Chemical wastewater treatment solution

Industry Status

Wastewater in the chemical industry refers to the wastewater generated during the production process of chemical plants—for example, oil-containing wastewater from facilities such as ethylene, polyethylene, rubber, polyester, methanol, ethylene glycol, oil product tank farms, and air separation/pressure stations. After biological treatment, it can generally meet the national second-level discharge standard.

The main pollution factors of chemical industry wastewater are: pH, SS (suspended solids), and TP (total phosphorus). Discharging such wastewater will cause water acidification and water eutrophication.

For chemical industry wastewater treatment: due to water resource shortages, wastewater that has met discharge standards now needs further advanced treatment to meet the requirements of industrial make-up water and be reused.

To effectively treat chemical production wastewater, feasible and cost-effective treatment plans should be adopted based on the specific water quality, water volume, and local environmental conditions. We should try to separate and recover valuable resources from wastewater while treating it.
