摘要
采用单纯好氧消化和生物促生好氧消化对污泥减量及CODCr降解进行对比分析。结果表明:经过38 d的好氧消化,污泥量最终从16.02 g/L下降到7.48 g/L,污泥去除率已大于50%,污泥去除率呈上升趋势最终达到53.3%;CODcr由60 mg/L降低到43.6 mg/L,接近城镇污水处理厂一级排放标准。使用生物促生技术后,反应6 d,MLSS由12.34 g/L迅速降低到6.12 g/L,污泥浓度已降至50%以下,其去除率迅速上升达到50.41%;CODCr由60 mg/L降低到32.6 mg/L,达到并优于城镇污水处理厂一级排放标准。
The paper analyzed the sludge reduction and CODer degradation with the aerobic and anaerobic digestion begot biological way separately. The result showed： after 38 days of aerobic, sludge quantity eventually fell from 16.02 g/L to 7.48 g/L. More than 50 % sludge had been removed and the rate of sludge reduction eventually reaches 53.3 %. CODer reduced from 60 mg/L to 43.6 mg/L, close to the urban sewage discharge standard level. After six days MLSS reduced from 12.34 g/L to 6.12 g/L quickly with biological biostimulation and sludge concentration had been reduced to less than 50 %. The rate of sludge removal rapid rises to 50.41% and CODcr reduced from 60 mg/L to 32.6 mg/L, reachin~ the sewa^ze discharge standard level.
