Water self-purification


水体自净  water self-purification

指水体受到污染后，由于物理、化学、生物因素的作用，使污染物浓度和毒性逐渐降低，经过一段时间，恢复到受污染以前状态的自然过程。


Self-purification occurs naturally in water bodies by physical, chemical and biochemical processes to reduce pollutants’concentrations and toxicities.


physical purification 物理自净

  混合、稀释、扩散、挥发、沉淀等

chemical purification 化学自净

  氧化、还原、中和、吸附、凝聚等

biochemical purification 生物化学自净

  吸收、降解等
