摘　　要：采用PVA生物处理工艺在常温(12~17℃)条件下对某高校生活污水(ρ(CODCr)=130~330 mg/L,ρ(NH_3-N)=32~65 mg/L)进行处理。结果表明,PVA生物处理工艺运行负荷为1.5 kg[CODCr]/(m3·d)时,连续运行11 d,出水平均CODCr和NH_3-N的质量浓度分别为55.6和7.32 mg/L;此时整个处理系统污泥产率仅为0.1 g[MLSS]/g[CODremoved],无污泥外排。这说明扩大系统体积1倍,PVA生物处理工艺可以在常温下对生活污水进行有效处理。PVA biological process was used to treat domestic sewage （ρ （CODcr） = 130 - 330 mg/L, ρ （NH3-N） = 32 - 65 mg/L） from an university at normal temperature（ 12 - 17 ℃）. The results showed that, during a 11-day continuous operation with volume loading rates of 1.5 kg[CODcr]/（m3-d）, the mass concentrations of CODcr and NH3-N were 55.6 and 7.32 mg/L respectively, the sludge yield was 0.1 g[MLSS]/g[COD removed], and no sludge was discharged from the system. In conclusion, PVA biological process can effectively deal with domestic sewage by expanding the system volume double in normal temperature.
