摘要:

剩余污泥中存在大量的微生物, 微生物的细胞质富含丰富的有机质(包括糖、蛋白质和脂肪等),但微生物的细胞质被细胞壁包裹, 限制了污泥的厌氧发酵。想要改变污泥中有机物的可利用性, 必须采用适当的预处理技术, 破坏细菌的细胞壁使有机质溶出, 以利于后续厌氧发酵产氢。系统介绍了物理(微波、超声波和热预处理)、化学(酸、碱预处理)、生物(酶预处理)等预处理方式及其他因素对污泥厌氧发酵产氢率的影响。

Abstract:

A large number of microorganisms exist in excess sludge. Microbial cytoplasms are rich in organisms, including sugar, protein, fat, etc., but they are wrapped by the cell walls, which limit anaerobic fermentation. If the availability of organisms in sludge needs to be changed, it is necessary to use appropriate pretreatment techniques, destroy the cell walls of bacteria, and dissolve out the cytoplasm, in order to be advantageous to the subsequent anae- robic fermentation for hydrogen production. The effects of various pretreatment methods, such as physical ones(mi- crowave, ultrasound and thermal pretreatments), chemical ones(acids pretreatment, alkali pretreatments), biological ones(enzymatic pretreatment), and other factors on the hydrogen production rate by sludge anaerobic fermentation are introduced systematically.

Key words: microorganism, anaerobic fermentation, pretreatment, hydrogen production rate
