Avrupa Ülkelerinde Çamur Bertaraf Stratejilerine Etki Eden Faktörler

Abstract

Bu çalışmada Avrupa ülkelerinde üretilen toplam arıtma çamuru miktarları ve çeşitli faktörlere göre çamur bertaraf stratejilerinin tercih nedenleri araştırılmıştır. Çalışmada Avrupa İstatistik Kurumu ve literatürden alınan veriler seçilirken küresel şartlar göz önünde bulundurulmuştur ve en doğru veri setleri seçilerek değerlendirme yapılmıştır. Avrupa ülkelerinde birincil, ikincil ve üçüncül arıtmadan kaynaklanan arıtma çamuru üretimi kişi başına kuru ağırlık ortalama 42 g/kişi.gün ya da 15,26 kg/kişi.yıl olarak hesaplanmıştır. Arıtma çamuru bertaraf yöntemlerinin maliyetleri, ülkelerin yüzey alanları, milli gelirleri ve enerji ihtiyaçlarına göre karşılaştırma yapılmıştır. Yüzey alanı düşük olan ve çamur miktarı yüksek olan ülkelerin arıtma çamuru bertaraf yöntemi olarak yakmayı tercih ettikleri görülmesine rağmen bertaraf seçiminde ülkenin milli geliri ve enerji ihtiyacının da yöntem seçiminde oldukça etkili olduğu belirlenmiştir. Çalışma bütünüyle incelendiğinde arıtma çamurunun bertaraf yöntemi seçiminde faktörlerin tek başına önemli oranda benzer sonuç verdiği bulunmuştur ancak daha doğru bağlantılar kurulabilmesi için bütün olarak hepsinin ele alınması gerektiği görülmüştür.

Factors Affecting Sludge Disposal Strategies in European Countries

Abstract

In this study, the total amount of sewage sludge produced in European countries and the reasons for choosing sludge disposal strategies according to various factors were investigated. In the study, global conditions were taken into consideration while selecting the data taken from the European Statistical Institute and the literature, and the most accurate data sets were selected and evaluated. Sewage sludge production from primary, secondary and tertiary treatment in European countries is calculated as an average of 42 g/person.day per capita dry weight or 15.26 kg/person.year. The disposal methods were compared according to the costs, surface areas, national incomes and energy needs of the countries. Although it is seen that countries with low surface area and high amount of sludge prefer incineration as treatment sludge disposal method, it has been determined that the national income and energy needs of the country are also very effective in the selection of the method. When the study was examined in its entirety, it was found that the factors in the selection of the treatment sludge disposal method alone gave significantly similar results, but it was seen that all of them should be considered as a whole in order to establish more accurate connections.
