Research Progress of Nitrogenous Wastewater Treatment with Entrapped Immobilized Microorganisms

Nitrogen pollution is becoming increasingly serious, more and more attention has been attracted to nitrogenous wastewater treatment. There are many problems in traditional biological technology, microbial immobilization techniques can complement the shortage of traditional methods in the biological nitrogen deficiencies, and achieve efficient denitrification. Entrapping method is not only the most widely used immobilization method, but also one of the hot researches at home and abroad. This paper mainly describes the principles of entrapped immobilization techniques and the commonly used carrier, as well as the reaserch progress of domestic and foreign scholars on the immobilized biological denitrifieation, and proposed problems needed to be solved for the practice of this technology.
