Novel comprehensive treatment and ecological restoration technology for river sludge
The invention provides a novel comprehensive treatment and ecological restoration technology for river sludge, and relates to the technical field of river ecological treatment. The technology comprises the steps of stopping a river; settling the sludge; pumping out river water and whitening sludge; performing high-temperature fire spraying burning on sludge, wherein the sludge does not need to be pumped out or dug out from the bottom of a river channel, the water environment cannot be damaged, organic fertilizer is mixed and stirred after being washed with cold water, the organic fertilizer comprises fertile soil, ceramsite sand, coal cinder, biological sand and organic sand, and the sludge containing a small amount of organic matter is converted into the organic fertilizer rich in nutrients; promoting growth of aquatic plants, and improvement of the treatment effect and increasing the ecological restoration speed; removing the dam and discharging water, and adding microbial flora for the second time for sludge activation treatment; submerged plants are planted at the bottom of the river channel, and aquatic animals and microorganisms are stocked in water. The treatment method has the advantages of high efficiency, environmental protection, resource saving and the like, and is beneficial to continuous restoration of river ecology.
本发明提供了一种新型河道淤泥综合治理生态修复技术，涉及河道生态治理技术领域，包括对河道进行截流；淤泥沉降处理；抽出河水并将淤泥晒白；对淤泥进行高温火喷烧，无需将淤泥从河道底部抽出或挖出，不会对水体环境造成破坏，冷水冲刷后混入有机肥料进行搅拌，有机肥料包括肥沃土，陶粒砂，煤渣，生物沙和有机沙，使含少量有机物的淤泥转变为富含养分的有机肥，促进水生植物的生长，有助于提高治理效果和生态修复速度；拆坝放水并二次投入微生物菌进行淤泥激活处理；在河道底部种植沉水植物，并在水中上放养水生动物和微生物。本治理方法高效、环保、节约资源等诸多优点，有益于河道生态的持续性修复。
