Abstract
One of the develop leachate treatment methods is their anodic electrooxidation. As a result of the process there are many chlorinated compounds, but also those that chlorine in the molecule do not. In the first step chlorine is substituted in the molecule, and may be followed by separation of chlorine and the breaking of bonds resulting in the formation simpler compounds. Compound, which was determined in the raw leachate was the greatest concentration of dibutyl phthalate – 348 µg/l. At lower concentrations were detected: toluene – 285 µg/l, trimethylbenzene – 97 µg/l, acid, 3metylo- butyric acid – 82 µg/l, naphthalene – 65 µg/l, 1metylo- 3etylobenzene – 30 µg/l. During electrolysis determined new compounds, identified in the raw leachate. A very large group of halogenated compounds formed. For compounds whose concentration grew during the electrolysis until 60 min. were: 3chloro- 2-methyl- butane, acetonitrile, chloroform, 1,1dimetylo- 3chloro- propanol, 2chloro- 3etylobenzene. The group of compounds, where the concentrations of 10, 15 minutes of electrolysis to grow and after 30, 45 minutes is decreased until the end of the process (60 min). were among other compounds: 1,2,3trichloropropanol, 1chloro- 3metylobenzene, 3chloro- methane. Group of compounds, which were determined after 15, 30 minutes. electrolysis, but have not been determined after 60 min. i.e. at the end of the process, include: chloroacetone, benzoaldehyd, chlorinated nitrile, 1,1-dichloro-2-propanone.
