Textile, printing and dyeing, paper mill wastewater treatment wastewater treatment 010-57193076 --- 13436502885 dehydration textile industry with a flocculant polyacrylamide flocculant. Textile industry is a large industrial wastewater discharge. Wastewater contains a variety of dyes, pulp and surfactant additives, characterized by a high concentration of organic matter, complex composition, can poor biodegradability, high color and changeable, water quality and quantity changes, are difficult to deal with industrial waste . We may have thought that in our beautiful dressed in colorful costumes behind, how many need to dyeing wastewater treatment, and how much water will be polluted. Dyeing wastewater treatment process commonly divided into two categories: one, materialized: the use of added flocculant, coagulant precipitation or flotation in a specific structure, the physical removal of a chemical treatment of wastewater contaminants . But these methods due to the high cost of dosing, not completely remove contaminants and sludge volume and difficult to further process, will produce a certain "secondary pollution" is generally not used alone, only as a secondary biological treatment process. 2, biochemical methods: the use of the role of microorganisms in the sewage organic matter degradation, is adsorbed and removed by a treatment method. Due to its complete degradation of pollutants, relatively low operating costs, basically does not have a "secondary pollution", etc., are widely used in printing and dyeing wastewater treatment. Textile industry flocculant dehydration process, the million students suggested the use of anionic polyacrylamide, cationic polyacrylamide chosen as the sludge dehydrating agent used when the sludge dehydration.
