Near-natural ecological weir and construction method thereof
The invention discloses a near-natural ecological weir and a construction method thereof. The ecological weir comprises a river bank plant buffer zone, a main weir body, a filler body, a microporous aeration device, a microorganism embedding box, an ecological floating island and an anti-scouring pit. The main weir body is made of raw wood and rockfill, the structure is novel, and the ecological property and the landscape property are high; the filler body structure is provided with three purification units, algae and suspended solids in a water body are filtered out in advance by the algae filtering unit, turbulence of the water body is increased by the oxygenation aeration unit, the dissolved oxygen content of the water body is increased, and the water quality purification capacity is remarkably improved by the biological membrane purification unit through efficient interception, adsorption and degradation of microorganisms; on one hand, the ecological floating island can absorb andadsorb nitrogen and phosphorus-containing substances in water through plant root systems, and on the other hand, the root systems can secrete a large amount of enzymes to promote decomposition of organic matters in the water; the downstream anti-scour pit can effectively reduce scour of water flow to a downstream riverbed, and the pebble cushion layer provides a suitable habitat for fishes.
本发明公开了一种近自然型生态堰及其构建方法，所述生态堰包括河岸植物缓冲带、主堰体、填料体、微孔曝气装置、微生物包埋箱、生态浮岛、抗冲刷坑。本发明主堰体材料由原木及堆石构成，结构新颖，生态性、景观性较强；填料体结构设置三个净化单元，滤藻单元预先过滤掉水体中的藻类及悬浮物，增氧曝气单元增加水体紊动，提高水体溶解氧含量，生物膜净化单元通过微生物高效截留、吸附、降解，显著提高水质净化能力；生态浮岛通过植物根系一方面可以吸收和吸附水中的含氮、磷物质，另一方面根系可以分泌大量的酶来促进水中有机物的分解；下游抗冲刷坑能够有效减轻水流对下游河床的冲刷，且设置的卵石垫层为鱼类提供了一个适宜的栖息地。
