  1. Using cd, cu, zn and cr as experimental toxicants and crucian as experimental creature, we employed the environmental biotechniques ( flame atomic absorption spectrophotometry, the method of improved pyrogallol autoxidation and electron microscopy ) to study the acute toxicity and secure concentrations of heavy metals to crucian ; the accumulation and distribution of mixed heavy metals to fingling crucian ; the activities of superoxide dismutase ( sod ) of gill and liver tissues and the hispathological and ultrastructural change of superfine structure of liver and kidney of crucian after cadmium exposure. through which, we intended to fully and systemically study the toxic influence of heavy metals to fish, and preliminarily discuss the influence of heavy metals pollution to the diversified level of fish such as individual, organ, tissue, cell and molecule. thus we tried to provide scientific evidence to establish preventative management measures, avoid and relieve the harm of heavy metals pollution to aquicolous ecosystem in time

  2. The effort of manganese removal was studied and the kinetics of manganese removal was tried to establish. the factors of dissolved oxygen concentration, fe2 + concentration, ph, p concentration and closing of the filter were studied to evaluate their effort for biological manganese removal, and the correlation of residual manganese and oxidation - reduction potential was also discussed. as the iron content of water was high, experiment results showed that the reaction was zero order, as the iron content of water was low, the reaction was first order. the time needed for the cultivation of biological manganese removal was 60 70 days. the filter operated at the filtration rate of 8 10m / h, silica sand of effective size 0. 95 1. 25mm filled the filter to a depth of 1200mm

    試驗結果表明，成熟后濾砂表面濾膜的x射線衍射圖譜與mno _ x ? 5h _ 2o （ x = 1 . 86 ）的x射線衍射圖譜一樣，濾膜成熟后的結構在進水物質不發生變化的情況下不發生變化;合適的碳磷比對生物除錳有明顯的促進作用，試驗條件下的投磷量不會對出水造成二次污染;生物除錳需要亞鐵的參與，亞鐵的存在除了能夠促進微生物分泌胞外酶並刺激其活性外，還通過鐵離子的變價傳遞電子，催化錳離子的氧化反應，從而促進對二價錳的降解。
