What are the pollutants caused by chemical factories?

The pollution in chemical factories is indeed a complex issue, let me help you clarify it. Simply put, it is mainly divided into three categories: exhaust gas, wastewater, and waste residue, each of which may cause serious environmental problems.
1、 Waste gas pollution
Main pollutants: including smoke, sulfur dioxide, nitrogen oxides, volatile organic compounds (VOCs), toxic gases (such as chlorine and ammonia), etc.
Source: Inorganic chemical waste gas mainly comes from enterprises such as acid, alkali, and fertilizer production; Organic chemical waste gas mainly comes from petrochemical and coal chemical industries.
2、 Wastewater pollution
Main pollutants: organic wastewater (such as phenol and aldehyde wastewater), inorganic wastewater (such as heavy metal and acid-base wastewater), toxic and harmful substance wastewater, suspended solids wastewater, etc.
Characteristics: Harmful, oxygen consuming, acid-base, eutrophic, oil film covering, etc.
3、 Waste residue pollution
Main pollutants: Industrial waste generated during chemical production processes, such as waste catalysts, reaction residues, distillation residues, etc.
Characteristics: The quantity is increasing day by day, and passive stacking will occupy land, pollute soil, water sources, and the atmosphere.
4、 Pollution characteristics
There are many types: covering three forms: gas, liquid, and solid.
Wide range of pollution: easy to spread through various pathways such as water, air, and soil.
The toxicity of pollutants is high: some have carcinogenic, teratogenic, mutagenic effects, and may have long-term environmental impacts.
Large discharge volume and complex composition: often containing multiple chemical substances, making treatment difficult.
