摘　　要：主要利用生物接触氧化工艺对模拟船舶生活污水的处理进行了中试。结果表明,在HRT=3.5 h,T=25～30℃,pH=6.8±0.5条件下,当进水CODCr,BOD5,SS,NH4＋^-N平均浓度为597.8 mg/L,371.8 mg/L,369 mg/L,33.52 mg/L时,出水平均浓度为90.0 mg/L,38.5 mg/L,59 mg/L,4.66 mg/L,平均去除率分别达到85.0%,89.6%,83.9%以及86.0%。试验表明该工艺对船舶生活污水有良好的去除效果,可以满足实际应用的需要。In this paper, pilot-scale test of biological contact oxidation process for simulated ship sewage treatment was carried out. The results showed that under the condition of HRT = 3.5 h, T = 25 - 30 ℃, pH =6. 8＋0. 5, and the average concentrations of CODcr, BODs, SS and NH4^＋ - N in the influent were 597.8 mg/L, 371.8 mg/L, 369 mg/L and 33.52mg/L, respectively, the concentrations of CODcr, BOD5, SS, NH4^＋- N in the effluent were 90. 0 mg/L, 38.5 mg/L, 59 mg/L, 4. 66 mg/L, and the average removal rates of CODcr, BOD5, SS, NH4^＋- N were 85.0%, 89.6%, 83.9% and 86. 0% , respectively. The results indicated that biological contact oxidation process had good effects on ship sewage treatment and can meet the needs of practical application.
