摘要/Abstract

摘要： 生态浮床作为一种常规治理技术得到了广泛使用,但其只能修复表层富氧水体,对下层缺氧水体的修复能力有限.本研究针对实际黑臭水体的修复需要,设计了潜水式生态介质箱(潜水组),并以传统的生态浮床(浮床组)为对照进行对比试验,研究修复前后黑臭水体的水质变化,考察了水生植物的生长状况及N、P积累能力.结果表明: 随着修复时间的延长,两组处理对各污染物的去除率均逐渐升高,其中潜水组去除全氮(TN)、铵氮(NH₄⁺-N)、全磷(TP)的能力优于浮床组,但其去除化学需氧量(COD_Mn)的能力稍逊;潜水组植物(苦草)的生长状况优于浮床组植物(菖蒲),且苦草对水体中TN、TP的吸收积累能力和去除贡献率均优于菖蒲;此外,苦草的质膜透性、丙二醛和叶绿素含量均低于菖蒲,说明苦草更适于在黑臭水体中生长,该潜水式生态介质箱是新型的一体化原位修复装置,更适用于黑臭水体的修复实践.

Abstract: As a conventional technology, the ecological floating bed has been widely used to repair waste water body. However, it can only repair the surface oxygen-enriched water, and has limited ability to repair the lower anoxic water. To meet the needs of the restoration of black and odorous water body, we designed a submersible ecological media box (submerged group) and compared it with traditional ecological floating bed (floating bed group). Water quality of black and odorous water before and after the restoration was examined, with the growth status of aquatic plants and the accumulation ability of N and P being investigated. The results showed that with the prolongation of repairing time, the removal rate of each pollutant increased gradually in both treatments. The removal ability of the submerged group for TN, NH₄⁺-N, TP was better than that of the floating bed group, but its ability to remove COD_Mn was slightly inferior than that of the floating bed group. Plants (Vallisneria natans) in the submerged group grew better than that in the floating bed group (Acorus cala-mus), with similar patterns of the absorption and accumulation capacity and removal rate of TN and TP. In addition, the plasma membrane permeability and malondialdehyde content of V. natans were lower than that of A. calamus and the chlorophyll content of A. calamus was higher than that of V. natans, indicating that V. natans is more suitable for planting in black and odorous water bodies. Thus, the submersible ecological media box is a new in-situ integrated remediation device, which is more suitable to repair the black and odorous water.
