Embodiment 1

[0046] A method for advanced treatment of effluent water from sewage treatment stations of pharmaceutical factories in this embodiment, the process flow can be found in figure 1 , the specific steps are:

[0047] (1) The effluent from the wastewater treatment station of pharmaceutical companies enters the regulating tank through the pipeline for water volume and homogeneity adjustment, and then the wastewater enters the first-stage coagulation sedimentation tank, which adopts the form of inclined plate sedimentation tank, and the dosage of coagulant polymerized ferric chloride 60mg / L, can effectively remove most of the suspended matter, reduce the consumption of suspended matter on the ozone of the ozone oxidation system, improve the efficiency of ozone oxidation, and discharge the sludge from the coagulation sedimentation tank into the sludge concentration tank for concentration; Oxidation tank, ozone gas is passed into the ozone oxidation reaction tank, the dosage of ozone i...

Embodiment 2

[0055] A method for advanced treatment of effluent water from sewage treatment stations of pharmaceutical factories in this embodiment, the process flow can be found in figure 1 , the specific steps are:

[0056] (1) The effluent from the wastewater treatment station of pharmaceutical companies enters the regulating tank through the pipeline for water volume and homogeneity adjustment, and then the wastewater enters the first-stage coagulation and sedimentation tank. The pool sludge is discharged into the sludge thickening tank for concentration; the effluent enters the first-stage ozone oxidation tank, and ozone gas is passed into the ozone oxidation reaction tank. The ozone dosage is 200mg / L, and the hydraulic retention time for the ozone oxidation reaction is for 30min. The top of the reactor is equipped with a tail gas destroyer to remove the remaining ozone in the tail gas, and the effluent enters the stabilization tank to remove the residual ozone in the water.

Abstract

The invention belongs to the field of deep treatment of waste water and particularly relates to a deep treatment process and equipment of pharmaceutical waste water being stricter than class-A standards. The deep treatment equipment of the pharmaceutical waste water being stricter than class-A standards comprises an adjusting pond, a first-stage coagulating precipitation pond, a first-stage ozoneoxidation pond, a stabilizing pond, a hydrolytic acidification pond, an aerobic MBBR (Moving Bed Biofilm Reactor) pond, a secondary precipitation pond, a denitrifying biological filter, an aeration biological filter, a second-stage coagulating precipitation pond, a sand filter, a second-stage ozone oxidation pond and a disinfecting pond. The deep treatment process and equipment of the pharmaceutical waste water being stricter than the class-A standards has the advantages that according to the characteristics of complex components, high chromaticity, large toxicity and extremely poor biodegradability and the like of discharged water from a sewage treatment station of a pharmaceutical factory, physical and chemical processes, an advanced oxidation technology and a biological technology are reasonably combined and applied, and after treatment, the discharged water can meet the requirements of class-A local discharge standards.

Description

technical field [0001] The invention belongs to the field of advanced treatment of waste water, and in particular relates to a process and equipment for the advanced treatment of pharmaceutical waste water which is stricter than the Class A standard. Background technique [0002] Pharmaceutical wastewater has a high concentration of organic pollutants, complex components, and contains a large amount of toxic, harmful, and biodegradable substances. Difficult to treat industrial wastewater. After the pharmaceutical wastewater has been treated by the biochemical system of the sewage treatment station in the factory for a long time, the biodegradable organic matter has been basically removed, and most of the remaining organic matter is refractory organic matter, part of which is extremely difficult to degrade in the wastewater itself, and part of it is microbial degradation The metabolites produced by organic matter have extremely poor biochemical properties and are not suitabl...
