与现有技术相比，本发明具有如下有益技术效果：
(1)本发明的微孔滤管具有脱硫、脱硝、催化降解有机有害物功能，性能优异，内部晶体结构组成是微小发泡体，晶粒间的半熔融状态相互紧密的牢固结合，致使微孔滤管的强度经检测高于碳化硅氧化铝滤管，抗压强度达17mpa，而碳化硅氧化铝微孔滤管仅为12-13mpa。
本发明的微孔滤管其晶体结构为均匀镶嵌分布钛离子、钇离子和钨离子，钛离子是对有机有害物有催化降解功能的，而钇离子对硫、硝污染物有催化分解功能，钨离子是促进辅助钇离子对硝污染物催化分解作用的，所以本发明的微孔滤管是具有对二氧化硫、硝污染物及有机有害物催化降解功能的。经检测，本发明微孔滤管的脱硫效率达86％，脱硝效率79.4％，对有机有害的催化降解效率为84.82％。
经在电子显微镜下观察本发明的微孔滤管的微观贯穿数孔通道曲折细微，分布均匀，面积比例大，且内孔壁光滑，使得被过滤后的气、液阻力小，在使用运行中不易造成空隙堵死，阻力增大问题。同时，因孔径细小，分布面积大而均匀，使其过滤精度较大，幅度提高。经检测，本发明微孔滤管的过滤精度最高可达0.1微米-0.5微米，在空气净化领域过滤效率可达99.99％，达到高效过滤器级别，且过滤精度可据应用领域的不同，通过调控原料颗粒的大小实现，而普通碳化硅氧化铝微孔滤管的过滤精度一般在15-50微米。
(2)本发明的微孔滤管生产成本大幅度下降，原料采用非常廉价的石英矿等矿石原料及废弃的玻纤蓬松毡边角料球磨成各种粉料，成本仅是碳化硅氧化铝微孔滤管的1/12，是碳化硅微孔滤管的1/4，是玻璃体微孔滤管的1/2，原料成本大幅度降低。特别是解决了玻纤蓬松毡行业的大量废弃边角料固废环境污染的严重问题，解决了玻纤蓬松毡边角料固废不降解、严重污染环境的环保问题，变废为宝，实现核行业的环保可持续性发展。
采用大颗粒的粉体作为主造孔剂，用粘玉米面及羟丙甲基纤维素即作为生胚成型粘结剂，又作为辅助造孔剂，使得本发明微孔滤管的显孔隙率经检测达到44.9％，而碳化硅，氧化铝微孔铝管的显孔隙率仅为36％-39％。本发明的微孔滤管显孔隙率大幅度提高，使该微孔滤管在实际应用时初阻力和运行阻力有较大幅度降低，为用户节约可管的过滤运行成本。
(3)本发明的微孔滤管环保低耗。可有效的解决工业燃煤，火力发电等行业的高温除尘和同时进行脱硝脱硫问题，保证了排放达标可持续发展，也有效的解决了污水处理行业有机有害物催化降解现实问题。本发明的微孔滤管，烧结温度仅为820℃，烧结能耗是碳化硅氧化铝微孔滤管的1/3，是玻璃体滤管的2/3，能耗成本也有很大幅度的降低。
(4)本发明的微孔滤管，经强化高速模拟实验对比，其使用寿命较碳化硅氧化铝的微孔滤管延长近1倍，较玻璃体过滤管延长也接近1倍。此外，实际生产过程中，本发明一方面耗电成本和原料成本大幅度下降，另一方面微孔滤管物理性能及过滤性能与碳化硅氧化铝微孔滤管持平和超过，可以代替能耗高、运行成本高的碳化硅氧化铝微孔滤管。随着应用市场和领域的不断扩大，每年本发明的微孔滤管的大量应用，可为社会节约相当可观的电能，可使生存环境有效的大幅度减少有害物排放量，造福人类，并为使用单位节约可观的过滤达标的实际运行成本和采购成本。

(8)修整：将烧结成型的微孔滤管的两端分别用无齿锯齐边去除20mm，保证微孔滤管的有效长度为100mm，用压缩空气吹除微孔滤管内外壁上的浮灰，得到微孔滤管成品。
