform bacteria was carried out in the interest of RSKERL's research objectives. Even though the research was focused on operations to optimize the removal of various nitrogen species from primary effluent, the normal wastewater parameters of BOD, COD, SS, Total - P, and TOC were also studied. The volatile organic compounds most prominent in the wastewater, dichloroethene, dichloroethane, chloroform and carbon tetrachloride were also evaluated for treatability in the cooperative study.
