SBR工艺处理模拟酱油废水及混凝脱色研究
|
摘要
酱油废水中含有大量有机物,废水中COD和色度很高,本实验用SBR工艺去除模拟酱油废水中的COD和氨氮,并用混凝工艺去除色度,实验表明,在pH为7,曝气3 h时,COD的去除率达到86.9%,随着时间的延长,COD与氨氮的去除率分别达到94.9%、83.7%.SBR出水用混凝工艺去除色度,色度可降到40倍左右.
Soy sauce wastewater contains a lot of organic matters.COD and color are very high in wastewater.In this paper,the SBR process was used to remove the COD and color of simulated soy sauce wastewater.It was concluded that,when pH was 7,and the aeration time was 3 h,and the removal rate of COD was 86.9%.With the increase of the initial COD,the effluent COD was increased,and the removal rate was decreased.When the effluent wastewater was treated with PAC and Ga(OH)_2,the color can be reduced to about 40 times,reaching the two level of sewage discharge standard.
