摘要

针对黄土高原发展坡地高效农业面临的缺水及水源水质差而传统微型沉沙池效率低

清淤困难等问题

基于调控降雨径流

高效利用水土资源的理念

根据生物与物理净化的不同特点

设计出一套生态环保型高效滤清净水系统并进行了试验验证。结果表明

能源牧草柳枝稷作为植被过滤带与滤清池组合系统

对泥沙和总磷最大拦截效果分别达到98.62%和93.6%

对化学需氧量(COD)的最大拦截效果达到56%

说明柳枝稷植被过滤带对泥沙和污染物的拦截效果明显。并在此基础上再铺设不同粒径砂石的滤清池

只需拦截植被过滤带下来的柴草

使布置大幅简化

造价大幅降低。该系统可广泛应用于黄土高原坡地高效农业水源净化系统。

Abstract

The slope land efficient agriculture developments are facing with the problems such as water shortage and poor water quality in the Loess Plateau region. Based on the concept of rainfall runoff regulation and water and soil resources efficient utilization

an ecological environmental protection and efficient water filter system was designed through taking account of different characteristics of biological and physical purification

and was verified using experiment measured data. Results showed that the maximum total phosphorus and sediment interception effect of the filter system which used energy grass(Panicum virgatum) as vegetation filtering belt combined with filtration pool system reached 93.6% and 98.62% respectively

and the biggest interception effect of COD(chemical oxygen demand) reached 56%. Panicum virgatum filtering belt in the system had an obvious interception effect for sediment and pollutant. The sand filtration pool with different particle size combination had higher interception efficiency for straw under the vegetation zone

and it made the system greatly simplified

and reduced the cost significantly. The system was able to be used for high-efficient agricultural water resource purification in the Loess Plateau.
