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-<4.5 g/L, (SO2-4)<1.8 g/L;UASB:Cl-<7.2 g/L,(SO2-4)<3.0 g/L);轻度抑制(全混流恒化器:Cl-=4.5~6.0 g/L, (SO2-4)=1.8~3.3 g/L;UASB:Cl-=7.2~8.2 g/L, (SO2-4)=3.0~4.1 g/L);中度抑制(全混流恒化器:Cl-=6.0~13.8 g/L, (SO2-4)=3.3~6.5 g/L;UASB:Cl-=8.2~10.0 g/L, (SO2-4)=4.1~6.0 g/L)和重度抑制(全混流恒化器:Cl->13.8 g/L, (SO2-4)>6.5 g/L;UASB:Cl->10.0 g/L, (SO2-4)>6.0 g/L)的不同Cl-和(SO2-4)浓度范围.
用人工配製高濃度有機廢水分彆研究瞭Cl-和(SO2-4)對厭氧生物廢水處理的抑製作用和抑製閾值.在全混流厭氧恆化器和上流式厭氧汙泥床(UASB)反應器中分彆得到瞭對厭氧消化基本無抑製作用(全混流恆化器:Cl-<4.5 g/L, (SO2-4)<1.8 g/L;UASB:Cl-<7.2 g/L,(SO2-4)<3.0 g/L);輕度抑製(全混流恆化器:Cl-=4.5~6.0 g/L, (SO2-4)=1.8~3.3 g/L;UASB:Cl-=7.2~8.2 g/L, (SO2-4)=3.0~4.1 g/L);中度抑製(全混流恆化器:Cl-=6.0~13.8 g/L, (SO2-4)=3.3~6.5 g/L;UASB:Cl-=8.2~10.0 g/L, (SO2-4)=4.1~6.0 g/L)和重度抑製(全混流恆化器:Cl->13.8 g/L, (SO2-4)>6.5 g/L;UASB:Cl->10.0 g/L, (SO2-4)>6.0 g/L)的不同Cl-和(SO2-4)濃度範圍.
