摘　　要：在养鱼产业中,高张力废水的排出处理,在全世界都是一个很热门的话题。生物处理法是处理废水的最好方法。厌氧固定床和流化床反应器(AFB)、升流式厌氧污泥床反应器(UASB)可以除去80～90%的有机物,同时产生生物气。需氧过程如活性淤泥,旋转的生物接触器,渗漉器,曝气生物滤池也可以除去有机物。对污水先进行厌氧消化,再进行需氧过程处理是最适合的方法。The breatment of high-strength wastewater from fish-processing industry are of great concern world-wide. Biological treatment is the best option for such a wastewater. Anaerobic processessuch as upflow anaerobi sludge blanket (UASB) reactor, anaerobic filter (AF) and anaerobic fluidlized bed (AFB) reactor can achieve high (80-90%) organics removal and produce blogs.Aerobic processes such as activated sludge, rotatin biological contactor, trickling filter and lagoons are also suitable for organics removal. Anaerobic digestion followed by an aerobic process is an optimal process option for fishprocessing wastewate treatment.
