印染废水的成分主要有染料、浆料、助剂、酸碱、纤维杂质及无机盐等,具有成分复杂、浓度和色度高、难降解、抗氧化、抗生物氧化性等特点[1-7]。印染行业用水量大、回用率低、水资源浪费严重,若对印染废水进行深度处理并回用,不仅可节约大量新鲜水,还能减少废水排放量,对促进行业可持续发展具有重要意义。 The components of printing and dyeing wastewater mainly include dyes, size, auxiliaries, acid and alkali, fiber impurities, inorganic salts, etc. it has the characteristics of complex components, high concentration and chroma, difficult degradation, oxidation resistance, biological oxidation resistance, etc. Printing and dyeing industry has large water consumption, low recycling rate and serious waste of water resources. If the printing and dyeing wastewater is treated and reused in depth, not only a lot of fresh water can be saved, but also the discharge of wastewater can be reduced, which is of great significance to promote the sustainable development of the industry. 近年来,混凝剂被广泛用于印染废水处理中。季铵型阳离子脱色剂是一种新型高效脱色剂,用于去除工业废水中的有害成分,使之达到排放或回用目的,是工业废水处理的重要方法之一。硅藻土由于具有独特的硅藻壳体结构、强吸附性、大比表面积、高孔隙度等优点,对污水有极好的净化效果。 In recent years, coagulants have been widely used in the treatment of printing and dyeing wastewater. Quaternary ammonium type cationic decolorizer is a new type of decolorizer with high efficiency. It is one of the important methods of industrial wastewater treatment to remove harmful components from industrial wastewater and make it discharge or reuse. Diatomite has the advantages of unique diatom shell structure, strong adsorption, large specific surface area, high porosity and so on. It has excellent purification effect on sewage. |
