利用AB技术处理高浓度石油化工废水的研究

本文利用ＡＢ法废水生物处理技术进行治理高浓度石油化工废水的试验研究，通过ＡＢ法和普通活性污泥法处理高浓度石油化工废水对比性试验，系统地考察了两种方法的进水负荷、耐冲击负荷、活性污泥性状和处理效率等指标。研究结果表明：ＡＢ法在进水ＣＯＤ为１６００ｍｇ／Ｌ，ＢＯＤ５为８００ｍｇ／Ｌ，苯酚浓度为６００ｍｇ／Ｌ，总容积负荷为１２ｋｇＣＯＤ／ｍ＾３ｄａｙ的条件下，ＣＯＤ去除率为９６．５％，ＢＯＤ５去除率达９

The Research of High Concentration Petro-chemical Wastewater Treatment by AB Technology

This article uses AB method of waste water biological treatment technologycarrying out experimental researches on bringing high concentration petrochemicalwastewater under control. By means of contrast experiments between AB method andprimary common activated -- sludge process. Both methods of input loading and shockresitance, and treatment efficiency of biological properties of activated -- sludge, and so nohave been investigated systematically. The result shows that when input COD is 1600mg/L,BODS is 80mg/I-, phenol concentration is 600mg/I-, and total volume loading is 12 kgCOD/m3day, COD removing rate is 96. 5 percent and BODS removing is upto more than 98percent. By using AB method, shock resistance loading has increased more, motion is morestable and it is easierto operate and manace, than by using common activated -sludgeprocess. The treatment ability of the former is fourorfive times as much as tlhat of the latter.
