Hair product industry dyeing liquid wastewater recycling and reuse treatment device and operation method thereof

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of dyeing liquid wastewater treatment, and in particular relates to a dyeing liquid wastewater recycling treatment device in the hair product industry and an operating method thereof. Background technique [0002] The 21st century is the century of global population aging. At present, my country has gradually entered the age of aging. With the continuous expansion of the silver-haired team, the demand for wig products continues to grow; on the other hand, with the gradual improvement of consumption levels and quality of life, people's requirements for beauty and image are stronger, and more and more young people are more interested in hairstyle decoration. The pursuit breeds a boom in wig products. Statistics show that the global hair products market size in 2013 was approximately US$9.72 billion, with an annual growth rate of 15.1%. The production process of the hair products industry consumes a lot of wa...

Problems solved by technology

[0004] In order to solve the problem that the dyeing liquid in the existing hair products industry is discharged without effective treatment after one use, which not only wastes water resources but also causes serious pollution to the environment, it provides a main body and supporting equipment with a compact structure, complete functions, and easy to use. The hair product industry dyeing liquid waste water recycling treatment device and its operation method, which can be operated and maintained in a flexible arrangement, take the dyeing process with a large amount of wastewater as the research object, combined with the research results of the dyeing liquid reuse technology in the hair product industry, adopt Antibacterial ultrafiltration membrane and reverse osmosis membrane double-membrane combination technology reuses the dyeing liquid wastewater after in-situ water quality improvement, making the dyeing liquid reuse rate as high as 80%, thereby effectively saving fresh water consumption and basically reaching the waste water. Zero discharge and the purpose of dye reuse
