Ecological interception weir
The invention relates to an ecological interception weir. The ecological interception weir comprises a water channel, an overflow weir and a silt collecting device. The water channel is arranged in the farmland and used for allowing silt mixed fluid in the farmland to flow into the water channel in rainy days; the overflow weir is arranged in the water channel, the overflow weir is arranged at the bottom of the water channel, and the two side walls of the overflow weir make contact with the inner side wall of the water channel, so that the silt mixed fluid entering the water channel is gathered between the water inlet end and the overflow weir, granular silt is precipitated, sediment attached with fertilizer and other substances is prevented from flowing into a lake together under the cooperation of water flow to cause lake pollution, and accumulation caused by the fact that a large amount of the sediment flows into the lake can be avoided. In addition, the silt collecting device is further arranged in the water channel and used for collecting silt deposited at the bottom of the water channel, so that nutrient substances in the silt are extracted and recycled.
本公开涉及一种生态截留堰，包括水渠、溢流堰以及泥沙收集装置；水渠设于农田内用于供下雨时农田内的泥沙混合流体流至水渠内；水渠内设有溢流堰，且溢流堰设于水渠的底部，溢流堰的两侧壁与水渠的内侧壁接触，使得进入至水渠内的泥沙混合流体聚集在入水端与溢流堰之间并沉淀出颗粒状的泥沙，以防止附着肥料等物质的泥沙在水流的协同下一同流入湖泊造成湖泊污染，且可以避免泥沙大量涌入湖泊中造成堆积。此外，水渠内还设置有泥沙收集装置，用于将水渠底部沉淀的泥沙进行收集，以提取泥沙中的营养物质以循环再利用。
