摘　　要：采用单宁废水驯化厌氧折流板反应器(ABR),然后用驯化后的ABR预处理栲胶废水,研究ABR反应器对BA浅色栲胶和荆树皮栲胶的处理效果。结果表明:驯化过程中,VFA、pH以及碱度都保持在一个比较稳定的水平。驯化结束后,污泥产甲烷活性更高。驯化后的ABR反应器对栲胶废水有较高的去除作用,COD为2 000mg/L的BA浅色栲胶废水和荆树皮栲胶废水的去除率分别达80%以上和70%以上,表明荆树皮栲胶废水比BA浅色栲胶废水更难降解。Tanning extracts were domesticated by tannin with anaerobic baffled reactor （ABR）and the tannin waste water was pre - treated. It shows that the values of VFA, pH and alkalinity are kept at a relatively stable level during the process of domesti- cation. When domestication ended, ABR reactor has higher sludge activity of producing methane. It has higher removal rate for tanning extracts when ABR was domesticated by tannin. When COD of wastewater, which was simulated with BA light color vege- table wastewater and the thorns bark tannin extracts, is 2000 mg/L, removal rate of COD is more than 80% and 70%, respective- ly. It shows that the thorns bark tannin extracts wastewater is more difficult for degradation than BA light color tanning extracts.
