| Zusammenfassung: | The invention provides a reclaimed water reuse system for leather wastewater and belongs to the field of reclaimed water reuse. The system comprises a pretreatment system, a reaction system and a regeneration treatment system, wherein the pretreatment system comprises an A/O biofilter with oyster shell filler and a zeolite filter; the reaction system comprises a zeolite filler reaction tank and anion exchange tank; the regeneration treatment system realizes regeneration of the zeolite filler reaction tank and the ion exchange tank by processes such as hydrochloric acid soaking regeneration, brine soaking regeneration and air-water backwashing. According to the reclaimed water reuse system, the leather wastewater after secondary biochemical treatment can be further treated to meet the requirement of reclaimed water reuse standards, and can be reused for cleaning workshops and irrigating plant green lands, so that win-win recycling and emission reduction of the wastewater are achieved.
