Study on the Structural Element and Classification of the Water use and Waste Treatment System for Livestock Farming

这项研究涵盖了1989至1990年间的两年时间。1989年，向青森县各市发放了关于畜牧业用水和废水实际情况的问卷。主要结论如下：(1)大多数城镇的畜牧业用水来源为公共生活水源或私人水井。(2)在取值最高的城镇，农业需水量与生活需水量之比(计算)为43.9%。这些似乎表明，畜牧业的用水习惯是在没有脱离生活用水的情况下做的。接下来是对设施进行监管以降低公共供水系统成本的讨论。在下一阶段的研究中，水分需求模式及其与养殖管理的关系(指一种食物、取食时间、取食间隔等)。用2-…进行了实验研究牛棚里有更多的奶牛。分析结果，调整器的容量是基于需求模式的，而需求模式似乎受到养殖管理方法的影响。1990年，本研究在以下两个目标下进行了研究。(A)根据公共供水工程的建设情况，研究水资源转移(或不转移)的情况，并对用户的水资源转移动机进行分类。(B)观察和评估一些奶牛场的实际储存设施和废物量，这些奶牛场一直通过稀释的方式将废物重新用作肥料。通过案例研究(上述(A)项)反映了上述问卷的结论，认为问题似乎发生在畜牧业用水计划与生活用水分开的时候。根据评价(B)，似乎除了库存外，还应从再利用和处理的角度审查废物储存设施的规划方法。较少

This study covered a 2-yr period between 1989 and 1990. The questionnaire on the actual condition of the water use and waste in livestock farming was distributed to every municipalities in Aomori prefecture in 1989. The conclusions of analyzing the answer are as follows.(1) The water for livestock farming was obtained from public domestic water resources or private well in the most cities and towns. (2) The ratio of the water demand (calculated) for the farming to domestic one (calculated) was 43.9% in the town getting highest value. These seem to indicate that the livestock farming water use used to do in the condition unseparated from domestic water use. This is followed by a next discussion of regulating facilities to make a public water supply system's cost lower. In the next stage study, the water demand pattern and the relation between that pattern and breeding management (would mean a kind of food, feeding times, feeding interval and etc.) were studied experimentally by using 2- … More cows in the shed. Analyzing the results, the volume of the regulator is based on the demand pattern, which was appeared to be infulenced by the method of the breeding management.In 1990, the study had done under the two objectives as follows. (a) To research the cases that the water resources were transferred (or not) according to construction of a public water supply project and to classify the user's motivation of water resource transfer. (b) To observe and evaluate the actual stock facilities and waste volume from some dairy farms which have been reusing the waste as the fertilizer by means of diluting. Through the case study (above-mentioned(a)) reflected the conclusions of above the questionnaire, it was considered that the problem seems to occur when the livestock farming water use was planed to be separated from domestic water use. By the evaluation (b) it was appeared that the planning method of the waste stock facilities should be examined from the view of re-using and treatment in addition to stock. Less
