摘要
北方河流多数为季节性河流,河流支流多,水量较小,季节变化大,丰水期防洪问题十分突出,且水域内外存在着严重的生态环境问题,从而极大制约了临河城市经济的可持续发展。作为典型北方河流,渭河流域皂河水在经过规划的污水处理厂净化后,出水达到设计中规定的一级B排放标准,但仍然无法满足景观水体的要求。该研究针对皂河的具体情况设计了一套生态治理方案,以期实现对其生态治理与修复,最终既满足受纳水体对水质的要求,又实现水体的生态提升、景观提升功能,不仅可以对污染严重的皂河进行治理,同时也为以后更加深入地研究北方河流治理与修复进行有益的探索。
Most of rivers are seasonal in North China.There are many features like many tributaries,little water,seasonal changes,the prominent flood control problem of abundant water period,and the serious problem of ecological environment in the waters,which greatly restricts the sustainable development of the city economy.As a typical North River,after the treatment of sewage plant the water of Zaohe River can reach the GB18918-2002 1 B discharge standard which is appointed by the design,but still can not meet the requirements of landscape water.This paper designs a set of ecological management scheme according to the specific condition of Zaohe River,in order to realize the ecological management and restoration.Ultimately it can not only meet the water quality requirements of receiving water.Meanwhile the water can get ecological improvement and landscape promotion.It can not only manage the serious pollution of Zaohe River,but also explore and do more in-depth study of ecological management and water restoration in North Rivers.
