微界面高级氧化处理煤化工废水的研究
Research on advanced oxidation treatment of coal chemical wastewater using microinterfaces
摘要
Abstract
The deep treatment of various organic pollutants contained in coal chemical wastewater and the improvement of its reuse rate have important ecological and economic significance.However,some pollutants have high concentrations and traditional wastewater biological treatment processes cannot completely remove them.Failing to meet increasingly stringent wastewater discharge standards.This article constructs a structure-activity regulation mathematical model for the advanced oxidation reaction system of coal chemical wastewater based on a microinterface enhanced reactor,clarifying the strengthening mechanism and efficiency of microinterface enhanced technology on ozone advanced oxidation.The results showed that under the same conditions,the bubble size decreased from 10.0 mm to 0.1 mm,and the COD removal rate of wastewater increased from 70.02％to 90.02％.At the same gas volume,when the COD removal rate reaches 70％,the microinterface reactor can increase the wastewater treatment capacity by 66.50％compared to the ordinary bubble reactor.Provide strong reference for the scaling up and design of advanced oxidation treatment of coal chemical wastewater at microinterfaces.关键词
