Selection And Research On Clean Production Technology Of Water Saving And Emission Reduction In Hair Products Industry

The definition of hair products on the human hair,fiber or animal hair as raw materials,the formation of wig products through some complex processes,according to the use of function or processing division,can be divided into clockwork,sleeve,hair piece,hair accessories,mannequin.China is now the largest producer of hair products in the world,and the export volume is on the rise.However,at present,the production mode of hair products is still extensive.The water consumption in the production process is large.The wastewater can not be biochemically well,and contains a lot of acids,alkalis,surfactants,dyes,Oils and amino acids and other substances,which increases the difficulty of wastewater treatment.Based on the on-site survey of hair products enterprise,carries on the discussion and Research on the main process of water consumption,emissions from large consumption in the production process,put forward the improvement scheme of energy saving and emission reduction,the optimum process parameters by simulating the actual production to find out the water-saving and emission reduction measures,according to the characteristics of hair products production and processing design and production automation products cleaning equipment.The automatic cleaning equipment used in hair products,hair products enterprise actual production,the continuous improvement of production technology and equipment,the final perfect hair products processing equipment with automatic production,saving time and effort,the treatment process for hair products enterprise water-saving and emission reduction work to play a guiding role.The main contents of this paper are as follows:(1)through the data and field investigation,the present situation of the production process and the pollution of the hair products of the typical hair products is understood.A representative hair product manufacturer was selected for sampling and testing the wastewater of its main pretreatment process.According to the characteristics of water drainage,the consumption links were analyzed,and suggestions for water saving and emission reduction and process improvement were put forward.(2)according to the recommendations and improvement direction of water-saving and emission reduction technology,do the following experiments: explore the hair products before processing main part of the optimal production conditions,the dye and acid leaching solution in situ with ascension back to verify the effect of dyeing,part of the creation of ultrasonic influence on the quality of the finished product was part of the creation of effects of ultrasound on different pH conditions of dyeing.(3)to design and produce a new type of backflow flushing equipment for hair products,and to verify the effect of countercurrent rinsing after neutralization and dyeing.
