采用厌氧膨胀颗粒污泥床(EGSB)处理葡萄糖废水,研究进水COD浓度对污泥颗粒化的影响.实验结果表明:随着进水COD浓度从2 000 mg/L上升到10 000 mg/L,传质过程中进入颗粒内部的营养量逐渐增加,促进污泥颗粒化,颗粒直径也随之增大;进水浓度剧烈变化对反应器造成很大冲击,引起细菌生长过快,污泥结构松散,沉降性能下降,COD去除率和产气率降低.
- Abstract:
-
Anaerobic expansion granular sludge bed (EGSB) was used to treat glucose wastewater to study the effect of influent COD concentration on sludge granulation. The experimental results show that as the COD concentration of the influent water increases from 2 000 mg/L to 10 000 mg/L, the amount of nutrients entering the particles during mass transfer gradually increases, which promotes the granulation of sludge and increases the particle diameter. The drastic change of the influent concentration has a great impact on the reactor, causing excessive bacterial growth, loose sludge structure, decreased sedimentation performance, and reduced COD removal rate and gas production rate.
