摘要
随着石油化工、塑料、合成纤维、焦化等工业的迅速发展,排向环境的各类含酚废水也相应增加。由于酚的毒性大,并具有致癌、致畸、致突变的潜在毒性,近年来引起了广大研究人员的重视。鉴于清除或降解水中的酚类污染物,不仅涉及水生生物及陆生植物的生长繁殖,更涉及到人类及陆生动物的食品饮水安全,因此,研究含酚废水的高效处理技术,对保护环境具有极为重要的意义。本文在介绍了含酚废水的主要来源及其危害之后,就近年来含酚废水处理新技术-光催化技术、超声氧化技术、超临界水氧化技术等的发展现状进行了阐迷,并提出了当前含酚废水处理技术的发展前景及方向。
With the rapid development of chemical industries such as petroleum chemical engineering, plastics, synthetic fabric, coking and so on, more and more phenol - containing wastewater was discharged to our environment. Because phenolic contaminants take on great toxicity which could cause cancer, abnormality and sudden change, many researchers attach importance to them. Eliminating or degrading phenolic contaminants in water was involved not only with the bioplastic and propagation of hydrephily biology but also with drinking safety of mankind and terraneous animals. So the research of a kind of high efficient treatment technology to treat phenol wastewater is of great importance to protect our environment. This paper introduced the harm of phenol - containing wastewater and source of it, then elaborates the development of some new techniques for treatment of phenol - containing wastewater such as photo catalysis, ultra sonic oxidation and super critical water oxidation, and suggested the prospect and direction of them.
