土壤净化功能的原理及其利用

本文通过对土地处理系统的剖析，从土壤去除有机物，悬浮物，氮，磷，汞量重金属，病原散生物，污染空气。以及对酸性沉降物的缓冲等诸方面，讨论了土壤净化功能的原理，概括了土壤净化过程，既包括物理的，化学的和生物的作用，又包括物理化学，生物化学的作用，为更好地研究，利用和管理土地处理系统，充分发挥土壤的净化功能提供研究的方向。

The Pricinples of Soil Purification and Its Utilization

The pricinples of soil purification, which include the cleaning of organism matter,suspended solis,nitrogen,phospho-rous, trace heavy metals,pathogenic metals. pathogenic microorganisms, harmful gases by soil-plant system, and the buffer of acidic pricipitation by soilwere discussed by analysing the land treatment system in this paper. These pricmples consist of either simple physical. chemical.biolgical process. or complex physical-chemical and biochemical processes It would lay theoretical basis for designing, running. and using of the land treatment system.
