水庫淤泥處理與去化－以石門水庫為例
The Processing and Elimination of Reservoir sludge – A Case Study on Shihmen Reservoir.
摘要
我國水庫具規模者40餘座，每年產生淤積泥砂達1,460餘萬立方公尺，數量極為龐大，水庫淤泥本身即是礦土石，經處理後可替代礦區土石料源。開採水庫淤泥除符合政府土石多元開發利用政策外，同時可恢復水庫庫容，延續水庫壽命。 本研究經採樣並以DLS動態光散射儀，量測淤泥粒徑及粒子表面電荷分布結果，石門水庫淤泥質細(834nm~1547nm)，具膠體粒子不易沉降特性，表面電荷分布平均約-15~-20mV，顯示其帶電性，具離子吸附性能。另本研究自製吸水性樹脂(SAP)，其與淤泥混拌進行吸水實驗，實驗結果100g含水率70%之淤泥，加入約3.5g之吸水性樹脂，可於極短時間形成乾涸土壤，有利後續處理。 另經與業者、專家、學者、政府官員進行深度訪談，確認石門水庫淤泥再利用途徑相當多元，淤泥處理與去化的關鍵因素如下：穩定供應淤泥料源、政府提供誘因獎補助、將淤泥製品納入為公共工程指定材料、鼓勵民間專案申請浚渫及處理利用、管理單位事權統一，同時政府應重視資源化產業整體架構，結合各領域技術與科學再加以整合運用尤其整合性技術研發，應為推動重點。

The deposition of reservoir sediment is more than 14.6 million cubic meters per year in Taiwan. Reservoir sediment is itself mineral. After processing the reservoir sludge, it can be used as alternative material to apply in many industries. This is also meeting the diverse supply policy of government and recover reservoir capacity and extend life of reservoir. Some sludge taken from Shihmen Reservoir were tested in this study. The analysis, with the dynamic light scattering(DLS) instrument, showed that the sludge particle size is 834nm ~ 1547nm and particle surface charge distribution is -15 ~ -20mV, these tests display the sludge is a very tiny partical and with ion adsorption properties. This study also made a super-absorbent polymer (SAP) and mixed with 100g sludge (water content 70%), when adding about 3.5g of super-absorbent polymer, it is formed dry soil in a very short time, and it will be enable follow-up treatment. Another consultation with industry experts, academics, government officials, confirm Shimen Reservoir sludge recycling pathway is quite diverse, the key factors of elimination of reservoir sludge are as follows: a steady supply of sludge sources； government offers incentives to award；the sludge products are specified as public engineering materials；to encourage the private project of dredging and processing to apply；to integrate all of the management of governmen。
