Hypersaline organic wastewater such as petrol, chemical and dyeing wastewater, withcomplicated organic composition and high salinity (ions such as Cl~-, Ca~(2+), and Na~+), is difficultto treat by conventional biochemical processes. The diosgenin wastewater was a representative ofhypersaline wastewaters with high chloride ions (about above 10000mg/L) and organic pollutants(COD about above 20000 mg/L). To solve the problem of inhibitory effect of high salinity ontraditional biological wastewater tr...
