摘要

Upflow anaerobic sludge blanket(UASB)reactors were used in this study to evaluate the feasibility of the sulphate- reducing, anaerobic high-rate process to treat metal- and sulphate-containing mining wastewater (MWW). Four simultaneous reactors, inoculated with different inocula(mesophilic granular sludge from two UASB reactors, one treating sugar refinery wastewater ad the other board mill wastewater) and operated with different loadings, were for 95 days fed with synthetic feed consisting of glucose and sulphate. In all reactors, 23-72/100 of sulphate and 12-93/100 of COD were removed.
