摘要
采用化学沉淀法预处理部分含重金属废水,以Fenton氧化/混凝气浮/水解酸化/好氧曝气为核心工艺处理精细化工废水。该废水含有COD、氨氮、Cu^(2+)、Ni^(2+)等特征污染因子,处理水量为100 m^3/d。介绍了该废水处理工程的工艺流程、主要设计参数及设备配置。实际运行结果表明,该工艺对该废水具有良好的去除效果,系统对COD的去除率>94%、对TP的去除率>90%、对总铜的去除率>99%、对总镍的去除率>80%,出水水质完全满足当地污水处理厂的纳管标准,可为同类废水处理工程的设计和运行提供借鉴。
Chemical precipitation was used to pretreat part of the wastewater containing heavy met- als, and then the combined process of Fenton oxidation, coagulation floatation, hydrolysis acidification and aeration was applied to treat fine chemical wastewater. The treatment capacity of wastewater contains COD, ammonia nitrogen, Cu2＋ , Ni2＋ , and etc. is 100 m3/d. The technological process, design param- eters of main structures as well as equipment configuration of the project were introduced. The system showed good treatment effect, and the removal rates of COD, total phosphorus, total copper, and total nickel were higher than 94%, 90%, 99%, and 80%, respectively. The final effluent could meet the in- fluent requirements of local municipal sewage plant. The project could provide reference for design and operation of similar projects.
