中文摘要:
      颗粒污泥形成受多种因素的影响,通过在流体中添加适量剂量的絮凝剂,利用流体力化学-二次流原理,施加合适的流体剪切力,形成合理的二次流场,可以在很短的时间内形成原始颗粒污泥.利用污泥内部和水中的微生物,通过好气或厌气培养,能加快(好氧或厌氧)颗粒污泥的形成,是加快颗粒污泥培养的有效途径,在污水处理生产应用中具有广阔的前景.
英文摘要:
      Granular sludge forming can be affected by many factors.Reasonable Secondary Flow will be formed to get original granular sludge in a short time through adding some flocculant dosage in water and putting right flow shear force by use of Hydrodynamics-Physical Chemistry and Secondary Flow Theory.Granular sludge(aerobic or anatrobic)can be formed fleetly by cultivating microbes with aerobic or anaerobic condition in sludge and water.It is an effective approach to expedite granular sludge forming which has a wide foregrormd in wastewater treatment.
