Abstract The article presents research results of the introduction of powdery activated carbon to the existing technological system of the groundwater treatment stations in a laboratory, pilot plant and technical scale. The aim of the research was to reduce the content of organic compounds found in the treated water, which create toxic organic chlorine compounds (THM) after disinfection with chlorine. Nine types of powdery active carbons were tested in laboratory scale. The top two were selected for further study. Pilot plant scale research was carried out for the filter model using CWZ-30 and Norit Sa Super carbon. Reduction of the organic matter in relation to the existing content in the treated water reached about 30%. Research in technical scale using CWZ-30 carbon showed a lesser efficiency with respect to laboratory and pilot-plant scale studies. The organic matter decreased by 15%. Since filtration is the last process before the individual disinfection, an alternative solution is proposed, i.e. the second stage of filtration with a granular activated carbon bed, operating in combined sorption and biodegradation processes. The results of tests carried out in pilot scale were fully satisfactory with the effectiveness of 70–100%.

使用活性炭去除地下水中的有机物

摘要 本文介绍了在实验室、中试和技术规模的地下水处理站现有技术系统中引入粉状活性炭的研究成果。研究的目的是减少处理过的水中发现的有机化合物的含量，这些有机化合物在用氯消毒后会产生有毒的有机氯化合物 (THM)。在实验室规模中测试了九种类型的粉状活性炭。选出前两名进行进一步研究。对使用 CWZ-30 和 Norit Sa Super 碳的过滤器模型进行了中试规模的研究。与处理过的水中的现有含量相比，有机物的减少量达到了约 30%。使用 CWZ-30 碳的技术规模研究表明，与实验室和中试规模研究相比，效率较低。有机物减少了15%。由于过滤是单独消毒之前的最后一个过程，因此提出了一种替代解决方案，即使用颗粒活性炭床进行过滤的第二阶段，结合吸附和生物降解过程进行操作。中试规模的测试结果完全令人满意，有效率为 70-100%。
