- Title:
- Design and Operation Effect of Nitrobenzene Wastewater Treatment Project
摘要:- 采用電化學還原+三段式生化+改良型芬頓組合工藝處理硝基苯廢水，介紹了工藝流程、主要工藝設(shè)計參數(shù)，以及對主要污染物的去除效果。工程運行結(jié)果表明，該工藝對硝基苯廢水處理效果好、費用低，且具有顯著的抗沖擊性能。該工程在進水主要污染物指標均值COD為1 159 mg/L、SS為75 mg/L、硝基苯為96.6 mg/L、色度為650倍、pH值為9.4、NH3-N為26 mg/L、TN為960 mg/L的情況下，處理出水主要污染物指標均值COD為42 mg/L、SS為7 mg/L、硝基苯為0.3 mg/L、色度為15倍、pH值為6.6、NH3-N為1 mg/L、TN為10 mg/L，滿足山東省《流域水污染物綜合排放標準 第1部分：南四湖東平湖流域》（DB 37/3416.1—2018）要求。
Abstract:- The combined process of electrochemical reduction, three-stage biochemical treatment and modified Fenton was used to treat the nitrobenzene wastewater. The process flow, main design parameters, and the removal effect of major pollutants are summarized. The engineering operation results show that the process has good treatment effect on nitrobenzene wastewater, low treatment cost, and significant impact resistance. In this project, the average influent COD, SS, nitrobenzene, chroma, pH,NH3-N and TN are 1 159 mg/L, 75 mg/L, 96.6 mg/L, 650 times, 9.4, 26 mg/L, and 960 mg/L, respectively. The average effluent COD, SS, nitrobenzene, chroma, pH, NH3-N and TN are 42 mg/L, 7 mg/L, 0.3 mg/L, 15 times, 6.6, 1 mg/L, and 10 mg/L respectively, which meet the requirements of Integrated Wastewater Discharge Standard for Basin Part 1: Nansi Lake and Dongping Lake Basin (DB 37/3416.1-2018) in Shandong Province.
