[Ecological engineering experiment for Jinshan Lake in Zhenjiang base on techniques of immobilized nitrogen cycling bacteria].
Nitrogen cycling bacteria, including ammonifying, nitrobacteria, nitrosobacteria and denitrifying bacteria were screened, carrier was made and immobilized nitrogen cycling bacteria (INCB) was prepared. The results demonstrated that ammonifying, nitrobacteria, nitrosobacteria and denitrifying bacteria were increased markedly in the experimental areas and root zone of aquatic plants by releasing of INCB. The results also showed that the average removal efficiencies for total N (TN), NH4(+) -N, NO3(-) -N and NO2(-) -N were 44.70%, 67.17%, 31.79% and 74.21%, respectively. Furthermore, NH4(+) -N, total N (TN) reached the National Standard II and IV for surface water, respectively. With INCB, local lake water quality could improve. Therefore, the technique of INCB could play an important role for remedying and rehabilitating in desertification water.
