Kömür Üretim Tesisi Atıksularının İleri Arıtım Prosesleri ile Arıtılarak Tekrar Kullanılabilirliğinin Araştırılması

Öz

Yeraltı madenciliği ile kömür üretimi gerçekleştirilen tesislerde üretim sırasında atıksu oluşumu kaçınılmazdır. Oluşan atıksuyun deşarj edilmesinden veya proses suyu olarak kullanılmasından önce uygun arıtma yöntemleri ile arıtılması gerekmektedir. Bu çalışma kapsamında yeraltı madenciliği ile kömür üretimi gerçekleştiren bir tesiste oluşan atıksuların fiziko-kimyasal ve membran prosesler ile arıtılarak kömür zenginleştirme tesisinde tekrar kullanılabilirliği incelenmiştir. Bu kapsamda atıksudan alınan numunelerde bulanıklık, ph, KOI ve AKM parametreleri incelenmiştir. Tesisin bulanıklık gideriminde toplam verimi %99,97, KOI giderim verimi %95,16, AKM giderim verimi ise %99,72 olarak hesaplanmıştır. İnceleme sonuçları arıtılan atıksuyun kömür zenginleştirme tesisinde tekrar kullanılabileceğini bununla birlikte çevresel ve ekonomik kazançlar sağlanabileceğini göstermiştir.

Investigation of Reusability of Coal Production Facility Wastewater by Treating with Advanced Treatment Processes

Öz

Wastewater formation is inevitable during production in facilities where coal production is carried out with underground mining. Before the wastewater is discharged or used as process water, it must be treated with suitable treatment methods. In this study, the reusability of wastewater generated in a facility that produces coal by underground mining was investigated for the coal beneficiation facility by treating with physico-chemical and membrane processes. In this context, turbidity, pH, COD and SS parameters were investigated in the samples taken from wastewater. The total efficiency of the plant in turbidity removal was determined as 99.97%, the COD removal efficiency as 95.16%, and the AKM removal efficiency as 99.72%. The results of the examination showed that the treated wastewater can be reused in the coal beneficiation facility, besides, environmental and economic gains can be achieved.
