Environmental Engineering

Every environmental engineer eventually designs a wet scrubber. Whether it’s for acid gas removal (HCl, SO₂, HF), particulate control, or […]

A single 50L compressed gas cylinder at 200 bar contains the energy equivalent of 1.5 kg of TNT. When a

This is the 100th article on GreenEngGuide. When I started this site in May 2026, I had one goal: write

When a chemical plant or battery factory generates hazardous waste that can’t be landfilled, the rotary kiln incinerator is often

Groundwater contamination is the most expensive environmental liability most industrial facilities face. Unlike air emissions that disperse or wastewater that

> 13年工程师生涯，前10年在画图，最近1年在用AI画图。> 以下内容没有广告，全是自己在用的。 — 去年这个时候，我画一张P&ID图需要一整天。 现在？30分钟。 不是因为我变快了。是因为我把所有重复劳动交给了AI。 我的工具箱（全部免费或白菜价） 1. Claude——我的”第二大脑” 不是ChatGPT。是Claude。 区别在哪？ChatGPT像刚毕业的大学生，什么都能聊但什么都不精。Claude像一个有20年经验的高级工程师——你给它一份环评报告，它能帮你找出5个合规漏洞；你给它一张设备数据表，它能帮你写采购技术规格书。 我每天用Claude做这些事： 读标准规范：把200页的GB标准扔给它，”帮我总结和旧版的10个主要变化” 写技术方案：”根据这个水质数据，写一份MBR工艺方案，2000字，要有设计参数” 翻译设备手册：中译英，5万字的手册，以前要两周，现在半天审校 检查图纸：截图发给它，”这个管道布置有违反规范的地方吗？” 关键技巧：把AI当成你的实习生。给它明确的指令、上下文、输出格式。不要问”怎么设计废水站”，要问”根据进水COD 3000、出水要求COD 50，推荐工艺路线并给出设计参数”。

Before you design a wastewater treatment plant on that “brownfield” parcel, before you expand your factory onto the adjacent lot,

After 13 years in environmental engineering, I’ve designed, commissioned, and debugged more acid scrubbers than I can count. From HCl

Electroplating wastewater is not one wastewater. It’s at least three chemically incompatible streams that must be collected, stored, and treated

A dust collection system that doesn’t capture dust at the source is just an expensive fan moving dirty air around

The A²O process—Anaerobic-Anoxic-Oxic—is the most widely deployed biological nutrient removal (BNR) configuration in the world. It removes organic carbon, nitrogen,
