Description
技术领域technical field
本实用新型属于环保设备及应用，具体涉及一种电化学改进的生物过滤塔净化装置。The utility model belongs to environmental protection equipment and applications, in particular to an electrochemically improved biological filter tower purification device.
背景技术Background technique
挥发性有机化合物(VOCs)挥发性有机物是一类常见且非常重要的大气污染物，主要由苯类、醇类、醛类、烃类等上千种物质组成。其处理主要分为回收技术和分解技术，回收技术包括吸收法、吸附法、冷凝法和膜分离处理技术等，可实现有机废物的回收，但是回收的纯度难以保证，并且处理有机废物的材料再生困难，容易产生二次污染。分解法包括热焚烧法、化学氧化法、催化氧化法和等离子体分解法，生物过滤法等。其中生物过滤工艺是微生物以VOCs为碳源和能源，在适宜的环境条件下通过自身的新陈代谢作用将VOCs转化为一部分细胞组成物质、二氧化碳(CO2)、水(H2O)未完全降解物质和小分子无机物质，与其他物理化学方法相比具有高效、节能、投资成本和运行费用低、操作简单、使用安全等优势，是一种能源节约、环境友好型技术，符合我国节能减排和发展低碳经济的政策要求，因此，在实际工程应用中与传统的物理化学方法相比极具竞争力。Volatile Organic Compounds (VOCs) Volatile organic compounds (VOCs) are a common and very important class of air pollutants, mainly composed of thousands of substances such as benzene, alcohols, aldehydes, and hydrocarbons. Its treatment is mainly divided into recovery technology and decomposition technology. The recovery technology includes absorption method, adsorption method, condensation method and membrane separation treatment technology, etc., which can realize the recovery of organic waste, but the purity of recovery is difficult to guarantee, and the material for processing organic waste is regenerated. It is difficult and prone to secondary pollution. Decomposition methods include thermal incineration, chemical oxidation, catalytic oxidation, plasma decomposition, and biological filtration. Among them, the biological filtration process is that microorganisms use VOCs as carbon source and energy, and convert VOCs into a part of cell constituent substances, carbon dioxide (CO 2 ), and water (H 2 O) incompletely degraded substances through their own metabolism under suitable environmental conditions. Compared with other physical and chemical methods, it has the advantages of high efficiency, energy saving, low investment and operating costs, simple operation, and safe use. It is an energy-saving and environment-friendly technology. The policy requirements for developing a low-carbon economy are, therefore, highly competitive with traditional physical-chemical methods in practical engineering applications.

In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inside", "outside", "clockwise", "counterclockwise" and other indications of orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, only for the convenience of describing the present utility model and The description is simplified rather than indicating or implying that the device or element referred to must have a particular orientation, be constructed and operate in a particular orientation, and therefore should not be construed as limiting the invention.
在本实用新型中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。In the present invention, unless otherwise expressly specified and defined, a first feature "on" or "under" a second feature may be in direct contact with the first and second features, or the first and second features through an intermediary indirect contact. Also, the first feature being "above", "over" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is level higher than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature has a lower level than the second feature.
以上对本实用新型做了示例性的描述，应该说明的是，在不脱离本实用新型的核心的情况下，任何简单的变形、修改或者其他本领域技术人员能够不花费创造性劳动的等同替换均落入本实用新型的保护范围。The present invention has been exemplarily described above. It should be noted that, without departing from the core of the present invention, any simple deformations, modifications or other equivalent replacements that can be performed by those skilled in the art without any creative effort will fall into place. into the protection scope of the present invention.
