两种棉浆黑液处理工艺的研究

Study on two treatment processes for cotton pulp black liquor

棉浆黑液具有色度大、污染物浓度高、难降解等特性,成为污水处理的一个难点。以阿拉尔某棉浆场黑液为研究对象,分别采用紫外光+双氧水法和铁屑微电解法对棉浆黑液进行净化处理,并对2种工艺进行了比较分析。研究结果显示,2种不同处理工艺对棉浆黑液都具有良好的处理效果,比较而言,铁屑微电解法处理效果更佳。该研究成果不仅可为新疆棉浆厂、化纤厂等企业难降解污水的处理提供理论与技术支持,而且对保护新疆水资源和水生态环境具有积极作用。

Cotton pulp black liquor has characters of high chroma,high concentration of pollutants and difficult to degrade,and becomes one of the difficulties in sewage treatment.In this paper,the black waste liquor from a cotton pulp factory in Alar city is treated by UV/H2 O2 method and iron chips micro-electrolysis method respectively,and the two methods are compared and analyzed. The results show that both the two methods have good effect on treating with the cotton pulp black liquor,moreover,the iron chips micro-electrolysis method does better.The research results will not only provide an important theoretical basis and technical support for the treatment of wastewater that is difficult to degrade from cotton pulp factories,chemical fiber plants and so on,but also have a positive effect on the protection of water resources and aquatic environment in Xinjiang.
