Nitrided artificial soil for treatment of high concentration ammonia nitrogen-containing wastewater

摘要

The present invention relates to a nitrifying artificial soil for treating high concentration ammonia nitrogen-containing wastewater,;Peat moss, cultivated soils, sand of 0.5-2 mm in diameter, and 0.5-2 mm diameter zeolite from natural zeolites with a cation exchange capacity of 100-170 meq / 100 g,;95 to 105: 95 to 105: 95 to 105: 95 to 105,;Based on the mixed soil, a nitrification artificial soil containing 55 g / l or more of steelmaking slag is prepared.;According to the present invention, there is provided a method for treating ammonia nitrogen which is responsive to a soil's natural purification ability, and it is possible to develop a soil treatment system that can be applied to industry,;In addition, it is expected to recycle waste and increase its cost by using steelmaking slag as a by-product waste for steelmaking for the first time in water treatment.
