一级水处理装置的数学模型探讨

Mathematics Model of Equalizing Basin Used in Pre-Treatment of Wastewater

污水净化处理系统一般由多级处理构筑物串接在一起 ,其处理效果受来水量和水质的变化影响很大 ,设计合理的水质水量调节构筑物——一级水处理装置尤为重要 .水量调节是水质调节的前提 ,对于冶金企业这类污水循环量大的系统 ,常规调节设计计算方法不能适应 .针对这类系统的特性 ,抽象出污水流量大、变化幅度高、自由出流的一级处理装置调节模型 ,推导出相应水量调节特征方程 .该方程描述了水位、水量变化过程和状态 ,可用于这类工程的设计计算和计算机模拟 .

The wastewater treatment system is usually made up of multi\|stage basins. The treatment efficiency depends mainly on the pre\|treatment and so the design of equalizing basin is very important. The conventional formula cannot be used for designing the basin with a great amount of wastewater intake (e.g. metallurgy wastewater). A new mathematics model is put forward which can be used for designing equalizing basin with a great quantity of intake, a wide range of intake variation, and free outlet. And the model can also well describe the relationship among water level, intake, outtake, equalizing time, and so on.
