水污染的计算机模拟

本文给出了水源污染过程的计算机模拟方法.建立了水污染方程.提出了水污染微分方程组中各系数的实验确定办法.本模拟适用于水库之类的准封闭水系.也适用于有源有漏的一段河道,不要求进水量和出水量相等.污物种类的多寡不受限制.可以模拟只有本底污染的水源的人为污染过程,也可以模拟已污染水源的再污染或净化过程.模拟时间的长短任意.模拟的结果,除综合结论外、还列表输出水体的含氧浓度及若干种主要无机污物(或难降解的有机污物)的积累浓度,以及它们的坐标式变化曲线.

COMPUTER SIMULATION OF WATER POLLUTION

Computer simulation of water pollution is studied in this paper. The equations have been given. The experimental methods for coefficients in differential equations of water pollution have also been proposed.This kind of simulation suits to quasi-closed systems, for example, reservoir, and also a reach of a river. Flow-in volume of water is not necessarily equal to flow-out volume. It can be applied to different kinds of wastewater. It is able to simulate not only polluting process by man of a water source, but also re-polluting or-purifying process of a polluted water source. Simulated time is arbitrary. Results obtained show that in addition to general conclusions there are tabulation of dissolved oxygen and cumulative concentration of main inorganics (or refractory organics), and curve printed in coordinate paper.A simulation program with CROMEMCO-BASIC language has been provided and executed with examples.
