本课只做一件事:搞清「空气与水污染控制」到底是什么、为什么考试要先过这一关、它管到哪里为止。

Get clear on what Air & Water Pollution Control really is, why it comes first, and where it stops.

本课不涉及:不展开细节与题目——那是第 2–5 课的事。
Not covered here: No detail, no questions — those are lessons 2 to 5.

本课目标 | Learning objectives

  1. 能用一句话说清「空气与水污染控制」解决的是什么问题
  2. 能举出一个「不懂它就一定做错」的例子
  3. 知道本课的边界,不把后续课的内容提前混进来

  • State in one sentence the problem Air & Water Pollution Control solves
  • Give one example where missing it guarantees a wrong answer
  • Know this lesson's boundary and keep later lessons out

    它是什么 | What it is

    污染控制设备选型的逻辑只有三句话:颗粒看粒径、气体看性质、废水看负荷。除尘谱系按粒径从粗到细排列——重力沉降(>50 μm)→ 旋风(>10 μm,常做预处理)→ 袋滤/布袋(细粉与亚微米级主力)→ 湿式洗涤(可燃气尘、黏性尘,顺带降温)→ 静电除尘(大风量细颗粒,压损最低);运行健康度看压差趋势。气体净化三路线:吸收(洗涤塔,对付酸碱气与氨)、吸附(活性炭,低浓度大风量 VOC 的经典经济解,可脱附回收)、燃烧(RTO/催化,可燃 VOC)。废水处理四级:隔栅与调节(匀质匀量)→ 一级物化(沉砂、混凝、pH 中和)→ 二级生化(降 BOD/COD 的主战场)→ 三级深度(脱氮除磷、过滤回用),pH 调节贯穿全程。两条红线:雨水不得串入工艺废水——串流等于无许可排放,SWPPP 与 BMP 要落到现场;存量建筑风险(石棉保温与吊顶、铅漆、地下储罐)在扰动前先检测,由持证方按法规处置。

    Control selection comes down to three lines: particle size for dust, gas nature for vapours, and load for wastewater. The dust train runs coarse to fine — gravity settlers above 50 microns, cyclones above 10 as pretreatment, baghouses for fine and sub-micron dust, wet scrubbers for sticky or combustible dust with cooling, and electrostatic precipitators for high-flow fine particulate at the lowest pressure drop; pressure-drop trend is the health gauge. Gas cleaning offers three routes: absorption towers for acid and ammonia, activated-carbon adsorption for high-flow low-concentration VOC with regenerable recovery, and thermal or catalytic oxidation for combustible VOC. The wastewater train is screening and equalization, primary physical-chemical, secondary biological for BOD and COD, and tertiary polishing — with pH control throughout. Two red lines: stormwater must never cross into process waste, which is an unpermitted discharge, with SWPPP and BMPs on the ground; and legacy risks — asbestos, lead paint, underground tanks — get tested before disturbance and handled by licensed contractors.

    为什么先学它 / Why first
    三个坑:①按「效率最高」选设备——离心机配静电除尘对付 80 μm 粗尘纯属浪费,选型先看粒径分布;②VOC 一律上 RTO——低浓度大风量时燃料费远超活性炭脱附回收,先算浓度与风量再选路线;③雨水管当废水管用——场地冲洗水进雨水口就是无许可排放,罚单比处理费贵一个量级。
    Three traps: picking the most efficient device regardless of size distribution — an ESP for 80-micron grit is money burned; defaulting to RTO when low-concentration high-flow VOC is carbon adsorption territory; and rinsing floors into storm drains, which turns a cleanup into an unpermitted discharge an order of magnitude costlier.
    它管到哪里为止 / Where it stops
    本块以选型逻辑与判定为主,不展开设备设计计算(ESP 电场、塔径)、专利型工艺与具体排放标准的限值推导。
    Selection logic is the scope; equipment design math and patent-specific processes are not developed.

    情景自测 | Scenario check

    本课理解Lesson comprehension

    这道题考什么:考选型的第一判据。
    Tests the first selection criterion.

    含苯废气浓度低、风量大。最经济的控制方案是?

    Benzene-laden off-gas at high flow and low concentration. Most economical control?

    自编练习题,不是 BCSP 官方真题,也不能用来预测分数。 / Original practice item, not an official BCSP exam question.

    动手练 | Practice

    1. 画你厂的除尘设备谱系并标注各台的设计粒径段。
    Sketch your dust train and mark each unit's design particle band.
