水处理方面的英文

如何用物理法处理污水？ 处理处理法就是利用物理作用除去污水的漂浮物、悬浮物和油污等，同时从废水中回收有用物质的一种简单水处理法。常用于水处理的物理方法有重力分离、过滤、蒸发结晶和物理调节等方法。重力分离法指利用污水中泥沙、悬浮固体和油类等在重力作用下与水分离的特性，经过自然沉降，将污水中比重较大的悬浮物除去；离心分离法指在机械高速旋转的离心作用下，把不同质量的悬浮物或乳化油通过不同出口分别引流出来，进行回收；过滤法是用石英沙、筛网、尼龙布、隔栅等作过滤介质，对悬浮物进行截留；蒸发结晶法是加热使污水中的水气化，固体物得到浓缩结晶；磁力分离法是利用磁场力的作用，快速除去废水中难于分离的细小悬浮物和胶体，如油、重金属离子、藻类、细菌、病毒等污染物质。
How physics sewage treatment?Handling sewage treatment is the use of physical action to remove floating objects, such as suspended solids and oil. Meanwhile useful substances from water waste a simple treatment method. Gravity methods commonly used in the treatment of the physical separation, filtration, evaporation and crystallization method and physical conditioning. Gravity separation refers to the use of sewage sediment, suspended solids and other oil-water separation under the force of gravity and the characteristics After Settlement, a large proportion of sewage to remove suspended solids; centrifugal separation refers to the high-speed rotating mach
