The sewage treatment plant needs to monitor BOD5 and CODcr values of inlet water and outlet water, and knows the biodegradability of sewage through B/C, thereby having important process guidance significance. However, no monitoring equipment capable of simultaneously monitoring BOD and CODcr values on line and accurately giving B/C values exists in the current market, and data support cannot be provided for timely adjustment of the process. The detection of BOD index mainly includes five-day culture method and microbial membrane method. The BOD5 method is long in time consumption, can only depend on laboratory conditions at present like the microbial membrane method, cannot quickly obtain data, and does not have reliable BOD monitoring equipment capable of running online for a long time. The correlation research of BOD and CODcr and UV254 index is not enough.
