摘要：

研究竹纤维生物膜载体生物接触氧化处理浙江临安横畈镇污水处理厂厌氧池出水效果,考察水力停留时间(HRT)和气水比对COD_Cr,NH₄⁺-N,TN和TP的去除效果。结果表明: 竹纤维生物膜载体反应器12天内即完成挂膜启动; HRT在8~15 h范围内,随着HRT增加,COD_Cr处理效果增强; HRT对NH₄⁺-N,TN和TP的去除效果影响较小; 试验范围内气水比对COD_Cr的去除效果无明显影响,NH₄⁺-N和TN的去除率随气水比的增加显著降低,分别从91.46%和46.12%降低至69.21%和36.43%,TP去除率则随气水比增加从29.18%升高至36.40%。竹纤维生物膜载体生物接触氧化反应器与污水处理厂活性污泥曝气池对比试验结果表明: 竹纤维生物膜载体生物接触氧化反应器对COD_Cr处理效果更好、耐冲击负荷能力更强。因此,采用竹纤维生物膜载体生物接触氧化对活性污泥曝气池进行升级改造是可行的。

Abstract:

Treatment of anaerobic effluent from Hengfan wastewater treatment plant in Lin'an with bamboo fiber biofilm carrier contact oxidation reactor was carried out. Effects of hydraulic retention time (HRT) and gas-water ratio on removal efficiencies in terms of chemical oxygen demand (COD_Cr), ammonium nitrogen (NH₄⁺-N), total nitrogen (TN) and total phosphorus (TP) were investigated. Results showed that the biofilm formation and startup of the reactor were finished in 12 days. When the HRT was between 8 h and 15 h, removal efficiency of COD_Cr increased with HRT. However, there were no significant variations in removal of NH₄⁺-N, TN and TP. Gas-water ratio did little effect on COD_Cr removal. The removal efficiencies of NH₄⁺-N and TN decreased from 91.46% and 46.12% to 69.21% and 36.43%, respectively, while that of TP increased from 29.18% to 36.40% with the increase of gas-water ratio. Comparison results of bamboo fiber biofilm carrier contact oxidation reactor and activated sludge aeration pond on COD_Cr removal indicated that the reactor was more efficient in removing COD_Cr and had better shock load tolerance. Thus, it is feasible to innovate the activated sludge aeration pond using the bamboo fiber biofilm contact oxidation reactor.
