The main task is to plete a the region of the sewage processing design. Miyang sewage treatment plant the construction scale: 30000 m3/d。 The original water: CODCr: 420mg/L, BOD5:200mg/L。 SS: 300mg/L。 NH3N: 20mg/L。 TN:40mg/L。 TP:after the country the urban sewage treatment plant emissions standards (GB189182020) level 1B standard requirements: CODCrthan60 mg/L, more than 20mg/L BOD5, SS than 20mg/L, NH3N than 8mg/L, TP than mg/L. In this paper, according to the feed water quality, water and water situation, analyses and pares the all kinds of wastewater treatment process, determine the sewage treatment plant using the A/A/O process, the sludge produced by the enrichment, sinotrans after dehydration. The main design content includes: choosing the wastewater treatment process and the process of design unit 。 The sludge treatment process design, (including process flow and the determination of the monomer structures design)。 Sewage treatment plants the plane and elevation layout .
