【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。更多还原

【Abstract】 The process of hydrolysis acidification was used in the pretreatment of chloro-alkali wastewater 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.更多还原
