Special Study on Sediment Dredging and Disposal for Suzhou River Project Phase Ⅳ
The ecological soil pipe bag process is firstly used in the sediment disposal in Shanghai.Before the new process actually applied in engineering,the special research and preliminary experiments are conducted in pilot work to verify its reliability,effectiveness and economy in order to reduce the decision-making risks.Combined with the sediment characters of Suzhou River,the chemical composition ratio of dehydration additives is tested and then improved.The ecological soil pipe bag process reduces the activity of heavy metals in the sediment of Suzhou River after disposed in order to achieve the fixation and stability of heavy metals in sediment and reduce the soil leaching toxicity.
