Abstract: Turtle-breeding wastewater and domestic fecal sewage were treated by means of soil cultivating system. Results indicated that more than 50% COD_cr and BOD_5 of wastewaters were removed, removal rates of NH_4^+ -N could reach about 70%-80%, but PO³_4^- could not be removed. The thesis analyzed functional mechanisms for pollutants and put forward main elements affecting treatment efficiencies, thus provided conditions for further research.
