The aim of this work was to study the biotreatability of industrial waste water as well as application of AOP Of FACCO or effective pretreatment. Because industrial waste water expressed biodegradability (BOD5/C D ratio was 0.40), biological treatment was the first choice. At the same time, in preliminary ready biodegradability assessment test, diluted broth degraded 65% as well it was not toxic to mixed bacterial culture of activated sludge. However, we had considered additional pretreatment method to be able to enhance biotreatability. FACCO procedure was optimised in batch reactor using different concentrations of 0.5 Fe2+, 0.2 H2O2, room temperatures. The highest treatment efficiency reached only 44% according to COD, but ready biodegradability of the sample increased (82%). FACCO was confirmed as possible method for pretreatment o industrial waste water for high COD contain, because it slightly enhanced biodegradability, it reduced organic pollution and formed products were nontoxic. We have focused our future work into a study on optimization of applied procedure for improving bio treatability of the industrial waste water.

Abstract


The aim of this work was to study the biotreatability of industrial waste water as well as application of AOP Of FACCO or effective pretreatment. Because industrial waste water expressed biodegradability (BOD5/C D ratio was 0.40), biological treatment was the first choice. At the same time, in preliminary ready biodegradability assessment test, diluted broth degraded 65% as well it was not toxic to mixed bacterial culture of activated sludge. However, we had considered additional pretreatment method to be able to enhance biotreatability. FACCO procedure was optimised in batch reactor using different concentrations of 0.5 Fe2+, 0.2 H2O2, room temperatures. The highest treatment efficiency reached only 44% according to COD, but ready biodegradability of the sample increased (82%). FACCO was confirmed as possible method for pretreatment o industrial waste water for high COD contain, because it slightly enhanced biodegradability, it reduced organic pollution and formed products were nontoxic. We have focused our future work into a study on optimization of applied procedure for improving bio treatability of the industrial waste water.
