I. Sources of rubber wastewater and chemical composition of pollutants
Rubber wastewater comes from wastewater and flushing wastewater discharged during the rubber processing process, such as rubber tire factory wastewater, rubber recycling wastewater, rubber industrial products factory wastewater, butadiene rubber wastewater, styrene butadiene rubber wastewater, natural latex processing wastewater, rubber emulsion polymerization production wastewater, etc.
The chemical composition of rubber wastewater pollutants is oil, salt, colloidal organic matter COD, ammonia nitrogen, suspended solids, sulfide, heavy metal ions, etc.
II. Rubber wastewater treatment methods
Rubber wastewater implements the "Rubber Products Industry Pollutant Emission Standard" (GB27632-2011)
III. Rubber wastewater treatment methods:
1) Acid-base adjustment tank
2) Chemical coagulation treatment
3) Hydrolysis acidification tank
4) Contact oxidation tank
5) Sedimentation tank
