项目摘要

1. IntroductionThis projects were carried out for establish of the simple treatment with using organic materials of milking parlor waste water of cowshed. Because of the simple structure of the water treatment equipment, it was very cheap to build.2. Material and MethodsAt first we used five cubic tanks (1m^3), that were connected with plastic pipe, i.e., 1^<st> tank : the first precipitation tank which pumped up from store tank (20m^3), from 2^<nd> to 4^<th> tanks : aeration treatment tank with contact materials and 5^<th> tank : precipitation tank. We examined the water qualities, that were pH, BOD, SS, nitrogen and normal hexane etc..3. Result and Discussion1) Improvements of equipmentsFirst time we used charcoals and zeolites for contact materials of microbes, but they floated and the surfaces of them not covered with microbes. Because of these reasons purifying effects were not gained. So we changed two tanks of contact materials from charcoals and zeolites to string shape cloth c … More ontact materials. For to adjust the flow quantities of waste water, that pumped up from store tank, we settled the water flow adjust equipments in front of the first tank. This equipment retuned the overflowed waste water to the store tank for maintain the constant flow. To add more cleaning effects of last precipitation tank, we settled the new precipitation equipments, which had dam of V letter shape for to remove of SS. Moreover we removed the water flow adjust equipments and screw pump, and then set the air lift pump instead to make the more slow flow (3L/min.) of waste water. Because of these changes the purifying abilities of the sewage disposal facilities were improved.2) The analyze of waste water and treatment waterAt first BOD and SS values (ppm) of the original waste water at store tank and the treatment water from the last precipitation tank were rather high 650, 170 (BOD) and 330, 72 (SS) for each place. After these improvements above, we got the more low values for the treatment water which discharged from the last precipitation tank. But the variances of the qualities of original waste water and seasonal performances of abilities of sewage disposal facilities were sapposed to be huge, so that more improvements of contact materials and aeration equipments seemed to be great important.

1.前言本项目是为建立利用有机物料对牛舍挤奶厅废水进行简易处理而进行的。因为水处理设备结构简单，所以建造成本很低。材料和方法首先用塑料管连接5个1m^3的立方水槽，即1个水箱：第一个从储水池(20m^3)抽出的沉淀池，2个水箱到4个水箱：接触材料曝气处理水池和5个水箱：沉淀池。检测水质指标：pH、BOD、SS、氮和正己烷等。结果与讨论1)设备的改进第一次使用木炭和沸石作为微生物接触材料，但它们漂浮着，表面没有微生物覆盖。由于这些原因，提纯效果并不理想。因此，我们将两罐接触材料从木炭和沸石改为线形布料c…。更多真实的素材。为了调节从储水池中抽出的废水的流量，我们在第一个水箱前设置了水流量调节装置。该设备将溢出的废水回调到储水池中，以保持恒定的流量。为了增加原沉淀池的清洗效果，解决了新的沉淀池设备，设置了V字形挡墙，用于去除悬浮物。此外，我们还去掉了流量调节装置和螺杆泵，改为气升泵，使流量更慢(3L/min)。废水的排放。2)废水和处理水的分析储水池原水和末级沉淀池出水的BOD、SS值(Ppm)均较高，分别为650、170(BOD)和330(72)。经过上述改进后，最后一个沉淀池排放的处理水达到了较低的值。但原废水水质和污水处理设施处理能力的季节性变化很大，因此接触材料和曝气设备的进一步改进显得尤为重要。较少
