Abstract

Using a composite ecological remediation system for the long-term field application has been remaining a challenge. To cope with this problem, we fabricated a mussels-bacteria stereo integrated (MBSI) system deployed on a river bank to improve the river water quality. The MBSI system was operated for more than 4 months, and it was found that the turbidity, COD and TN of river water decreased significantly (P < 0.05) after the MBSI system treatment. The mussels layer was dominated by fermentation bacteria like Cetobacterium (7.6%), while ammoxidation bacteria of norank_NS9_marine_group (9.7%), denitrication bacteria of Thauera (9.4%) and anammox bacteria of Pirellula (3.7%) predominated in the immobilization microorganisms, demonstrating that the major responsibility was COD removal for mussels and nitrogen removal for immobilization bacteria. In summary, mussels and bacteria (immobilized) reinforced the synergistic effect, the combination of which provided a simple and feasible system for the improvement of river water quality and a promising tool for the engineering practice.

贻贝-细菌立体一体化系统在污染河道水质改善中的现场应用

使用复合生态修复系统进行长期的野外应用一直是一个挑战。为了解决这一问题，我们制作了一种贻贝-细菌立体集成（MBSI）系统，部署在河岸上，以改善河流水质。MBSI系统运行4个多月后，发现MBSI系统处理后的河水浊度、COD和TN均显著降低（P < 0.05）。贻贝层以发酵菌Cetobacterium（7.6%）为主，固定化微生物以norank_NS9_marine_group的氨氧化菌（9.7%）、Thauera的反硝化菌（9.4%）和Pirellula的厌氧氨氧化菌（3.7%）为主，说明对贻贝的COD去除和固定化菌的氮去除是主要作用。综上所述，贻贝与细菌（固定化）强化了协同效应，两者的结合为改善河流水质提供了一种简单可行的系统，也为工程实践提供了一种很有前景的工具。

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
