River channel endogenous treatment method
The invention belongs to the technical field of river channel ecological management, and particularly relates to a river channel endogenous management method which comprises the following steps: when H1 is greater than or equal to H2, dredging polluted bottom mud by adopting an ectopic environment-friendly dredging mode, and dredging bottom mud of a normal layer by adopting a common dredging mode; when H1 is larger than or equal to H2-N and smaller than H2, dredging the polluted bottom mud in an ectopic environment-friendly dredging mode, and after dredging to the designed bottom elevation H1 of the polluted bottom mud, backfilling to the designed bottom elevation H2 of ecological restoration by adopting a backfilling material; and when H1 is smaller than H2-N, dredging the polluted bottom mud by adopting an ectopic environment-friendly dredging mode, after dredging to the ecological restoration bottom elevation H2-N, backfilling by adopting a backfilling material with the thickness of 0.2-0.3 m, and paving natural gravels on the backfilling material to the ecological restoration design bottom elevation H2. The invention provides a river channel endogenous treatment method adopting different treatment principles according to different pollution depths.
本发明属于河道生态治理技术领域，尤其涉及一种河道内源治理方法，所述河道内源治理方法包括以下步骤：H1≥H2时，采用异位环保疏浚方式疏挖污染底泥，采用普通的疏浚方式疏挖正常层底泥；H2‑N≤H1＜H2时，采用异位环保疏浚方式疏挖污染底泥，疏挖至污染底泥设计底高程H1后，采用回填材料回填至生态修复设计底高程H2；H1＜H2‑N时，采用异位环保疏浚方式疏挖污染底泥，疏挖至生态修复底高程H2‑N后，采用回填材料回填厚度0.2～0.3m，其上铺设天然砾石，铺至生态修复设计底高程H2。本发明提供一种根据污染深度不同采用不同的治理原则的河道内源治理方法。
