摘　　要：用水解酸化工艺预处理齐鲁石化氯碱厂所排放的氯碱废水，试验结果表明：水解酸化反应器中COD去除率在20％-34％之间，挥发酸（VFA）质量浓度呈逐步升高的趋势，ρ（BOD）／ρ（COD）的出水值比进水值平均提高了27％，改善了废水的可生化性，多种复杂有机污染物可得到有效降解，为后继的好氧处理提供了有利条件。The process of hydrolysis acidification was used in the pretreatment of chloro-alkali wastewatcr discharged from Qilu petrochemical chloro-alkali factory. The experiment showed that the removal rate of COD was between 20 % - 34 %, while the content of volatile acid （VFA） increased gradually. The concentration ratio of BOD and COD of water discharged was 27 % higher than that in the inflow. Many complex organic contaminants can be biodegraded, and the biodegradability of wastewater is improved distinctly, which facilitates the further aerobic treatment of wastewater.
