深海锰结核作生物固定化载体处理染料废水

用深海锰结核作生物固定化载体,在气升式反应器内进行了对比实验.结果表明:结核作固定化载体处理废水,可有效地降低废水中的化学耗氧量(COD)、生物耗氧量(BOD)、固体悬浮物(SS)、色度等,并可打开难降解的苯环.固定化微生物脱色机理是载体吸附和细菌降解双重作用.处理后的污水可作为J13菌的有效营养和碳源,作为微生物浸出深海锰结核中有价金属的培养基.固定化微生物在染料废水处理中有实用价值.

Manganese Nodules as Bio-immobilized Carrier to Degradation Dye Wastewater

Using manganese nodules as immobilized carrier, in an air-lift loop reactor the investigation on comparing immobilized carrier to disposal dye wastewater with non immobilized carrier was carried out. It is proved that with nodules as immobilized carrier to degradation organisms in dye wastewater, are effecitivity the color depriving character of immobilized microbe rely on adsorption and bio-degrading, biological oxygen demand(BOD), chemical oxygen demand(COD), suspended solid(SS) and color degree can be largely re- moved, and the benzene can be destroyed. The treated water can be applied to culturing microbe. It's Practi- cable to dispose dye wastewater with immobilized microbe.
