【摘要】 利用文献[1]所建立的沉淀池数值模型,分别计算平流式沉淀池在不同挡板位置、进水口流速和沉淀池长高比下的水流流场、悬浮物的浓度场和利用示踪剂计算的过流曲线。分析比较不同挡板位置、进水口流速、沉淀池长高比等对沉淀池运行效果的影响,并依此确定沉淀池合理的挡板位置、长高比及进水口流速。更多还原

【Abstract】 In this paper,the flow velocity fields,suspended solids concentration fields and flow-through curves in rectangular sedimentation tanks with different reaction baffles location,inlet horizontal velocity and length height ratio are simulated in detail using a developed mathematical model given in Reference 2.According to the numerical results,the influence of different reaction baffles location,inlet horizontal velocity and length height ratio on the operating efficiency is analyzed.Finally,the rational reaction baffles location,inlet horizontal velocity and length height ratio are presented.更多还原
