【Abstract】 In the paper, to improve the reclamation rate of wastewater, the process and efficiency of submerged membrane bioreactor for removing phosphorus in wastewater were studied. Anaerobic process was adopted in the biological process, and the phosphorus removal rate (PRR) could be over 63%. Compared with the process without an anaerobic one, 32% of improvement of PRR could be gained. Al 2(SO 4) 3 was added in the reactor for removing the phosphorus in a chemical way at the same time with the biological process, and the average phosphorus removal rate could reach 82%. However, the activity of the active sludge should be maintained in all the process. The result of this research showed that the submerged membrane bioreactor is effective in removing phosphorus. The anaerobic process and the chemical process, which were adopted in the process, could greatly enhance the phosphorus removal rate of the reactor.更多还原
