Treatments of domestic wasted water by bamboo charcoal and their recycling systems

（1）在水溶液中测定了竹炭对表面活性剂的吸附等温线。所用竹炭为不同路线温度下制备的不同细化程度的竹炭。竹炭对两种表面活性剂的吸附亲和力随竹炭细化程度的降低而增加。结果表明，竹炭的微孔在吸附过程中起着重要作用。讨论了吸附亲和力与竹炭化学性质的关系，以确定竹炭对表面活性剂的优先吸附行为。(2)在水溶液中测定了吸附剂对苯酚和双酚A的吸附等温线。所用吸附剂为竹炭、活性炭和环糊精聚合物珠。分子模拟研究也进行了Monte Carlo模拟的分子力学（MM），以确定优选的络合物形成的苯酚和双酚A的环糊精。(3)以竹炭、南瓜、松果等天然木本煤为原料，研究了它们对环境缓蚀剂的截留率。比表面积与竹炭相当的吸附质对松果都有较强的吸附作用。吸附剂的分子大小对吸附有影响。(4)环糊精包合物对竹炭吸附性能的研究。结果表明，在毛笋中包覆环糊精后，得到部分被排除的趋势，且排除率上升，而在长节竹炭中则有所减少。结果表明，改性竹炭的分子大小影响其吸附性能。

(1)The adsorption isotherms of surfactants onto bamboo charcoals were measured in aqueous solution. The bamboo charcoals used were different types of refinement degree prepared from different route temperature. In general, the adsorption affinities for the both surfactants increased with decreases in the refinement degree of bamboo charcoals. The results indicated that fine pores over size of bamboo charcoals played an important role of the adsorption. The relationship between adsorption affinities and chemical properties were also discussed in order to determine preferred adsorption behaviors of surfactants onto bamboo charcoals.(2) The adsorption isotherms of phenol and bisphenol A onto adosorbents were measured in aqueous solution. The adsorbents used were bamboo charcoal, activated carbon, and cyclodextrin polymer beads. Molecular modeling studies were also performed by means of Monte Carlo simulation on molecular mechanics (MM)to determine the preferred complex formation of phenol and bisphenol A by cyclodextrins.(3) The rejection of environmental inhibitor was measured by using the natural woody coals such as the bamboo charcoal, pumpkins, and pinecones in aqueous solution. Any adsorbate had comparatively adsorbed the pinecone that the specific surface area was as large as bamboo charcoal. The molecular size of adsorbents influenced the adsorption.(4) The study of the adsorption ability by using the complex that coated the cyclodextrin to the bamboo charcoals. The result in which obtaining the tendency that part was excluded by coating the cyclodextrin in the mousou bamboo and the rejection rises, and providing and decreasing in long-jointed bamboo charcoal. The results suggested that the molecular size influenced the adsorptivity of the reforming bamboo charcoal.
