凤眼莲水处理池的污染去除雏型算式

尽管凤眼莲水处理池（WHTS）在30年来已被广泛研究，大部份学者从实验室试验，研究各项影响植物生长之参数、建立养份去除模型、拟定雏型算式；但是在实际运行中影响WHTS处理效率的因素很多，包括处理池的设计、运作条件等，各项因素又可能互为表里，所以应用于计算大型的WHTS的常有不足之处；此外，算式应用起来也显得比较繁复。从宏观的角度分析，在特定（经常应用）的范围内的养份去除率可由一条简易的二次雏型算式Y=a＋bx＋cx^2代表，算式中有几个常数是因个别处理池的设计及运作条件而异；采用一些前学者的实验结果及美国WHTS实际运行数据印证出算式准确。

Empirical Formula for Water Hyacinth Treatment Plant

Notwithstanding the fact that Water Hyacinth Water Treatment System(WHTS)has been extensively investigated for near 30 years,most investigators studied in laboratory scale for various parameters affecting the plant growth and developed the models predicating the nutrients removal rates.However,in a realistic plant in operation,factors affecting nutrients removal rates include hyacinth pond design and local operation conditions.Previous empirical formulae proposed appear to be either complicated or not suffi...
