【摘要】：隨著我國(guó)城市化進(jìn)程的加快和工業(yè)化程度的提高,污水處理廠的規(guī)模不斷擴(kuò)大,數(shù)量與日俱增,處理程度也不斷提高,進(jìn)而使得城鎮(zhèn)污泥總量年年攀升。填埋場(chǎng)為充分利用空間,一般采用在一層污泥上覆蓋一層土,然后進(jìn)行層層碾壓。但是在碾壓的過(guò)程中,因?yàn)槲勰嗑哂懈吆�、高粘度的特�?所以經(jīng)常使得碾壓機(jī)械打滑甚至深陷其中,給填埋操作帶來(lái)困難。同時(shí),碾壓而成的填埋體也因?yàn)槲勰嗟牧髯冃远兊脴O易變性和滑坡,帶來(lái)了極大的安全隱患。由于污泥細(xì)小,經(jīng)常堵塞滲濾液收集系統(tǒng)和排水管,再加上填埋場(chǎng)濾液處理量的大大增加,加重了垃圾壩的承載負(fù)荷,且清理收集系統(tǒng)的費(fèi)用極為昂貴,增加了成本。因此,用填埋的方法處理城市污泥已越來(lái)越不適應(yīng)經(jīng)濟(jì)、社會(huì)和環(huán)境發(fā)展的要求。用更科學(xué)、更有效的方法對(duì)污泥進(jìn)行無(wú)害化處理和資源化利用顯得日益突出,迫在眉睫。為了能夠更好的研究現(xiàn)行污泥的合理處置方法,對(duì)處理城市污泥做出貢獻(xiàn),選擇這個(gè)課題進(jìn)行相關(guān)的研究。本論文的研究首先收集了關(guān)于污泥摻燒技術(shù)的大量資料,介紹了污泥摻燒技術(shù)的相關(guān)理論,以及污泥摻燒技術(shù)的最新動(dòng)態(tài),分析了該技術(shù)相較于其他技術(shù)的優(yōu)勢(shì),然后結(jié)合金山熱電供電的具體情況進(jìn)行相關(guān)案例分析,再結(jié)合綜合評(píng)價(jià)的方法,得出污泥摻燒技術(shù)應(yīng)用及效果評(píng)價(jià)的成果總結(jié)。各章節(jié)的內(nèi)容如下。第一章提出了文章的研究背景及意義,國(guó)內(nèi)外的研究現(xiàn)狀,從研究的進(jìn)程中發(fā)現(xiàn)當(dāng)前污泥處理技術(shù)選擇污泥摻燒技術(shù)的必然性;第二章為介紹污泥摻燒技術(shù)的簡(jiǎn)單概念及幾種常用的項(xiàng)目評(píng)價(jià)方法;第三章介紹了金山熱電公司污泥摻燒技術(shù)的相關(guān)方案等內(nèi)容并對(duì)其進(jìn)行綜合評(píng)價(jià)指標(biāo)體系的構(gòu)建;第四章從項(xiàng)目過(guò)程指標(biāo),技術(shù)性能,財(cái)務(wù)狀況,國(guó)民經(jīng)濟(jì)這幾個(gè)方面對(duì)金山熱電公司污泥摻燒技術(shù)的實(shí)施效果進(jìn)行介紹;第五章通過(guò)模糊評(píng)價(jià)法和總體成功度評(píng)價(jià)對(duì)金山熱電公司污泥摻燒技術(shù)的實(shí)施效果進(jìn)行綜合評(píng)價(jià)。最后一章則提出對(duì)污泥摻燒技術(shù)進(jìn)行綜合評(píng)價(jià)后得出的建議與展望。本論文通過(guò)構(gòu)建污泥摻燒技術(shù)項(xiàng)目綜合評(píng)價(jià)的指標(biāo)體系,運(yùn)用模糊綜合評(píng)價(jià)法以及項(xiàng)目成功度評(píng)價(jià)方法對(duì)金山熱電公司污泥摻燒技術(shù)項(xiàng)目進(jìn)行綜合評(píng)價(jià),找出污泥摻燒技術(shù)實(shí)施的成功之處與存在的問(wèn)題,這將為以后的污泥摻燒技術(shù)的相關(guān)工程提供借鑒意義。
[Abstract]:With the acceleration of urbanization and the improvement of industrialization in China, the scale of sewage treatment plants is expanding, the number of wastewater treatment plants is increasing, and the degree of treatment is also increasing. In order to make full use of the space, the landfill usually covers a layer of sludge with a layer of soil and compacts it layer by layer. However, in the process of rolling, because the sludge has high moisture content, Because of its high viscosity, it often causes rolling machinery to slip or even sink into it, which makes the landfill operation difficult. At the same time, the compacted landfills become extremely volatile and landslide because of the rheology of sludge. Because the sludge is small, the leachate collection system and drainage pipe are often blocked, and the treatment capacity of the landfill filtrate is greatly increased, which increases the load of the refuse dam. And the cost of cleaning up the collection system is extremely expensive, which increases the cost. As a result, landfill treatment of urban sludge has become less and less suited to the requirements of economic, social and environmental development. More effective methods for the harmless treatment and reuse of sludge are becoming increasingly prominent and urgent. In order to better study the reasonable disposal methods of sludge and make contribution to the treatment of municipal sludge, This paper first collected a large amount of data on sludge blending technology, introduced the relevant theory of sludge blending technology, and the latest development of sludge blending technology. This paper analyzes the advantages of this technology compared with other technologies, and then combines the specific situation of Jinshan thermoelectric power supply to carry on the relevant case analysis, and then combines the comprehensive evaluation method. The results of application and effect evaluation of sludge blending technology are summarized. The contents of each chapter are as follows. The first chapter puts forward the research background and significance of the article, the current research situation at home and abroad, The necessity of selecting sludge blending technology for sludge treatment technology is found from the research process. Chapter two introduces the simple concept of sludge blending technology and several commonly used project evaluation methods. The third chapter introduces the related schemes of sludge blending technology in Jinshan Thermal Power Company and the construction of comprehensive evaluation index system. Chapter 4th from the project process indicators, technical performance, financial situation, This paper introduces the effect of mixed sludge burning technology in Jinshan Thermal Power Company from these aspects of national economy. Chapter 5th gives a comprehensive evaluation of the effect of sludge blending technology in Jinshan Thermal Power Company by fuzzy evaluation and overall success evaluation. The last chapter puts forward some suggestions and suggestions after comprehensive evaluation of sludge blending technology. In this paper, the comprehensive evaluation index system of sludge blending technology project is constructed. The fuzzy comprehensive evaluation method and the project success evaluation method are used to evaluate the project of sludge blending technology in Jinshan Thermal Power Company, and the success and problems of the implementation of sludge blending technology are found out. This will provide reference for the related projects of sludge blending technology in the future.
