| 1. | But with the advent of disinfected by products , the chlorine disinfection lowers the risk of water microorganism , yet raises the risk of water chemicals , which also has some impacts on the safety of potable water
但是氯消毒技术在降低了饮用水微生物风险的同时，由于消毒副产物的形成提高了饮用水的化学物风险，消毒剂本身对饮用水的安全性也有一定的影响。 |
| 2. | 4 . when the chloramines disinfection water is combined with the liquid chlorine disinfection water and reaches some stable ratio for a long time , the great reduction of the remained and total chlorines in the piped system will be obtained
4 、氯胺消毒处理后的水与液氯消毒后的水在管网中混合达到一定比例，长时间稳定接触，将会出现管网水余氯、总氯大幅度降低的现象。 |
| 3. | Over the past century , the chlorine disinfection of potable water has played a vital role in controlling the water - causing diseases and improving the safety of water microorganism , thus contributing largely to lowering the rate of the water - causing diseases
100余年来，饮用水氯消毒为人类控制水致疾病、提高供水微生物安全性起到了至关重要的作用，大大降低了水致疾病的发病率。 |
| 4. | ( 4 ) chloramines disinfection can effectively control the generations of microorganism and has more advantages over liquid chlorine disinfection in reducing the amount of aoc ( assimilability organic carbon ) in potable water improving its stability of microorganism
( 4 )氯胺消毒对生物膜成长具有极好的抑制作用，在减少饮用水的aoc含量、重庆大学硕士学位论文中文摘要提高饮用水的生物稳定性方面优于液氯消毒。 |
| 5. | ( 2 ) chloramines disinfection can lower disinfection byproducts greatly on the basis of guaranteeing the safety of microorganisms . ( 3 ) chloramines disinfection can do much better in improving potable water quality and reducing its bad effects than what liquid chlorine disinfection can do
( 2 )在保证饮用水微生物安全性的条件下，氯胺消毒相对于液氯消毒在降低三氯甲烷、二氯乙酸和三氯乙酸这三种消毒副产物方面有明显的作用。 |
| 6. | The drinking water headwaters sourc suffers organic pollution phenomenon gradually widespread with severity , but the running water factory still adopts a traditional craft to add the chlorine disinfection , making the organic matter in the city running water especially the chloroform content seriously exceeds the allowed figure
饮用水水源遭受有机污染现象日趋普遍和严重,而绝大部分自来水厂仍然采用传统工艺加氯消毒,使得城市自来水中有机物特别是三氯甲烷含量严重超标。 |
| 7. | 3 . by comparing the two different ways of disinfection , the study shows as the followings : ( 1 ) more effective and better disinfection results will be obtained by means of chloramines disinfection ( which is more suitable for medium - long distance piped system ) in the piped system than those by liquid chlorine disinfection
3 、通过对氯胺消毒与液氯消毒对比试验研究表明： ( 1 )氯胺消毒在管网中的持续消毒效果明显优于液氯消毒，更适用于中远距离输水管线。 |
| 8. | As a kind of long - time applied disinfection means , the technology of chloramines disinfection has gradually become one of the research subjects to replace the traditional liquid chlorine disinfection , with regards to its feature of lowering the organic halide in the piped water and maintaining original disinfection properties in the piped system
氯胺消毒工艺是一种使用时间较长的消毒方式，具有降低自来水中有机卤化物及长时间维持管网系统中剩余消毒剂的特性，已逐渐成为替代传统液氯消毒工艺的研究方向之一。 |
