The invention relates to a composite lightweight concrete ecological floating island. A lightweight concrete bed body, floating regulator, fiber bionic grass floating regulating device is arranged on the upper bed body, fiber bionic grass set in the bottom of a bed body, a bed body with concrete anchor and elastic cable fixed in the water, between the bed body and the bed body are connected by elastic material, the interior of the bed a hollow cavity and closed down through the cavity, light filler, holes are arranged on the bottom of steel wire mesh, the cavity filled with inorganic lightweight materials and cultivated plants; the water floating regulator made of PVC pipe or PE pipe; fiber bionic grass which is composed of a mesh or flaky or fibrous the geotextile is made; the inorganic lightweight material for ceramic or vermiculite. The invention can effectively avoid the aging of common organic carrier and two pollution phenomenon; is favorable to decomposition of organic matter, bioremediation is helpful to solve the water; in water by floating island water level fluctuation is difficult to fix the problem; but also to beautify the water and fire spread protection embankment effect.
【技术实现步骤摘要】
本专利技术涉及一种生态浮岛，特别是一种以轻质混凝土为主体的复合轻质生态浮 岛，是一种水质处理装置。
技术介绍
生态浮岛是指将植物种植于浮于水面的床体上，利用植物根系吸收水体中污染物 质，同时植物根系附着的微生物降解水体中污染物。生态浮岛载体可分为三大类第一类是植物根茎载体，这种载体最早只是利用漂浮植物，后逐渐发展为直接在富营 养化水体中，种植挺水植物和沉水植物，如玉溪市环科所在星云湖隔河口湖湾围养20万 m2水葫芦去除蓝藻(李荫玺，李文朝，杨逢乐，等.星云湖隔河湖湾飘浮植物除藻技术研究 .云南环境科学，2006，27 (3) 42-44)，但由于水生植物容易过度繁殖和老化死亡， 收获和处理不易，且此类水生植物如水葫芦等为入侵性物种，因而该技术不能直接应用于 较大规模的富营养化湖泊的治理。第二类是有机高分子载体，由于有机高分子材料的制作工艺成熟，价格低廉，安 装、运输方便，如中国专利技术专利CN1609018A公开的复合立体生物浮床，以竹子制成网格状 立体框架，上层节点安放植物，下层悬挂线形弹性材料；也有利用白色泡沫塑料作为浮岛载 体(曹勇，孙从军.生态浮床的结...
