Description
技术领域technical field
本发明属于本微生物燃料电池应用领域，特别涉及一种利用自呼吸式微生物燃料电池产电除污的方法。The invention belongs to the application field of the microbial fuel cell, and particularly relates to a method for generating electricity and decontamination by using a self-breathing microbial fuel cell.
背景技术Background technique
微生物燃料电池是借助多种微生物将有机物中的化学能直接转化成电能的装置。相比传统燃料电池，微生物燃料电池利用微生物代替昂贵的化学催化剂，且能在产生能源的同时净化污水，发展前景巨大。微生物燃料电池主要由阳极室、阴极室以及中间的隔膜（多为质子交换膜）组成。微生物燃料电池的基本工作原理是：在厌氧环境下，阳极室内悬浮的微生物将复杂的大分子有机物分解为小分子有机物，附着在阳极表面的微生物群落进一步分解小分子有机物和部分大分子有机物，同时产生电子和质子，其中电子通过不同方式传递到阳极，并经由外电路到达阴极，而质子则通过中间质子交换膜到达阴极室，氧化剂(一般为氧气或铁氰化钾溶液) 在阴极与电子和质子发生还原反应，构成完整的电流回路。A microbial fuel cell is a device that directly converts chemical energy in organic matter into electrical energy by means of a variety of microorganisms. Compared with traditional fuel cells, microbial fuel cells use microorganisms instead of expensive chemical catalysts, and can purify sewage while generating energy, with great development prospects. A microbial fuel cell is mainly composed of an anode chamber, a cathode chamber and a diaphragm in the middle (mostly a proton exchange membrane). The basic working principle of microbial fuel cells is: in an anaerobic environment, microorganisms suspended in the anode chamber decompose complex macromolecular organic matter into small molecular organic matter, and the microbial community attached to the surface of the anode further decomposes small molecular organic matter and some macromolecular organic matter. Electrons and protons are generated at the same time. The electrons are transferred to the anode in different ways and reach the cathode through the external circuit, while the protons reach the cathode chamber through the intermediate proton exchange membrane. A reduction reaction occurs with protons to form a complete current loop.
但现阶段微生物燃料电池产能低下，不足以实际应用和推广。虽然随着微生物燃料电池电极和反应器构型的不断改进，其单体能量密度增长迅速，但是仍然存在以下问题：阳极电极比表面积小，不利于微生物的附着和生长；实验室多外加磁力搅拌装置提高电池性能，但是这无疑增加耗能，且实际应用中不可能外加磁力搅拌装置；阴极室多曝气以促进还原反应，但增加成本；质子交换膜成本太高，且易增加电池内阻；电池多为间歇工作，需周期性更换废水，不利于实际应用；新型电池反应器结构复杂且多不可扩充。However, the production capacity of microbial fuel cells is low at this stage, which is not enough for practical application and promotion. Although with the continuous improvement of microbial fuel cell electrode and reactor configuration, its monomer energy density has increased rapidly, but there are still the following problems: the specific surface area of the anode electrode is small, which is not conducive to the attachment and growth of microorganisms; magnetic stirring is often used in laboratories The device improves battery performance, but this undoubtedly increases energy consumption, and it is impossible to add a magnetic stirring device in practical applications; more aeration in the cathode chamber promotes the reduction reaction, but increases the cost; the cost of the proton exchange membrane is too high, and it is easy to increase the internal resistance of the battery ; Most of the batteries work intermittently, and the waste water needs to be replaced periodically, which is not conducive to practical application; the structure of the new battery reactor is complex and most of them cannot be expanded.
