WASTEWATER TREATMENT SYSTEMS WITH HIGH CONCENTRATIONS OF RECYCLE-DEGRADABLE ORGANIC SUBSTANCES

Abstract

The invention is a proposal for a wastewater treatment system with high concentrations of difficult-to-decompose organic matter, including: a collection tank (1), a balancing tank (2), a physico-chemical treatment unit (3), a biological treatment unit (4), an advanced oxidation treatment unit (5), a disinfection tank (6), a fine treatment unit (7), a chemical supply unit (8), a sludge treatment unit (9), a post-treatment water storage tank (10), and a central control unit (11), in which the physico-chemical treatment, biological treatment and fine treatment stages are arranged in a reasonable sequence to reduce the load on the biological treatment process, improve treatment efficiency, ensure stable post-treatment water quality, and create favorable conditions for water reuse in production stages.
