摘　　要：用人工配制高浓度有机废水分别研究了Ｃｌ－和ＳＯ２－４对厌氧生物废水处理的抑制作用和抑制阈值．在全混流厌氧恒化器和上流式厌氧污泥床（ＵＡＳＢ）反应器中分别得到了对厌氧消化基本无抑制作用（全混流恒化器：Ｃｌ－＜４．５ｇ／Ｌ，ＳＯ２－４＜１．８ｇ／Ｌ；ＵＡＳＢ：Ｃｌ－＜７．２ｇ／Ｌ，ＳＯ２－４＜３．０ｇ／Ｌ）；轻度抑制（全混流恒化器：Ｃｌ－＝４．５～６．０ｇ／Ｌ，ＳＯ２－４＝１．８～３．３ｇ／Ｌ；ＵＡＳＢ：Ｃｌ－＝７．２～８．２ｇ／Ｌ，ＳＯ２－４＝３．０～４．１ｇ／Ｌ）；中度抑制（全混流恒化器：Ｃｌ－＝６．０～１３．８ｇ／Ｌ，ＳＯ２－４＝３．３～６．５ｇ／Ｌ；ＵＡＳＢ：Ｃｌ－＝８．２～１０．０ｇ／Ｌ，ＳＯ２－４＝４．１～６．０ｇ／Ｌ）和重度抑制（全混流恒化器：Ｃｌ－＞１３．８ｇ／Ｌ，ＳＯ２－４＞６．５ｇ／Ｌ；ＵＡＳＢ：Ｃｌ－＞１０．０ｇ／Ｌ，ＳＯ２－４＞６．０ｇ／Ｌ）的不同Ｃｌ－和ＳＯ２－４浓度范围．The inhibition of Cl - and SO 2- 4 to the anaerobic wastewater treatment was investigated using synthetic high concentration organic wastewater as a substrate. The different Cl - and SO 2- 4 concentration range of non inhibition(CSR:Cl<4.5 g/L, SO 2- 4<1.8 g/L; UASB:Cl -<7.2 g/L, SO 2- 4<3.0 g/L), slight inhibition (CSR:Cl -=4.5￣6.0 g/L, SO 2- 4=1.8￣3.3 g/L; UASB:Cl -=7.2￣8.2 g/L, SO 2- 4= 3.0 ￣4.1 g/L), medium inhibition (CSR:Cl -=6.0￣13.8 g/L, SO 2- 4=3.3￣6.5 g/L; UASB:Cl -=8.2￣10.0 g/L, SO 2- 4=4.1￣6.0 g/L) and serious inhibition (CSR:Cl ->13.8 g/L,SO 2- 4>6.5 g/L; UASB:Cl ->10.0 g/L, SO 2- 4>6.0 g/L) to anaerobic digestion were obtained in complete stired reactor(CSR) and UASB reactor.
