Artificial wetland treatment system is an economical water purification system which has high potential in water purification ecology method. Many countries utilized this natural treatment system to solve their waste problems (for example, wastewater and solid waste) and well results were found with proven efficient. Recently, Taiwan has started developing the natural treatment system utilizing the self-purifying function of the natural surrounding by using the physical, chemical and biological reactions in soil, plants and microorganisms, to reduce the concentrations of pollutants produced by wastes. Eventually, all the pollutants can be eliminated to the harmless level to the environment and its organisms.
For better understanding the feasibility of artificial wetlands, we study the performance of artificial wetland system with its raw wastewater produced from its community household wastewater at Liao-Luo Village. Artificial wetland system is a natural purification system, no additional chemicals are needed. In addition, it can be easily operated and maintained, and can be used to treat wastewater with simple pollutants in school. Wetlands not only can be utilized to treat wastewater, but also for can be used for educational purposes.
The investigation periods in this work is from May 2008 to Dec.2008. The average of removal efficiency were as follows: BOD (52%), E-colis (79%), NH3 (74%). Total N (61%) and Total P (72%). In comparison with related literatures, we operated with higher removal due to the facts containing the lower organic loading and longer water retention time to decompose pollutants in solution.
To keep the Liao-Luo Village wetland¡¦s wastewater treatment function, periodical maintenance is performed. Besides moving grass and removing garbage, proper vegetables are planted in each treatment area are needed.
