例句与用法

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
试验结果表明,成熟后滤砂表面滤膜的x射线衍射图谱与mno _ x ? 5h _ 2o ( x = 1 . 86 )的x射线衍射图谱一样,滤膜成熟后的结构在进水物质不发生变化的情况下不发生变化;合适的碳磷比对生物除锰有明显的促进作用,试验条件下的投磷量不会对出水造成二次污染;生物除锰需要亚铁的参与,亚铁的存在除了能够促进微生物分泌胞外酶并刺激其活性外,还通过铁离子的变价传递电子,催化锰离子的氧化反应,从而促进对二价锰的降解。
The fluorescence intensity of the phosph atase increased , followed by a decreasing process , in the temperature region of 40 - 90 c . the enzyme was inhibited by naf significantly and the fluorescence spectra of the protein were influenced obviously by the concentration of naf . the data from our experiments showed that the bivalent cations can modulate the activity of the phosphatase but maybe is independent of the tertiary structure
Edta对此种磷酸酣酶也有抑制作用，因此用7种二价阳离子处理磷酸酷酶，发现不同金属二价阳离子对这种磷酸酷酶活性和荧光发射光谱的影响不同，因此二价阳离子调控此酶活性，但可能与荧光光谱所反映的三级结构变化无关。
Deferrizers and demaganizers are series of products designed by our company for underground water with comparatively high iron and managanese content according to aerating oxidation priciple . in these prducts , packed natural manganese sand in filter is applied as filtering materials , and oxygen in air is applied as oxidants , to make ferrous iron in water oxidized into ferric iron , in a same time , oxidation reaction makes its produced its produced substances left in filtering materials for purposes of deferrization and deman - ganization
除铁锰装置是我公司针对铁、锰较高的地下水，按曝气氧化法的原理而设计的系列产品，它是利用过滤器内装填城然锰砂为滤料，利用空气中的氧化剂，使水中的二价铁，同时发生氧化反应使其物进截留在滤料中，从而达到除，除锰的目的。
As a new separation membrane technology developed in recent years , nanofiltration ( nf ) membrane is the most appealing field of membrane science and technology compared with those traditional membranes , the advantages of nf membranes are as follows : having hole diameters of nanometers , low operation pressure , economic for it can replace many procedures in traditional process and separation technology , having high selectivity to different irons , and so on
纳滤膜是近十几年发展起来的一种新型的压力驱动膜，它所具有的特殊的纳米级孔径使其具有很多分离膜不具备的优点，如操作压力低、对二价和高价离子具有高的选择性、具有较好的压密性和较强的抗污染能力等。
