Degradation and biodegradability enhancement of highly concentrated organic matter in the form of COD and color in ADSW treatment with microwave assisted ozone, and hydrogen peroxide was studied in laboratory scale experiment. The effects of corresponding effective factors, ozone (60 liter), H 2 O 2 (1ml of H2O2/100 ml ADSW) dose, MW treatment time (3min) optimized and used in experiment. The performance of all the three treatments was compare and measured in terms of percentage color, COD and BOD variation. For ozone treatment at 60 liter dose, reduction of 37.01% COD, color 64.75% and increase in BOD 64.75% was observed. Ozone in combination with H 2 O 2 remove 41.93% COD and color 70.28%. Alone MW treatment removes 19.35% COD remove and increase in BOD 20%. Combine ozone, H 2 O 2 and MW treatment shows more reduction COD 49.19%, color 36%, and BOD increase up to 56%, which shows the enhancement in biodegradability of ADSW.

Advanced oxidation processes (AOPs) are powerful for degrading most organic and inorganic compounds, which led the way in the treatment of wastewater and so has attracted great attention. In present study shows, COD reduction efficiency of anaerobically digested distillery effluent by Electro-Fenton (EF) process, as it is one of the AOPs, evaluated in lab scale experiments. An electrochemical batch reactor furnished with two iron electrodes, connected parallel to each other and used to carried out the experiment. The E-Fenton process was studied for optimization of power consumption, agitation speed and the reaction time under different pH conditions (3.0, 5.0 and 7.0). In this process COD reduction up to 24.9 % was achieved at 18 W power consumption in acidic pH 3 with 500 rpm agitation speed and within 120 min reaction time. Electro-Fenton process can successfully apply for the treatment of ADSW having high organic content in the first stage only, because organic pollutants does not degrade completely and further treatment is necessary before discharging it into natural ecosystem.
