The Wastewater Reuse Scheme In North-center Section In Hexi In Taiyuan And Process Design Of Phosphorus And Nitrogen Removal

The thesis was about wastewater reuse in north-centre section wastewater plant in hexi,which elaborated selection and design on this scheme and the process of phosphorus and nitrogen removal was design accordingly.The main achievements were as follows:One: the secondary biological strengthen treatment process and filtering process were used as recycle and reuse process,which was with a lot of advantages such as advanced technology,feasibility on the economy and better social and economic efficiency,meanwhile, the process had provided regular reference value for the wastewater reuse and supply of the same wastewater plant.Two: The effect of A2/O process on phosphorus and nitrogen removal was striking, this process fitted in the new construction plant and the revision and expansion of the old wastewater treatment plant.
