生物脱硫:温和高效降低运营成本的脱硫方法
生物脱硫,也被称作生物催化脱硫,是一种利用微生物或其含有的酶来催化含硫化合物(如H2S、有机硫)的过程,通过这一过程,将硫从化合物中释放出来(转化为S0或单质S)。这是一种低能耗、高效率、对环境友好的新型脱硫技术。
Biological desulfurization, also known as biocatalytic desulfurization, is a process that utilizes microorganisms or their enzymes to catalyze sulfur-containing compounds (such as H2S, organic sulfur). Through this process, sulfur is released from the compounds (converted into S0 or elemental S). This is a new type of desulfurization technology with low energy consumption, high efficiency, and environmental friendliness.
脱硫,是指燃烧前脱去燃料中的硫分以及烟道气排放前的去硫过程。这些处理步骤对于控制和减少大气污染至关重要,尤其是在燃煤发电厂中,烟气中的二氧化硫(SO2)是构成大气环境的主要污染物之一,对人类的健康构成了直接的威胁。
Desulfurization refers to the process of removing sulfur from fuel before combustion and removing sulfur from flue gas emissions. These processing steps are crucial for controlling and reducing air pollution, especially in coal-fired power plants, where sulfur dioxide (SO2) in flue gas is one of the main pollutants that constitute the atmospheric environment and poses a direct threat to human health.
目前,常见的脱硫方法包括湿法脱硫和干法脱硫,这些工艺技术相对成熟,脱硫效率高。然而,它们也面临着设备复杂、能耗高、维护成本昂贵、废水和污泥处置难度大等问题。
At present, common desulfurization methods include wet desulfurization and dry desulfurization, which are relatively mature and have high desulfurization efficiency. However, they also face problems such as complex equipment, high energy consumption, expensive maintenance costs, and difficulty in disposing of wastewater and sludge.
生物脱硫技术则允许微生物“清洁工”悄无声息地潜入烟气中,将那些不受欢迎的硫化合物中和掉,整个过程温和而高效。其工作原理为:在生物滴滤塔装置中,通过“生物还原-生物氧化”联合工艺,将有害的二氧化硫气体转化为无害的、可用于农业生产的生物硫黄,从而达到环保的目的。该技术不仅实现了硫化物的高效转化和单质硫回收,还简化了操作流程,降低了运营成本,提高了生物脱硫效率。
Biological desulfurization technology allows microbial "cleaners" to silently infiltrate into the flue gas, neutralizing unwanted sulfur compounds, and the entire process is gentle and efficient. Its working principle is: in the biological drip filtration tower device, harmful sulfur dioxide gas is converted into harmless biological sulfur that can be used in agricultural production through a combined process of "biological reduction biological oxidation", thus achieving the goal of environmental protection. This technology not only achieves efficient conversion of sulfides and recovery of elemental sulfur, but also simplifies the operation process, reduces operating costs, and improves the efficiency of biological desulfurization.
团队经过无数次的实验,成功筛选并驯化出一批能够“吃掉”硫化物的微生物。这些微生物包括硫酸盐还原菌系列、硫氧化菌系列等,它们是一批拥有自主知识产权的高活性、高耐受性的特种微生物菌株。
After numerous experiments, the team successfully screened and domesticated a group of microorganisms capable of "eating" sulfides. These microorganisms include sulfate reducing bacteria series, sulfur oxidizing bacteria series, etc. They are a group of highly active and tolerant special microbial strains with independent intellectual property rights.
利用自然之力解决环境问题的微生物脱硫技术,展现了基于自然解决方案的卓越典范。这种技术通过利用微生物的天然能力来处理烟气中的硫化物,不仅减少了对传统能源的依赖和使用,同时也大幅度降低了维护和运营的成本。此外,微生物脱硫技术还促进了烟气中硫化物的有效利用,将其转化为有用的化学物质,从而实现了资源的循环利用。这种既环保又经济的解决方案,不仅有助于减轻工业排放对环境的影响,而且推动了可持续发展的步伐,为未来的环境保护工作提供了新的思路和方法。
The microbial desulfurization technology that utilizes the power of nature to solve environmental problems demonstrates an excellent example based on natural solutions. This technology utilizes the natural ability of microorganisms to treat sulfides in flue gas, which not only reduces dependence on and use of traditional energy, but also significantly reduces maintenance and operation costs. In addition, microbial desulfurization technology also promotes the effective utilization of sulfides in flue gas, converting them into useful chemicals and achieving resource recycling. This environmentally friendly and economical solution not only helps to reduce the impact of industrial emissions on the environment, but also promotes the pace of sustainable development, providing new ideas and methods for future environmental protection work.
