The screen stops big pieces of waste. The fine screen catches tiny bits of trash. Then, the water goes into a sedimentation tank. Here, tiny sand particles settle down and are removed. Next, the wastewater moves to anaerobic, anoxic, and aerobic tanks. Microorganisms in these tanks break down impurities in the water. Finally, the treated water goes to an ultraviolet disinfection tank. After disinfection, the water becomes much cleaner and can be reused. 首先，污水要通过粗格栅和细格栅。粗格栅就像一位“大垃圾捕手”，拦住大块垃圾；细栅栏像一位明察秋毫的“小卫士”，将污水里的细碎杂物精准拦截。接着，污水会进入沉淀池，将细小的沙子沉淀排出。随后，污水流入厌氧池、缺氧池和好氧池。它们可是为微生物提供了舒适的“家”,微生物在这样的环境里分解污水里的杂质。最后，处理后的水会来到紫外线消毒池，经过消毒变得更加清澈，最终成为可以再次利用的水。 Post reading Post reading 1. process n. 过程 learning/cleaning process 学习/清洁过程 the process of ...的过程 e.g. Lehning talked about the process of making the song. 莱宁讲述了这首歌的制作过程。 v. 加工 e.g. The fruit is processed into juice. 水果被加工成果汁。 2. learn/know about sth 了解 learn to do sth 学习做某事 Notes 3. see sb do sth 看见某人做某事（全过程/经常） see sb doing sth 看见某人正在...
