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 。When as or pac was used as a coagulant, coagulation removal of turbidity was enhanced at low ddmbac concentration ( 10mg / l ), but hindered at high ddmbac concentration ( 350mg / l ). however, its effect on pac was slightly smaller than that on as. ddmbac impacted the coagulation primarily through enhancement for charge neutralization and bridging of
低濃度的ddmbac （ 10mg / l ）可適當增強硫酸鋁和聚合氯化鋁的混凝效果，高濃度的ddmbac （ 350mg / l ）則顯著干擾混凝，但ddmbac對聚合氯化鋁混凝效果的促進作用不如對硫酸鋁明顯。These results show that the function of coelomic fluid is not to oxidize sulfide but to store it. in a word, the u. unicinctus can tolerate high sulfide concentrations and low oxygen concentrations, and its tolerating mechanism is complex and versatile
