The invention belongs to the technical field of sludge treatment, and particularly relates to a riverway sludge resource utilization treatment method which comprises the following steps: S1, riverway desilting: desilting a small river with a shallow water level and a small sludge amount by adopting a first desilting mode, and desilting medium and large rivers and lakes with a deep water level and a large desilting amount by adopting a second desilting mode; and S2, garbage separation: pumping the river sludge dredged in the S1 into a garbage separation system to separate mixed sand and garbage so as to ensure the purity of the sludge. According to the method, the garbage separation step is added, gravel and garbage mixed in sludge can be separated before dehydration and solidification, the purity of the sludge is guaranteed, follow-up road backfilling operation is facilitated, and follow-up multi-aspect utilization is facilitated; by adding the conditioning reaction step, harmless treatments such as sterilization, disinfection, deodorization and removal of toxic heavy metals can be carried out on the sludge before dehydration and consolidation, the treatment quality is improved, and the safety of subsequent use is ensured.
本发明属于淤泥治理技术领域，尤其是一种河道淤泥资源化利用处理方法，包括以下步骤：S1：河道清淤：采用第一种清淤方式对水位浅和淤泥量小的小型河流进行清淤，采用第二种清淤方式对水位深和清淤量大的中、大型河湖进行清淤；S2：垃圾分离：将S1中清淤出来的河道淤泥泵送至垃圾分离系统内将混入的砂石和垃圾进行分离而保证淤泥的纯度。本发明通过增加了垃圾分离步骤，能在脱水固结之前将淤泥中混入的砂石和垃圾进行分离而保证淤泥的纯度，有利于后续的道路回填作业，有利于后续的多方面利用；通过增加了调理反应步骤，能在脱水固结之前对淤泥进行消菌杀毒除臭以及去除有毒重金属等无害化处理，提高处理质量，保证了后续使用的安全性。
