The invention relates to the technical field of high-salt 
sewage treatment, and especially relates to a technology for treating high-salt 
sewage by using high salt-resistant 
denitrifying bacteria. Thetechnology comprises the following steps: the high-salt 
sewage is discharged into a coarse screen 
pool and is treated, and the high-salt sewage treated with the coarse screen 
pool is discharged intoa fine screen 
pool, and is treated; and the high-salt-resistant 
denitrifying bacteria which are well domesticated and cultured in advance are added to 
sludge to prepare 
activated sludge. Denitrifyingbacteria are directionally domesticated to make the 
denitrifying bacteria have high 
salt resistance, the high salt-resistant denitrifying 
bacteria are used to prepare the 
activated sludge and an active bio-filler, and the 
activated sludge and the active bio-filler are respectively used to treat the high-salt sewage in order to effectively reduce nitrites in the high-salt sewage to generate harmless 
nitrogen, so harms of the nitrites are eliminated, the 
nitrogen nutrition is consumed, excessive multiplication of 
algae is inhibited, water is purified, and 
pathogenic bacteria are inhibited.
