摘要:
为研究A2/O工艺对焦化产区废水处理效果以及该工艺抗负荷波动能力,选取贵阳某焦化厂区废水4个主要特征指标(COD、NH3-N、挥发酚、总氰化物)进行了系统的研究.结果表明:A2/O工艺对COD、NH3-N、挥发酚的去除效果良好,单一的A2/O工艺对废水中的总氰化物去除效果一般,约为10;左右,但A2/O工艺-芬顿试剂联用技术对总氰化物去除效果良好.另外,当系统中进水的COD负荷波动为100; ~ 148;时,其平均去除率在87;以上;当NH3-N负荷波动为100; ~ 152;时,其平均去除率在95;以上;当挥发酚负荷波动为100; ~ 353;时,其平均去除率在97.8;以上;当总氰化物负荷波动为100; ~ 139;时,其平均去除率在93;以上.这表明A2/O工艺具有良好的抗击负荷波动能力,适合焦化厂区废水处理.
Abstract:
To study the treatment effects and load fluctuate resistance ability of A/O process in the treatment of coke plant area wastewater,four pollutant(COD,ammonia,volatile phenol and total cyanide)were selected.The result shows that the process has a good and feasible removal of NH3-N,COD and volatile phenol,but the removal of total cyanide by the process is merely about 10%.When fenton reagent and A/O process were combined and used,the removal rate is up to 93%.At the same time when the load fluctuation of COD is 100%~148%,the average removal rate is more than 87%.while the load fluctuation of NH3-N is 100%~152%,the average removal rate is over 95%.the average removal rate is more than 97.8%,while the load fluctuation of volatile phenol is 100%~353%.the removal rate is above 93%,when load fluctuation of influent total cyanide is 100%~139%.All those show that the process has good impact resistance and can ensure the stability of effluent quality.
