以石英磚研磨污泥與水庫淤泥製備輕質骨材之方 法 The method of preparing lightweight aggregates with quartz brick grinding sludge and reservoir sludge law

本發明係與石英磚研磨污泥及水庫底泥之廢棄物回收再利用技術領域有關,更詳而言之是一種利用石英磚研磨污泥及水庫底泥之特性,製成輕質骨材之再利用技術,俾利輕質骨材之產製及應用者。 The invention relates to the technical field of waste brick recycling and utilization of quartz brick grinding sludge and reservoir sediment, and more specifically, the utility model utilizes the characteristics of quartz brick grinding sludge and reservoir sediment to make lightweight aggregate material. Reuse technology, the production and application of lightweight lightweight aggregates.

瓷磚廠之石英磚研磨程序會產生大量之污泥,該污泥進入廢水處理廠,經混凝、沉澱及污泥脫水等處理程序成為廢污泥餅後,多作為窪地填土或掩埋場之覆土,實為資源之浪費。探究石英磚研磨污泥難再利用之主因係夾雜磚坏粉屑及研磨片掉落之顆粒與成分、廢水處理及污泥脫水添加之混凝劑/助凝劑/調理劑等。 The quartz brick grinding process of the tile factory will produce a large amount of sludge. The sludge enters the wastewater treatment plant and is used as a waste sludge cake after being treated as a waste sludge cake by coagulation, sedimentation and sludge dewatering. Covering the soil is a waste of resources. The main reason for the difficulty in reusing quartz brick grinding sludge is the coagulation agent/coagulant/conditioner added to the dirty powder and the particles and components of the abrasive disc, the wastewater treatment and sludge dewatering.

此外,在水庫淤泥方面,由於水庫淤泥直接影響水庫有效蓄水量,故主管機關多視淤泥累積狀況進行必要之浚渫。浚渫挖除之淤泥多屬天然黏土、細砂,並含有機質,故可作為製成紅磚、土地改良、花卉栽培等用途,近年亦有將浚渫淤泥製成輕質骨材者。 In addition, in the case of reservoir silt, since the reservoir silt directly affects the effective water storage capacity of the reservoir, the competent authority will take the necessary accumulation of sludge accumulation status. The mud excavated by cockroaches is mostly natural clay, fine sand, and contains organic matter, so it can be used for making red bricks, land improvement, flower cultivation, etc. In recent years, there are also those who make slag sludge into lightweight aggregates.

習知有關石英磚研磨污泥或/及水庫淤泥製成輕質骨材之相關技術甚多,如中華民國發明第289016號「輕質骨材之製造方法」(由飛灰、氧化鎂固化劑、改性劑、調合劑、安定劑等混合燒成)、第280343 號「輕質建築物骨材」(為建築用之中空骨架及內置輕質填充材料)、第177808號「冷結型飛灰輕質骨材之製造方法」(由飛灰、底灰、水淬爐石、河砂加上結合料、黏結劑蒸氣冷結而成)、公開編號第200934594號「下水污泥與瓷磚磨光灰混合燒結體及其輕質骨材製法」(將下水污泥與瓷磚磨光灰混合燒結)、公開編號第200930678號「輕質骨材的製造方法」(以水庫淤泥及固態廢棄物混合造粒,裹上熔融層燒結而成)、公開編號第200909376號「垃圾焚化飛灰資源再製輕質骨材方法」(飛灰加矽鋁酸鹽造粒後以旋轉窯燒成)、公開編號第200909377號「高性能淤泥輕質骨材製作方法」(以水庫淤泥加含碳化矽添加劑,造粒後以旋轉窯燒成)等專利案。 There are many related technologies related to quartz brick grinding sludge or / and reservoir sludge made of lightweight aggregates, such as the Republic of China Invention No. 289016 "Manufacturing Method of Lightweight Aggregate" (by fly ash, magnesium oxide curing agent) , modifier, blender, stabilizer, etc.), 280343 No. "Lightweight Building Bone" (for hollow skeletons for construction and built-in lightweight filling materials), No. 177808 "Manufacturing method for cold-bonded fly ash lightweight aggregates" (by fly ash, bottom ash, water) Quenching stone, river sand plus binder, binder vapor cold junction), No. 200934594 "Sewage sludge and tile polishing ash mixed sintered body and its lightweight aggregate method" (will be sewage sludge Mixed with ceramic tile ash ash, No. 200930678 "Manufacturing method of lightweight aggregates" (mixed with reservoir sludge and solid waste, sintered with molten layer), No. 200909376 Method for remanufacturing lightweight aggregates from waste incineration fly ash resources" (flying ash and strontium aluminate granulated and then fired in rotary kiln), No. 200909377 "Method for producing high-performance silt lightweight aggregate" (with reservoir sludge) Patent case including addition of niobium carbide additive, granulation and firing in a rotary kiln).

由廢棄之石英磚研磨污泥及水庫淤泥回收再製成有價值之輕質骨材,不僅可減少原物料之開採、保護地球環境,並可達到零廢棄、資源再利用之目的,實具一舉多得之效益,不過,目前為止尚無以石英磚研磨污泥及水庫淤泥共同製成輕質骨材之相關專利。 Recycling of waste quartz brick grinding sludge and reservoir sludge to produce valuable lightweight aggregates not only reduces the exploitation of raw materials, protects the global environment, but also achieves the goal of zero waste and resource reuse. The benefits are more than enough. However, there are no patents related to the production of lightweight aggregates by quartz brick grinding sludge and reservoir sludge.
