反污染

In a word, anti-pollution needs your efforts!

在词， 反空气污染的需要您的努力！

"Overpopulation is the driving force behind virtually all environmental problems — air pollution, water pollution, the extinction crisis, global warming , yet it is rarely ever addressed by conservation groups," he said."They are really afraid of touching the issue and appearing antihuman."

"人口过多几乎是一切环境问题背后的动因，像大气污染、水体污染、生物灭绝、全球变暖，但是保守性质的组织基本没有提起过这个问题，"他说，"他们的确害怕摸了老虎屁股而显得'反人类'。"

In which the microorganism fouling was the main reason why the RO system operated and run diffidently, such as a great deal of sticky biofilm were attached to the surface of RO membrane, and which led to a higher influent press, a lot of energy consumption and lower water production and so on.

分析认为，RO膜污染主要来自无机物、胶体、有机物和微生物污染，其中微生物污染是造成反渗透水处理运行困难的重要原因，它会造成反渗透膜表面出现大量粘泥状生物膜，使进水水压过高，增大能耗，或造成膜的产水量下降。

The N9-CD is designed to prevent high hazard backsiphonage backflow and low-head backpressure (10ft. or less) from contaminating the potable water supply. The N9-CD is ideally suited to prevent backflow associated with hose connections and may be screwed directly to the sill cock, yard hydrant or wall hydrant.

N9-CD适用于防止高危害反虹吸回流和低压头反压力（3米以下）回流污染饮用水供应系统。N9-CD特别适合于防止软管连接有关的回流，可以直接螺旋连接到洒水龙头、庭院消防栓或墙式消防栓上。

A hose connection type anti-siphon vacuum breaker shall be installed where indicated on the plans to prevent the back siphonage of contaminated water.

软管连接类型的反虹吸真空断路阀应该安装在计划标注的防止污染水反虹吸的地方。

The 〓～t curve of UF with periodic back flush can be divided into two sections: the initial section represents the accumulation stage of undetachable cake layer, and the final section represents the equilibrium stage of accumulation and detachment of cake layer.

对周期反冲洗膜污染过程分析结果表明，周期反冲洗超滤〓～t曲线可分为两段：起初的直线增长段为不可逆滤饼层的累积阶段，直线的斜率为各次反冲洗不可逆膜阻增量△R；后期的水平段为滤饼层累积与剥离达到平衡的阶段。

objiective:to investigate the causes of the contamination of dialysis fluid.methods the level and species of bacteria were detected.results:the pathopoiesis bacteria and pathopoiesis bacteria in condition were identified in dialysis fluid,fluid b.offlake of soft water and preparing container.conclusions the contamination of'dialysis fluid is related with the untimely change of the filter in soft water machine and membrane of reverse osmosis,the contamination of fluid b.

目的：调查透析液和透析用水细菌污染的原因。方法：按《医院感染管理规范》的要求检测并鉴定致病菌。结果：透析液和透析用水、b液、软水口、配液容器培养出致病菌和条件致病茵。结论：血液透析液和透析用水细菌污染与软水机过滤器和反渗膜使用时间过长引起破损，未能及时更换，以及b液配制过程中细菌污染有关。

To reduce the poisonous compounds in the breeding ponds,five species of bacteria including denitrobacteria ,photosynthetic bacteria,thiobacteria and bioflocculation bacteria were screened from the breeding water.

针对养殖水体中因氨态氮、硫化氢和小分子有机酸富营养化引起的污染问题，分离筛选出硝化细菌、反硝化细菌、光合细菌、硫化细菌和生物絮凝菌等具有不同生理功能的污染物治理菌株，经优化配伍制备出性能优良的复合功能菌，结果表明：硝化细菌对氨态氮的去除率达97.8%，亚硝态氮的去除率达95.7%，反硝化细菌对硝态氮的去除率为96.4%，光合细菌和硫化细菌对硫化氢的去除率为55%，微生物絮凝菌的絮凝效率为83%；复合功能菌对CODCr、NH4+-N，总氮、硫化物的去除率分别可达94.3%，89.6%，88.7%和71.3%。

But to researchers like Ramanathan, these are the Olympics of atmospheric science — scientists can see firsthand the regional effects of the most furious anti-pollution effort of all time.

但对于研究人员，像Ramanathan这样的奥林匹克大气科学家而言，可以实时的在第一时间看到反污染努力对于区域的影响。

The results show that, the nitrate-N concentration in groundwater in the reed area was 0.2~0.8mg/L and significantly lower than that in surrounding wells (more than 20mg/L), and the reed wetland can remove nitrate pollution in shallow groundwater. The distribution of denitrifying bacteria showed obvious rhizosphere effect, and the higher biodenitrification in natural reed wetland was related to the distribution of denitrifying bacteria. There was a negative relationship between the nitrate-N concentration and the number of denitrifying bacteria in groundwater.

结果表明：芦苇区浅层地下水中硝酸盐氮仅为0.2~0.8mg/L，远低于湿地周围井水中硝酸盐氮质量浓度（大于20mg/L），芦苇湿地能够去除浅层地下水中硝酸盐污染；反硝化细菌在土壤中的分布呈现明显的根际效应；野生芦苇湿地较强的生物脱氮作用与反硝化细菌分布有关，地下水中硝酸盐氮含量与反硝化细菌分布呈负相关。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
