现代废水处理技术，按作用原理可分为物理法、化学法、物理化学法和生物 法四大类。 物理法是利用物理作用来分离废水中的悬浮物或乳浊物。常见的有格栅、筛 滤、离心、澄清、过滤、隔油等方法

水中污染物在水中生物（主要是水中微生物）的 作用下，其性质或存在位置（状态）发生变化。其主 要过程就是水生物对水中污染物的利用过程。主要原 因是水中生物将某种（些）污染物作为自己的食物及 营养（能量）的来源，它们消耗利用了水中的这种 （些）污染物，起到了净化水质的作用

只对水中污染物的存在位置变化产生作用，而不对其 性质变化产生作用。其主要过程（作用）包括：移流（推 流、对流）、扩散（包括紊动扩散和离散等）、沉降或再 悬浮，以上过程（及作用）常称稀释混合

1、《固体废物污染环境防治法》的污染防治对象包括（ ） A、 危险废物 B、 液态废物 C、 工业固体废物 D、 城市生活垃圾 E、 置于容器内的气态废物
