A consecutive process involving chemical coagulation,electro-static adsorption and adsorption,applied to purifing fibreboard waste-water was found very effective in laboratory conditions.The CODcr of the waste water droped from 1988ppm to 35ppm,the efficiency which is 98%.The quality of purified water revealed itself to be colorless,tasteless and transparent.In this process,the used activated carbon can be regenerated with no need of regeneration furnace.

Diacetylchitin(DAC) was used for coating adsorption resin to produce a blood compatible adsorbent. The methods of coating adsorption resin with DAC were investigated, and the DAC-coated resin obtained was studied for their blood compatibility and adsorption capacities for toxic substances. Based on these studies, the DAC is believed to be full of promise as a blood compatible material for coating resin used as a hepatic support.

The delignifieation mechanism of NaOH—Na_2SO_3-AQ pulping(Na_2SO_3and AQ only as additives)for wheat straw pulping,has been studied. Investigations on its delignification phases show that high yield pulps with sup- erior quality can be obtained.Carbohydrate dissolution in cooking is noticed,and adsorption of xylose on fibers at the later periods of the cook have also been obse- rved. Delignification topochemistry is studied by SEM—EDXA technique.Nothing specific has been noted on the topochemistry of secondary wall(S),compound middle lammela(CML)and cell corner middle lammela(CC)of the fiberous cells during the early cooking stages until the temperature comes to 140℃.Then,the di- lignification rates in CC and CML appears to be more rapid than in S.Such a pre- dominance in CML and CC dilignification tends to shift the deliberation point to around 140-145℃,giving a higher lignin content pulp with Kappa number 18. The three ingredients composing the cooking liquor of NaOH-Na_2SO_3-AQ pu- lping are seemingly complementary to one other.Enhancement in delignification rate and blocking of carbohydrate degredation are thus effected. The dissolved lignins are being seperated and studied by UV,IR and ~1HNMR. It is observed that most of the ester linkages in lignins are being attacked in the early cooking time.Either early or mid-way in the cooking,the syringly units in lignin are always dissolved better than the guaiacyl units.Keeping the cook at a high temperature for a long duration will bring about lignin condensation.

本文着重研究了麦草 NaOH-Na_2SO_3-AQ 法蒸煮中木素脱除的局部化学和结构变化。蒸煮脱木素阶段性和纤维分离点的研究,证明了该法蒸煮成浆得率高、强度好的可能性。并观察了碳水化合物在蒸煮过程中的溶出情况和木糖在蒸煮后期在纤维上的吸附。局部化学研究表明:蒸煮初期,麦草纤维细胞的各主要微区不存在显著的脱木素局部化学效应;140℃以后,CC 区和 CML 区的脱木素速度明显比 S 区快,胞间层木素的优先溶出使纤维分离点提前,得率提高。浆料、黑液及其溶出木素分析显示了蒸煮液中三种有效成份在脱木素过程中的互补作用。对不同蒸煮阶段的黑液木素进行波谱分析,证明麦草木素中以酯键联接部分在升温初期即大量溶出。无论是碱易溶木素还是“碱不易溶木素”,脱除时优先溶出的总是紫丁香基型木素。高温下长时间保温将可能引起木素缩合。
