针对分散式生活污水处理领域存在的问题
设计了一种新型的一体化工艺
并考察了水力停留时间(HRT)、温度、碱度对新工艺处理生活污水效果的影响.结果表明
当HRT在6~12 h之间变化时
HRT对处理效果没有显著的影响;温度、碱度对化学需氧量(COD)的去除影响不大
但对NH3-N
TN的去除却有显著的影响
温度由15℃上升至25℃时
NH3-N
TN的去除率分别提高了37.3%
22.1%;碱度由不充足变为充足时
NH3-N
TN的去除率分别由71.8%
40.5%提高到97.0%
50.3%.在最佳的运行条件下
出水中COD
NH3-N
TN的浓度均达到了城镇污水处理厂污染物排放标准(GB18918-2002)中的一级排放标准
其平均去除率分别为95.7%
97.0%
50.3%.
To solve the problem existed in the field of decentralized domestic wastewater treatment
a novel integrated biofilm process was designed
and the effects of hydraulic retention time(HRT)
temperature
alkalinity on the removal of domestic wastewater were studied.The results show that
with HRT beteen 6~12 h
HRT has little effect on removal efficiency;temperature and alkalinity distinctively affect NH3-N and TN removal although they have little impact on chemical oxygen demand(COD) removal
when temperature increases from 15 ℃ to 25 ℃
the removal efficiency of NH3-N and TN are increased 37.3% and 22.1% respectively;when alkalinity changes from insufficient to sufficient
the removal efficiency of NH3-N and TN are enhanced from 71.8% and 40.5% to 97.0% and 50.3% respectively.At optimum operating conditions
the concentration of COD
NH3-N
TN in effluent meet the first class criteria specified in the national discharge standard of pollutants for municipal wastewater treatment plant(GB18918-2002)
the removal rate are 95.7%
97.0%
50.3% in average respectively.
