污泥厌氧产酸发酵的影响因素及研究进展
|
摘要
污泥水解酸化是将污泥厌氧消化控制在厌氧反应的前两个阶段,污泥水解酸化上清液可作为内碳源用于生物脱氮除磷工艺。影响污泥水解酸化的因素有温度、pH、ORP、SRT、HRT、污泥性质以及预处理。其中预处理包括:超声预处理、碱预处理、热预处理、添加表面活性剂等。不同的影响因素和预处理对污泥水解酸化效果的影响较大,本文重点阐述了其具体的影响规律。
Biological hydrolysis and acidification of sludge are controlled under the first two stages of anaerobic reaction.The volatile fatty acid of sludge hydrolysis and acidification can be used as an internal carbon source for the removal of nitrogen and phosphorus. Factors affecting the hydrolysis and acidification of sludge include temperature, pH, ORP, SRT, HRT, sludge properties, and pretreatment. And the pretreatment includes ultrasonic pretreatment, alkali pretreatment, thermal pretreatment and adding surfactant. The effect of sludge hydrolysis and acidification is considerably affected by different factors. Some specific factors are summarized and analyzed.
