摘要: Constructed wetlands are man-made systems that can be designed for the treatment of polluted water. One main mechanisms detoxification is considered to high microbial activity in nutrient and oxygen rich environment surrounding wetland plant roots. A simple small-scale model system was developed evaluate ability a constructed treat three types wastewaters. These were skimmed milk, raw sewage water containing concentrations zinc. Our results showed reduction all physicochemical parameters with exception phosphates. Extracellular protease production bacteria found at higher counts soils plants. We conclude our used some wetlands.
