Improvement of Water and Soil Conditions of Stream with Charcoal Made on Thinnings of Japanese Cedar

现在，木炭被用于许多领域，就像土壤和水的质量一样提高，因为它具有显著的吸引力。However，charcoal adsorption的影响和功能机制并没有得到不同的正确性，并且预先提供了charcoal的模糊图像。因此，本研究的目的是确定碳水化合物关系的不利性及其功能机制，通过实验室实验对下游环境的改善产生了糖，以产生日本雪松和多种阔叶树的想法，以及营销糖，用于纪念性使用和长凳（日本传统糖）。实验室实验的总体描述和结果都在后面。1）在每15升分散的水中投入500克的碳水化合物后，营养集中通量随着时间的推移而变化，通过离子色谱法进行了测量。它被指以木炭制成的含有日本雪松的思想的低浓度Cyli D1-Cyli D1和D1。 ... More KI-D1 than marketing charcoal for recreational uses and Bincho-tan， and the composition of charcoal made on thinnings of Japanese cedar remarkably pour。这些对销售木炭对非商业用途和Bincho-tall的影响将基于制造工艺的差异，如木炭生产的温度。既然这些替代的营养素应该与木炭的吸引力产生影响.（2）有人建议说，木炭的吸引力是用日本雪松制成的，就像它的宾丘坦一样强大。这将是因为木炭是用含日本雪松的想法制成的，具有明显的高毒性。3）用日本雪松的想法制成的50克木炭，以接近直径的0.5米放置在永久性的地方--装满1500 ppm悬浮颗粒的体积小于50微米，水中有1500 ppm的悬浮颗粒在冲绳岛取样，以确定木炭在日本雪松的精华上的吸收性。SS集中在7天内从1500 ppm减少到40 ppm的水中，并在可供悬挂颗粒使用的日本雪松上产生的显著吸引力。在日本雪松的思考上产生木炭的不利性上升到五个折叠的过程中，水被利用磁性苯乙烯分散，因为在接触时间中使用木炭产生的日本雪松的思考变成更长的时间。此过程eliminating suspended particles rapidly was named "disturbing filtration"。4）由disturbing filtration of charcoal made on thinnings of Japanese cedar by disturbing filtration is more than 5 times as fast as ordinary filtration which passes water containing suspended particles through charcoal layer simply。Less（低）

Nowadays, charcoal is used in many fields, such as soil and water quality improvement, because of its remarkable adsorbility. However, the effects and functional mechanism of adsorption of charcoal has not been varied correctly, prevailing vague image for charcoal. Thus, the purpose of this study is to identify the adsorbility and its functional mechanism of charcoal relations to stream environmental improvement by laboratory experiments with charcoals made on thinnings of Japanese ceder and several kind of broad-leaved trees, marketing charcoal for recreational uses and Bench-tan (Japanese traditional charcoal). Overall descriptions and results of laboratory experiments are follows.1) After entering 500g of each charcoal into 15l of distilled water, the nutrient-concentration fluctuations with time attributed to elution were measured with ion chromatography. It was indicated that charcoal made on thinnings of Japanese cedar contains considerably lower concentrations of ClィイD1-ィエD1 and … More KィイD1+ィエD1 than marketing charcoal for recreational uses and Bincho-tan, and the composition of charcoal made on thinnings of Japanese cedar remarkably pour. These impurities of marketing charcoal for recreational uses and Bincho-tall would be based on the differences of manufacturing process such as temperature of charcoal making. Since these eluted nutrients should interfere with adsorbility of charcoals.2) It was suggested that adsorbility of charcoal made on thinnings of Japanese cedar is as strong as that of Bincho-tan. It would be because that charcoal made on thinnings of Japanese cedar contains considerably high porosity.3) 50g of charcoal made on thinnings of Japanese cedar shattered into fragments with an average diameter of approximately 0.5m were placed in a stainless-basket and hunged in water containing 1500 ppm suspended particles with a diameter of smaller than 50μm which were sampled in Okinawa Island in order to estimate the absorbility of charcoal made on thinnings of Japanese cedar. SS concentration of the water were reduced from 1500 ppm to 40 ppm during 7 days and the remarkable adsorbility of charcoal made on thinnings of Japanese cedar available for suspended particles was shown. The adsorbility of charcoal made on thinnings of Japanese cedar rises up to five-fold by disturbing the water using magnetic stirrer because the contact time of particles with charcoal made on thinnings of Japanese cedar becomes longer. This process eliminating suspended particles rapidly was named "disturbing filtration".4) The adsorption rate of charcoal made on thinnings of Japanese cedar by disturbing filtration is more than 5 times as fast as ordinary filtration which passes water containing suspended particles through charcoal layer simply.
