摘　　要：针对环保疏浚余水处理的复杂性与必要性,本研究采用物理、生物、化学综合处理方法,使疏浚余水依次通过生物排泥池、沉淀池、澄清池,并利用一体化加药设备向余水均匀投加聚合氯化铝(PAC)絮凝剂,经处理的余水排放水质达到《污水综合排放标准》(GB 8978-1996)二级标准,表明本研究运用的余水处理方法效果明显,实现了疏浚余水达标排放和环保疏浚的连续吹填。Pointed to the complexity and necessity of residual water treatment from environmental dredging,the paper took a comprehensive method for residual water treatment,using biological,physical and chemical methods,let the residual water pass through biological sludge tank,settling tank and clarification tank.Poly-aluminium chloride flocculants were uniformly added in residual water by using the integral drug-feeding equipment.The water quality of the treated residual water can reach the second grade of Integrated Wastewater Discharge Standard(GB 8978-1996).The results show that the method for residual water treatment is effective.The method can ensure the residual water to meet the effluent standard and the environmental dredging project to continuously dredge at the same time.
