New technology on treatment of nitrite wastewater of high concentration using sulfaminic acid enhanced by microwave
Nitrite wastewater of high concentration was extremely harmful to human health and hard to treat for its toxicity by biological method.Technology using sulfaminic acid enhanced by microwave was invented to solve the problem.Under condition of microwave equipment with alterable powet.which had accelerated the reaction,a more efficient,quicker and more widely used technology was carried out to treat the nitrite wastewater of high concentration using sulfaminic acid.According to the technology.the reaction between sulfarninic acid and NO2 was very fast as NO2 was turned into nitrogen without leaving any sludge and secondary pollutants.Besides the removing of NO2,the technology could also reduce the COD of the wastewater to satisfy the standard of wastewater output or make it suitable for further biological treatment.
