Key Difference – Bioremediation vs Phytoremediation
Environmental pollution can be controlled by the use of biological organisms such as microorganisms, plants etc. They do have inherent capabilities of degradation or transformation of contaminants into non-hazardous substances. These natural capabilities are explored by humans to accelerate the cleanup processes.生物修复是人类为使用生物生物(尤其是微生物)清洁环境而开发的整体过程。植物修复是生物修复的子类别,仅使用绿色植物清洁环境。这就是生物修复和植物修复之间的关键区别。

What is Bioremediation?
生物修复is a method in which environmental pollution is controlled using biological systems. It is implemented by people to speed up the cleaning process without affecting the environment and the organisms. The main objective of the bioremediation is to convert toxic or hazardous substances in the environment into non-toxic or less hazardous substances by biological means. Microorganisms are the main concern when implementing these methods since they are easy to use and exhibit diverse reactions. Bioremediation is used to treat contaminated soils, lands, water etc. There are different strategies in bioremediation: use of genetically modified microorganisms, use of native microorganisms, phytoremediation, biostimulation, bioaugmentation etc.
What is Phytoremediation?
植物具有从其生长基质中吸收化学物质的显着能力。在这种情况下,植物内部分布的根系和运输组织在植物中造成了贡献。植物修复是一种通过使用绿色植物来清除环境中污染物的技术。在植物,土壤,污泥,沉积物和水的帮助下,在植物修复中以生物学手段清洁被有机和无机污染物污染的水。因此,植物修复被认为是一种基于环境的,基于自然的方法,因为它不会损害或添加毒素到环境中。参与补救的植物可以分类如下。
- 植物降解(phytotransformation)- 分解植物在植物组织中通过代谢吸收的污染物。
- 植物刺激或根茎降解- 通过通过释放的根部渗出物(如糖,醇,酸等)刺激微生物生物降解,使植物根际污染物降解。
- Phytovolatilization- 植物从土壤中吸收污染物,并通过蒸腾以改良形式释放到大气中。
- 植物萃取(phytoaccumulation)——烟机tion of metals such as nickel, cadmium, chromium, lead etc. from the soil into the above ground plant tissues and dislocation them from the environment.
- Rhizofiltration– Adsorption of the contaminants into plant roots from the soil solution or ground water.
- Phytostabilization– Certain plants immobilise contaminants through absorption by roots, adsorption onto root surface and precipitation within the area of plant roots.
Plants are grown in the contaminated site for a particular time period. When plants are grown, they absorb nutrients together with the contaminants from the growth matrix of the plant. The root exudates of the plants enhance the microbial activity in the rhizosphere area and accelerate the biodegradation of the contaminants by the microorganisms. Both means facilitate the removal of the contaminants from the environment. At the end of the remediation process, the plants can be harvested from the site and processed.
植物具有处理环境中累积污染物的固有能力。不同的植物品种显示出不同的吸收和降解电位。一些植物能够从土壤中吸收重金属,这是从环境中去除重金属的巨大用途。植物修复是清洁农药污染,原油污染,多芳烃污染和溶剂污染的流行方法。该技术还适用于河流河流管理人员,以控制河水中的污染物。

摘要 - 生物修复与植物修复
生物修复使用微生物和植物将污染物分解成较少的有害化合物。这是人们实施的环保过程,以净化环境并减少威胁。植物修复是一种使用绿色植物的生物修复技术。能够转化或降解污染物的植物用于清洁环境。它是一个原位生物修复方法是具有成本效益和基于太阳能的技术的生物修复方法。这是生物修复和植物修复之间的差异。
