| Treatment Of Wastewater From Resultıng Of Rural Area In Ankara Cıty By Usıng Natural Treatment (Constructed Wetland System)
Nowadays, complex and expensive systems are built and therefore operating and total costs are increasing together with the need for qualified employee need for operating these systems because the refining systems have been developing rapidly. In recent years, natural treatment systems are introduced as alternatives for these expensive systems because of being cheap and respective to the environment. Among other natural treatment systems, constructed wetlands are preferred for needing less maintenance, low operating cost and initial investment and high performance in treatment waste water. These sustainable purifying systems are ideal for especially for rural areas.
Suitability of constructed wetlands for Turkey and problems faced are issued at a pilot application in the province Ankara. Constructed treatment plant that is placed in Akdoğan village of Kızılcahamam-Ankara is accepted as the pilot plant. For 8 months, biochemical oxygen demand (BOD), chemical oxygen demand (COD), amount of suspended solid (SS), nitrogen, phosphorus and pathogen removal is inspected. During this time, there has been 41% to 46% of COD removal, 66.6% to 72% of BOD removal, 74% to 80% of ASS removal, 85% to 86% of nitrogen removal, 52% to 67% of phosphorus removal, 90% to 93% of faecalis coli removal and 91% to 94% of total coli removal. Beside of being economical, these systems are viable especially in the rural regions, because they are considerably efficient in impurity and pathogen microorganism removal. But before designing these plants, properties of region environment and the waste water itself.
