摘　　要：工业的快速发展使得高浓度化工废水污染问题日益严峻,常规处理方法难度较大且成本高昂。两相厌氧法利用相分离手段划分产酸相还原过程和产甲烷过程,在处理高浓度化工废水以及能源回收利用方面具备独特优势。因此,在分析两相厌氧法动力学原理及菌群生理生化特征的基础上,使用基于改进Markov的化工废水浓度预测算法明确化工废水污染浓度,从而发现水质恶化机理。实验结果证明此种处理方法可以有效实现化工废水的无害化、资源化处理,具备良好的应用前景。With the rapid development of industry,the problem of high concentration chemical wastewater pollution becomes more and more serious.The conventional treatment methods are difficult and costly.Two-phase anaerobic process can be divided into acid-producing reduction process and methane-producing process.It has unique advantages in high concentration chemical wastewater treatment and energy recovery and utilization.Therefore,on the basis of analyzing the kinetic principle of two-phase anaerobic method and the physiological and biochemical characteristics of bacterial flora,the chemical wastewater concentration prediction algorithm based on improved Markov was used to determine the pollution concentration of chemical wastewater,so as to find the mechanism of water quality deterioration.The experimental results show that this treatment method can effectively realize harmless and resource treatment of chemical wastewater,and has a good application prospect.
