Technology Selection And Effect Evaluation Of Water Saving And Emission Reduction In Production Process Of Hair Products

Hair products are made of human hair,chemical fiber,animal hair as raw material,after a series of processing from the wig products,according to its function can be divided into winding,hair sets,hair blocks,accessories hair,learning head.At present,China is the world’s largest producer of hair products,exports showed a sustained upward trend.However,the waste water produced by the production of the product contains a variety of organic pollution components such as oils and fats,amino acids,surfactants,dyes and various additives,and the color,COD,NH3-N content is high,and the biodegradability is poor,The row will seriously pollute the environment.Hair products industry has a low level of water saving,intermittent waste water discharge,changes in pH,high color and complex composition,high ammonia nitrogen content,including biological inhibitory pollutants and other characteristics,with a large clean production level to enhance the space.This paper analyzes the problems existing in the production process of traditional hair products from the perspective of water saving and emission reduction,and discusses the potential of water saving and emission reduction of hair products enterprises and the measures The feasibility of the project for the enterprises to improve water use efficiency,to achieve cleaner production to provide reference and reference.Through the new hair products experimental study to find the best process parameters for the hair products industry to provide technical support for water-saving emission reduction work.The main contents of this paper include:(1)through the in-depth research and development of products manufacturing process and pollution status,to identify the main pollution generation and water consumption.(2)combined with the findings and the results of water quality analysis,the final selection of waste water in situ reuse,waste water echelon and continuous countercurrent washing process as the mainproduction of water-saving emission reduction measures.(3)By implementing the above three kinds of water saving and emission reduction technologies in the production of the whole hair products,the whole water recycling of the production enterprises can be fully recycled.The overall water saving rate can reach 28%,reduce the ammonia consumption by 20%Ammonium sulfate dosage 20%-40%,water-saving emission reduction effect is obvious.
