Water Purification by Hydrophytes and Change of Microorganism in Root Zone and Water The Purification Functions of a Biological Cleaning Agent on Aquaculture Water of Chinese Mitten Crab 水生植物净化中微生物变化及净化效果研究一种生物净水剂对河蟹养殖水体水质净化效果研究
The dynamic pressure and turbulent kinetic energy contours showed that a strong turbulent zone was formed by tar particles carrying with gas stream impacted detergent droplet, which promoted purification efficiency of tar. 由等动压与湍流动能分布云图得出:燃气流携带焦油颗粒冲击碰撞洗涤剂液滴形成强烈的湍流区,促进了焦油的净化,但也是造成文丘里洗涤器压力损耗的主要区域。
Urban waterfront is the zone of most natural activities in a city. Microclimate adjustment of the river, purification ability of the water system and green plant community are bringing city endless advantages. 城市滨水区是城市中自然活动最为频繁的地带,河流的微气候调节、水体的净化能力、绿色植物群落都给城市带来无尽的好处。
