摘要
木质素是广泛存在于地球上各种植物中的天然大分子有机物,造纸废水中含有大量木质素,严重污染环境。研究开发木质素应用技术,是消除其作为废弃物对环境造成危害和弥补矿储资源日渐匮乏实现可持续发展的有效途径。木质素改性技术的发展,使其可利用性不断增强,在环境污染防治中也得到了应用,木质素在肥料与农药的缓/控释、水处理絮凝剂、土壤促渗削减雨水径流控制非点源污染等技术研究成果,成为木质素资源再利用的技术基础,对消除木质素排放造成的环境污染,实现相关领域环境污染治理与控制,开发可再生资源都具有重要意义和价值,发展前景广阔。在着重介绍木质素及其改性物在环境污染防治中应用研究进展的基础上,预测了木质素改性研究的方向。
Lignin is one kind of natural macromolecule material which widely exists in various plants on the Earth.Wastewater from a paper making contains a lot of lignin that may result in heavy pollution on our environment.Therefore,reutilization of lignin is an effective way in reducing the pollution of lignin as a waste and it is an efficacious remedy of shrink of mine resource according to sustainable development philosophy.Technologies of modification for the lignin make the value of lignin boost up and such those techniques have already been used in prevention from environment pollution in resent years.The most interesting techniques include those such as the slow or controlled release of fertilizers and pesticides,water treatment flocculation agents,soil enhancement agents of rain runoff infiltration in control of non-point-source pollution.Those technologies will be the technical base of reuse of lignin,and they will reduce pollution of the drainage and in controlling environment pollution.There is an unusual significance of reused resource.In addition,there will be very broad applicable prospect in the future.This article emphasizes that the utilization of lignin and its modified analogs in prevention of environment from pollution and has made a scientific prediction on the research of modified lignin.
