Abstract

The municipalities have been making serious investments in sewer system infrastructures based on regulations in environmental policies in our country in recent years and the number of wastewater treatment facilities is increasing day by day. The increase in the refined wastewater amount also brings an increase in the amount of sewage sludge generated. In Turkey, the average amount of sewage sludge produced daily as dry substance is around 1000 tons. However, there are some problems with its elimination. Since sewage sludge contains organic substances at high amounts and also macro and micro elements necessary for plant nutrition, it has a potential to be utilized as soil reclamation material or organic fertilizer. Therefore, this study was planned based on the idea that innovative solutions were needed to strengthen the positive sides of sewage sludge for its safe recycling in the ecosystem. The main purpose of the research is to make the material safer for utilization by producing humic acid from sewage sludge and applying it to soil instead of applying sewage sludge directly to the soil. For this purpose, humic acid was obtained from stabilized and dried domestic sewage sludge by alkali / acid extraction. Humic acid produced was applied to the soil and a pot experiment was carried out by growing grass plants. Humic acid applications were made with 4 replicates at 0, 50,100, 150, 200 kg da-1 soil levels. Grass plants height, fresh weight, dry weight, SPAD chlorophyll meter readings, total chlorophyll analysis values increased compared to the control, but only SPAD values were found to be statistically significant.

Özet

Ülkemizde son yıllarda çevre politikalarındaki düzenlemelere bağlı olarak kanalizasyon altyapılarına belediyeler ciddi yatırımlar yapmakta ve atık su arıtma tesislerinin sayıları gün geçtikçe artmaktadır. Arıtılan atık sular neticesinde ortaya çıkan arıtma çamuru miktarları da artış göstermektedir. Türkiye’de günlük kuru madde olarak üretilen arıtma çamuru miktarı ortalama 1000 ton civarında olup bertarafında sorunlar yaşanmaktadır. Arıtma çamurları önemli miktarlarda organik madde ve bitki beslenmesi için gerekli makro ve mikro elementler içerdiklerinden dolayı toprak ıslah materyali veya organik gübre olarak değerlendirilebilecek potansiyele sahiptir. Arıtma çamurunun ekosisteme güvenli bir şekilde geri kazandırılabilmesi için olumlu yönlerini güçlendiren yenilikçi çözümlere ihtiyaç olduğu düşüncesinden yola çıkılarak bu çalışma planlanmıştır. Araştırmanın temel amacı; arıtma çamurunu direkt toprağa uygulamak yerine arıtma çamurundan üretilen humik asidi uygulayarak kullanımını güvenli hale getirmeye çalışmaktır. Bu amaçla, stabilize edilmiş ve kurutulmuş evsel arıtma çamurundan alkali/asit ekstraksiyonu ile elde edilen humik asitin toprağa uygulanması ile çim yetiştirilerek saksı denemesi yürütülmüştür. Humik asit uygulamaları 4 tekerrürlü olarak 0, 50. 100, 150, 200 kg da-1 toprak düzeylerinde yapılmıştır. Çim bitkilerinin boy, yaş ağırlık, kuru ağırlık, SPAD klorofil metre okumaları, toplam klorofil analiz değerleri kontrole göre artış göstermiş ancak sadece SPAD değerleri istatistiksel olarak önemli bulunmuştur.
