Preface The BIOTOL series of texts are designed to provide a self-study resource concerning the principles, practices and applications of biotechnology. This text is designed to explain how biotechnology may be applied to solve problems encountered in the production and use of organic chemicals in a wide range of business sectors

1、掌握:病毒的结构,化学组成与作用。 2、熟悉:病毒增殖的方式;病毒复制的五个阶段;病毒对理化因素的抵抗力。 3、了解:病毒的大小与形态;病毒生物合成的基本步骤丶病毒复制的异常现象

固体废物是指被丢弃的固体和泥状物质,包括从废水、废气中分离出来的固 体颗粒,简称废物。被丢弃的非水液体,如废变压器油等由于无法归入废水、废 气类,固习惯上归在废物类。 固体废物主要来源于人类的生产和消费活动。它的分类方法很多:按化学性 质可分为有机废物和无机废物;按形状可分为固体和泥状的;按它的危害状况可 分为有害废物和一般废物;按来源可分为矿业固体废物、工业固体废物、城市垃 圾(包括下水道污泥)、农业废物和放射性固体废物等。在固体废物中对环境影响 最大的是工业有害固体废物和城市垃圾
