摘要
[目的]探讨颤蚓污泥减量效果的影响因素。[方法]通过批次试验,考察了颤蚓对不同来源、不同浓度活性污泥的减量效果。[结果]MLVSS/MLSS值是影响颤蚓污泥减量效果的重要因素。对于不同污泥浓度的活性污泥,颤蚓的污泥减量效果存在明显差别,高污泥浓度下颤蚓的污泥减量效果更加明显,Y值与初始MLVSS值有较好的线性关系。[结论]为颤蚓污泥减量化的实际应用提供了理论依据。
[Objective] The aim was to explore influencing factors for sludge reduction induced by Tubificidae.[Method] According to different sources and different sludge concentration of the activated sludge,effects of sludge reduction induced by Tubificidae were investigated through the batch experimental.[Result] The MLVSS/MLSS value was one key factor affecting the sludge reduction induced by Tubificidae.Significant differences on sludge reduction induced by Tubificidae in different sludge concentrations of activated sludge,and more apparent in high sludge concentration,it had a good linear relationship with the value of Y and initial MLVSS.[Conclusion] The research provides theoretical basis for the practical application of sludge reduction induced by Tubificidae.
