Fluoride is human life is one of the essential trace elements. Adequate fluorine can make strong bones and teeth, dental caries, rece morbidity. But long-term accumulation in the body fluorine can cause bone formation CaF2, crisp, osteoporosis, ligament calcification spots glaze teeth and stiff joints even paralysis, or lose labor ability. For many years, drink water from non-beryl problems with serious bothering people, from non-beryl water distribution is very extensive. Drinking HanFuLiang than 1.0 mg/L of water, with the increase of concentration in the incidence of dental fluorosis, increased, while more than 4.0 mg/L, may increase graally. According to the national health survey about 77m people drinking HanFuLiang than 1.0 mg/L of water, including nearly 500 million people in the water HanFuLiang than 5.0 mg/L. So the economic and effective, simple operation of fluoride method is very necessary.
This experiment using adsorption and ion exchange fluoride, choose the activated alumina as agent, except by single factor experiment investigation to the activated alumina concentration, raw water, fluorine and mixing time and PH of the activated alumina fluoride rate. This experiment is activated alumina fluoride in the best condition for every 100 ml fluorin ion concentration of 3mg/l fluorine-containing wastewater, ph value of water for about 7, join the activated alumina 2gb, stirring time for 30min. At best condition of experiment activated alumina fluoride reco-very was the highest rate.

下面是我论文的摘要 哪位达人能帮我翻译一下啊~~~ 有必要的话可以加分啊!!
氟是人体生命必不可少的微量元素之一。适量的氟能使骨骼、牙齿坚固,减少龋齿发病率。但是氟长期积累于人体时能深入骨骼生成CaF2,造成骨质松脆,牙齿斑釉,韧带钙化,关节僵硬甚至瘫痪,严重者丧失劳动能力。多年来,饮用高氟水所带来的病痛严重困扰着人们,高氟水分布十分广泛。长期饮用含氟量大于1.0mg/L的水时,随着水中氟离子浓度的增大,氟斑牙的发生率也升高,当大于4.0mg/L时,氟骨症逐渐增多。据卫生部调查全国约有7700万人饮用含氟量超过1.0mg/L的水,其中近500万人的饮水中含氟量超过5.0 mg/L。因此研究经济有效、操作简单的除氟方法非常必要。
本实验采用吸附与离子交换法除氟,选用活性氧化铝作为除氟剂,通过单因素实验考察活性氧化铝加入量、原水氟浓度、原水PH及搅拌时间与活性氧化铝除氟率的关系。本实验得出活性氧化铝除氟的最佳条件为每100ml氟离子浓度为3mg/l的含氟废水,原水ph值为7左右,加入活性氧化铝2g,搅拌时间为30min。此时最佳条件实验的活性氧化铝除氟率最高为98.8%。
问题补充:我想要真正的翻译啊。。。不是用google什么的翻译一下就算了的。。。翻译软件我也有的。希望英语达人们能帮帮忙啦~~
Fluoride is a trace element essential to human life as one. Appropriate amount of fluoride can bones, strong teeth and rece the incidence of dental caries. However, long-term accumulation of fluoride in human bone-depth generated when CaF2, causing bone Crisp, dental enamel plaque, calcified ligaments, stiff joints and even paralysis, severe loss of the ability to work. Over the years, the high fluoride drinking water brought about by serious illness to plague people, the distribution of a wide range of high fluoride water. Long-term consumption of fluoride is greater than 1.0mg / L of water, with the fluoride ion concentration of water increased the incidence of dental fluorosis increased rate, when more than 4.0mg / L, the increasing number of skeletal fluorosis . According to the National Ministry of Health survey of about 77 million people drink fluoride in excess of 1.0mg / L of water, of which nearly 500 million people of fluoride in drinking water of more than 5.0 mg / L. The study cost-effective, simple method of fluoride removal is necessary.
Experimental use of the adsorption and ion exchange fluoride removal, activated alumina selected as defluorination agent, through the activity of single factor experiment study the amount of alumina, the raw water fluoride concentration, the raw water and the stirring time PH activated alumina and fluoride removal rate. Activated alumina obtained in this experiment the best conditions for fluoride removal per 100ml fluoride ion concentration of 3mg / l of fluorine-containing waste water, raw water ph value of 7 or so, by adding activated alumina 2g, mixing time of 30min. At this time the best experimental conditions fluoride removal rate of activated alumina up to 98.8%.

The fluorine is one of the essential trace element of human body have.Just the right amount of of the fluorine can make skeleton, tooth hard, decrease Qu Chi the outbreak lead.But the fluorine long-term backlog is at the human body can go deep into the skeleton born CaF2, result in loose bone substance frailty, tooth spot enamel, ligaments calcify, the joint is stiff to even paralyze, the serious loses labor ability.Many in the last yearses drink the slight illness that Gao Fu Shui brings to seriously perplex people, high fluorine humidity the cloth is very extensive.Over a long period of time drink to contain fluorine Be had great capacity to a 1.0 mgs|L water, along with the aggrandizement of fluorine ion density in water, the incidence rate of fluorine spot tooth also goes up and be is bigger than a 4.0 mgs|L, the fluorine bone disease increases graally.Has around according to the health department survey whole country 7700 myriad peoples drink to contain amount of fluorine over the 1.0 mgs|L of water, contain amount of fluorine over the 5.0 mgs in the drinking of about 500 myriad peoples among them|L.Therefore the research economy is effective and operate simple of in addition to the fluorine contains very necessary method.
This experiment adoption adsorbs and ion exchange method in addition to fluorine, the choice activity oxidizes aluminum as in addition to fluorine, oxidizes aluminum to join quantity, the raw water fluorine density, raw water PH and agitation through a single factor experiment investigation activity for time to oxidize aluminum with activity in addition to fluorine rate of relation.This experiment the activity oxidizes aluminum in addition to the best condition of fluorine for each the 100 ml fluorine ion density for the 3 mgs|the containing of l fluorine waste water, the raw water ph is worth to 7 or so, join an activity to oxidize the aluminum 2 gs, mix blend time is 30 mins.The activity of the best condition experiment oxidizes aluminum at this time in addition to the fluorine leads tallest is 98.8%.
