【摘要】 微生物法和微生物生态法作为生物治理方案的两大类型，已日益受到环保工作者的重视。这两种类型的治理方法各有特点，各有利弊。如何选择使用？主要取决于污染场所中污染形成的时间长短、污染程度、污染物浓度、污染物中是否含有污水、是否需要快速治理等。应明确指出的是，采用生物治理法虽可在多种情况下大大降低污染物的浓度，但从长远来看，还不能单纯依靠降低污染物的排放浓度，而是应从低浓度污染物对人和环境产生的长期影响着眼，制定出一套治理标准，这样才能准确评价生物治理技术在环境保护中所起的真正作用。更多还原

【Abstract】 Microbial method and microbiological ecological method known as two main types of biological control plans have been highly valued by the relevant technical personnel day by day．The control methods of these two types have their respective characteristics，advantages and disadvantages．How to select and utilize them？It mainly depends upon the length of time of pollution caused in polluted area，degree of pollution，concentration of pollutants，whether to need immediate control，whether to have sewagein pollutants and so on．It should be made clear and definite that the adoption of biological control method can under most conditions greatly reduce the concentration of pollutants,but in the long run we cannot merely depend on reducing the effluent concentration of pollutants and，what is more，should clarify the long-term influence of low concentration pollutants upon people and environment and draw up a set of standards so as to be able to accurately evaluate the true action of biological control technology on environmental protection．更多还原
