本课只做一件事：用 5 道题检验「空气与水污染控制」，并把错的那几道归到具体原因上。
Test Air & Water Pollution Control with five items and trace every miss to a specific cause.
本课不涉及：不出新知识点——只检验前四课学过的内容。
Not covered here: No new material — only what lessons 1 to 4 covered.

The classic economical fix for high-flow low-concentration VOC?
3. 废水二级生化的主要任务是？

5. 1985 年吊顶保温翻新前必须？

错因归类 | Sort your misses
- 按效率选设备 → 粒径不合则高效设备也是浪费Choosing equipment by efficiency alone → wrong particle size makes even high-efficiency gear a waste
- VOC 一律 RTO → 低浓度大风量燃料费失控，先算经济账RTO for all VOC streams → at low concentration and high flow, fuel costs blow up; run the numbers first
- 稀释进雨水管 → 判定看性质与去向，不看浓度Diluting into the storm drain → determination depends on the nature and destination, not the concentration
接下来学什么：下一块（Day 282–286）继续 Domain 5：危化品环境释放与应急——先报告、再围堵、后清污，全程留证。
Next block (Days 282–286) continues Domain 5: chemical releases and environmental emergency — report, contain, clean, and document all of it.
