摘要
采用厌氧—好氧法处理石化废水，试验结果表明：石化废水经厌氧处理以后，其好氧可生化性提高２０％～３０％．当厌氧反应器进水有机负荷为５．２ｋｇＣＯＤ／ｍ３ｄ，水力停留时间为２４ｈ时，ＢＯＤ５去除率为８５％，ＣＯＤ去除率８３％，油去除率９１％；当曝气池污泥负荷为０．４５ｋｇＣＯＤ／ｋｇＭＬＳＳ·ｄ，水力停留时间为４ｈ时，ＢＯＤ５去除率为９４％，ＣＯＤ去除率为９３％，油去除率为９６％．系统总ＣＯＤ去除率９８．８％，ＢＯＤ５去除率为９９％．
In this paper, the authors put forward a method of treating petro chemical wastewater by anaerobic and aerobic biological process. The experiments have shown that aerobic bio degradability can be increased by 20 %～30 % after the petro chemical wastewater is treated by anaerobic process, when F r=5 2 kg COD/m 3·d, HRT=24h in the anaerobic reactor, the BOD 5 removal is 85 %, COD removal 83 % and oil removal 91 %; As N s =0 45kg COD/kg MLSS·d, HRT =4h in the aerobic tank, the BOD 5 removal is 94 %, COD removal 93 % and oil removal 96 %. The total COD removal is 98.8 % and BOD 5 removal 99 %.
