Problems solved by technology

The concentration of COD in sewage is about 10,000-15,000 mg/L, and the concentration of BOD is as high as several thousand mg/L. If it is not treated properly, it will cause serious pollution and damage to the environment.
(2) The composition of sewage is complex: mainly due to the complex composition of raw materials. In addition, the process of cosmetics from raw material production to final product is long and there are many by-products, resulting in complex pollutant components and high chroma of sewage, which further increases the cost of sewage treatment. difficulty
Chinese invention patent CN109052816A discloses a cosmetic wastewater treatment process. Wastewater treatment is carried out in the following order, through the adjustment tank, the dosing reaction

Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to a cosmetic sewage treatment process. According to the cosmetic sewage treatment process provided by the invention, cosmetic sewage successively passes through a flocculation sedimentation tank, an intermediate water tank, a hydrolysis acidification tank, a pH adjustment tank, an anaerobic tank, a biological contact oxidation tank, a secondary sedimentation tank and a clean water tank, and is finally subjected to up-to-standard discharge. According to the cosmetic sewage treatment process provided by the invention, the removal effect on organic pollutants in the cosmetic sewage is excellent, effluent discharge can reach the primary standard in the second period of Guang dong Province 'Water Pollutant Discharge Limit' (DB44/26-2001), meanwhile, the process is simple, efficient and easy to operate, the floor area is small, the cost is low, and operation benefits of enterprises and sewage treatment plants can be effectively increased.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a cosmetic sewage treatment process. Background technique [0002] With the development of the national economy, cosmetics have gradually become a necessity for home life, and the production process of cosmetics has also brought certain pollution to resources and the environment. Cosmetic sewage mainly comes from washing and flushing wastewater and process drainage during product processing. These cosmetic sewage have the following characteristics: (1) The amount of sewage is generally small, but the annual concentration of pollutants is relatively high. The concentration of COD in sewage is about 10,000-15,000 mg / L, and the concentration of BOD is as high as several thousand mg / L. If it is not treated properly, it will cause serious pollution and damage to the environment. (2) The composition of sewage is complex: mainly due to the complex composition of r...
