摘要:

针对高浓度含钒碱性工业废水的特点,经多次比较试验得出最佳处理方法:还原—中和—絮凝法.详细探讨了还原剂用量、还原反应的最佳pH、还原反应时间、中和沉淀过程的pH、助凝剂等因素对废水中钒残留量的影响.实验结果表明,在最优实验条件下,处理后废水中钒<0.001g/L,出水达到国家废水排放标准.

关键词: 钒, 还原, 中和, 絮凝剂, 废水处理

Abstract:

Aiming at the characteristics of the highly concentrated vanadium-containing industrial wastewater,the best treatment method,reduction -neutralization-flocculation process has been obtained by means of many comparison tests.The effects of the factors, such as the dosage of reducing agent,the best pH of reductive reaction,reductive reaction time,pH of neutralization and precipitation,coagulant aids etc.on the residual vanadium in wastewater are discussed in detail.The results show that under the optimal conditions,the vanadium-content in the treated water is below 0.001 g/L,and the effluent water reaches the national wastewater discharge standard.

Key words: vanadium, reduction, neutralization, flocculants, wastewater treatmen
