The method includes: charting the standard curve, establishing the mathematical model, and measuring the concentration of the DON in the secondary effluent. Based on establishment of the mathematical model among the concentration of the DON in the sewage and the contents of the protein and the HA therein, the concentration of the DON in the secondary effluent is calculated by the directly measured contents of the protein and the HA therein, and besides the constituents of the DON are provided, which reflects the treating effect of the wastewater treatment plant. The method of the invention features in accurate measurement, convenient operation, and strong applicability. 171/2 ct) 'Co.~ cl ctf -o ct ~~ U 0 40 ot *~C 0 - o c - 0 - ~ I)~ * _ _ _ _ _ _ -ct --- J L -j - -- -----------------------------------e- ------
