CONSTRUCTED WETLANDS FOR MUNICIPAL WASTE WATER TREATMENT; CASE STUDY OF ÇAKIRBEYLİ VILLAGE (original) (raw)
Recently, it has been carrying out a lot of researches and applications on waste water treatment and using this kind of water in many countries. Advanced technological equipment is using with high costs for the treatment of waste water and recycling or not harming the environment. However, these systems have very high costs for both building and operation with qualified labor needed for operation and also maintenance. In consequence, the ‚Constructed wetland systems‛ are recommended as alternative solution to treat the waste water especially for small town and villages. The constructed wetlands are simple systems simulating the nature like swamps. And they have embodied all procedure in the typical or conventional treatment to refine waste water. It can be summarized that the advantages of these types of systems are being simple and low cost of building; low energy requirement and operating cost; not need very high qualified labor, and in accordance with environment. The only particular disadvantage of constructed wetland is that occupying vast lands. In this study, a constructed wetland build in Torbalı-Çakırbeyli village of İzmir province of Turkey was monitored between 2005 to 2008 years and the obtained data was assessed. The four years average removal performances of this system are; 57.36 and 73.61% for Chemical Oxygen Demand (COD); 56.18 and 79.25% for Biochemical Oxygen Demand (BOD5); 56.62 and 91.04% for Total Suspended Solids (TSS); 26.45 and 48.39% for Total Nitrogen, 41.38 and 54.45% for Total Phosphorus. Finally, the value of parameters like BOD5, COD, TSS and pH found that they are below the threshold values of Water Pollution Control Regulation (WPCR) of Turkish Government.
