摘要
针对污水处理厂和人工湿地的不足之处,结合丘陵地带山坡较多的自然地理特征和土壤植被对生活污水中的有机物(BOD、COD)、氮和磷有明显去除作用的特点,以及坡面生态系统对坡面土壤的保护功能,提出了将坡面、土壤、植被和污水相融合,构成一个坡面生态系统,利用此系统对生活污水进行生态处理的想法,并对系统的设计提出了相应的要求。
Based on the deficiency of the managing factory and artificial wetlands, and combining the natural and geographical character in highland which has many hillside with the fimction of the sloping ecosystem, such as the soil and vegetation in the system can deal with the organic substance BOD and COD, nitrogen and phosphorus in domestic water, and the system can protect the soil, the text puts forward the idea of integrating slope, soil, vegetation with domestic water to form a sloping ecosystem which is used for the ecological management of domestic water, and brings forward the corresponding requirement of the system designing.
