The invention provides an environmental-friendly sludge reduction system and a method. The environmental-friendly sludge reduction system and the method are used for solving problems that sludge producing amount is large, and offensive odor is generated in sludge storage process. The environmental-friendly sludge reduction system comprises a peroxy aeration tank, a sterilization device, a hydrolysis-acidification pool, an aerobic aeration tank, a sludge sedimentation basin, a sludge deodorizing device, and a dehydration device. In sludge reduction processing process, generation of stink is inhibited fundamentally, and no stink is generated by sludge after sludge reduction processing. 本发明提供种环境友好型污泥减量系统及方法，针对污泥产量大，且污泥放置产生恶臭的问题，包括过氧曝气池、灭菌装置、水解酸化池、好氧曝气池、污泥沉淀池、污泥除臭装置、脱水装置，在污泥减量处理过程中，从根本上抑制臭气的产生，且减量后的污泥也不再产生臭气。
