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 。 -
Some main results of testing research were as fellows : i. in the course of testing of leaching zinc dross, leaching zinc dross by sulfuric acid was researched and the effects on the leaching rate of the zinc dross were analyzed by author, the optimum conditions of leaching testing of zinc dross were determined as fellows : liquid - solid ratio 6 : 1, stirring ratio 250r / min, granularity 120 mesh, the soaking time 5h, the concentration of sulfuric acid of 30 %, and under these conditions, the rate of leaching zinc is above 92. 0 %. ii. in the course of testing of purification, on the basis of comprehending and comparing all present methods of the manganese - removal and iron - removal, the oxidizing method of manganese - removal in zinc sulfate solution using ammonium persulfate was put forward and the oxidizing method of iron - removal in zinc sulfate solution using the goethite process and oxidation - hydrolysis process was adopted
