Abstract

The invention discloses a cosmetic wastewater deep treatment recycling method. The method is characterized by including the steps of: (1) wastewater preconditioning; (2) oxidation reaction; (3) aerobic treatment; (4) flocculation precipitation; and (5) preparation of recycling water. An oxidation reagent can decompose difficultly biodegradable organic matters, by adding PAM to conduct flocculation settlement and deep treatment, the effluent water suspended solids (SS) are less than 60mg / L, the chroma is smaller than40 times, the COD is less than 100mg / L, nanoscale Ti0 and carrier filler composed of 80-90mesh powdery coal-based activated carbon have a large specific surface area, high volume load, high oxygen utilization, and excellent purification performance, can guarantee the quality of effluent water and ease the situation of fresh water resource shortage. Thus, the method is a water-saving, green and environmental protection technology.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a method for advanced treatment and recycling of cosmetic wastewater. Background technique [0002] In the current situation of severe shortage of water resources and increasing water pollution control in my country, in order to improve the recycling of wastewater, alleviate the situation of water shortage, and ensure the sustainable development of the cosmetics industry, the reuse and treatment of cosmetic wastewater has become an important part of this field. development trend. [0003] Cosmetic wastewater contains a large amount of suspended solids and various pollutants, and has the characteristics of high COD, BOD, SS and LAS. It is difficult to meet the emission standards by simply using physical and chemical treatment, but if only biochemical treatment is used, the investment will be large and the floor area will be large, and the oil and LAS in th...
