摘　　要：为探究进水流量、矿化度、滤网孔径对微灌用微压过滤冲洗池水头损失的影响,开展微压过滤冲洗池运行特性的物理模型试验,建立了微压过滤冲洗池在微咸水条件下的水头损失预测模型。结果表明,在方差分析中仅流量对微压过滤冲洗池的水头损失影响显著,确定的影响因素排序由大到小为进水流量、矿化度、滤网孔径;该模型的决定系数R^(2)为0.955,均方根误差为0.0523,平均相对误差为3.20%。建立的模型可准确预测微咸水条件下的水头损失,研究成果可为泵前过滤设备的实际应用提供技术支撑。The effects of inlet flow,salinity and filter aperture on the head loss of micro-pressure filtration and clean-ing tank for micro-irrigation were investigated.The physical model test of the influence of the operating characteristics of the micro-pressure filtration and cleaning tank was carried out,and the head loss prediction model under the condition of brackish water in the micro-pressure filtration and cleaning tank was established.The results show that in variance analy-sis,only the flow rate has a significant impact on the head loss of the micro-pressure filtration and cleaning tank.The or-der of the influencing factors was sorted as follows:inlet flow,salinity,filter aperture.The determination coefficient R^(2) was 0.955,the root mean square error was 0.0523,and the average relative error was 3.20%.The established model can accurately predict the head loss under brackish water conditions.The research results can provide technical support for the practical application of pre-pump filtration equipment.
