The results showed COD removal rate was no less than 50%, turbidity removal rate more than 90%, while using sodium acrylate-acryamide copolymer as flocculant and CaC2 as aid-flocculant. The flocculate is nonpoisonous and can be recycled.

结果表明，采用丙烯酸钠-丙烯酰胺共聚物作絮凝剂，氯化钙作助凝剂处理淀粉废水时，COD_去除率可达50％以上，浊度去除率可达90％以上，所得到的絮体无毒，可进一步回收利用。

You will come in May between June, between choice section shorter give birth to half lignification branch in those days, from base the ministry cuts dirty to insert spic, topmost reservation comes 3 pieces 5 flocculus, if branch is too long, yi Ke bite off carries a tip on the head, cuttage medium can use humus soil of orchid mud, high mountain, vermiculite, pearlite or Huang Xin earth to wait, thick about 15 centimeters reach 20 centimeters, the catchment layer that lower berth reachs 8 centimeters 7 centimeters; medium after in season is wet, in will inserting spic to insert matrix, deepness of the be buried that insert spic makes an appointment with the 1/2 that grows for spic, a few cuttage also can choose the family full-dress medium generation makes big flowerpot cuttage seedbed.

你可于5月至6月间，选择节间较短的当年生半木质化枝条，自基部切下作插穗，顶端保留3片至5片小叶，若枝条过长，亦可截去顶梢，扦插介质可用兰花泥。高山腐殖土。蛭石。珍珠岩或黄心土等，厚约15厘米至20厘米，下铺7厘米至8厘米的排水层；把介质喷湿后，将插穗插入基质中，插穗入土深度约为穗长的1/2，家庭少量扦插也可选用大花盆盛装介质代作扦插苗床。插后加盖塑料薄膜保湿，温度控制在25℃至30℃之间，加设荫棚遮挡阳光，或挪放于树荫下，始终保持扦插基质湿润，东鹃约过1个月即可生根，而西鹃则要60天至70天才能生根。9月后可减少遮荫时间，并追施稀薄尿素液一次，浓度约为0.2%，10月下旬即可上盆。

This paper has simply summarized on the application and research of the internal processing of fluoric wastewater in recent years, and shows the development of the research on the processing of fluoric wastewater .

本文就近年来国内对含氟废水处理研究及应用概况作了简要综述，可看出含氟废水处理的研究有了较大进展。本文对近几年来国内外对含氟废水的研究进展情况作了简单述评。

Reaction conditions are studied, and the result shows that it is better to adopt mercuric oxide or mercuric fluoride as fluorination catalyst with reaction temperature -20~-10℃.

结果表明，采用氧化汞或氟化汞作氟化催化剂、氟化氢作溶剂较好，适宜的反应温度为－20~-10℃，较长的反应时间(48 h)和增加氟化氢和催化剂的量有利于氟化。2-氯－5-三氯甲基吡啶的转化率和选择率均可达到97%以上。

You will live in the land I gave your forefathers; you will be my people, and I will be your God.

Its working principles for the saws mounted on a frame on the saw blade, driven by the connecting rod with the saw frame for resumption of exercise often, at the same time through the movements transmission Continuous feed down for sport in order to achieve the sawing of stone processing.

其工作原理为装在锯框上的锯条在连杆的带动下随着锯框作往往复运动，同时通过升降传动机构连续向下作进给运动，从而实现对石材的锯切加工。

They fell in tranquil while all creatures in their sweet dreams. Then we made a snowman, fraze his free-running legs, and we enjoy our success.

于是，我们做了雪人，将那自由的腿儿凝固住，伫望着阳光下的它，心里满是成功的喜悦；未久，汗流满面的雪人儿终于化为水，变作水汽，飞回空中，还作自由的精灵。
