Belonging to the technical field of 
dyeing liquid 
wastewater treatment, the invention discloses a hair product industry 
dyeing liquid 
wastewater recycling and reuse treatment device and an operation method thereof. According to the key points of a technical scheme, the treatment device comprises a 
dyeing process dyeing waste liquid 
pool, a dyeing process flushing 
wastewater pool, a dyeing liquid wastewater 
pool, an adjustment pool, a boosting pump, a filter unit, a low pressure pump, a self-cleaning filter, a bacteriostatic modified photocatalytic 
ultrafiltration membrane apparatus, a 
reverse osmosis water inlet case, a 
reverse osmosis boosting pump, a security filter, a high-pressure pump, a 
reverse osmosis membrane apparatus, and a flushing 
liquid storage tank. The invention adopts the dyeing process with large wastewater yield as the 
research object, combines the research results of hair product industry dyeing liquid recycle technologies, employs a bacteriostatic 
ultrafiltration membrane and reverse 
osmosis membrane double-membrane combined technology, performs in-situ 
water quality upgrading on dyeing liquid wastewater to achieve reuse, so that the dyeing liquid 
reuse rate reaches more than 80%, thus effectively saving 
fresh water dosage, and basically achieving the purposes of zero 
discharge of wastewater and reuse of dyes.
