Celem badań było określenie skuteczności podczyszczania odcieków składowiskowych z wykorzystaniem koagulacji, ozonowania i reakcji Fentona.
The objective of the research was to study coagulation-flocculation, ozonation and Fenton’s process pretreatment on a stabilized landfill leachate. The leachate came from a municipal sanitary landfill, located near Bielsk Podlaski, (Podlaskie viovodeship). Main parameters were at average: pH 7,69; COD 1125 mgO2/dm3; BOD 143 mgO2/dm3; NH4+ 658 mgN/dm3; UV absorbance 0,326 and turbidity 59 NTU. An individual and integrated technique consisted of coagulation, Fenton’s reaction, ozonation and coagulation / ozonation was examined. The coagulation of leachate samples was accomplished by addition of Iron(III) sulfate. Maximum COD, color and UV absorbance removal rates at 44,8%, 75,5% and 67% were achieved by adding of 350 mgFe/dm3 of Iron(III) sulfate as Fe3+ respectively. The ozone dosages were used in the range of 50 to 750 mgO3/dm3 of the leachate. The maximum COD, color and UV absorbance removal was respectively 23,3%; 30,2% and 27,9% by applying a high ozone dose of 750 mgO3/dm3. After oxidation, the ratio of BOD /COD was increased from 0.11 up to 0.16. Fenton process reduced the COD, color and UV absorbance of the leachates by 64,9; 81,1and 68,7% respectively. Best operative conditions were obtained with Iron(III) sulfate dose 150 mgFe/dm3, and maximum hydrogen peroxide dose 2100 mgH2O2/dm3 (reaction time: 2h). Advantages associated with Fenton’s reagent include higher organic removal capacity, and bigger production of biodegradable byproducts, measured as BOD/COD ratio.
