响应面法优化藻菌污水处理系统曝气条件研究
Study on optimization of aeration conditions in algal-bacterial wastewater treatment system using response surface method
摘要
Abstract
The wastewater treatment capacity of algal-bacterial symbiotic systems can be further improved by optimizing the process parameters during advanced wastewater treatment using the response surface method.This study employed the response surface method(RSM)to optimize the aeration volume and CO2 volume fraction in algal-bacterial symbiotic system,analyzing its impact on the removal rates of nutrients to achieve optimal removal efficiency.The results indicate that the removal rates of Total Nitrogen(TN)and Ammonium Nitrogen(NH3-N)are significantly influenced by the aeration volume,whereas the removal rates of Total Phosphorus(TP)and Chemical Oxygen Demand(COD)are more susceptible to changes in CO2 volume fraction.The optimal aeration conditions predicted by the response surface method were an aeration volume of 0.639 L/min and a CO2 volume fraction of 3.849%.Under these conditions,the removal rates of TN,TP,NH3-N and COD reached their were maximum values within 2 days,achieving 70.040%,72.925%,100%and 83.612%respectively.关键词
