Abstract

Pollutant removal was researched in this paper, by using the improved constructed rapid infiltration system which was added sponge iron and special media of corn cob, and by taking wastewater of student life in campus as an object of study. Test results show that: after adding additional carbon corncob, the removal rate of total nitrogen increases by nearly 50% than conventional systems, so the effect is obvious. Corn cob can not only provide the required carbon source, but also can serve as microbial attachment carrier, and it is good for microbial growth. After the addition of sponge iron, the removal of total phosphorus rate is 92%, the average effluent concentration is 0.32mg / L, and the effluent can meet the —A of " Discharge standard of pollutants for municipal wastewater treatment plant(GB 18918-2002). The sponge iron achieves phosphorus removal by adsorption and chemical reactions. The improved system can also ensure the removal of COD and ammonia.
