Biochemical preparation for treating threonine fermentation sewage

The invention relates to a biochemical preparation for treating threonine fermentation sewage. The biochemical preparation is characterized by comprising a physical adsorbent and a composite microbial agent, wherein the composite microbial agent is prepared from the following raw materials by a volume ratio: 6 to 7 parts of arthrobacter sp., 5 to 7 parts of pseudomonas stutzeri, 5 to 7 parts of rhodococcus sp., 4 to 5 parts of bacillus amyloliquefaciens, 4 to 5 parts of clostridium papyrosolvens and 3 to 4 parts of scenedesmus obliquus. The biochemical preparation contains multiple microorganisms having good degrading capability to recalcitrant pollutants; various strains are reasonably matched to realize a good degrading effect; the biochemical preparation has a broad application prospect.
