The SBR process to treat municipal sewage conducted a preliminary test, proposed performance indicator indicator microbes as the reactor operation . Traditional SBR process process is simple , the treatment effect is stable , small footprint, and resistance to shock loading capability , flexible operation . The Meizhou SBR urban wastewater will be put into operation for the first time , quickly and accurately on running performance to be monitored to ensure the efficient operation of the reactor , is the focus of the follow-up of the sewage treatment plant . This conditions determined by comparison of SBR wastewater treatment process conditions as well as the corresponding run control parameters, and then examine the stable operation of each pollutant removal , simultaneous detection of microorganisms in the sludge acclimation process and stable operation phase change . In the above experiments on the basis of the mechanism of action of micro-organisms on the sewage treatment . Experimental results show that the SBR method of CODcr of urban sewage , TN , TP , ammonia has a good removal efficiency . COD cr removal rate of 84% to 87 % . BOD 5 removal rate of 88% to 92% , ammonia nitrogen removal rate from 53 % to 78% , total nitrogen removal efficiency of 27 % to 40 % of the asked , TP the removal of the 74 % to 78% . Examine biological activated sludge mixture , sludge and gray brown , compact structure , protozoa variety, normal and stable system operation . Higher than the number of bacteria in the stable operation of activated sludge mixture up and running of 33 times , sessile ciliates protozoa dominant in the water quality is good , reaching 10 4 of magnitude . However , in adverse conditions , the number of flagellates increased water turbidity . Experimental results show that the miniature animals, especially protozoa to the adverse conditions to respond to , play an important role in guiding the reactor running , to ensure the efficient and stable operation of the system .
