在水中的

It is concluded by the research that: it is viable to achieve the proposed treatmentobjectives to the alga concentrated feeding water during the peaking summer season,such as, lower turbidity, control of residual aluminum and pH, equivalent performanceof pre-chlorination, only if dosing chlorine dioxide as pre-oxidation algaecide,ploy-aluminum as coagulant, HCA as flocculant, without the needs of modification toexisting water treatment facilities.

研究结果表明：在不改变现有给水处理设施的情况下，以二氧化氯作预氧化除藻剂，聚合氯化铝作混凝剂，高分子HCA作助凝剂，既可以有效降低水的浊度、控制水中余铝，又可以合理调节水的pH值，同时水中余氯还可以达到滤前加氯的效果，是处理夏季高藻期原水比较理想的工艺路线。

However, the surplus residual chlorine can affect people's taste and smell, destroy the quality of water. Moreover, in the process of disinfection, chlorine can react with organic matter and produce a series of hydrochloric ether such as chloroform, bromoform, bromodichloromethane, chlorodibromomethane and so on, these matters can cause to some extent cancer to human body.

但是，水中过量的余氯会影响水的口感和气味，破坏水的品质；此外，在消毒过程中，氯与水中残余的有机物产生化学作用，生成一系列氯代烃如三氯甲烷、溴仿、溴二氯甲烷、氯二溴甲烷等，这些物质会对人体产生一定程度的致癌作用；对于以自然水源作为生活用水来源的城市必然要对水加氯消毒后才可使用。

The analytical principle of the instrumental method is primarily changing organic chloride into inorganic chloride by complete combustion, then inorganic chloride is absorbed and analyzed with microcoulomb titration method, and from this analyzing result, we can calculate out different mode of organic chloride.

研究发现，CEH三段漂白废水中AOX大部分是出现在C段和E段，非木材浆C段漂白时约有2.5-4kg／odt的AOX形成，其中C段废水中溶出的AOX一般在2kg／t浆左右，E段为1-2kg／odt；H段废水中AOX含量较少，一般少于1kg／odt；非木材纸浆CEH漂白产生的AOX低于木材纸浆。

In accordance with the method of silver nitrate titration of chloride in water,the sources of the uncertainty of measurement of chloride in water were analyzed and the uncertainty was evaluated.

根据硝酸银滴定法测定水中氯化物的含量，分析了该方法测量不确定度的来源，评定了水中氯化物的测量不确定度，在各不确定度中，以标准溶液配制与样品分析时滴定消耗的硝酸银体积引入的不确定度较大。

Of water by the addition of sulfuric acid,was poured into 2 liters of water at 60℃.

将10克5-硝基喹啉溶解在50ml加有硫酸的水中，接着将配好的溶液倒入2升60℃的水中。

Moreover, large amount cladocera can immediately decrease algae concentration.

此外，当水中施放较多数量的枝角类时，则能在短时间内减少水中小球藻的数量。

The nitrogen and phosphorus in the sediments and interstitial water within 5cm depth gradually decreased along with the root system absorption, and nitrogen and phosphorus release were apparent depressed with the Limnanthemun nymphoides growth.

通过植物根系对沉积物和间隙水中营养盐的直接吸收，使表层(0~5cm)沉积物与间隙水中氮磷营养盐的水平在实验结束后有明显下降，对于控制沉积物内源营养盐释放有重要的作用。

The biomass photosynthesis activity of Ruppia maritima and Potamogeton pectinatus and the proline,malondialdehyde,catalase,and chlorophyll contents in their leaf-tissues in response to salinity were studied by investigating the plants cultured with reclaimed wastewater of different salinities.

通过在不同盐度再生水中培养川蔓藻和蓖齿眼子菜，研究了它们的生物量、光合强度及其组织中的脯氨酸、丙二醛、过氧化氢酶和叶绿素的含量变化对再生水中盐度的响应。

Xinhua net Shenyang on November 30 report 100 thousand tons sewage treatment plant is in capability of processing of a day the Liaoning of duck green Jiang Bian saves red east city building, on November 30, sewage treatment plant undertook water experiments successfully connecting.

新华网沈阳11月30日电一座日处理能力10万吨的污水处理(通过物化方法去除水中一些物质的过程)厂在鸭绿江边的辽宁省丹东市建成，11月30日，污水处理(通过物化方法去除水中一些物质的过程)厂成功进行了通水试验。

This picture was taken at 4:50PM and there were very few snorkelers there, which prompted me to go back to the condo to get my swimming trunks because I could not wait any longer to jump into the water Look carefully and you can see two poeple in the water.

此照片摄於下午4：50，只有小许的浮潜客在那儿，促使我赶快回到公寓，拿起泳裤，因为我简直等不及想马上跳入水中仔细看能看到水中有两个人，浮潜是多麼的有趣。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
