玄武岩纤维填料强化A/O工艺处理生活污水
|
摘要
为了增强常规A/O工艺脱氮及抗冲击负荷性能、减少剩余污泥产生,在缺氧池及好氧池内加入玄武岩纤维(BF)填料,研究BF填料强化A/O工艺脱氮效率、抗冲击负荷性能及污泥减量效果。结果表明:强化A/O工艺对生活污水中COD、NH_4~+-N和TN具有较高的去除效果,其去除率分别可达95%、98%和86. 3%。对于高负荷有机废水,与常规A/O工艺相比,强化A/O工艺出水效果稳定,抗冲击负荷性能增强,NH_4~+-N和TN的平均去除率分别提高了19%和20. 9%。污泥产率为0. 19 kg/kg(以COD计),较常规A/O工艺降低了40. 6%。
In order to enhance the denitrification and impact load resistance of the conventional A/O process and reduce the residual sludge production,basalt fiber( BF) packing materials were used in the anoxic tank and the aerobic tank. The denitrification efficiency,impact load resistance and sludge reduction effect of the enhanced A/O process were studied. The results showed that the BF packing materials enhanced A/O process had a high removal efficiency on COD,NH_4~+-N and TN in domestic sewage,and the removal rates reached 95%,98% and 86. 3%,respectively. For high-load organic wastewater,compared with the conventional A/O process,the enhanced A/O process had more stable effluent quality and the enhanced impact load resistance. The average removal rates of NH_4~+-N and TN were increased by 19%,20. 9%,respectively. The sludge yield was 0. 19 kg/kg,which was 40. 6% lower than the conventional A/O process.
