Columnar activated carbon oil refinery and petrochemical plant wastewater effluent any different. Columnar activated carbon adsorption process not only alone, but also with the physical chemical or biochemical singing singing other linked applications. Method instead of using biophysical study of law students pass away, and with the combination of activated carbon adsorption wears refinery wastewater treatment, the low, low, low solids content, with Nutshell addition to sewage, detergents, bubble aeration tank level with the corresponding energy Huaxiao With the landing, without investment and add a small amount of floor space. At the same time, easy to control with modulating activated carbon dosage. With longer retention of microbial carbon, its adsorption activity of activated carbon filling landed slower rates than many, and powdered activated carbon granular activated carbon cost than half of nothing more than a large consumption of powdered activated carbon. In the refinery wastewater, columnar activated carbon adsorption energies in hydrocarbon, and to the petrochemical plant effluent, the adsorption energy is contained in many varieties, but also more burdensome. In the refinery wastewater, petrochemical plant effluent, the singing or oily wastewater drainage process is the same as usual objects. Because this type of wastewater containing floating oil and suspended energy, does not deal directly with activated carbon affordable. Accordingly, the refinery wastewater, sewage treatment petrochemical plants, it is necessary to melt accumulation, melt pressure go up, and the combination of sand filtration pretreatment to remove the oil and suspended first effort on this foundation treated with activated carbon and more invalid. In the petrochemical plant effluent, often without planktonic effort, but has no intention occasional high value or high ratio, it is not necessarily with the melt, filtration pretreatment, but it is necessary to coal columnar activated carbon adsorption with activated sludge and other raw pass away with the application of chemical treatment method.
