  1. The authour investigate the dosing conditions and effect of the pac to the huanghe water - source, which includes the following four parts : the selection of the pac ; the confirmation of dosing scheme and effect of the pac ; the research of application of potassium permanganate in combination with pac ; the research of the pac ' s modification and the modified effectiveness. the experiment is mainly carried out on the pilot system in the jieyuan water plan of tianjin. the results of the reseach include the following : l ) the pac from zunhua plant is selected as the better carbon for the source water of tianjin through the experiment ; 2 ) through the pilot experiment we conclude that the pac ' s best adding point is the mixing tank and the better dose is 10mg / l, on which the codmn of filtered water can be decreased to 40 % and the effluent have no problem of odour and color ; 3the adsorbing experiment show that pac mainly adsorb the organic matters which molecular wt., distribution between 500 and 3000, and can adsorb organic matters whose molecular wt., distribution are bigger than 6000 if the dose of it is adequent ; 4 ) pac together with potassium permanganate can remove the organic matter more effectively than each of them alone, and reduce the rising trend of turbidity of the flotation ' s effluent due to adding pac ; 5 ) the thesis made a research on the surface properties and the adsorbing capability of the modified carbon by oxidizer : the modified carbon with 20 % h2o2 can remove more organic pollutants than the untreated one by 12 % when we add a higher dose of coagulant ; 6 ) the modification of reduction and loading metal ions are also sttldied, and drow the following conclusions : the modified carbon with 5 % ammonia can enhance the organic matter ' s removal effectiveness by 10 % to the tianjin source water than the untreated one, and the modified one with loading metal ion remove the organic matters from the tianjin source water better ( 8 % ) than the untreated one due to the strong affinity betwween the humic acid and copper ion

    本文實驗主要是在天津芥園水廠中試系統上完成,論文成果和結論主要包括: 1 )通過靜態實驗選定河北遵化活性炭廠生產煤質炭為適合天津原水炭種; 2 )中試實驗確定粉末活性炭較佳投加點為混合池投加,較佳投加量為10mg l ,此時可使濾后水cod _ ( mn )降低40 ,且可較好地控濾后水嗅味和色度; 3 )初步確定粉末活性炭對原水中有機物吸附主要集中在分量在500 - 3000范圍內,投量增大時可吸附部分分量大於6000有機物4 )中試實驗表明:粉末活性炭與高錳酸鉀聯用可取得較兩者單獨應用時對有機物更好去除效果,且對因投加粉末活性炭而造成出水濁度升高有一定改善作用; 5 )研究並初步確定氧化改性對粉末活性炭表面性質和有機物去除效果影響:粉末活性炭氧化改性會使其表面酸性官能團大量增強,表面極性增加;經20過氧化氫改性活性炭在增大混凝劑投加量( fecl _ 3投量為15mg l )時對有機物總體去除效果較原活性炭提高12 , 1次氯酸鈉改性活性炭對有機物去除效果較原活性炭提高6 ; 6 )研究並初步確定還原改性、負載對原水中有機物去除效果影響:經5氨水改性活性炭可提高天津源水中有機物去除率達到10 ;負載銅離活性炭可提高對腐殖酸類物質去除能力,一般可提高8左右。
