摘要
针对滦河源水水质，在常规处理的基础上分别进行了生物活性炭和臭氧生物活性炭两种深度处理工艺的对比试验。结果表明，普通生物活性炭和臭氧生物活性炭两种深度处理工艺均能有效改善常规工艺的出水水质，经过色质联机检验，水中各类微量有机物的种类和含量均有了显著降低。相比较而言，臭氧生物活性炭对有机物具有更高的去除率，对氨氮的平均去除率为58．3％，对CODMn的平均去除率为58％，对UV254的平均去除率为62．3％，对TOC的平均去除率为51．6％，对分子质量为1～5ku有机物的去除率〉60％，对分子质量〈1ku和分子质量〉5ku的有机物去除率〉30％。
Pilot plant researches of two advanced drinking water treatments schemes including biological activated carbon （BAC） and ozone/biological activated carbon（ O3/BAC ） were conducted for polluted source water of Luanhe River. The analysis data of gas chromatography and mass spectrum（ GCMS） show that the organic substances sorts and content are greatly decreased, which proves that BAC and O3/BAC can effectively improve treated water quality of conventional process. Comparatively, O3/BAC has higher efficiency of organic substances removal. During the test period, mean removal rates of 58.3%, 58%, 62.3% and 51.6% have been obtained for NH3 - N, CODMn, UV254 and TOC in O3/BAC treatment. Especially, O3/BAC process can obtain for NH3 -N, CODMn, UV254 and TOC in O3/BAC treatment. Especially, O3/BAC process can obtain mean removal rates of above 60 % for the organic substances with molecular weight of 1 -5 ku, and 30% for the organic substances with molecular weight of 〈1 kuand 〉5 ku.
