The simple sewage disposal facilities with the use of organic materials for the purified the milking parlor cowshed waster water

1. 本项目旨在建立利用有机材料对牛棚奶房废水进行简单处理的方法。由于水处理设备结构简单，建造成本很低。材料与方法我们首先使用5个立方池（1m^3），与塑料管连接，即1^< 1 >池：第一个沉淀池，从储罐（20m^3）抽水，从2^<和>到4^< >池：带接触材料的曝气处理池，5^< >池：沉淀池。对水质进行了pH、BOD、SS、氮、正己烷等检测。结果与讨论1)设备的改进我们首次使用木炭和沸石作为微生物的接触材料，但它们是漂浮的，表面没有被微生物覆盖。由于这些原因，净化效果没有达到。所以我们把两罐接触材料从木炭和沸石换成了线状的布…更多的接触材料。为了调节储罐抽水废水的流量，我们在第一储罐前设置了流量调节装置。该设备将溢出的废水回流到储罐中，以保持恒定的流量。为了增加上一个沉淀池的清洗效果，我们安装了新的沉淀设备，该沉淀设备为V字坝，用于去除SS，并且我们拆除了流量调节设备和螺杆泵，改为设置气升泵，使废水流量更慢（3L/min）。由于这些变化，污水处理设施的净化能力得到了提高。2)废水和处理水分析：储存池原水和末沉淀池处理水的初始BOD和SS值（ppm）均较高，分别为650、170 （BOD）和330、72 （SS）。经过以上的改进，最后一个沉淀池排出的处理水得到了更低的值。但原水水质和污水处理设施能力的季节变化差异较大，因此接触材料和曝气设备的进一步改进显得十分重要。少

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.
