( 2 ) quantitively studied the solidification effect of different organic matter content silt , make clear the relationship of organic matter content and solidification effect ( 2 )定量的研究有機質(zhì)含量不同的淤泥固化效果,明確了有機質(zhì)含量與淤泥固化效果之間的關(guān)系。
Among dredged sediments , quite a portion come from polluted lakes and rivers , because such polluted sediments usually contain some organic matters . although the content of organic matters are much less than silt , but it seriously affected silt solidification effect , and this is a new subject in silt solidification research 固化技術(shù)是疏浚淤泥資源化利用的一個重要途徑,但是在疏浚淤泥當(dāng)中,有相當(dāng)一部分淤泥來自污染嚴(yán)重湖泊、河道,這些污染嚴(yán)重的淤泥當(dāng)中含有一定量的有機質(zhì),這些有機質(zhì)會對固化效果產(chǎn)生較大的影響。
( 4 ) as to different organic silt , make use of cement - gypsum compound material as solidification additives for silt solidification , comparatively studied the solidification effect , summarized the improving rule of gypsum to cement and proposed a method for treating high organic matter content silt ( 4 )對不同有機質(zhì)淤泥,采用水泥?石膏進復(fù)合型固化材料進行固化,對固化效果進行了對比研究,對石膏促進固化效果的規(guī)律進行了總結(jié),從而提出了大量發(fā)生的有機質(zhì)含量偏高的疏浚淤泥固化問題。
The main works of this paper are as follows : ( 1 ) studied two different organic content silt wuxi wulihu silt and shenzhen dayawan silt through single material ( cement ) solidification experiments . compared the solidification effect of the two silt , through the experiments conferred that organic matter remarkable affect cement solidification effect 本文的主要工作如下: ( 1 )對于有機質(zhì)含量明顯不同的無錫五里湖淤泥與深圳大亞灣淤泥進行了單一水泥的固化試驗,對固化效果進行了比較,指出有機質(zhì)會對淤泥的固化有效有顯著的影響。
In this paper , the influence of organic matter content on silt solidification effect was focused on . through laboratory experiments , studied the influence causing and degree of organic matter affect silt solidification . disclosed the relationship of organic matter content and solidification effect , and proposed a method for high organic silt disposing 本文首先通過室內(nèi)試驗研究有機質(zhì)對淤泥固化效果的影響,建立有機質(zhì)含量和固化效果之間的定量關(guān)系,初步揭示了有機質(zhì)含量對淤泥固化效果影響的機理,并通過采用復(fù)合型固化材料技術(shù)進一步解決了有機質(zhì)含量較高的疏浚淤泥應(yīng)當(dāng)如何固化的問題。
