一体式曝气生物滤池脱氮性能研究

his paper taking one of taiyuan city economic and technological development zone wastewater treatment process for experimental base, after 10 months of startup and commissioning, focus on the prototype integrative biological aeration processing craft processing urban sewage of denitrification performance. The research results show that the water pollutant concentrations higher, biodegradability of poor performance, water quality index volatile situation (BOD5 40-180 mg/L, average 160 mg/L; CODCr 100-950mg/L, average 380 mg/L; SS 100-1500 mg/L, average 280 mg/L; NH3- N 15-35 mg/ L, average 26 mg/L; TN 20-65 mg/L, average 35 mg/L; TPaverage was 2.86 mg/L), prototype integrative biological aeration system water-quality, except TP outside all can reach the standard GB 18918-2002 A standard, the primary water pollutants concentration are respectively: BOD5 5.3 mg/L, CODCr 38mg/L, SS 7mg/L, NH3 -N 3.7 mg/L (6.0 mg/L), TN 13.2 mg/L, TP 1.65 mg/L, Each pollutant removal of average respectively: BOD5= 96.7%, CODCr = 90%, SS = 97.5%, NH3-N = 85.7% (77.1%), TN = 62.5%, TP = 42.5%. Phosphorus chemical phosphorus, need to assist in the second pond with Wells malign add flocculant and purify.
