  1. The article based on the rural development program - chenjiao cow breeding program in huang yuan county, qinhai province. through collecting second - hand information. using tools of pra, such as questionnaires, key informant interview, matrix ranking. organizational chart, individual interview to investigate the program ' s construction, beneficial result, and problems. after that using problem analysis tree to analyze the information and find that : the up - down extension systems through beneficial inducement did not change farmers " ideas, the fanners have owned the program funds but did not breed cow. the extension systems of our country is not perfect, short of funds, no advanced equipment, dual leadership, multiple function lead to inefficient extension work. the separation of teaching, research and extension lead to unskilled extension workers. the farmers lack of skills. consultation and funds. the above deficiencies caused the inefficient extension work

    本文通過對湟源縣城郊鄉納隆口村的「 2002年農業綜合開發多種經營城郊養牛項目」項目的跟蹤調查,通過二手資料的收集,應用問卷調查法、知情人(村長)訪談法、矩陣排列、構關系圖、個體訪談等pra的方法了解項目的建設情況、項目實施后的效益及存在的問題,再應用參與式的方法進行綜合析,發現:從上到下的推廣體系通過利益誘導並沒有使農民的行為發改變,出現了項目戶擁有項目款而不養牲畜的情況;推廣體不順,經費短缺、設備落後、雙重領導、職能繁多導致推廣工作乏力;教科推脫使農學院未發揮作用導致推廣人員素質低、農戶缺乏技術、咨詢、資金。
  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 ,且可較好地控濾后水的嗅味和色度; 3 )初步確定粉末活性炭對原水中有物的吸附主要集中在子量在500 - 3000范圍內,投量增大時可吸附部子量大於6000的有物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有一定的改善作用; 5 )研究並初步確定氧化改性對粉末活性炭表面性質和有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 )時對有物的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物的去除效果較原活性炭提高6 ; 6 )研究並初步確定還原改性、負載金屬子對原水中有物的去除效果的影響:經5氨水改性的活性炭可提高天津源水中有物的去除率達到10 ;負載銅子后的活性炭可提高對腐酸類物質的去除能力,一般可提高8左右。
