Description
Technical field
The invention belongs to fine chemistry industry and field of environment protection, more specifically relate to a kind of quaternary ammonium salt cationic type organic polymer coargulator and preparation method thereof.
Background technology
Along with increasing rapidly of China's economy, more and more enterprises is about to face the problem of shortage of water resources, and meanwhile, water environment pollution is also more and more serious.Paper industry and dyeing are the water rich anies influential family of two great traditions, also are the important source of pollution that cause water pollution.At present, China's paper-making industry is in the period of high speed development, it is reported that the production and consumption average year amplification of China's paper industry is 18% over nearly 10 years.But be limited by the deficiency of fund and technology, China's paper-making industry production technology generally lags behind developed country, utilization rate of raw materials is not high, and intermediate products a large amount of in the paper process do not change into product, are discharged into the pollutent that becomes the serious harm environment in the factory effluent.Simultaneously, along with developing rapidly of printing and dyeing and dyestuffs industries, the pollution problem that waste water from dyestuff brought is serious day by day.Characteristics such as this class waste water has that the water yield is big, complicated component, the organic pollutant content height of difficult degradation, colourity are dark.According to statistics, the quantity discharged of China's paper-making industrial waste water and dyeing waste water and COD
CrQuantity discharged occupies the first place of domestic other kinds industrial discharge amount, its pollution to water surrounding is the most serious, therefore, paper waste and dyeing waste water are effectively handled, the matter of utmost importance of paper industry and dyeing prevention and cure of pollution still is not the matter of utmost importance that national trade effluent carries out processing up to standard yet.。
