  1. The experimental results showed that in the condition of this experiment four algaecides all had strong removing rate on algae, and their removing rate increased with dose increasing, and decreased with algae density increasing. according to the removing rate on algae and cost value or so, the sequence of four algaecides from good to bad were potassium permanganate, copper sulfate, hydrogen peroxide and sodium hypochlorite. in the condition of this experiment, the suitable dose of potassium permanganate was 0. 8mg / l, the algal removing rate was beyond 90 % and the cost of this algaecide was only 0. 0068 / m3. the efficiency of algae removal by four algaecides for huanghe river water was studied. the results showed that the majority of huanghe river water was bacillaroiphyta, and the dominant genera was melosira, which reached 78 % ~ 94 %

    結果表明,在實驗條件下,四種殺藻劑均具有一定的殺藻效果,藻類去除率均隨藥劑投量的增加而提高;原水藻類數量影響殺藻劑殺藻效果,四種殺藻劑的藻類去除率均隨原水藻類數量的增加而降低;通過殺藻效果、經濟性以及安全性等方面的綜合比較,對于以有毒藍藻為優勢藻屬的引灤水,四種殺藻劑的優劣程度從優到劣排序為:高錳酸鉀硫酸銅過氧化氫次氯酸鈉;在實驗條件下,高錳酸鉀適宜投加量為0 . 8mg l ,藻類去除率高於90 ,所需的藥劑費用僅為0 . 0068元m ~ 3 。
  2. The best efficiency of algae removal is 99 %, and this technique can reduce the dose of coagulation agent. at last, this study analyzes the efficiency of all kinds of algae removal in the every phase of coagulation - filtration processing

    將混凝工藝與過濾工藝相結合,研究其組合對藻類的去除效果,將二者恰當組合的最好去除率可達99 。
  3. At the same time, we further study the affection of the coagulant aids active silica acid and oxidizing agent hydrogen peroxide upon the efficiency of coagulation. results show that the suitable preoxidation and adding coagulant aids can enhance the coagulation effect. the best dose are : [ fe3 + + al3 + ] / [ sio2 ] = l / 2 for active silica acid and 4mg / l for the oxidizing agent,

    同時,對助凝劑活化硅酸和氧化劑雙氧水對混凝效果的影響作了進一步的研究,發現經適當預氧化和添加助凝劑可強化混凝效果,適宜劑量分別為:活化硅酸的最佳添加比例為[ fe ~ ( 3 + ) + al ~ ( 3 + ) ] [ sio _ 2 ] = 1 2 ,氧化劑雙氧水最佳劑量為4mg l 。
  4. When the water dose was 20 % and engine speed was 2000r / min, the maximum fuel saving was 4. 1 % ; the thermal efficiency of emulsified fuels was higher than that of using pure diesel oil. nox and particulates emissions were reduced greatly by using emulsified fuels. when water dose was 20 % and engine speed was 1500 r / min, the maximum nox reduction was 43. 4 % ; the average of particulates under all loads was reduced by the extent of 46 % ~ 64 %

    結果表明:燃用乳化油節油率有所提高,當n = 2000r min ,摻水率為20時最大節油率可達4 . 1 ;燃用乳化油的熱效率也高於燃用純柴油; no _ x 、顆粒排放比燃用純柴油時則有大幅度降低,當n = 1500r min摻水率為20時, no _ x排放量下降的最大值可達43 . 4 ;固體顆粒物排放量在整個負荷范圍內的平均值比燃用純柴油時低46 64 ;隨著乳化油摻水量的提高,排放效果改善越明顯;而thc和co的排放量則比燃用純柴油時有所升高。
