Using biodegradable polymers as carbon source for nitrate removal in marine re-circulated aquaculture systems
以可生物降解聚合物为碳源去除海水闭合循环养殖系统中的硝酸盐

To overcome the problem of the low C/N ratio in denitrification process of wastewater treatment for marine racirculated aquaculture systems,PBS in the form of biodegradable polymers pellets(BDPs) was investi-gated as carbon source and bioflm carrier to remove nitrate from saline water in a packed-bed laboratory reactor.The experimental results indicated that nitrate was effectively removed within such a reactor.Low DOC concentra-tion in the effluent and increase of the effluent pH were observed in this proc...
