摘要:
利用加载磁絮凝技术对垃圾渗滤液进行预处理试验,考察混凝剂PAC和助凝剂PAM投加量、pH值、磁粉Fe3O4投加量、磁场强度、药剂投加顺序等因素对试验的影响.结果表明,在pH为8.0,PAC投加量为600 mg/L,PAM投加量为0.25 mg/L,磁粉投加量为750 mg/L,磁场强度为150 mT条件下,先投加PAC再加入磁粉,30 s后投加PAM时,混凝效果最佳,COD的去除率为55.86%,氨氮的去除率为36.13%,浊度的去除率为88.91%.磁絮凝与常规工艺的对比试验表明,投加磁粉对于COD的去除有良好的效果,基本可以取代PAM的作用,但去除氨氮的效果低于PAM.
Abstract:
The technology of magnetic flocculation was used to pretreat the landfill leachate,the testing factors including the dosages of PAC(polyaluminium chloride), PAM(polyacrylamide)and magnetic powder Fe3O4, the influences on pH, magnetic field strength and dosing sequence. The removal rates of COD(chemical oxygen demand), ammonia nitrogen and turbidity were obtained by 55.86%, 36.13% and 88.91%, respectively, under the optimal conditions when pH was 8.0, PAC was 600 mg/L, PAM was 0.25 mg/L, magnetic powder dosage was 750 mg/L, and magnetic field strength was 150 mT. The comparative results between magnetic flocculation test and chemical flocculation tests show that the magnetic powder for replacing PAM is beneficial to test COD removal, but it is ineffective in ammonia removal.
