New-generation sewage biological advanced treatment up-to-standard discharge system

The invention discloses a new-generation sewage biological advanced treatment up-to-standard discharge system, and relates to the technical field of sewage treatment. The system comprises a collectionpool, an ion adding machine I, an ion adding machine II and an ozone machine. According to the new-generation sewage biological advanced treatment up-to-standard discharge system, fibers in wastewater are separated and removed or recycled through the arranged primary ionization physicochemical tower, then the treatability of the wastewater can be improved through the secondary hydrolysis acidification tower, and the pH value can be stabilized; wastewater is subjected to dosing flocculation and most of insoluble CODcr and BOD5 and part of soluble CODcr and BOD5 in the air floatation tank, theacidified and homogenized wastewater enters the anoxic tank and then enters the biochemical tank to be subjected to aeration biochemical treatment after being subjected to anaerobic treatment by the IC anaerobic tower, and mos
