SBR法处理餐饮废水的工艺实验研究

Study On the Catering Trade Wastewater Treatment by Using SBR Process

采用序批式活性污泥法(SBR)工艺处理餐饮废水,实验考察了污泥浓度、污泥负荷与处理效果的关系以及该工艺的脱氮性能。结果表明,在COD_(Cr)负荷小于0.81kg/kg(SS)·d、油负荷小于0.112kg/kg(SS)·d的条件下,能使出水水质达到(GB8978-1996)二级排放标准。SBR工艺对于间歇排放的水质、水量变化较大的餐饮废水是一种理想的工艺选择。

When the CODCr load was less than 0.81kg/kg(SS)-d and the oil load was less than 0.112 kg/kg(SS)-d, catering trade wastewater could be treated to meet with the second grade standard (GB8978-1996) by using sequencing batch reactor (SBR) process. Through studying the relationship between the treatment effects and the concentration of the sludge, load of the sludge, and the capability of eliminating nitrogen, the SBR process is effective for treating catering trade wastewater with the characteristics of interim outlet and changing variety.
