      　　石英砂過濾器是一种過濾器滤料选用石英砂作为填料。有利于去除水中的杂质。原水通过石英砂過濾器排出来的余氯、小分子有机物、胶体类物质假如不除掉会对反渗透膜造成风险，而活性炭過濾器的作用就是对这些物质具有强壮的吸附才能，为下级反渗透处理提供优质水源。

      　　活性炭顆粒的特性是有很多的毛細孔和含氧管能團，由于結構疏松、形狀沒有規則，具有了遠遠大于其他濾料的表面積，比表面積可達1000m2/g，也就提高了活性炭過濾器的吸附才能，有用的吸附了藻類及其他小分子顆粒，並降解了水中有COD。
      　　石英砂過濾器的性能特点：其还有过滤阻力小，比表面积大，耐酸碱性强，抗污染性好等优点，石英砂過濾器的共同优点还在于通过优化滤料和過濾器的设计，完成了過濾器的自适应运转，滤料对原水浓度、操作条件、预处置工艺等具有很强的自适应性，即在过滤时滤床自动形成上疏下密状态，有利于在各种运转条件下确保出水水质，反洗时滤料充分散开，清洗作用好。
      　　石英砂過濾器可有用去除水中的悬浮物，并对水中的胶体、铁、有机物、农药、锰、细菌、病毒等污染物有显着的去除作用。并具有过滤速度快、过滤精度高、截污容量大等优点。主要用于电力、电子、饮料、自来水、石油、化工、冶金、纺织、造纸、食物、游泳池、市政工程等各种工艺用水、生活用水、循环用水和废水的深度处置领域。

	ON THE PACIFIC OCEAN.  The story of the coolie-trade and some of the conversation that followed cleared the mystery that surrounded the narrator and had given him the name by which he was known. He had been an active participant in the peculiar commerce of the East, which includes the violation of laws whenever they prove inconvenient, such as the smuggling of opium and the shipment of coolies to the countries where they are in demand. His latest venture was one that required considerable secrecy, as it involved the purchase of arms for the rebels in Japan. For this reason he had been very cautious in his movements around Yokohama and during his whole stay in Japan, and he had found it judicious to leave the country on the vessel that came so near being wrecked in the typhoon that overtook our friends. He was safely away from Japan now, and the arms that he had purchased for the rebels were in the hands of the government. He had made money by the operation, and was on the lookout for something new. "It's a very simple matter," said Captain B——, "when you know about it. The fact is, that we were once very near losing our lives by Chinese pirates, and we don't propose to have another risk like it."

"Yes, I started with a shaking chill. I'm afraid, every minute, I'll go out of my head. Oh, Smith, Oliver's alive! He's alive, he's alive, and I've come to save his poor wife from a fate worse than death!"   "Let me look at you," she said, tenderly. "Let me get water and some towels."

We first drove through the suburb Montigny-sur-Sambre, which shared the fate of Jumet, and was entirely destroyed by fire. After leaving the town we went in the direction of Chatelet, where we found an immense battle-field. Terrific fighting must have taken place here, for the number of buried was enormous. On a wide stretch of land we saw a great number of mounds, with crosses, and covered with quicklime. On the crosses the numbers are given of the brave who fell there. So I read, for example:— distributed evenly. Sallie, as usual, goes to the Adirondacks.

“You tell me who knew the way to get into the captain’s safe and I’ll try to get the emeralds.”   "Well?" said the officer. Wild Shooting of the Boys Saves The Surprised Colored Man. 273

... rich in the metals that kept the Terran Confederation going—one vital link in a galaxy-wide civilization. But the men of Fruyling's World lived on borrowed time, knowing that slavery was outlawed throughout the Confederation—and that only the slave labor of the reptilian natives could produce the precious metals the Confederation needed!   Turner had not been above five minutes in releasing the monk; but, when he came to the entrance of the keep, Merritt and the remainder of the band were sharply engaged with the domestics and the few tenants who kept guard about the castle. The smith pushed on with the monk; passed Merritt and the others, who closed in his rear; and, with that boldness, which often effects what more prudent courage would fail to accomplish, rushed into the midst of the assailants, brandishing his weapons, and shouting defiance at the top of his stentorian lungs.www.nmqkl.com.cn
