上天梯地区发育的玻屑凝灰岩型沸石属斜发沸石。沸石 (质量 )∶盐酸 (体积 )为 1∶ 3的比例将 80目该沸石粉在 2 mol/L盐酸中浸泡 48h,加入适量反应助剂 ,经微沸回流 3h后过滤 ,将滤出液加热、蒸发、浓缩 ,当滤出液呈深黄色 ,密度为 1.2 1g/ m L时即制成沸石浸渍液净化剂 ,其体积分数为 1∶ 30 0 ,该净化剂可使草浆型造纸终端废水的 COD浓度降至国家 2～ 3级行业排放标准 (GB35 44-92 )。将滤出固体物洗涤、烘干 ,在温度 40 0～ 6 0 0°C下活化 3h后即制备成缺铝型沸石。此时 ,Al2 O3浸出率达 31%,硅铝比由 9.14提高到 15 .75 ,晶格破坏温度上升至 10 0 0°C以上 ,吸附性能也有所提高。该项研究同时制备固、液两种产品 ,而且无废弃物排放 ,实现了沸石资源的综合利用和零排放工艺 ,有一定的经济和环保意义。
The vitrinite tuffite developed on the Shangtianti area is clinoptilolite. Zeolite (mass): hydrochloric acid (volume) ratio of 1: 3 80 mesh of the zeolite powder immersed in 2 mol / L hydrochloric acid 48h, adding an appropriate amount of aids, after a micro-boiling reflux 3h filtration and the filtrate heated , Evaporated, concentrated, when the filtrate was dark yellow, the density of 1.2 1g / m L zeolite impregnated when the purification agent is made, the volume fraction of 1: 30 0, the scavenger can make straw pulp papermaking wastewater COD concentration dropped to 2 ~ 3 national industry discharge standards (GB35 44-92). The solid material was filtered off and washed, dried, and activated at a temperature of 40 0 ~ 600 ° C for 3h to prepare an aluminum-deficient zeolite. At this point, the Al 2 O 3 leaching rate reached 31%, the Si / Al ratio increased from 9.14 to 15.75, and the lattice destruction temperature increased above 10 0 ° C, and the adsorption performance also improved. The study also prepared solid and liquid products, and no waste emissions, to achieve the comprehensive utilization of zeolite resources and zero-emission process, a certain economic and environmental significance.
