ABSTRACT
Artificial or constructed wetlands (CW) have been successfully used for the treatment of surface runoff, landfill leachates, polluted river water, and wastewater. In the practical application, CWs can be used to remove many types of pollutants including nutrients, organic chemicals, suspended solids (SS), trace elements, pesticides, and even inorganic chemicals from different wastewaters and river water. The Kaoping River Rail Bridge Constructed Wetland (KRRBCW) has become one of the most important and successful multi-functional CWs in Taiwan. The polluted stream water also result in the deterioration of the Kaoping River water quality, which is a receptor of the Ju-Liao Stream. The main goal of the association is to assure that the KRRBCW can play an important role in water purification, water quality improvement, wastewater polishing, environmental education, ecosystem rehabilitation, and recreation. Because of the inadequate discharges of industrial, domestic, and agricultural wastewaters into the stream, the Ju-Liao Stream is a highly polluted local river in Kaohsiung City.
