城镇生活污水、含氮的工业废水和农田氮肥是水环境的主要氮污染源。影响水环境中氮污染的主要因素是含氮污水的排放性状、纳污水体的环境容量以及人为与自然条件下氮素的物理、化学的转化作用。
Domestic waste water from towns and villages, nitrogenous industrial waste water and agricultural nitrogen manure are the mainnitrogen pollution sources. The chief facors of nitrogen pollution which influences the waer enviroment are the discharging condition ofnitrogenous waste waer, the envirorunental capacity of pollution recipient of waer and the physical and chemical transformation of nitrogenelement under man-mads and natural conditions.
