UASB-生物接触氧化处理四氢呋喃废水的试验研究
|
摘要
西安某化工厂生产废水中含有四氢呋喃,废水量每日约4500吨,废水混浊微黄,有刺激性气味,pH值约为8.5,出水COD为21451.47mg/L,BOD约为4000mg/L,BOD/COD比值小于0.2,属于高浓度难生化降解废水。本实验采用UV/Fenton试剂氧化法对该污水先进行预处理,经预处理后,进一步采用UASB和好氧生物接触法分别及联合工艺进行生化处理。
实验总时间5个多月,在前三个多月中,利用UASB反应器培养出了适应处理四氢呋喃废水的良好的颗粒污泥,好氧生物接触池也形成了成熟的生物膜。随后分别对UASB反应器和好氧生物接触池运行参数进行了优化。实验研究表明:UASB最佳水力停留时间为24h、温度为35℃、进水SS<100mg/L、碱度在1000～200mg/L之间为宜、pH为7.0～8.0、可承受的最大容积负荷为6.0 kgCOD_(Cr)/(m~3·d),在上述最佳运行条件下UASB反应器对UV/Fenton处理后四氢呋喃废水的COD的去除率达90%以上,并有一定的抗冲击能力;好氧生物接触池最佳运行条件为:pH在7.0～8.0之间,HRT为12小时,温度在20℃,DO为5mg/L,在上述最佳运行条件下接触池对UASB出水COD去除率在95%以上。在UASB和好氧生物接触池都处于最佳运行条件下,联合生化工艺的对UV/Fenton处理后四氢呋喃废水的CODcr总去除率可达99%。
The production wastewater of one chemical factory contain THF in xi'an,and the quantity of wastewater is about 4500t/d.The wastewater is muddy,lunatia,and has irritating odor.pH is about 8.5,The COD and BOD is 21451.47mg/L and 4000mg/L,and BOD/COD is less than 0.2,.It is belongs to the high concentrations and difficult biochemistry degeneration wastewater.In the experiment,the way of pretreatment is UV/Fenton oxidation,then using UASB and biological contact oxidation to treat further.
The total time of the experiment is more than 5 months.In the first three months,the UASB reactor cultivated the good granular sludge adapted to the THF wastewater,and the biological contact oxidation formed a mature biofilm.In the next experiment come the best operational parameters of UASB and biological contact oxidation by changing the conditions of experiment.Test results showed that for UASB,the best conditions are as following: HRT=24h,T=35℃,SS＜100mg/L,Alk=1000mg/L-1200mg/L,C:N:P=250:5:1,pH=7.0 - 8.0,Nv= 6.0 kgCODCr/(m~3·d).Under the conditions,the removal rate of UASB is over 90%, and the UASB reactor has the ability of impact.For the biological contact oxidation,the best conditions are as following:pH=7.0-8.0,HRT=12h,T=20℃,DO=5mg/L,and the removal rate is over 95%.In the best conditions,the removal rate of combination process is over 99%.
