| Abstract: | UASB-contact oxidation-air support used to treat citric-acid wastewater is introduced. Operation shows that under the influent conditions of SS = 3427 mg/L, COD = 18 853 mg/L and BOD5 = 11 778 mg/L, SS, COD and BOD5 of the effluent are 147.5 mg/L,223 mg/L and 51.9 mg/L respectively. Compared with other processes, applying the method to treat citric-acid wastewater, may have such advantages as less land occupation, low engineering investment and operation cost, and stable treatment effect. |
