Description
技术领域technical field
本发明涉及一种颗粒填料的生产方法，尤其涉及一种利用工业废物高炉水渣为主要原料制备新型曝气生物滤池颗粒填料方法。The invention relates to a production method of granular packing, in particular to a method for preparing a new type of granular packing for aerated biological filter by using industrial waste blast furnace slag as the main raw material.
背景技术Background technique
本发明所涉及的技术主要包括高炉水渣应用、陶粒填料制备等技术。现有技术介绍如下：The technology involved in the invention mainly includes technologies such as blast furnace slag application and ceramsite filler preparation. The prior art is introduced as follows:
1.高炉水渣1. Blast furnace slag
高炉水渣是炼铁过程中产生的，当它浮在铁水层上面并以高温熔融状态流出时，水淬急冷而成的一种粒化废渣，俗称“水渣”。现阶段对高炉水渣的应用主要集中在以下几个方面：Blast furnace slag is produced during the ironmaking process. When it floats on the molten iron layer and flows out in a high-temperature molten state, it is a kind of granulated waste slag formed by water quenching and quenching, commonly known as "water slag". At present, the application of blast furnace slag mainly focuses on the following aspects:
(1)生产建材(1) Production of building materials
1)生产水泥1) Production of cement
高炉水渣经水淬急冷，来不及形成矿物结晶而把其中的化学能储存于形成的玻璃体中，具有较高的潜在活性，当磨细以后，在水泥熟料矿物的水化产物、石灰、石膏等激发剂作用下，它与水作用可生成水化硅酸盐等水化产物。After the blast furnace slag is quenched and quenched by water, the chemical energy in it is stored in the formed glass body before it can form mineral crystals, which has high potential activity. Under the action of other activators, it reacts with water to generate hydration products such as hydrated silicate.
2)水渣微粉用于混凝土2) Water slag powder is used in concrete
矿渣微粉是将高炉水渣磨细至一定细度的粉体材料，用于水泥的混合材料和混凝土的掺合料。高炉水渣微粉作为混凝土的掺合料，不仅能取代等量的水泥，具有良好的经济效益，而且能显著提高混凝土的技术性能，是国际公认的生产高性能混凝土的主要组分之一。Slag micropowder is a powder material that grinds blast furnace slag to a certain fineness, and is used as a mixture of cement and admixture of concrete. As a concrete admixture, blast furnace slag powder can not only replace the same amount of cement, which has good economic benefits, but also can significantly improve the technical performance of concrete. It is internationally recognized as one of the main components for the production of high-performance concrete.
由于矿渣微粉作为混凝土的掺合料有良好的技术效益和经济效益，近年来，我国一些大城市的建筑工程应用矿渣微粉混凝土已经逐步展开，发展前景良好。Because slag micropowder has good technical and economic benefits as a concrete admixture, in recent years, the application of slag micropowder concrete in construction projects in some large cities in my country has gradually started, and the development prospect is good.
(2)生产硅肥(2) Production of silicon fertilizer
硅肥是一种以含氧化硅(SiO2)和氧化钙(CaO)为主的矿物质肥料，它是水稻等农作物生长不可缺少的营养元素之一。硅肥现被国际土壤学界确认为继氮(N)、磷(P)、钾(K)之后第四大元素肥料。生产硅肥的主要原材料为高炉水渣。Silicon fertilizer is a mineral fertilizer mainly containing silicon oxide (SiO 2 ) and calcium oxide (CaO). It is one of the indispensable nutrients for the growth of rice and other crops. Silicon fertilizer is now recognized by the international soil science community as the fourth largest element fertilizer after nitrogen (N), phosphorus (P) and potassium (K). The main raw material for producing silicon fertilizer is blast furnace slag.
硅肥的加工过程为：把水渣磨细，细度为80目～100目，添入适量硅元素活化剂，搅拌混合后装袋(或搅拌混合造粒后装袋)，硅肥的工业化生产比较简单。The processing process of silicon fertilizer is as follows: grind water slag finely, with a fineness of 80 mesh to 100 mesh, add an appropriate amount of silicon element activator, stir and mix and then bag (or stir and mix and granulate and then bag), the industrialization of silicon fertilizer Production is relatively simple.
(3)生产微晶玻璃(3) Production of glass-ceramic
微晶玻璃是近几十年发展起来的一种用途很广的新型无机材料。高炉水渣微晶玻璃产品，比高碳钢硬，比铝轻，其机械性能比普通玻璃好，耐磨性不亚于铸石，热稳定性好，电绝缘性能与高频瓷接近，矿渣微晶玻璃用于冶金、化工、煤炭、机械等工业部门的各种容器设备的防腐层和金属表面的耐磨层以及制造管材等，使用效果很好。Glass-ceramics is a new type of inorganic material that has been developed in recent decades and has a wide range of uses. Blast furnace slag glass-ceramic products are harder than high-carbon steel and lighter than aluminum. Glass-ceramic is used in metallurgy, chemical industry, coal, machinery and other industrial sectors for anti-corrosion coatings of various container equipment and wear-resistant coatings on metal surfaces, as well as in the manufacture of pipes, etc., with good results.
2.陶粒填料2. Ceramsite filler
陶粒填料是采用优质粘土为原料，经团粒、高温烧制、筛分等一系列工艺加工而成的水处理填料。普通的陶粒填料的原料主要是粘土、页岩等，需要进行采挖，并且在制作时通常需要进行烧结，需要耗费很多的煤炭资源，这在当今能源紧缺的情况下势必造成其制作成本的增加。Ceramsite filler is a water treatment filler that uses high-quality clay as raw material and is processed by a series of processes such as agglomeration, high-temperature firing, and screening. Ordinary ceramsite fillers are mainly made of clay, shale, etc., which need to be excavated, and usually need to be sintered during production, which consumes a lot of coal resources, which will inevitably lead to its production cost under the current energy shortage situation. Increase.
高炉水渣颗粒填料同普通的陶粒填料的生产过程的区别主要在于原料的不同。普通陶粒填料的原料主要是粘土、页岩等，而高炉水渣颗粒填料的主要原料高炉水渣为工业废物，相对于粘土和页岩来说，高炉水渣的原料成本较低，因此，高炉水渣颗粒填料相对于普通陶粒填料在成本方面有很大优势。The difference between the production process of blast furnace slag particle filler and ordinary ceramsite filler mainly lies in the difference of raw materials. The raw materials of ordinary ceramsite filler are mainly clay, shale, etc., while the main raw material of blast furnace slag granular filler is industrial waste. Compared with clay and shale, the raw material cost of blast furnace slag is lower. Therefore, Compared with ordinary ceramsite filler, blast furnace slag particle filler has great advantages in cost.
关于高炉水渣颗粒填料的制作特别是使用粘结剂将高炉水渣进行粘结的应用和研究，经检索，还未见相关报道。There is no relevant report about the production of blast furnace slag particle filler, especially the application and research of using binder to bond blast furnace slag.

(2)配料：称取步骤(1)制得高炉水渣700g，加入其质量百分比为8％的水泥和其质量百分比为4％的801胶，充分混合，搅拌均匀。(2) Batching: Weigh 700 g of the blast furnace slag obtained in step (1), add 8% cement and 4% 801 glue by mass, mix thoroughly and evenly.
(3)成球：将步骤(2)制取的混合物加工成直径为3～6mm的球形颗粒。(3) Balling: process the mixture prepared in step (2) into spherical particles with a diameter of 3-6 mm.
(4)养护：将步骤(3)制取的球形颗粒每天撒水6次，养护3天后，即得高炉水渣颗粒填料成品，测得其密度为2.55g/m3，水冲刷损失率为1.6％。(4) Curing: Sprinkle the spherical particles prepared in step (3) with water 6 times a day, and after curing for 3 days, the finished product of blast furnace slag particle filler is obtained. The measured density is 2.55g/m 3 , and the water erosion loss rate is 1.6 %.
