The field experiment was performed on a swine farm located in
Changle (Fuzhou), Fujian in Southeast China. The farm kept nearly
10,000 pigs with a daily discharged effluent of about 150 m3. There
were more than 1000 m2 deserted sandy lands in the backyard,
giving sufficient space for the experimentation, as well as the possible
future development of a wastewater treatment system.
