摘　　要：磺胺废水因毒性有机物浓度高，酸性极强而成为制药厂废水处理的棘手难题。本文通过产甲烷毒性试验的测定，探讨磺胺废水对产甲烷细菌毒害的机理，确认其毒性在低浓度时属于代谢性毒性，而在高浓度时属于杀菌性毒素。同时获得了一组产甲烷活性随不同稀释比变化的曲线，证明该废水在稀释比不超过 1/7时可以进行厌氧生物处理。Sulfanilamide products wastewater is very difficult to be treated for its high concentration of toxic organic matter, Cl- and SO42-. The methanogenic toxicity experiments are conducted to determine its toxic mechanism and the feasibility of anaerobic bio-treatment. The results show that sulfanilamide products wastewater belongs to metabolic toxin at lower concentrations while bactericidal toxin at higher concentrations. In addition, methanogenic activity curves with different dilution ratios are obtained, which illustrate that the wastewater can be anaerobic bio-treated when the dilution ratios are not greater than 1/7.
