场景走一遍 | Walk the scenario

喷涂车间扩建后，喷漆房排风 30000 m³/h，VOC 浓度约 120 mg/m³（主要是甲苯与二甲苯），现有水帘柜只做漆雾拦截；厂区雨水排口附近地面常有漆渣与稀释剂桶堆放；仓库屋面正在翻新，涉及 1985 年安装的吊顶保温。你是 EHS。

After expansion, the spray booth exhausts 30,000 m³/h at about 120 mg/m³ VOC (toluene and xylene), with only a water curtain for overspray; drums of thinner and paint residue sit near the stormwater outfall; and a 1985-vintage insulated ceiling is being renovated. You are EHS.

1. 第一步：定口径——先算排放量（30000×120 mg/m³ ≈ 3.6 kg/h，年 8000 h ≈ 29 t）核对是否触发许可修改与 TRI 申报；按「低浓度大风量+可回收溶剂」判据选定活性炭吸附（脱附回收或达标换炭）为控制方案，水帘柜保留做漆雾预处理。测算与方案成文，作为许可修改附件。 — Step 1 — size the problem: compute emissions (3.6 kg/h, about 29 t a year) and check permit modification and TRI thresholds; apply the criteria — high flow, low concentration, recoverable solvent — and select carbon adsorption with regeneration or carbon swap, keeping the water curtain as overspray pretreatment. Write it up as the permit-modification attachment.
2. 第二步：断雨水污染路径——把稀释剂桶与漆渣移出雨水口汇水区并入棚存放；雨水口加装滤网与围挡，场地改干式清扫；核对 SWPPP 的 BMP 清单并更新（新堆放区、新增监测点）；明确「冲洗水只能进工艺废水系统」并写进 SOP 与培训。 — Step 2 — cut the stormwater path: move drums and residue out of the outfall catchment under cover; fit drain guards and switch to dry sweeping; update the SWPPP BMP list and monitoring points; and write 'rinse water goes to the process sewer only' into the SOP and training.
3. 第三步：管住翻新现场的存量风险——暂停吊顶作业，取样送检石棉；若 ACM 判定成立，由持证承包商按法规（湿法作业、负压隔离、双层袋装、manifest）处置，作业区张贴警示并限制进入；铅漆一并检测。恢复施工前把「检测报告+处置记录+清场确认」归档，同时把喷漆房改造排入下季度环保台账。 — Step 3 — manage legacy risk in the renovation: pause ceiling work and sample for asbestos; if ACM is confirmed, a licensed contractor handles it wet, under negative pressure, double-bagged with a manifest, with warning signs and access control; test lead paint too. Archive the survey, disposal records and clearance before work resumes, and log the booth retrofit in the environmental ledger.

走完这三步再往下答题；答案不是背出来的，是按步骤推出来的。/ Work the three steps before answering — the answer is derived, not recalled.
