River channel dredging method
The invention discloses a riverway desilting method which comprises the following steps: S1, pretreatment, S2, chemical treatment, S3, biological treatment and S4, aftertreatment, wherein a chemical reagent is used for chelating heavy metal bottom mud through an optimizer, so that secondary pollution of the bottom mud is effectively avoided; the compound microbial agent is capable of effectively degrading organic matters in river sludge by virtue of photosynthetic bacteria, lactic acid bacteria and saccharomycetes through reasonably matching strains and enhancing a synergistic relationship among the strains, and is combined with chemical cleaning, so that the balance of microbial communities in a river water body is effectively improved; compared with an existing chemical and biological combined desilting mode, the problems of secondary pollution of heavy metal bottom mud and substandard tail water are effectively avoided.
本发明公开了一种河道清淤方法，包括如下步骤：S1，预处理，S2，化学处理，S3，生物处理，S4，后处理，其中化学试剂通过优化剂对重金属底泥进行螯合，有效避免底泥的二次污染；而复合微生物菌剂通过合理搭配菌种，增强菌种间协同关系，光合细菌与乳酸菌、酵母菌能对河道淤泥有机物有效降解，结合化学清理，有效改善河道水体微生物群落平衡；相比现有的化学生物结合清淤方式，有效避免了重金属底泥的二次污染和尾水不达标的问题。
