xinchang pharmaceutical factory ---- reconstruction of amount renovation

zhejiang medicine co., ltd. xinchang pharmaceutical factory is a national key new & hi-tech enterprise, mainly manufacturing medicines like vitamin, antibiotics and reifamycin. sewage from this factory is very hard to be treated for its quite complex composition and more than 4% salinity.

  its original sewage treatment amount is 1000t/d,it uses active sludge process, loading of cod is only about  1kg/(mз.d),hydraulic detention time is 10.5d。
  influent cod:10000~15000mg/l, nh3-n:200~400mg/l;
  effluent cod:600~1000mg/l,        nh3-n:300~500mg/l。
  because of production expansion,now the volume of effluent required to upgrade to2000t/d above,cod loading must >2kg/(mз.d),so need for an urgent transformation。
  transformation requirements:
  1、dealing with water >2000t/d,influent cod load> 2kg/(mз.d);
  2、effluent cod:  <1000mg/l, nh3-n:200~300mg/l。
