Description
技术领域technical field
本实用新型属于净化装置技术领域，特别涉及一种强吸附反渗透协同作用的印染废水净化装置。The utility model belongs to the technical field of purification devices, in particular to a printing and dyeing wastewater purification device with strong adsorption and reverse osmosis synergy.
背景技术Background technique
纺织工业是我国国民经济的传统支柱产业和重要的民生产业，也是国际竞争优势明显的产业。为了满足人们对纺织织物不同色彩的需要，需要对其进行染色，但在染色时，特别是在进行深浓色染色时，由于上染率不够高，部分染料不能固着在织物上，造成了原料的浪费，进而导致了大量有色废水的产生。纺织印染废水是我国工业系统中重点污染源之一，据国家环保总局统计， 印染行业排放的印染废水总量位于全国各工业部门排放总量的第五位。印染废水作为环境重要污染源的特点，首先是污染量大，对环境的污染更为严重，2004年全行业排水量13.6亿立方米，而其污染物排放总量以COD计则位于各工业部门第六位；第二是作为环境污染物的印染种类多、 结构复杂、印染废水色度大、有机物浓度高、组分复杂及难生物降解物质多，属于难处理的工业废水；第三是多数印染为有毒难降解有机物，化学稳定性强，具有致癌、致畸和致突变的“三致”作用。废水中残存的印染组分即使浓度很低，排入水体也会造成水体透光率降低，导致水体生态系统的破坏。 因此，对印染废水进行有效的处理成为重要的课题。The textile industry is a traditional pillar industry of my country's national economy and an important livelihood industry, as well as an industry with obvious international competitive advantages. In order to meet people's needs for different colors of textile fabrics, it is necessary to dye them. However, when dyeing, especially when dyeing deep and thick colors, due to the insufficient dyeing rate, some dyes cannot be fixed on the fabric, resulting in raw materials. waste, which in turn leads to the generation of a large amount of colored wastewater. Textile printing and dyeing wastewater is one of the key pollution sources in my country's industrial system. According to the statistics of the State Environmental Protection Administration, the total amount of printing and dyeing wastewater discharged by the printing and dyeing industry ranks fifth in the total discharge of all industrial sectors in the country. Printing and dyeing wastewater, as an important environmental pollution source, has the characteristics of large amount of pollution and more serious environmental pollution. In 2004, the industry-wide drainage volume was 1.36 billion cubic meters, and its total pollutant discharge in terms of COD ranked sixth among all industrial sectors. The second is that as environmental pollutants, printing and dyeing has many types, complex structures, high chroma, high concentration of organic matter, complex components, and many refractory biodegradable substances, which are difficult to treat industrial wastewater; Toxic and refractory organic matter with strong chemical stability and the "three causes" of carcinogenicity, teratogenicity and mutagenicity. Even if the concentration of printing and dyeing components remaining in the wastewater is very low, if discharged into the water body, the light transmittance of the water body will decrease, resulting in the destruction of the water body ecosystem. Therefore, effective treatment of printing and dyeing wastewater has become an important issue.
印染废水的水质具有污染物浓度高、种类多、含有毒有害成分及色度高等特点，目前国内外在这类废水处理中常用的处理方法主要有物理法、化学法、生物法等多种处理技术，但采用单一的处理方法很难彻底地解决印染废水的污染问题，集合使用两种或者多种方法则可以更好更快地达到治理重金属废水的目的，所以，在将来印染废水处理的领域，通过各种处理方法的复合应用预计会收到较好的效果。The water quality of printing and dyeing wastewater has the characteristics of high pollutant concentration, many types, toxic and harmful components, and high chroma. At present, the commonly used treatment methods in this type of wastewater treatment at home and abroad mainly include physical methods, chemical methods, biological methods, etc. However, it is difficult to completely solve the pollution problem of printing and dyeing wastewater by using a single treatment method. The combination of two or more methods can achieve the purpose of treating heavy metal wastewater better and faster. Therefore, in the field of printing and dyeing wastewater treatment in the future , the composite application of various treatment methods is expected to receive better results.
