    固體之去除包括微顆粒及膠體物,無法以重沉澱之物質,可採用離心分離機、空氣除法、矽藻土過濾法、混凝沉澱快濾池等去除之。而溶解性固體去除則採用離子交換法、微細孔濾膜過濾、活性碳吸以及化學氧化等去除之。
  2. The mld of the ocean near the equator from 10 ? s to 10 ? n are less than 50 m and have no evident seasonal variability

    而在10 s 10 n之間的赤道近海域,因風應和凈熱通量的季節變化不大,且該區降水量較大,通量增, mld較淺,低於50米,且沒有明顯的季節變化。
  3. The calculated drafts covers the whole possible ship draft in the large amplitude motion ; secondly, the research creates and solves the ship large amplitude motion equations. on the one hand, the actual calculation takes into account the coupling between the different motion modes, on the other hand, in the process of calculation of the ship hydrodynamic coefficient, it considers the influence of the nonlinear factor. the hydrodynamic coefficient used in the calculation of froude - krylov force, diffraction force and radiation force changes instantaneously following the draft, and the hydrostatic buoyancy is computed very accurately for the instantaneous immerse hull

    本文的研究分為二個部分:首先利用frank源匯法計算水動系數,計算包括不同吃水時的質量和阻尼系數,吃水范圍涵蓋了船舶大幅度運動時所有可能的吃水;然後建立和求解船舶大幅度運動方程,在實際計算時一方面考慮了運動模態之間的耦合,另一方面在計算水動時,考慮了非線性因素的影響。 froude - krylov、輻射、繞射中的水動系數隨吃水瞬時變化,靜的計算精確到船體瞬時濕表面積,最後用四階龍格?庫塔方法在時域內求解船舶運動方程,並進行了載荷計算。
  4. 3. it studied the radiation problem of tlp, and paid attention to the computation of added mass and added damping about tlp which cylinders are set as regular polygon

    3 .研究了張腿平臺的輻射問題,重點研究了筒柱正多邊形分佈情況下,總體輻射質量和阻尼系數計算問題。
  5. 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點為混合池投,較佳投量為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色度; 3 )初步確定粉末活性炭對原水中有機物的吸主要集中在分子量在500 - 3000范圍內,投量增大時可吸部分分子量大於6000的有機物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的去除效果,且對因投粉末活性炭而造成的氣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;經20的過氧化氫改性的活性炭在增大混凝劑投量( fecl _ 3投量為15mg l )時對有機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機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、負載金屬離子對原水中有機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機物的去除率達到10 ;負載銅離子后的活性炭可提高對腐殖酸類物質的去除能,一般可提高8左右。
