Selçuk Üniversitesi Kampüsü atıksuyu arıtım projesinin hazırlanması

Selçuk Üniversitesi Alaeddin Keykubad Kampüsü atıksu özelliklerinin belirlenmesi ve uygun arıtım projesinin hazırlanması amacıyla bir yıl süresince günde 4 defa olmak üzere Mart 2001-Şubat 2002 tarihleri arasında atık su numunesi alınmıştır. Kampus kanalizasyon sisteminin çıkış noktasından alman numunelerde fiziksel ve kimyasal parametrelerin ölçümleri yapılmıştır. Atıksu debisi ve buna bağlı olarak atıksu arıtım maliyetleri tespit edilmiştir. Beş farklı biyolojik arıtma prosesi için, debi-ilk yatırım maliyeti, debi-toplam işletme ve bakım maliyetleriyle debi-arazi ihtiyacı hesap edilmiştir. Bunun yamsıra, değişik firmalardan alınan atıksu arıtma tesisi proje teklifleri de hem maliyet analizi hem de proses seçimi esnasında değerlendirilmiştir. Kampus şartları dikkate alındığında, atıksuların arıtımı için stabilizasyon havuzu kullanımı, enerji ve işletme maliyetlerinin azlığı ve basit işletim kolaylığı gibi avantajlar sağlamaktadır. Diğer tarafdan, düşük arazi gereksiniminden dolayı mekanik havalandırmalı lagünün, stabilizasyon havuzuna alternatif olduğu ve arıtılmış atıksuların kampüsteki yeşil alanların sulanmasında kullanılabileceği ortaya konulmuştur.

Wastewater treatment project of Selçuk University Campus wastewater

Samples to determinate wastewater characteristics and appropriate wastewater treatment project of Selçuk University, Alaeddin Campus were taken during one year, from March 2001 to February 2002, four times in a day. Samples have been provided from the manhole of Campus sewage system. Physical and chemical parameters were analysed. However, wastewater flow rate and with related treatment costs, that must be used in project phase, have been investigated after chemical and physical analyses. Flow rate- versus construction cost, operation and maintenance costs and land requirement for five different biological treatment processes have been estimated. In addition, some wastewater treatment processes suggested by several companies have been also examined and compared with the value of the graphics methods. The results indicate that, by taking the specific conditions of Alaeddin Keykubad Campus into account, employing stabilization pond system to treat wastewater of Campus has the advantages of being economical of energy, easy to operate, and low operation costs. Also mechanic aerated lagoon should be alternativ system to stabilization pond with less land requirement. Purified wastewater would be used for irrigation of campus green field.
