Description
技术领域
本发明涉及气体净化技术领域，尤其是涉及一种废气过滤装置的生物复合材料制备方法。
背景技术
废气污染大气环境是世界最普遍最严重的环境问题之一。各类生产企业排放的工业废气是大气污染物的重要来源。工业废气包括有机废气和无机废气。有机废气主要包括各种烃类、醇类、醛类、酸类、酮类和胺类等；无机废气主要包括硫氧化物、氮氧化物、碳氧化物、卤素及其化合物等。大量工业废气如果未经处理达标后排入大气，必然使大气环境质量下降，给人体健康带来严重危害，给国民经济造成巨大损失因此，废气需要进行净化后达标才可以排放。
常见的废气过滤吸附装置一般采用活性炭吸附材料，单一使用活性炭吸附，吸附效果不佳，可过滤的有害物质种类少，烟气中的水分、烟尘、焦油等物质堵塞活性炭孔隙。
发明内容
有鉴于此，本发明的目的是针对现有技术的不足，提供一种废气过滤装置的生物复合材料制备方法，可有效去除烟气中的臭味气体和有机废气，适用范围广泛，节约成本，减少二次污染。
为达到上述目的，本发明采用以下技术方案：一种废气过滤装置的生物复合材料制备方法，废气过滤装置的生物复合材料包括第一纱网，条块状生物质材料和第二纱网；条块状生物质材料设置于第一纱网和第二纱网之间；第一纱网和第二纱网为20-30目过滤网；条块状生物质材料表面喷洒微生物制剂制作成微生物菌床，微生物制剂中植物乳杆菌、沼泽红假单胞菌、产朊假丝酵母菌、枯草芽孢杆菌、地衣芽孢杆菌和长双歧杆菌菌液的体积比为2.5～3.5：1.5～2.5：3～4.5：1.2～2.5：1～1.5：0.8～1，植物乳杆菌、沼泽红假单胞菌、产朊假丝酵母菌、枯草芽孢杆菌、地衣芽孢杆菌和长双歧杆菌菌液的浓度分别(4～6.5)×108个/mL，(3～5)×108个/mL，(4～6)×108个/mL，(4～6)×108个/mL，(1.6～5)×108个/mL，(2～4)×108个/mL。
进一步地，相邻条块状生物质材料互相平行设置，条块状生物质材料的宽度为5-8mm，厚度为7-12mm。
进一步地，每1m3条块状生物质材料喷洒0.01-0.03m3微生物制剂。
进一步地，条块状生物质材料为木质纤维材料。
本发明的有益效果是：
本发明废气过滤装置的生物复合材料条块状生物质材料设置于第一纱网和第二纱网之间，条块状生物质材料表面喷洒微生物制剂制作成微生物菌床，可使微生物有效附着，同时条块状生物质材料为微生物提供一定的养分和繁殖环境，提高微生物繁殖速度。经过培养微生物制剂菌丝网络均匀分布于第一纱网和第二纱网之间，可有效去除烟气中的臭味气体和有机废气，去除率高达90％以上。
条块状生物质材料来源广泛方便，几乎无成本，在使用一段时间后生物质材料为微生物提供的生存环境下降，不适宜微生物繁殖时可进行更换，更换后的生物质材料可以投入低温热解炉进行处理，减少了二次污染物产生。
本发明废气过滤装置的生物复合材料可以与活性炭结合过滤废气，设置于活性炭过滤层前端，可延长后续活性炭使用寿命1倍以上，节约活性炭使用成本50％以上。
本发明废气过滤装置的生物复合材料可根据不同过滤需求调整条块状生物质材料的分布，条块状生物质材料可平行或者交叉设置，相邻条块状生物质材料的间距和倾斜角度也可自由调整，条块状生物质材料与纱网尺寸相配合，适用过滤装置的范围广泛，满足多种废气的过滤要求。
