Hairwork waste water cyclic utilization device and treatment method thereof

Abstract

The invention discloses a hairwork waste water cyclic utilization device and a treatment method thereof, which relate to the regenerating cyclic utilization of waste water. The device is provided with a screen well, a collector well, a water pump, an aeration adjusting tank, a hair filter, a coagulating tank, a flocculation tank, a primary settling tank, an electrolysis machine, a hydrolysis acidification tank, an anoxic tank, an aerobic tank, a nitrification tank, a secondary settling tank, a sludge tank, a sludge dewatering device, a filtering device and a desalter. The waste water can reach an industrial water standard through mutually matching all devices. The treatment method comprises the following steps: flocculating settling, electrolysis, anaerobic treatment, aerobic treatment, settling, filtering and desalting. Through the treatment method, regenerated water can reach the industrial water requirement of industrial production, the discharge of the waste water is reduced, the consumption of a chemical agent is low, the running cost is low, and the use ratio of the waste water is high.

Description

technical field [0001] The invention relates to a waste water recycling treatment, in particular to a hair product waste water recycling device and a treatment method thereof, belonging to the field of environmental engineering. Background technique [0002] Wig products (commonly known as hair products or hair extensions) are made from human hair, animal hair and chemical fibers through pickling, washing, bleaching, dyeing and washing processes. refer to figure 1 , figure 1 The production process of wig products is based on human hair and animal hair. refer to figure 2 , figure 2 The production process of wig products is based on chemical fiber as raw material. [0003] The wastewater generated during the production of wig products is commonly known as hair product wastewater or hair file wastewater. The main sources are: acid-containing wastewater generated in the acid etching process, that is, soaking the grease and dirt on the hair with sulfuric acid, and then neu...
