Title
A study on the treatment of Cr containing wastewater by using aerobic biofilm
장성호Seong Ho Jang,박진식Jin Sick Park
Abstract
This study has been carried out to provide the basic data when biofilm with activated carbon was used for Cr(VI)-containing wastewater treatment. The results from this study are follows; Cr(VI) removal efficiencies with dosage of Cr(VI) indicated below 40% when Cr(VI) dosage was over 10㎎/ℓ at A and B reactor, and over 20㎎/ℓ at C reactor, no relation with volume loading rate. COD removal efficiencies with dosage of Cr(VI) were changed when Cr(VI) dosage was 10㎎/ℓ in case of 1.6, 3.2㎏·COD/㎥·day at A reactor, was 20㎎/ℓ in case of 1.6, 3.2㎏·COD/㎥·day at B reactor, was 25㎎/ℓ in case of 1.6, 3.2㎏·COD/㎥·day at C reactor. NH₄^+-N removal efficiencies with dosage of Cr(VI) were changed when Cr(VI) dosage was 1㎎/ℓ, 10㎎/ℓ at A, B reactor, not related with volume loading rate, was 20㎎/ℓ in case of 3.2, 4.8㎏·COD/㎥·day at C reactor.
