Türkiye’de Bir Boya Endüstrisi Atıksu Arıtma Tesisi için Çevre Dostu Teknolojinin Araştırılması

Boya üretim prosesi; Türkiye’de birçok olumsuz çevresel etkiye sahiptir. Bu etkilerden birisi atıksu arıtımıdır. Boya endüstrisi atıksuyu, yüksek miktarda zehirli kimyasal maddeleri, biyolojik olarak parçalanmayan bileşikleri, pigment ve mikroorganizmaları içerir. Sonuç olarak atıksudan; renk, mikroorganizma ve organik madde (KOI) giderimi için ileri bir arıtma prosesine ihtiyaç duyulmaktadır. Atıksuyun yüksek organik madde içeriği, yeterli arıtılmaması durumunda; alıcı ortamda yaşayan organizmalar ve ekosistem için ciddi çevre sorunlarına ve kirliliğe neden olur. Bu kapsamda, uygulanacak arıtma prosesi, çevreye en az zarar verecek şekilde seçilmelidir. Bu çalışmada, Türkiye’deki bir boya endüstrisi atıksu arıtma tesisi için; elektrokoagülasyon (Senaryo-1), Fenton prosesi (Senaryo- 2) ve membran distilasyonu (Senaryo-3) içeren üç adet arıtım senaryosu oluşturulmuştur. Üç senaryo için, Fine-Kinney yöntemiyle çevresel etki değerlendirme gerçekleştirilmiştir. Yatırım yapılmadan önce, en çevre dostu teknolojinin seçilmesi amaçlanmıştır. Değerlendirme sonuçları, Senaryo- 2’nin, 556 toplam etki puanıyla en düşük çevresel etkiye sahip olduğunu göstermektedir. Senaryo- 1 en yüksek toplam etki puanına sahiptir (756). Senaryo 3’e ait toplam etki puanı 637’dir. Değerlendirme sonuçlarına göre, Fenton Prosesi, Türkiye’deki bir boya endüstrisi atıksu arıtma tesisi için en çevre dostu arıtma teknolojisidir.

Investigation of Environmental-friendly Technology for a Paint Industry Wastewater Plant in Turkey

Paint manufacturing process has several unfavorable aspects to theenvironment in Turkey. One of these impacts is wastewater treatment. Paintwastewater contains huge amounts of toxic chemical substances, bio refractorycompounds, pigments and microorganisms. So, advanced treatmentrequirement is available to dispose of colour, microorganisms and chemicaloxygen demand (COD). The high organic content of wastewater causes seriousenvironmental challenges and contamination for the living organisms and theecosystem in the receiver media unless it is treated adequately. In this context,the treatment process to be implemented should be preferred in such a way asto give the least damage to the environment. In this study, three treatmentscenarios that contain electrocoagulation (Scenario-1), Fenton process(Scenario-2) and membrane distillation (Scenario-3) have been created forwastewater treatment facility of a paint industry in Turkey. For three scenarios,environmental impact assessment has been carried out with Fine-Kinneymethod. It is aimed to choose best environmental technology beforeinvestment. The evaluation results revealed that Scenario-2 has the lessenvironmental impacts that total impact value is 556. Scenario-1 has thehighest total impact value as 756, relatively. Total impact value related toScenario-3 is 637. According to the evaluation results, Fenton process is thebest environmental-friendly treatment technology for wastewater treatment ofa paint industry in Turkey.
