High salinity wastewater including diosgenin wastewater, oil field wastewater and effluent from direct use of seawater is difficult to treat due to seriously restriction of organisms growth by high salt content. 高盐度有机废水是一种难处理的废水,如皂素废水、油开采废水以及海水直接利用后排放出的废水,主要是因为高含盐量对微生物的生长有很强的抑制作用,严重抑制了生物法在高盐度废水处理中的应用。
