富磷污泥的处理与水体富营养化的预防

Dealing of mud and prevention of wave eutrophia

城市污水和工业废水中含有的氮、磷等植物性营养物质是导致湖泊等缓流水体富营养化的主要原因。通过绝氧———好氧活性污泥法去除 Ｂ Ｏ Ｄ 的同时也去除引起水体富营养化的盐———磷，以抑制水生植物繁衍，达到防止水体富营养化的目的。

Hydrogen and phosphorus and other eutrophia materials contained in urban and industrial waste water. Are main causes that cause wave eutrophia. BOD in mud can be wiped out by non-oxygen-oxygen-active mud. In the meanwhile phosphorus, a kind of salt that cause wave eutrophia can be also wiped out in order to restrain production of water plants and received good results in prevention of wave eutrophia.
