    摘要:

    随着工业技术的快速发展,工业废水产量也与日俱增,其中,焦化废水排放量大、组成成分复杂、影响程度深,所引发的环境污染尤为突出,一系列排放标准规定日趋严格,焦化废水的处理迫在眉睫。为尽快实现企业废水"零排放"政策要求,多种新型处理技术应运而生,治理效果和应用范围明显提高。通过综述现有焦化废水处理技术的特征与局限性,发现焦化废水处理方法多集中于生物处理技术和高级氧化法,而二者现常用技术在实际运行中仍存在处理效果不佳、运行成本过高等问题与挑战。但是,生物降解和高级氧化耦合处理技术前景广阔,不仅能提高处理效率,还能开拓多维探究领域,大量研究表明其对于难降解污染废水处理具有较大可行性。展望多工艺联用在焦化废水处理中的实用性,为深化焦化废水处理研究提供新的思路。

    Abstract:

    With the rapid development of industrial technology in China, the output of industrial wastewater is also increasing day by day, in which coking wastewater discharge is large, composition is complex, influence degree is deep, the environmental pollution caused by it is especially prominent, a series of discharge standards are becoming more and more strict, and the treatment of coking wastewater is imminent. In order to realize the policy requirement of "zero discharge" of enterprise wastewater as soon as possible, various new treatment technologies emerge as the times require, and the treatment effect and application scope are obviously improved. In this paper, the characteristics and limitations of the existing coking wastewater treatment technology are reviewed. At present, the coking wastewater treatment methods are mostly focused on biological treatment technology and advanced oxidation method, but there are still some problems and challenges in the actual operation of the two commonly used technologies, such as poor treatment effect and high operating cost. However, the technology of biodegradation and advanced oxidation coupling treatment has a broad prospect, which not only improves the treatment efficiency, but also opens up the field of multi-dimensional exploration. A large number of studies have shown that it has great feasibility for the treatment of refractory and polluted wastewater.
