随着纺织印染业的蓬勃发展，每年，我国印染废水排放量超过17亿立方米。废水中的染料能吸收光线，降低水体透明度，对水生生物和微生物造成影响，不利于水体自净同时造成视觉上的污染，给环境构成较大破坏。由于染料品种的变化以及化学浆料的大量使用,使废水含难生物降解的有机物,可生化性差，因此,印染废水是一种较难处理的工业废水。我国染料行业废水治理技术已取得一批实用技术，但总体上没有实质性的突破，处理工艺也不尽相同，有单独生化处理的，有单独物化处理的，有生化过程有只采用氧化工艺的，物化过程有气浮、活性炭吸附、氧化脱色、混凝沉淀等等，种类繁多。现实生产中，大部分处理工艺都存在一定的不足，进行印染废水治理的研究与技术开发，仍然是具有积极现实意义的重要课题。本文介绍了染料废水的来源及特点，探讨该废水处理的主要方法。

With the textile industry to flourish, each year, printing and dyeing wastewater emissions in China more than 1700 million cubic meters. Dye wastewater can absorb light, reducing the transparency of the water body, to aquatic organisms and micro-organisms affect the body of water is not conducive to self-purification at the same time causing visual pollution, greater damage to the environment. Species as a result of changes in dye and chemical slurry use of large quantities of wastewater containing biodegradable organic matter difficult, poor biodegradability, therefore, printing and dyeing wastewater is a difficult industry. China's dye industry wastewater treatment technology has achieved a number of practical techniques, but in general there are no substantive breakthroughs are not the same process, the biological treatment alone, with physico-chemical treatment alone, with only the use of chemical and biological oxidation process technology, physical and chemical flotation p
