Method for applying dehydrated eutrophicated polluted bottom mud geotextile pipe bags to ecological bank protection
The invention provides a method for applying dehydrated eutrophicated polluted bottom mud geotextile pipe bags to ecological bank protection. The method comprises the following steps that: (1) a dehydration field is trimmed along the boundary of a sewage containing pit or the bank of a river and a lake, and an impermeable layer is additionally paved on the dehydration field; (2) geotextile pipe bags are laid on a side slope; (3) the bottom mud of the sewage containing pit or river and lake is conveyed into a closed pipeline through a mud pump, the water content of the dredged bottom mud is about 90%; (4) the bottom mud conveying pipeline is closed, a dosing system is arranged on the conveying pipeline, and the obtained eutrophicated polluted bottom mud is conveyed into a geotextile pipe bag in a closed mode through the mud conveying pipeline; (5) the bottom mud is dewatered and solidified for 30-50 days after the geotextile pipe bag is filled with the bottom mud, the water content is lower than 50% after the bottom mud is dewatered and solidified; and (6) after the dewatering and volume reduction of the bottom mud are completed, a layer of planting soil with the thickness of 500-1000 mm is laid on the bottom mud, and ecological greening is conducted on a revetment. The method is simple, safe, energy-saving and environment-friendly; the moisture content of the treated bottom mudis low; and environment-friendly dredging and ecological bank protection are effectively combined together.
本发明提供一种富营养化污染底泥土工管袋脱水后用于生态护岸的方法，包括：(1)沿纳污坑塘边界或河流湖泊堤岸修整出脱水场地，在脱水场地上加铺防渗层；(2)在边坡上铺设土工管袋；(3)通过泥浆泵将纳污坑塘或河流湖泊的底泥输送至封闭管路中，疏浚的底泥含水率为90％左右；(4)底泥输送管路为封闭式，在输送管路上设置加药系统，所得富营养化污染底泥经输泥管路密闭输送到土工管袋中；(5)土工管袋填充完毕后脱水固结30‑50天，底泥脱水固结完成后含水率低于50％；(6)底泥脱水减容完成后，在其上铺垫一层500‑1000mm厚的种植土，对护岸进行生态绿化。该方法简单、安全、节能、环保，处理后底泥含水率低，将环保清淤与生态护岸有效结合在一起。
