制浆漂白废水的环境影响及控制
ENVIRONMENTAL IMPACT OF PULP BLEACHING EFFLUENTS AND ITS CONTROL
-
摘要: 本文对有关制浆造纸工业漂白废水对环境的影响及其污染控制研究现状进行综述。制浆造纸工业废水是重要工业污染源,使用氯漂的制浆漂白废水全有毒、致突变、难降解的有机氯化物。对该废水的环境影响及污染控制的研究目前集中于木浆多段漂。我国制浆工业以非木材为主,工厂小、技术落后,多采用次氯酸盐单段漂。研究草浆漂白废液之组成、环境危害、致毒因素,为治理提供依据,是我国环境化学工作者今后的一项重要课题。Abstract: The present status of research on environmental impact of pulp bleachingeffluents and its control is reviewed. The greatest part of these studies has so far involved the wood pulping industry. The research concerning pollution control of nonwood pulp bleaching effluents is important work for Chinese environmental chemists since nonwood fibers are the major raw materials for pulp manufacture. Some studies which should be carried out in the coming days in the field are propcsed.
