雨污管道淤泥一体化处理系统的设计

Design of Integrated Treatment System for Sludge from Rain Sewage Pipeline

摘要: 本文通过将垃圾分拣、沙石分离、淤泥稳定化无害化、淤泥脱水、余水净化等这些环节集中于一体，设计了雨污管道淤泥一体化处理系统，目标是提高处理淤泥的效率。淤泥的调理药剂成分和用量根据淤泥特性而定，调理后经初步脱水的含水率从98.9%降到62.46%。系统的机械压滤脱水结构，采取了水平、弧形、S形三步逐步压榨的方式，淤泥脱水单元模块包括搅拌入料模块、浓缩模块和脱水模块，对初压的淤泥进行深度脱水时，含水率可以再降低10个百分点以上，约50%。

Abstract: The design of integrated treatment system for sludge from rain sewage pipeline was made by concentrating the garbage sorting, sand separation, sludge stabilization harmless, sludge dehydration and the residual water purification in one. This design was to improve the efficiency of sludge treatment. The composition and dosage of conditioning agents for the sludge were determined according to the characteristics of sludge. After conditioning, the water content of primary dehydration was reduced from 98.9% to 62.46%. The mechanical pressure filtration dehydration structure of the system used three-step press of the horizontal, curved and S-shaped. The sludge dehydration unit module included the stirring feed module, the enrichment module and the dehydration module. When the initial pressure sludge was deeply dehydrated, the water content could be reduced by more than 10 percentage points, which was about 50%.
