电化学氧化耦合纳米催化微电解技术处理腈纶废水的静态实验研究

Research on Static Experiment of Acrylic Fiber Wastewater Treatment by Electrochemical Oxidation Coupling with Nanocatalytic Microelectrolysis Technique

以抚顺腈纶厂生化池出水为研究对象,以CODCr和NH3-N去除率为考察指标,对电化学氧化耦合纳米催化微电解技术处理腈纶废水进行了静态实验研究。结果表明,电化学氧化耦合纳米催化微电解技术受电流强度、水力停留时间和电解质投加量三个因素的影响,对NH3-N有良好的处理效果,NH3-N去除率达90%以上;但对CODCr的处理效果不佳,只受水力停留时间的影响比较显著,当水力停留时间为10 min时,出水CODCr浓度能满足GB 8978-1996中一级排放指标(CODCr≤100 mg.L-1)。为进一步的动态实验奠定了基础。

With biochemical pool of Fushun Acrylic Plant effluent as research object,the removal rates of CODCr and NH3-N as indexes,the static experiment of acrylic fiber wastewater treatment by electrochemical oxidation coupling with nanocatalytic microelectrolysis technique was studied.The results showed that this technique was affected by current,HRT and electrolyte amount,and it had better treatment effect for NH3-N with the removal rate of above 90%;but its treatment effect for CODCrwas not good,which was only affected obviously by HRT.When the HRT was 10 min,the effluent CODCr concentration could met the standard of less than 100 mg·L-1 required by GB 8978-1996.It provided basis for further research of dynamic experiment.
