摘要
传统制浆造纸工业中许多工艺过程是化学过程。在化学过程中往往伴随产生一些高BOD、COD、SS负荷的废水,其中一些废水还含有高毒性和强致癌性的物质,以致环境受到极严重的污染。随着生物技术的发展,自七十年代初利用生物科学和技术改革传统制浆造纸工艺在国际范围迅速展开,短短二十多年取得了长足的进步,在研究植物纤维原料各成分的生物转化( 包括微生物及所产生的酶) 规律的基础上,针对浆纸工业传统工艺所存在的问题,利用生物途径来解决,并已在生物漂白、解决树脂障碍以及废纸酶法脱墨等方面进入了实际应用。本文对上述的最新进展进行扼要的综述。
Conventional pulping and bleaching are chemical processes and the effluents with high loads of BOD,COD and SS are produced during these processes.The effluent contained strong toxic and mutagenic substances could make serious pollution environmentally.Since 1970's,biotechnology in the pulp and paper industry has been rapidly developed worldwide and significant progresses have been made based on the investigations of lignocellulose bioconversion.Biobleaching,pitch control by biotechnology and biodeinking have been put into practice.Recent advances of biotechnology in the pulp and paper industry are reviewed in the present paper.
