| 摘 要： | 采用序批式活性污泥反应器试验研究了解偶联剂2,4-二氯酚(DCP)的污泥减量化效果。试验结果表明:随着DCP浓度的增加,污泥比耗氧速率(SOUR)增加,污泥产率下降;相对底物比降解速率(q/q0)和相对污泥比增长速率(μ/0μ)随DCP浓度变化曲线分离程度增加;1～5mg/LDCP能有效地减少剩余污泥产量,而不影响污水处理效果;解偶联模型能有效模拟解偶联剂浓度对污泥表观产率的影响。

| Abstract: | The effect of excess sludge reduction by uncoupler of 2,4-dechlorophenol(DCP) was studied using Sequencing Batch Reactor.The results of the test showed that: with the increasing of the concentration of DCP,the specific oxygen uptake rate(SOUR) increased and the biomass yield of sludge decreased;The separation degree of the curves reflected the relative specific degradation rate of substrate(q/q0) and the relative specific growth rate of sludge(μ/μ0) increased with the varying of the concentration of DCP;DCP ranged from 1 mg/L to 5 mg/L could effectively reduce the biomass yield of excess sludge without influencing the wastewater treatment effect;uncoupling model was able to simulate the effect of the concentration of uncoupler on the observed yield of sludge. |
