Abstract

The invention discloses a method to reuse of two kinds waste hazardous materials in cement concrete. Fly- and scrubber-ash from a municipal solid waste incinerator (MSWI) were mixed uniformly in their production weight proportions, then, the mixture was added to the chemical mechanical polishing (CMP) sludge with the suitable weight ratios of ash-mix and melted to form a glassy slag(call MSWI-CMPS slag). The slag-blended cement mortar (SBCM) specimens were manufactured with 0, 5, 10, 20 and 30 wt. % of the cement replaced by slag powder, and the molded specimens were for compressive strength testing. The test result reveal the compressive strength of SBCM specimens were close to or higher than those of ordinary Portland cement mortar (OPCM) in early curing age (1-7 day), and were 7-21% higher than those of the OPCM specimens after curing ages of 14-90 days, the test results exhibit the Pozzolanic reaction induced good performance of strength evolution, it can be used as ordinary cement freely in construction engineering. This article also investigate the toxicity characteristic leaching procedure(TCLP) test of MSWI-CMPS slag, the setting time test and fluidity test of cement mortar. The test result depict the amount of leached heavy metals was far below the EPA'S regulatory threshold. Hence, the MSWI-CMPS slag could be partially replace cement in cement mortar, and the MSWI ash-mix and CMP sludge can be recycling as a resource potentially, and that is particularly environmentally friend and compatible with the demands of sustainable development.

Description of the invention: [Technical field to which the invention pertains] The present invention relates to a cement material, and more particularly to a recycled cement using waste industrial waste such as waste incineration mixed ash and chemical mechanical polishing sludge. Materials and their methods of regeneration. [Prior Art] Most of the urban waste in Taiwan is incinerated by waste incinerators. However, the fly ash and washing ash generated by the incineration plant contain a variety of heavy metals that are harmful to health, and are hazardous industrial wastes. Curing with chelating agents to avoid harm to the environment. At present, there are 24 garbage incineration plants operating in Taiwan. In 1989, the Environmental Protection Agency announced that the output of fly ash and washing ash is as high as 270,000 metric tons. Generally, fly ash and washing ash are solidified by cement. It is abandoned by the contractor to the commercial waste landfill, but the buried treatment may still have the risk of poisoning heavy metal dissolution [1]. In view of the fact that Taiwan is densely populated and the public opinion also has high requirements for environmental protection, the landfill is caused. It is increasingly difficult to set up, so the recycling of fly ash and washing ash has become an urgent issue for environmental protection and sustainable development. Also, the semiconductor industry of Sigma Bay is the world leader. Chemical mechanical polishing and wet pickling in the wafer manufacturing process of the semiconductor industry will produce chemical mechanical polishing sludge (CMP sludge) and hydrogen fluoride. Acid sludge (HF sludge), a mixture of the two is referred to as CMps sludge, which is also 201245103 hazardous waste; its research or invention of reprocessing or reuse has not been seen until recently. Because the sludge contains a variety of oxidants, additives, dispersants, grinding buffered organic and inorganic compounds, etc., which also contain nano-sized Si〇2, ΑΙΑ; and other micro-particles [2,3], especially si〇2 particles The particle size is smaller, and if it is not properly handled between 2〇~3〇〇nm, it is easy to cause damage to the ecological environment, and it is more likely to pose a threat to human health and needs to be properly handled. However, the current semiconductor park semiconductor manufacturing wafer processing and processing site has disposed of the CMps mixed sludge by the abandonment manufacturer. If any hidden crisis is buried, it cannot be ignored. The average age of 5 is that nano particles may injure the lungs with the inhalation of breathing. It may also cause damage to cells by wearing human skin into the body, lungs and digestive system. Moreover, the human body is generally immune to the lack of immunity to new substances and therefore may be unreactive to the toxicity of nanoparticles. Y & c 〇匕i et al. [4] experimented with the effect of 20~12〇nm* nanoparticles of the same type on the barrier properties of mouse alveolar epidermal cells, and the results showed that alveolar cells were caused by exposure to different nanoparticles. Epidermal cell barrier function varies to varying degrees. According to the study of Linetal·[5], artificially cultured lung bronchial epithelial cancer cells were treated with 15, 46 nm, . , and 2 particles; the ° 笞 ° test showed a dose-dependent cytotoxicity. Root: =1^11[6] of the research nine, with 4〇~5〇〇〇1^ diameter marked with fluorescent rice S1〇2 particles, the results of artificial culture of human epithelial cells are not: 40~ The 7〇nm camp light Si〇2 nanoparticle can cause the formation of heterogeneous protein aggregates in the nucleus, inhibiting replication, 201245103 =, Tianyue l% colonization. Moor [7] states that artificial nanoparticles are released from the aquatic %^ brother's path through cell intake, which may harm the cells and tissues of aquatic animals, and thus, screaming for donation and its health, or even causing ecological and human food chains. The crisis, therefore, for every new nanomaterial, Hu Yun needs a preventive treatment to assess its environmental health hazards. The research and application of the recycling of bottom ash in waste incineration plants has been effective. It can be applied to the road base material, fired red bricks and permeable bricks, and can also be used to burn tiles used in buildings. The resource recycling of waste incineration plant fly ash is still in the active development research stage. J. Pera, et al. [8] used the incineration bottom ash to screen the grain size between 4 mm and 20 mm to replace the coarse aggregate. The 28-day strength of concrete can reach 25 Mpa, even without a large replacement rate of 50%. Luca Bertolini, et al. [9] washed the fly ash with water to reduce its chlorine content and added 30% cement to the cement mortar sample by adding water ash and bottom ash dry grinding, respectively. The compressive strength of the wet-ground ash is higher than that of the standard test body, and the excellent wind-like reaction is exhibited.

Amer Ali-Rawas等人[1 〇]以垃圾焚化飛灰取代部分 水泥與取代部份砂進行水泥砂漿試體之研究,其取代 砂者坍度會變小,取代水泥者坍度會增加,且其28天 強度則相近或稍高。Lin等人[11]將都市垃圾焚化飛灰 熔融處理之熔渣粉末,分別以0%、1 〇%與20%之水泥 201245103 取代率灌鑄成2·54 cm x 2.54 cm x 2.54 cm水泥漿試 體,試驗結果顯示:試體28天抗壓強度為未取代者強 度之84%〜96%,試體9〇天抗壓強度為未取代者強度 之95%〜π〇%。其後,Lin等人[1213]再針對都市 垃圾焚化飛灰經熔融處理研磨成粉末,於取代部份水 泥製成水泥漿試體後,進行其水化作用之觀察與八丨2〇3 於水合活性之分析研究,均獲良好之成果,但其28天 以前之強度仍低於純水泥漿試體。Lin [14]將MSWi 飛灰熔渣粉末依10〜40 %比例,分別取代!型、〖丨型 之波特蘭水泥與Belite水泥,製成2.54 cm χ 2 M cm χ 2.54 cm水泥聚試體,其抗壓強度之成長與標準試體相 較其早期強度之增長較低,但晚期強度之增長則較 多。Lee等人[15,16]將飛灰熔渣粉末依1〇%〜4〇%比 例,取代I型波特蘭水泥製成5 cm x 5 cm χ 5 cm水泥 砂漿試體,其抗壓強度之成卩與標準試體相較,其Μ 天強度約為75〜89%,90天強度則為%〜1〇4%,確 與前述水泥漿試體之試驗結果相仿。其後,La等人 [1 7-20]再以添加玻璃粉或水玻璃集塵灰與Ms%〗混合 灰共融處理,其試驗成果似顯現垃圾焚化混合灰熔^ 用以取代部份水泥資源再㈣之可能性。惟其早期強 度(14天以前)不足之問題仍待克服;否則因灌之θ 凝土結構構件無法依一般營建工程之時間拆模,’對施 工之管理與安全將構成威脅,亦使1期增長而增加成 201245103Amer Ali-Rawas et al. [1 〇] replaced some cement with waste incineration fly ash and replaced some sand for the study of cement mortar samples. The degree of replacement of sand will be smaller, and the degree of replacement of cement will increase. Its 28-day intensity is similar or slightly higher. Lin et al. [11] poured the slag powder from the municipal waste incineration fly ash into a slurry of 2·54 cm x 2.54 cm x 2.54 cm with a substitution rate of 0%, 1% and 20% cement 201245103, respectively. The test results showed that the compressive strength of the test body was 84% to 96% of the strength of the unsubstituted person, and the compressive strength of the test body was 95% to π% of the strength of the unsubstituted person. Later, Lin et al. [1213] further processed the municipal waste incineration fly ash into a powder by melt treatment, and after replacing the part of the cement into a cement slurry test, the hydration observation and the gossip were carried out. The analysis of hydration activity has achieved good results, but its strength before 28 days is still lower than that of pure cement slurry. Lin [14] replaced MSWi fly ash slag powder with 10~40% ratio! Type, 丨 type Portland cement and Belite cement, made of 2.54 cm χ 2 M cm χ 2.54 cm cement poly-test body, the growth of compressive strength is lower than that of the standard test body. However, the increase in late intensity is more. Lee et al. [15,16] replaced the type I Portland cement with a 5 cm x 5 cm χ 5 cm cement mortar sample at a ratio of 1% to 4% by weight of fly ash slag powder, and its compressive strength. Compared with the standard test body, the enthalpy is about 75~89%, and the 90-day strength is %~1〇4%, which is similar to the test results of the cement slurry. Later, La et al. [1 7-20] added the glass powder or water glass dust ash and Ms% mixed ash co-fusion treatment, and the test results seemed to show that the garbage incineration mixed ash fusion was used to replace part of the cement. The possibility of resources (4). However, the problem of insufficient early strength (14 days ago) still needs to be overcome; otherwise, due to the fact that the θ concrete structural members cannot be demolished according to the time of the general construction project, 'the management and safety of the construction will pose a threat, and the first phase will also grow. And increase to 201245103

The MSWI mixed ash, CMP sludge and MSWI-CMPS slag powder obtained in this experiment were selected by micro-samples and observed by SEM scanning electron microscope. The MS WI mixed ash was agglomerated as shown in Figure 1. The CMP sludge is agglomerated in a spherical or pebbled shape with a particle size of approximately 200 nm to 6 μηι, as shown in Figure 2. The MS WI-CMPS slag powder particles are in the form of a crushed stone having a size of less than 38 μm, as shown in FIG. The chemical composition of the MSWI mixed ash, CMP sludge and MSWI-CMPS slag was then analyzed by EDS, as shown in Figures 1-3 and Table 1. The chemical composition of the MS WI-CMPS slag containing the non-calcium oxides SiO 2 , Al 2 〇 3 and Fe 203 was 24.33 to 49.16 ° / respectively. The sum of 9.16~16.48% and 0.92~1.52%' is 34.41~67.05%, but the CaO content is also as high as 23.30~45.18°/. Close to eight 8 □ 1 ^ € 618 regulations (: the content of grade fly ash 'non-calcium oxide is the main substance of the reaction of 201245103, and the more calcium oxides, there may be better reaction, that is, the strength It may be used in the early stage. XRD analysis: The MS WI mixed ash, CMP sludge and MS WI-CMPS slag are diffracted by X-ray powder, and the obtained analytical spectrum is shown in Figure 4. The most prominent phase material of ash is calcium, which are CaS04, CaCl2, CaClOH and Ca(OH)2, followed by K, Na, Pb, Zn and SiO2. Quenched and tempered mixed ash slag shell|J is amorphous phase The glassy material has a broad X-ray diffraction pattern and is characterized by a glassy substance, which is a typical material. TCLP dissolution test: Fly ash, washed ash and mixed ash all contain Pb, Zn, Cu Hazardous heavy metal components such as Cd and Cr are easily dissolved and contaminate groundwater. However, after high temperature melting treatment, they are surrounded by a network structure of -Si-O- to form a slag with dense, acid and alkali resistance and low dissolution rate effect. The MS WI-CMPS slag is non-crystalline by XRD analysis. The glassy substance will form a network of -Si-O- surrounded by heavy metals. Therefore, the results of TCLP dissolution test, the amount of Pb and Cd dissolved in MS WI mixed ash are higher than the values specified in US SW 846-131 1 specification. The amount of heavy metal dissolved in MSWI-CMPS slag is much lower than the values specified in the above regulations. The test results are shown in Table 4.

此現象已突破習知技術均有早期強度(1-28天)不足之 問題,依本發明該再生水泥材料製作之SBCM試體, 大部分SBCM試體於1 -90天之所有養護齡期,其抗壓 強度均高於OPCM試體,約高 2-21%,此表示 MSWI-CMPS熔渣替代部份水泥使用之優越性。 由上可知,本發明利用有害事業廢棄物為材料之 再生水泥材料及其再生方法可獲致至少以下之效果: (1 )本發明揭露一種將化學機械研磨污泥(CMPS ) 取代水泥,製成砂漿,養護後,此砂漿經毒性溶出實驗 (TCLP),無毒性物質溶出;且所得到的強度,在某些取代 範圍可以明顯高於一般水泥砂漿,具有顯著的新穎性。 (2 )本發明進一步揭露將化學機械研磨污泥與垃圾 焚化混合灰之共融熔渣取代部分水泥,所得到的砂漿養護 後總強化量可以高於純水泥砂漿試體,或僅用飛灰熔渣之 砂漿試體者;而且1天養護強度即可以跟一般水泥砂漿相 28 201245103 等或略高;其進步性非常明顯。 (3 )本發明可將垃圾焚化廠之飛灰與洗滌灰悉數處 理,其減容率高達73.5°/。,而可將有害環境的廢棄物,熔 融成炼〉查後才棄置而無害環境。故本發明具有良好綠色、 環保與永續發展之意義。 (4 )本發明再生水泥材料配成砂漿或混凝土,可成 為比一般水泥砂漿或混凝土更強上2〇%的建材,具有很大 的工程實用價值。 綜上所述’本發明將垃圾焚化廠所產生之有害事 業廢棄物飛灰與洗;條灰(亦稱反應灰或反應生成物)予 以悉數混合’再添加適量的半導體化學機械研磨製程 之廢污泥粉末,予以均勻混合後進行熔融處理所形成 之玻璃質熔潰具-Si-O-之網狀構造,能將殘留於熔渣晶 格中之重金屬予以包絡’致使重金屬不易溶出,俾可 取代部分水泥’與砂、水等調配成水泥砂漿,於取代 量5〜30°/。之範圍,養護強度可以高於純水泥砂漿,且 其流度值(施工軟度)較純水泥砂漿為佳,凝結時間則 相近。由抗壓強度之s式驗結果發現,此炼渣可以大幅 提升早期(1〜7天)之強度’因此炼潰砂衆試體之早期強 度大部分比純水泥砂漿為高,其餘部分試體則相仿, 而14〜90天齡期則均高於純水泥砂漿之強度,超出約 7〜21 % ’功效非常良好。又,該熔渣粉末經毒性特性 溶出试驗分析結果’其重金屬之溶出量遠低於環保署 29 201245103 規定之法規值。試驗結果顯現該溶渣可取代5〜30%水 泥使用,可作為環保水泥使用。基此,本發明可將垃 圾焚化廠之飛灰與洗滌灰全數予以資源化再利用,既 可減少飛灰、洗滌灰與化學機械研磨污泥掩埋場之需 求,亦利於防止上述有害事業廢棄物,於不適當棄置 時造成之環境污染,並可將這兩種廢棄物轉化成為水 泥使用,而無二次污染之疑慮。更可減少水泥製造所 產生之環境污染與破壞問題;緣是,本發明確實符合 發明專利之規定,爰依法提出申請。 【圖式簡單說明】 圖一:垃圾焚化混合灰之(a)SEM微觀影像與 (b)EDS成份分析圖。 圖二:CMP污泥之(a) SEM微觀影像與(b) EDS成 份分析圖。 圖三:MS WI-CMPS熔渣之(a) SEM微觀影像與(b) EDS成份分析圖。

OPCM) What percentage of the test is used. Looking at the growth of the cement mortar in the experimental group and the control group, only a small part of the experimental group had a slightly lower intensity than the control group at the first day of the test, and most of the other samples were compared. The control group is high. This phenomenon has broken through the problem that the prior art has insufficient early strength (1-28 days). According to the SBCM test piece made of the recycled cement material of the present invention, most of the SBCM test bodies are in the range of 1-90 days. At all curing ages, the compressive strength is higher than that of the OPCM specimen, which is about 2-21% higher. This indicates the superiority of MSWI-CMPS slag to replace some cement. It can be seen from the above that the regenerated cement material using the hazardous business waste as a material and the regeneration method thereof can at least achieve the following effects: (1) The present invention discloses that a chemical mechanical polishing sludge (CMPS) is used instead of cement to form a mortar. After curing, the mortar is subjected to toxic dissolution test (TCLP), and the non-toxic substance is dissolved; and the obtained strength can be significantly higher than the general cement mortar in some substitution ranges, and has remarkable novelty. (2) The present invention further discloses that the co-melting slag of the chemical mechanical grinding sludge and the garbage incineration mixed ash is substituted for part of the cement, and the total strengthening amount of the obtained mortar after curing can be higher than that of the pure cement mortar sample, or only the fly ash is used. The slag mortar tester; and the 1-day curing strength can be slightly higher than the general cement mortar phase 28 201245103; its progress is very obvious. (3) According to the present invention, the fly ash and the washing ash of the waste incineration plant can be processed in a complete manner, and the capacity reduction rate is as high as 73.5°/. The waste that is harmful to the environment can be melted into a refining and then discarded before being harmless. Therefore, the invention has the meaning of good green, environmental protection and sustainable development. (4) The recycled cement material of the present invention is formulated into mortar or concrete, which can be a building material which is 2% more than the general cement mortar or concrete, and has great engineering practical value. In summary, the invention relates to the waste ash and washing of the hazardous business waste generated by the waste incineration plant; the ash (also known as the reaction ash or the reaction product) is mixed in combination, and the appropriate amount of the semiconductor chemical mechanical polishing process is added. The sludge powder is uniformly mixed and then melt-treated to form a glass-melt-Si-O-mesh structure, which can envelop the heavy metals remaining in the slag lattice, so that heavy metals are not easily dissolved. Replace part of the cement' with sand, water, etc. into a cement mortar, in the amount of substitution 5~30 ° /. The range of curing strength can be higher than that of pure cement mortar, and its fluidity value (construction softness) is better than that of pure cement mortar, and the setting time is similar. It is found from the test results of compressive strength that the refining slag can greatly improve the strength of the early (1~7 days). Therefore, the early strength of the refining sand test body is mostly higher than that of the pure cement mortar, and the rest of the samples are tested. It is similar, and the 14~90 day age is higher than the strength of pure cement mortar, exceeding about 7~21%. The effect is very good. Moreover, the slag powder has been subjected to toxicity analysis and dissolution test results. The amount of heavy metal dissolved is much lower than the regulatory value stipulated by the Environmental Protection Agency 29 201245103. The test results show that the slag can be used in place of 5 to 30% of cement and can be used as an environmentally friendly cement. Accordingly, the present invention can recycle and utilize the fly ash and washing ash of the waste incineration plant, thereby reducing the demand for fly ash, washing ash and chemical mechanical grinding sludge landfill, and also preventing the above-mentioned harmful business waste. Environmental pollution caused by improper disposal, and the two kinds of waste can be converted into cement use without doubt of secondary pollution. It can reduce the environmental pollution and damage caused by cement manufacturing; the reason is that the invention does meet the requirements of the invention patent and submits an application according to law.
