Embodiment Construction
[0018] Now in conjunction with accompanying drawing, invention is described in further detail. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the invention in a schematic way, so they only show the composition related to the invention.
[0019] figure 1 It is a schematic diagram of the framework of the present invention.
[0020] as attached figure 1 As shown, the pharmaceutical wastewater from the pharmaceutical factory is sent into the coagulation sedimentation tank, and at the same time, the coagulant PAC (polyaluminum chloride) and the flocculant PAM (polyacrylamide) are added to the coagulation sedimentation tank to capture the unwanted impurities in the wastewater. Dissolved organic matter, degradation of wastewater COD.
[0021] Then the wastewater flows into the hydrolytic acidification tank for treatment. High-efficiency biological braided fillers are placed in the hydrolytic acidification tank to hydrolyze suspe...

The invention relates to the technical field of wastewater treatment, in particular to a method for treating pharmaceutical wastewater. The method comprises the following steps: (a) the wastewater isfed into a coagulation sedimentation tank, and insoluble organic matter in the wastewater is captured and COD in the wastewater is degraded by adding a coagulant and a flocculant into the wastewater in the coagulation sedimentation tank; and (b) the wastewater in the coagulation sedimentation tank flows into a hydrolysis acidification tank, and a biological braid type filler is placed in the hydrolysis acidification tank. According to the method, the organic matter in the wastewater is captured and the COD in the wastewater is degraded through the coagulation sedimentation tank; suspended matter and soluble organic matter in the wastewater are hydrolyzed into organic acids through the hydrolysis acidification tank; the wastewater is continuously aerated, BOD in the wastewater is removed and phosphorus in the wastewater is absorbed through a primary contact oxidation tank and a secondary contact oxidation tank; water is separated from sediment through a secondary sedimentation tank; thewastewater is filtered into reusable water through a continuous membrane filtration system; and the pharmaceutical wastewater can be treated into the reusable water, so that the recycling of the water is realized.
Description
technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a method for treating pharmaceutical wastewater. Background technique [0002] The existing pharmaceutical wastewater from pharmaceutical factories needs to be treated. However, the treatment method of the existing traditional technology can only treat the wastewater into the wastewater that meets the discharge standard, but cannot treat the wastewater into reusable water. Contents of the invention [0003] In order to solve the technical problems described in the background technology, the invention provides a method for treating pharmaceutical wastewater, which uses a coagulation sedimentation tank to capture organic matter in the wastewater and degrade COD of the wastewater. The suspended solids and soluble organic matter in the wastewater are hydrolyzed into organic acids through the hydrolysis acidification tank. Through the primary contact oxidation tank an...
