Abstract

This paper takes cyclic economy as research background, adopting diatomite to enforce A2 /O process and to make treatment study, using A2 /O process testing equipment to simulate the running conditions of A2/O process in wastewater treatment plant, and adjusting the index parameters in A2/O testing equipment to make it reach optimum operational status; with present amount of inlet water, the best process control parameters are: under the circumstance where the ratio of anoxic zone and system’s total volume is 1:3, the dissolved oxygen concentration staying at 3mg/L or so, and the inner recycling ratio is 200%, it is feasible to reform to AO/ denitrification process after adjusting previous aeration tank. This paper proposes to optimize A2/ denitrification process into BdarePnho process with both the concentration of total nitrogen and the ammonia nitrogen concentration in the effluent under 10mg/L, and great nitrogen removal effect has been achieved. The optimal process parameter combination in the expansion process is:
