According to the identified process, through the design of the grid, adjust the pool, upflow anaerobic reactor, A / O bioreactor, membrane bioreactor (MBR), nanofiltration and reverse osmosis devices and sludge concentration pool The design calculation of the main dimensions of the structure, the calculation of the hydraulic loss and the calculation of the pipeline, complete the design specification, the process flow chart (including the high-level arrangement), the layout plan and the main structure of the monomer map, and the pharmaceutical wastewater treatment plant plane and elevation Made a reasonable arrangement.

The design is technically feasible and economically sound. Investment costs of 6.4746 million yuan, operating costs of about 394.75 million / year, the average cost per ton of wastewater treatment is 21.63 yuan.

The design of the process is stable, small footprint, good handling effect, less secondary pollution. Using the current more mature treatment process, the sewage after treatment, Is expected to be able to reach the "pharmaceutical industry pollutant discharge standard mixed preparation category" (GB 21908-2008) emission standards. The actual effluent quality is roughly as follows: COD=100mg/L; BOD5=20mg/L；SS=70mg/L；NH3-N=15mg/L；SO42-=1.0mg/L；TP=0.5mg/L；PH=6-9. To achieve the purpose of eliminating pollution, realizing environmental protection and benefiting mankind.

Key words: Pharmaceutical wastewater treatment; UASB；A/O process；MBR；Nanofiltration ；reverse osmosis.
