The invention discloses a method for
processing mixed waste water in a pharmaceutical
chemical industry park, and belongs to the
water processing field. The method comprises the following steps: after regulation of water quantity and
water quality is performed to the
mixed waste water in the pharmaceutical
chemical industry park, the
mixed waste water flows into a hydrolytic tank, the hydrolytic tank is filled with suspension type filling material inside, and an up-flow type water
distribution method is adopted; the water outlet of the hydrolytic tank enters into an anaerobic tank, the anaerobic tank also adopts an up-flow type water distributing method; the water outlet of the anaerobic tank enters into a
moving bed biofilm reactor, suspended filling is added into the
moving bed biofilm reactor, and an
aeration device is arranged on the bottom of the tank; the water outlet of the
moving bed biofilm reactor enters into a biological aerated filter through adopting the form of sprinkling at upper part, and
ceramic filling is added into the biological aerated filter; the water outlet of the biological aerated filter enters into a
sedimentation tank and a coagulation reaction tank for deposition in sequence. According to the characteristics of
high concentration and complex component of the
organic matter of the mixed waste water in the pharmaceutical
chemical industry park, the invention can perform rapid and highly efficient treatment at a
proper time, the water outlet can meet the latest
pharmaceutical waste water discharge standard of the state, and the COD is less than 100 mg / L.
