▎ 摘　　要

NOVELTY - High-concentration pollutant wastewater treatment system, comprises wastewater pre-treatment subsystem, wastewater biochemical treatment subsystem and wastewater depth processing subsystem. The wastewater pre-treatment subsystem mainly includes photocatalysis-light Fenton combined device, wastewater biochemical treatment subsystem mainly includes anaerobic treatment device, aerobic treatment device or combined device, according to water quality requirement of biochemical treatment, depth processing subsystem mainly includes photo-catalytic device, light Fenton device, chemical oxidation device, physical adsorption device or combined device; chemical oxygen demand (COD) value is 10000-20000 mg/l, biological oxygen demand over 5 days (BOD5)/COD is 0.05-0.2 of high-concentration new pollutant wastewater can reach the discharge standard through fractional treatment. USE - The system is useful in the field of chemical and medicinal environmental protection. ADVANTAGE - The system can meet the needs of chemical and medicinal high-concentration pollutant wastewater treatment and improves the processing ability of existing biochemical wastewater treatment system.
