[Pollution removal efficiency of powdered activated carbon and microfiltration integrated process].
The removal effects by PAC-MF integrated system for organic matters, pesticides and ammonia-nitrogen are introduced. The separate contribution of PAC, microorganism and MF in the system are detailed quantitatively. The results indicate that the average removal rates of the integrated process for TOC, UV254, THMFP and HAAFP are 73.56%, 96.75%, 77.64%, 83%, respectively, and 95.1% for pesticides dichlorvos, 98% for ammonia-nitrogen. The results illustrate that PAC significantly reduces the membrane organic burden to 28.32% of the direct membrane filtration without PAC; and carbon layer on the surface of membrane has the removal effect for pollutants. Moreover, the PAC used in high concentration can largely improve its adsorption performance for ammonia-nitrogen, whose removal rate is 44.5%.
