Description
Technical field
The invention belongs to technical field of sewage, and in particular to a kind of cosmetics sewage treatment process.
Background technique
With the development of national economy, cosmetics gradually become the necessity of home life, and the production of cosmetics
Journey also brings certain pollution to resource environment.Cosmetics sewage is mainly from cleaning flushing waste water and product processing
Process drain.These cosmetics sewage have the following characteristics that (1) sewage quantity is generally little, but pollutant year concentration it is higher.It is dirty
COD concentration is about 10000~15000mg/L in water, and the concentration of BOD is also up to thousands of mg/L, if do not dealt carefully with, it will to ring
Cause serious pollution and destruction in border.(2) sewage composition is complicated: mainly due to material composition complexity, in addition, cosmetics are from raw material
The long flow path of finished product to the end is produced, by-product is more, leads to the various complexity of contaminant component, Colority of Sewage Water is higher, more increases
The difficulty of sewage treatment.(3) bio-refractory substance is more: the organic pollutant in sewage largely belongs to bio-refractory object
Matter, such as glycerol octadecyl alcolol, half glycerol grease pollutant and some cosmetic additive agents, emulsification degree are higher.(4)
Poisonous and harmful substance is more: the organic contamination of many of sewage is poisonous and harmful to microorganism, such as the phenylenediamine in hair dye, silty
Lead, mercury, arsenic in cosmetic remove quinhydrones and its derivative in the sun-proof equal cosmetics of freckle, the phthalic acid junket in nail polish
Deng.
Due to the above feature, so that cosmetics sewage has caused environmental protection sector to the very harmful of ecological environment
Person's concern.Chinese invention patent CN109052816A discloses a kind of cosmetics waste water treatment process, carries out in the following order useless
Water process, after conditioning tank, dosing reactive tank, diaphragm filter press, filter liquid pool, anaerobic digester, anaerobic precipitation pond, anoxic pond,
Membrane biological reaction pond, intermediate pool, COD resin container to reuse sink, through the waste water treatment process, treated although waste water reaches
Discharge standard has been arrived, but treatment process is more complex, occupied area is wide, higher cost.
Since cosmetics sewage treatment difficulty is larger, higher cost, technique is taken up a large area, and system operation energy consumption is high, dimension
Shield is difficult, how to develop a kind of simple process, efficiently, sewage treatment process easy to operate, at low cost has become currentization
The important research direction of cosmetic sewage treatment field.
Summary of the invention
In order to solve the problems in the existing technology, the purpose of the present invention is to provide a kind of cosmetics sewage treatment works
Skill.Cosmetics sewage treatment process provided by the invention, it is excellent to the removal effect of the organic pollutant in cosmetics sewage, out
