摘　　要：水蚯蚓原位消解污泥技术是一种重要的污泥减量技术,其利用水蚯蚓和微生物的协同作用消解污泥,可从源头控制污泥产生。考察了环境因子、工况条件、污泥性状和水蚯蚓自身活动等方面对该技术的影响,结果表明,工艺的调整与优化能创造出宜于水蚯蚓原位消解污泥的优良条件,在保证污水达标排放的前提下,污泥减排率达到64.5%～81.7%;此外,水蚯蚓原位消解污泥技术对不同污水处理工艺均具有很好的适用性。As an important sludge reduction technology, in-situ Tubifex sewage sludge digestion technology can reduce sludge production at the source through the synergistic effect between Tubifex and microorganisms. The influences of environmental factors, operation conditions, sludge characteristics and Tubifex activity on the technology were investigated. The results show that an appropriate condition for insitu Tubifex sewage sludge digestion can be created by adjustment and optimization of the process. The sludge reduction rate reaches 64.5% to 81.7% when the wastewater discharge standard is met. Furthermore, the in-situ Tubifex sewage sludge digestion technology is well applicable for wastewater treatment in various areas.
