Construction waste treatment method

The invention relates to the technical field of environmental protection engineering, in particular to a construction waste treatment method which comprises the following steps: S1, directly or indirectly identifying waste types according to the source and appearance characterization of construction waste; s2, screening and separating the miscellaneous construction waste, and separating soil, organic matters, magnetic substances and non-magnetic substances in the waste; s3, repeatedly crushing and screening aggregate separated from the miscellaneous construction waste and pure construction waste; and S4, separating light substances and mud powder in the fine recycled aggregate to obtain the treated recycled aggregate. Through a multi-layer classification treatment method, different wastes can be prevented from being mixed together, the post-treatment efficiency is effectively improved, the recycling work of the renewable aggregates is completed, and the influence of the construction wastes on the environment
