MBRM reaction model based on microalgae-bacteria symbiotic wastewater treatment technology
The microbial metabolism system of microalgae-bacteria symbionts can be used for wastewater treatment,which can rapidly and synchronously remove carbon,nitrogen,phosphorus and other pollutants that were easy to cause eutrophication of water bodies,and the stable biological system has broad application prospects.The mathematical model can be used to de-scribe the treatment process abstractly,explore the change rule,and summarize the appropriate parameter optimization strate-gy,which was of great significance for the subsequent effect strengthening and expanding application of the process.Although there were many mathematical models based on biochemical treatment as the basis,in view of the complexity of microalgae-bac-teria symbiosis system,the mathematical modeling of the system was still in the exploratory stage.Based on the experimental process of microalgae-bacteria symbiosis treatment technology in livestock and poultry breeding wastewater treatment,this study developed a MBRM mathematical model to simulate the treatment effect of microorganisms in the reactor on pollutants in wastewater,the change of microbial growth status and the impact of environmental factors.The model was verified and calibra-ted through 30 days continuous operation experiment,it was verified that the model could accurately simulate the relevant water quality changes and microbial growth in the microbial treatment process according to the operation parameters of the reactor and the quality of the incoming and outgoing water.
