TREATMENT TECHNOLOGY FOR SYNTHETIC LEATHER PRODUCTION WASTEWATER

摘要

A treatment technology for synthetic leather production wastewater, sequentially comprising: grating treatment, pH and temperature regulation, blow-off treatment, air-flotation treatment, domestic sewage anaerobic degradation, aerobic degradation, sedimentation, and MBR treatment. By adopting the technology, the stability of water quality in degradation by an aerobic biological method is ensured, the technological requirements at a later stage are reduced, and the effluent quality is ensured; the removing rate of dimethylamine after blow-off treatment is up to 81%, thereby well solving the problem of a foul smell of distilled wastewater, being able to recycle the dimethylamine in the wastewater, and changing the wastewater into wealth; and the wastewater is discharged up to standard. Also disclosed is a treatment system of synthetic leather production wastewater.
