Description

一种改性浮岩生物反应器装置A modified pumice bioreactor device

技术领域 technical field

本发明属水处理装置领域,尤其涉及一种改性浮岩生物反应器装置。 The invention belongs to the field of water treatment devices, in particular to a modified pumice bioreactor device.

背景技术 Background technique

改性浮岩具有较大的比表面积和较强的吸附性能,因此,本研究选用改性浮岩作为主要填料。 Modified pumice has a large specific surface area and strong adsorption performance, so this study chooses modified pumice as the main filler.

浮岩(pulnice),是火成岩(lava)材料中的一种喷出岩,主要由火山玻璃、矿物组成。火山爆发时,岩浆中产生出的大量火山气体形成泡沫,随后泡沫冷却,气体被“封存”在浮岩中。浮岩中的气泡约占岩石总体积的70%以上,气泡间只有极薄的火山玻璃和矿物,因而可以浮于水面之上。浮岩外形似炉渣,表面多孔成蜂窝状,颜色浅淡,多为白色、灰白色或者灰褐色。浮岩是我国资源量大且分布较广的一类非金属矿产,储量仅次于意大利、希腊,居世界第三位,产地涉及黑龙江、吉林、辽宁、内蒙、山西、新疆、云南、海南等省区,被广泛应用于工业、农业等诸多领域,在化学工业中用作过滤剂、干燥剂、催化剂、填充剂以及农用杀虫剂的载体和肥料的控释剂,也可直接用作建筑材料。 Pumice (pulnice) is an extrusive rock in igneous rock (lava) materials, mainly composed of volcanic glass and minerals. When a volcano erupts, a large amount of volcanic gas is produced in the magma to form a foam, and then the foam cools, and the gas is "sealed" in the pumice. The air bubbles in the pumice rock account for more than 70% of the total volume of the rock, and there are only very thin volcanic glass and minerals between the air bubbles, so they can float on the water. The shape of the pumice is like slag, the surface is porous into a honeycomb shape, and the color is light, mostly white, off-white or taupe. Pumice is a kind of non-metallic mineral with large resources and wide distribution in my country. Its reserves are second only to Italy and Greece, ranking third in the world. Its production areas involve Heilongjiang, Jilin, Liaoning, Inner Mongolia, Shanxi, Xinjiang, Yunnan, Hainan, etc. It is widely used in many fields such as industry and agriculture. In the chemical industry, it is used as a filter, desiccant, catalyst, filler, and a carrier of agricultural pesticides and a controlled release agent for fertilizers. It can also be used directly as a construction agent. Material.

近年来,国内外对浮岩的吸附性能及其应用开展了初步研究,发现浮岩具有独特的气孔结构和良好的吸附能力。 WhithanA.G.等通过浮岩浸水漂浮试验发现,不同密度、大小和产地浮岩的吸水速率虽有明显差异,但其内部气孔的相互连通性较好,因此具有很好的传质效果。Bahri Ersoy等研究了产自土耳其Tatvan地区的浮岩,发现其热稳定性高达900℃,因粒径大小不一,孔径分布在0.05um~2mm之间,其比表面积和总孔隙率随粒径的减小而增加。Maria Rosaria Panucci等研究发现,浮岩对水溶液中Cd2+的去除率与Cd2+的初始浓度成显著正相关。  Fethiye Gode等、Mustafa Yavuz等研究也表明,浮岩对水溶液中重金属Cu2+、Cr3+有较好去除率,并且在pH=8时可达80%。 Feryal Akbal研究发现,浮岩对水溶液中的亚甲基蓝和结晶紫有明显吸附作用,能有效去除水体色度。宋秀环等通过比较几种非金属矿物表面积和硫化氢吸附实验结果,发现物理吸附作用中,由强到弱的顺序为:硅藻土>麦饭石>斜发沸石>浮岩。化学吸附主要是矿物所含过渡金属含量对吸附能力起主导作用,对硫化氢的吸附能力依次为:浮岩>硅藻土>麦饭石>沸石。 In recent years, preliminary studies have been carried out on the adsorption performance and application of pumice at home and abroad, and it is found that pumice has a unique pore structure and good adsorption capacity. WhithanA.G. et al found through pumice immersion and floating tests that although the water absorption rates of pumice with different densities, sizes and origins are significantly different, their internal pores are well interconnected, so they have good mass transfer effects. Bahri Ersoy et al studied the pumice rock produced in the Tatvan region of Turkey, and found that its thermal stability is as high as 900 ° C. Due to the different particle sizes, the pore size distribution is between 0.05um and 2mm, and its specific surface area and total porosity vary with particle size. decrease and increase. Maria Rosaria Panucci et al found that the removal rate of pumice to Cd 2+ in aqueous solution is significantly positively correlated with the initial concentration of Cd 2+ . Studies by Fethiye Gode et al. and Mustafa Yavuz et al. also show that pumice has a good removal rate for heavy metals Cu 2+ and Cr 3+ in aqueous solution, and can reach 80% at pH=8. Feryal Akbal's research found that pumice has obvious adsorption effect on methylene blue and crystal violet in aqueous solution, and can effectively remove the chroma of water body. By comparing the surface area of several non-metallic minerals and the results of hydrogen sulfide adsorption experiments, Song Xiuhuan et al. found that the order of physical adsorption from strong to weak is: diatomite > medical stone > clinoptilolite > pumice. Chemical adsorption is mainly due to the transition metal content contained in minerals playing a leading role in the adsorption capacity, and the adsorption capacity for hydrogen sulfide is in the following order: pumice > diatomaceous earth > medical stone > zeolite.
