THE USE OF DYNAMIC METHOD TO ANALYZE MODEL POND

To treat high density synthetic leather waste water, the author used static and dynamic simulated test to analyze the operation of model pond. Because of the limitation of classic static and dynamic experience on analyzing dynamic biological decomposition reaction (DBDR), thc author suggested a new method- Section Initial Velocity Method. The actual experiment proved that reaction progression is changeable and may be increased in the direction of water flow in the model pond. And the change range is between 0-2.5.

基于EFDC模型的湿地生物塘水质净化效果模拟与优化设计

为研究湿地不同生境生物塘水质净化效果,筛选最佳生境的设计方案,以山东省鱼台县惠河湿地项目为背景,基于环境流体力学模型(EFDC模型),建立惠河湿地范围内的水动力、水质数学模型,并根据生物塘水动力、生物特征和物理形态等因素构建目标函数,进行综合赋分,对湿地中生物塘进行优化设计。结果表明:不同生境生物塘对水质有不同程度的改善作用;水体交换程度适当,生物丰富度大,岸线长,偏离主流的生物塘对水质的净化效果佳。研究筛选出的生物塘生境可为湿地修复与水质改善工程提供参考。
