Zeolite filter material is aluminum silicate minerals, the appearance of white or red brick, is a weak acid cation exchanger, the artificial imported active component. Has the new ion exchange and adsorption capacity, adsorption capacity also increases accordingly, it is mainly used for middle and small boiler water softening treatment, to remove the calcium and magnesium ions in the water, thereby reducing the service life of the boiler scale. In wastewater treatment, can be used to remove phosphorus in the water and lead and hexavalent iron. After failure of zeolite available concentrated brine countercurrent regeneration reuse.
As the BAF with zeolite filter material can effectively remove COD, ammonia nitrogen and turbidity, try the best test conditions hydraulic load of 2.2 m/h (hydraulic retention time of 1.4 h), at this time of the removal rate of COD, ammonia nitrogen and turbidity are 73.9%, 88.4% and 73.9% respectively, and the corresponding water average concentration of 43.4 mg/L respectively, 3.5 mg/L and 3.7 NTU, can achieve the state environmental protection administration, tianjin university suggest recycle cooling water quality values (| | |) requirements of related indicators. Using zeolite and sand filter materials as BAF filter material treatment of textile wastewater. Cell count results show that, zeolite filter m aterial on the growth of the number of nitrifying and denitrifying bacteria bacterium were 3.0 x 108 and 2.2 x 109 CFU/mL) and the number of growing on sand filter, respectively is 4.5 x and 6.5 x 108 108 CFU/mL. From point of view, the number of nitrifying bacteria on zeolite filter material is more suitable for microbiological nitrification, the other from the perspective of organic matter and TKN removal and the effect of the BAF with zeolite as the filter material is better in BAF with sand as filter material. Using zeolite as the filter material of BAF can make textile wastewater COD removal rate of 86% ~ 92%, BOD removal rate was 99%, and the chroma removal rate from 77% to 79%, this is due to the specific surface area of the natural zeolite filter material is greater than the sand filter material, like microbial adhesion, and zeolite filter material of the ion exchange capacity is strong, can be adsorbed NH4 + in the water, and suitable environment of nitrifying bacteria growth, transformation of NH4 + to nitrate.
Particle size can be made according to need, the flow regime is good, filtration cycle is long, backwash easier for roads, sewage capability is strong.
