1. A screen is installed at the inlet of the wastewater treatment system to remove large floating objects, branches, weeds, wood chips, plastic waste, and domestic garbage, protecting the safe operation of pumps and reducing the load on subsequent processes. 2. Wastewater flows by gravity into a collection tank after
Treatment methods include: activated sludge process, bio-enhanced technology, supercritical water oxidation, etc. These methods aim to reduce wastewater generation at its source, eventually reaching zero, which is known as coking wastewater reduction technology. Specifically: 1. Crude benzene separation water: Treatment method: negative pressure distillation. This lowers the boiling point of
distillation, purification, and by-product recovery processes of coking and coal gas production. It contains volatile phenols, polycyclic aromatic hydrocarbons, and heterocyclic compounds such as oxygen, sulfur, and nitrogen. It is a type of industrial organic wastewater with high CODcr, high phenol value, high ammonia nitrogen, and is difficult to treat.
