摘要
皮革综合废水采用“预曝气脱硫脱氮→一级物化沉淀→A-O工艺→二级物化沉淀→曝气生物滤池”组合工艺进行处理,出水水质稳定达到《制革及毛皮加工工业水污染物排放标准》(GB30486-2013)限值要求,采用预曝气脱硫脱氮工艺能有效去除废水中NH3-N和S2-,降低废水生物毒性。
The leather comprehensive wastewater was treated by the combination process of pre-aeration desulfurization and denitrification process, primary physicochemical precipitation, AO process, secondary physicochemical precipitation and biological aerated filter, thus, the water quality index of effluent can stably reach the water pollutant discharge standards for tanning and fur processing industries (GB30486-2013). The pre-aeration desulfurization and denitrification process can effectively remove NH3-N and S2- from wastewater and reduce the biological toxicity of wastewater.
