项目摘要

The aim of this study is to make it clear how to treat high strength of organic wastes and wastewater effectively using 'Thermophilic Oxic Process' (TOP), There are close similarities between TOP and conventional composting method. the former is, however, to make high strength of organic wastes and wastewater change into inorganic compounds like CO_2 and H_2O in a very short term, the latter is to produce composts.The experiments were performed using both bench- and pilot-scale plants to investigate the most suitable way of treating wastes like piggery ones and wastewater, harvested and dehydrated blue-green algae and sewerage sludges, and to set the parameters like BOD loading, aeration strength and materials for controlling water content.Results obtained in a series of experiments were summarized as shown below ; (1) It was important to equalize consumption quantities of organic wastes and water evaporation in view of effective treatment of organic wastes. (2) It was possible to calc … More ulate heat consumption necessary for perfectly treating organic wastes from the balance of heat in a system. (3) Addition of used cooking-oil and mixing were very effective in case of the shortage of heat sources. (4) Addition of wastes and wastewater once a day was appropriate, and mixing was important for penetrating them into materials equally (5) As a material for controlling water content, reeds and porous plastic tips were available. (6) Aeration strength slightly depended on the condition of wastes and wastewater. It was set at 100 L・min^<-1>・m^<-3>. (7) Rapid and active growth of thermophilic bacteria and biodegradation caused marked rise of temperatur into around 60-70ﾟC in this fermentation systems, and it was observed that perfect treatments of wastes and wastewater were possible on the condition of filling the above-mentioned requirements. (8) Bacillus sp.with menaquinone-7, which cells contained CTAB,mainly contributed to the biodegradation of extra sludges.Thermophilic oxic processes which have been developed in this study is now used in some food processing factories.

本研究的目的是阐明如何利用高温好氧工艺（TOP）有效地处理高浓度有机废弃物和废水。本试验采用小型和中试规模的试验装置，研究了猪场废弃物、生活污水、蓝藻收获和脱水、污水污泥等的最佳处理方法，通过一系列的试验，得出如下结论：（1）有机废弃物的消耗量与水分蒸发量的平衡是有效处理有机废弃物的重要条件。(2)可以计算出 ...更多信息从系统的热量平衡中计算出有机废物完美处理所需的热量消耗。(3)在热源不足的情况下，添加废食用油和搅拌是非常有效的。(4)每天添加一次废物和废水是合适的，混合是重要的，以使它们均匀地渗透到材料中。（5）作为控制含水量的材料，可以使用芦苇和多孔塑料尖端。(6)曝气强度与垃圾和废水的状况有一定的关系。设定为100 L·min^<-1>·m^<-3>。(7)高温菌的快速活跃生长和生物降解使发酵系统的温度显著升高，达到60-70 ℃左右，在满足上述要求的条件下，可以实现对废物和废水的理想处理。(8)该菌主要对剩余污泥的生物降解起作用，其菌体中含有CTAB，并含有甲基萘醌-7。少
