摘要
采用向好氧池投加改性填料的方法,提升A2/O工艺低温条件下的脱氮能力及CODCr降解能力。结果表明,在冬季水温为10～12℃的条件下,生化系统对CODCr、氨氮和总氮的去除率分别为91.3%、99.6%和79.7%,出水水质达到了GB 18918—2002《城镇污水处理厂污染物排放标准》中的一级A标准。
For the purpose of enhancing the nitrogen removal and CODCr degradation ability of A2/O process under low temperature,modified filler was added into the aerobic tank.The results showed that,in winter season with water temperature of 10-12 ℃,the removal rates of CODCr,ammonia nitrogen and total nitrogen were 91.3%,99.6% and 79.7% respectively,the effluent water quality met the specification for class A grade 1 in GB 18918—2002 Discharge standard of pollutants for municipal wastewater treatment plant.
