摘要
本文所做的机理分析和试验研究表明,在COD>3000mg/L,SO_4^(2-)<5100mg/L,COD/SO_4^(2-)>4的条件下,硫酸盐对高浓度有机废水厌氧处理的影响主要是使发酵过程pH 值不断上升,为了防止pH 高出产甲烷菌生长的最佳范围,需适当降低进水的pH 值。
Theoretical analysis and experimental study show that,on the condi-tion of COD>3000mg/L,SO_4^(2-)<5100mg/L,COD/SO_4^(2-)>4,the main effectof sulphate on anaerobic digestion of high strength organic wastewateris to increase the pH of the process continuously.In order to prevent pHfrom exceeding the pH ronge for methane producing bacteria growth,the influent pH must be decreased properly.
