Objective to study the function of electromagnetic fields on decrease turbidity value and fluoride in drinking water 摘要目的探討復(fù)合電磁場(chǎng)降低水的渾濁度和除氟功能。
Results the turbidity value and fluoride in water were reduced 98 % and 80 % ~ 85 % after treated by electromagnetic fields 結(jié)果復(fù)合電磁場(chǎng)對(duì)水樣的渾濁度去除率達(dá)98 %以上,對(duì)氟化物去除率達(dá)到80 % ~ 85 % 。
The main characteristics of maltodextrin include stability , hygroscopicity , viscosity , turbidity and gelation behaviour as well 摘要麥芽糊精的主要性質(zhì)包括麥芽糊精的穩(wěn)定性、吸濕性、黏度、渾濁度和凝膠特性等。
Methods water sample was treated by electromagnetic fields , and the turbidity value and fluoride in water sample before and after treatment were detected 方法利用復(fù)合電磁場(chǎng)對(duì)實(shí)驗(yàn)室模擬水樣和現(xiàn)場(chǎng)水樣進(jìn)行處理,檢測(cè)處理前后水中的渾濁度、氟化物濃度,并計(jì)算去除率。
The present character of the deep bay mudflat has been created over centuries by the pattern of water flow around the bay , and the level of silt in the water which deposits on the mudflat 后海灣的渾濁度和水文均是該地的重要特徵,亦同樣具國(guó)際價(jià)值。灣內(nèi)沉積物堆積和侵蝕的模式形成如今的泥灘。
The suddenly intensified biological activities , led by the mixing of high mud - content freshwater and salty water and the rapid sedimentation of course , are believed to be responsible for the phenomenon . ulterior researches are needed for verifying and detailing the mechanism 主要原因是,高渾濁度的長(zhǎng)江淡水輸入,淡鹽水混合和泥沙迅速沉降導(dǎo)致生物活動(dòng)迅速加強(qiáng)的結(jié)果,其詳細(xì)機(jī)制還有待進(jìn)一步研究。
For a given ph condition , adsorption of trace metals on to sediments in the changjiang estuary can be described by the langmuir equation , and implies that increase in trace metal concentrations at natural waters has limited effect on trace metal partitioning coefficients because of high turbidity . 5 在某一給定ph條件下,長(zhǎng)江口懸浮泥沙對(duì)5種金屬的吸附符合朗格謬爾關(guān)系,這表明,在高渾濁度天然水體中微量金屬濃度的變化對(duì)它們?cè)诠?液兩相之間的分配系數(shù)影響不大。
From the research results , we can see that the initial reason , which leads to the degradation of xuanwu lake ecosystem , is pollution . pollution makes the water and sediments hypertrphiation , increases the opacity of water , and decreases the oxygen in water , so the wetland higher plant communities decrease or disappear . the wetland ecosystem loses the balance , while the biodiversity also decreases 研究結(jié)果表明,引起玄武湖濕地生態(tài)系統(tǒng)功能退化的初始原因是嚴(yán)重的環(huán)境污染問(wèn)題,污染加劇了水體及沉積物中的營(yíng)養(yǎng)鹽含量,增加了水體的渾濁度,降低了水體中的氧含量,從而導(dǎo)致濕地高等植物群落減少乃至消失,盡而引起濕地生物多樣性下降、生態(tài)系統(tǒng)失去平衡。
