摘要： 随着我国城市化进程的加快,餐厨垃圾的量不断增加,污水处理厂的新扩建及升级改造在提高污水处理量的同时也增大了剩余污泥的产量,如何有效处理餐厨垃圾与剩余污泥引起了人们的广泛关注。本文阐述餐厨垃圾与剩余污泥厌氧共消化过程中,脂质、氨氮、盐分、辣椒素、微塑料和抗生素等抑制性物质对厌氧共消化过程稳定性的影响及其机制;总结了通过物理、化学、生物等预处理方法去除抑制性物质,添加生物炭、零价铁等强化性物质,以提高厌氧共消化的效能与稳定性;归纳了在餐厨垃圾与剩余污泥处理中将微生物燃料电池、微生物电解碳捕获、热解、微藻等技术与厌氧共消化技术相结合的耦合技术,从而减少餐厨垃圾与剩余污泥处理过程的碳排放,旨在为未来餐厨垃圾与剩余污泥厌氧共消化处理研究提供技术支撑,实现绿色低碳处理,助力我国早日实现碳达峰、碳中和。

关键词: 餐厨垃圾, 剩余污泥, 厌氧共消化, 强化措施, 碳减排

Abstract: As an important part of municipal solid waste, the outputof food wasteis increasing with the acceleration of urbanization in China. Meanwhile, the construction and upgrading of sewage treatment plants have increased the production of excess sludge. Therefore, the effective treatment of food waste and excess sludge has attracted extensive attention. Firstly, the effects and mechanisms of inhibitory substances such as lipid, ammonia, salt, capsaicin, microplastic and antibiotics on the stability of the anaerobic co-digestion of food waste and excess sludge were expounded. Secondly, it was proposed that the inhibitory substances could be removed by physical, chemical and biological pretreatment methods, and the appropriate amount of biochar, zero-valent iron and other strengthening substances should be added to improve the efficiency and stability of anaerobic co-digestion. The coupling technology combining microbial fuel cell, microbial electrolysis carbon capture, pyrolysis, microalgae with anaerobic co-digestion technology in the treatment of food waste and excess sludge was summarized. The purpose is to reduce the carbon emission in the treatment process of food waste and excess sludge, and finally realize the green and low-carbon treatment.

Key words: food waste, excess sludge, anaerobic co-digestion, strengthening measures, carbon emission reduction
