Textile printing and dyeing industry is major emitters in the industrial wastewater, sewage mainly contain the textile fiber in the dirt, grease, salts and additional in the manufacturing process of all kinds of slurry, dye, surface active agent, additives, ph, etc.
textile wastewater mainly raw materials in the process of cooking, rinsing, bleaching and sizing with natural impurities, fat and starch and other organic wastewater. Printing and dyeing wastewater is in the washing and dyeing, printing, sizing process, contains a lot of dyestuff, starch, cellulose, lignin, detergents and other organic matter, and inorganic substances such as alkali, sulfide, all kinds of salty polluting is very strong.
with the development of textile and dyeing industry, the environmental impact of printing and dyeing wastewater is sudden, printing and dyeing industry wastewater treatment research and development also constantly get into application.

textile printing and dyeing wastewater classification according to the production process, the project of wastewater could be divided into two kinds of refining bleaching wastewater and printing and dyeing wastewater:
( 1) Refining bleaching wastewater
mainly include: knitted fabric in scouring and bleaching wastewater produced during processing. This kind of wastewater is mainly suspended solid concentration is higher, low chroma.
( 2) Printing and dyeing wastewater
mainly include: knitted fabric in the process of printing and dyeing wastewater. This kind of wastewater is mainly suspended solid concentration is low, high chromaticity.
all kinds of textile printing and dyeing wastewater (
1) Cotton fabric printing and dyeing wastewater (cotton textile printing and dyeing wastewater Including pretreatment process, dyeing or printing and finishing processes) Are organic wastewater, the main components in synthetic organic compounds and part of natural organic matter, and contains a certain amount to biodegradable material.
   ( 2) Wool textile printing and dyeing wastewater in the dyeing process of wool textile products mainly use acid dyes, dye uptake rate is higher, the shade of the dyeing waste water is relatively low. Wool textile dyeing wastewater biodegradability of products is good, very suitable for using biochemical processing.
   ( 3) Pure silk printing and dyeing wastewater to neutral silk textile printing and dyeing wastewater, organic wastewater biodegradability, organic matter content in the wastewater is relatively lower.
   ( 4) Linen textile printing and dyeing wastewater jute spinning fiber cellulose fibre and its degumming waste water produced during processing and printing and dyeing wastewater. Degumming jute spinning production process wastewater of high concentration organic wastewater, easily biodegradable.
textile printing and dyeing industry wastewater containing phenol removal process
with centrifugal extraction machine textile printing and dyeing industry wastewater containing phenol in wastewater treatment, the equipment is small in size, high efficiency, small dosage of extraction agent, the characteristics of can save a lot of the cost of extracting agent, removing phenol rate above 98%. The current domestic companies in industrial wastewater emissions about 40 billion tons, including industrial waste water containing phenol about 0. Around 5%, about 2 billion tons. According to market research and forecasts domestic emissions of industrial waste water containing phenol centrifugal extraction machine processing can be used about 30% of the total phenol waste water, it will be altogether centrifugal extraction machine more than one thousand units.
