摘要:
针对活性覆盖材料吸附饱和失效和沉水植物在光照较弱的水体底部难以生存的问题,在污染底泥沉水植物与活性覆盖材料联合修复技术的基础上,研发一种可调节式富营养化水体污染底泥覆盖床装置,并开展室内静态模拟实验.结果表明:实验历时25 d,在苦草种植密度为30 株·m-2,黑藻种植密度为8 丛·m-2,沸石和活性炭混合覆盖强度均为1 kg·m-2的条件下,基于沉水植物(苦草+黑藻)和活性覆盖材料(沸石+活性炭)联合的可调覆盖床系统对水体中氨氮削减率及高锰酸盐指数削减率分别达到98.78%,51.05%,可有效削减水体中氨氮和有机物的负荷.
Abstract:
Facing with the problems of the saturation and the lack of efficacy of the active capping materials and the low survival rate of submerged macrophytes at the bottom of water where sunlight can barely reach, an adjustable capping bed for eutrophication pollution sediment was developed based on the joint remediation technology of submerged macrophytes and active capping materials, and the static simulation experiment was carried out indoors. The research results show that the simulation experiment, which lasted 25 d, was conducted with the adjustable capping bed device under the conditions that the planting density of vallisneria natans was 30 clusters·m-2, the planting density of hydrilla verticillata was 8 clusters·m-2, and the mixed coverage density of zeolite and activated carbon was 1 kg·m-2. Under these conditions, the reduction rates of ammonia nitrogen and permanganate index were as high as 98.78% and 51.05% respectively when the adjustable capping bed system consisted of submerged macrophytes(vallisneria natans+hydrilla verticillata)combining with active capping materials(zeolite+activated carbon), which demonstrates that this system can reduce the load of ammonia nitrogen and organic matter in water effectively.
