River sediment in-situ soil ecological restoration method
The invention discloses a riverway sediment in-situ soil ecological restoration method which comprises the following steps: digging at least one oxidation ditch on two sides of a riverway to be treated, laying sediment meeting fermentation conditions in the oxidation ditch, adding an organic conditioner, microorganisms, a passivator and soil before fermentation to improve the sediment property, promoting aerobic fermentation of a pile body, and removing odor and peculiar smell in the sediment. The toxicity of heavy metals in the bottom mud is reduced, the bottom mud can be converted into soil rich in humus through aerobic fermentation, the problem of endogenous pollution of a river channel is solved, the bottom mud can be used for planting green plants and fixing soil and reinforcing a dike, meanwhile, rich fertility is provided, and good ecological benefits are achieved.
本发明公开了一种河道底泥原址土壤化生态修复方法，包括在待处理河道两侧挖至少一氧化沟，将达到发酵条件的底泥铺设在氧化沟里，发酵前加入有机调理剂、微生物、钝化剂及土壤改善底泥性质，促进堆体好氧发酵，除去底泥中臭味、异味，并且降低了底泥中重金属毒性，经过好氧发酵，底泥可以转变成具有丰富腐殖质的土壤，既解决了河道内源污染问题，又可以用来种植绿植，固土护堤，同时提供丰富的肥力，具有良好的生态效益。
