  1. With the purpose of better understanding some weak links in this subject, we comprehensively and systematically compared the effects of some typical inhibitors and their different combined ways in inhibiting cd bioavailability in purple soil, further studied the laws and affecting factors of cd ' s transfer and transformation in soil - plant system, revealed the mechanisms inhibitors function, and explored the practicable inhibitor prescriptions and their usage. the results are expected to provide reliable techniques for controlling cd pollution of agricultural soils in chongqing and it is also significant to ameliorate soils polluted by other kinds of heavy metals. comprehensive methods including pot experiment, laboratory culture experiment, kinetic and thermodynamic adsorption - desorption experiment were adopted in this study, and the acidified purple soil was chosen to test, considering that cd is highly active in this soil

    本研究針對重慶市農業土壤的污染狀況,選鎘活性較高的酸化紫土為供試土壤,採用盆栽試驗、培養試驗、化學熱力學與動力學吸附試驗相結合的方法,系統研究和比較多種調控劑及其不同組合方式對鎘生物活性的效應,並揭示鎘在土壤?植物系統中的遷移轉化規律及影響因素,進一步分析調控劑的作用機理,探尋具實際應用價值的調控劑配方及合理使用的方法,這不僅可以為重慶市農業土壤鎘污染的防治供可靠的技術保障,而且對于其它重污染的治理也一定的理論意義。
  2. 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

    本文的實驗主要是在天津芥園水廠的中試系統上完成的,論文的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的煤質炭為適合天津原水的炭種; 2 )中試實驗確定粉末活性炭的較佳投加點為混合池投加,較佳投加量為10mg l ,此時可使濾后水的cod _ ( mn )降低40 ,且可較好地控制濾后水的嗅味和度; 3 )初步確定粉末活性炭對原水中機物的吸附主要集中在分子量在500 - 3000范圍內,投量增大時可吸附部分分子量大於6000的機物4 )中試實驗表明:粉末活性炭與高錳酸鉀聯用可得較兩者單獨應用時對機物更好的去除效果,且對因投加粉末活性炭而造成的氣浮出水濁度升高一定的改善作用; 5 )研究並初步確定氧化改性對粉末活性炭表面性質和機物的去除效果的影響:粉末活性炭的氧化改性會使其表面的酸性官能團大量增強,表面極性增加;經20的過氧化氫改性的活性炭在增大混凝劑投加量( fecl _ 3投量為15mg l )時對機物的總體去除效果較原活性炭高12 , 1次氯酸鈉改性活性炭對機物的去除效果較原活性炭高6 ; 6 )研究並初步確定還原改性、負載離子對原水中機物的去除效果的影響:經5氨水改性的活性炭可高天津源水中機物的去除率達到10 ;負載銅離子后的活性炭可高對腐殖酸類物質的去除能力,一般可高8左右。
