Pilot Experiment Research On The "Turbid Water Hydraulic Power"

Turbid water hydraulic separator device (hereinafter referred to as "device") is a new type of water purification devices developed by the Department of Hydraulics Research Group members of the Institute of Hydraulic and Civil Engineering of Xinjiang Agricultural University.The "device" in the room has been preliminarily achieved. In order to make it be applied to water plant, agricultural water-saving irrigation and other projects' sediment treatment.In this paper, through the pilot experiment convert the research results of the interior and also provide a reliable basis popularization and application for the "device".Firstly,pilot testing has done a detailed test on the relationship of different factors influence the separation between the water and sediment.There have an analysis on the "device" separation performance of water and sediment according to test results.Secondly, we carried out the clearing rate test in the pilot "devices".Then the test results and laboratory tests in the clearing rate were analysed comparatively.Finally, the formula of outflow capacity of water of the "device" were analysed under the standard of the overflow turbidity 1000NTU.The discipline of overflow performance test on a series model indoor was verified through experiment research and analysis; Under a certain circumstances of the diameter of bottom outlet and the standard of overflow,with the increase of the outflow concentration, the clearing rate of "device" decreased;with the increase of the diameter of column, the clearing rate of the"device" increased; Through the research on the pilot experiment, the phenomenons were found as follows:The "device" can obtain the maximum capacity of water outflow under the limited condition of a stable outflow capacity and clogging of the bottom hole was not occurred; Adjusting the appropriate inflow capacity to get into the relatively clear water.Finally, the relation between the overflow capacity of the "device" and the diameter of cylinder was obtained by numerical fitting.
