摘要
以活性碳和陶瓷颗粒为载体粒子,采用快速排泥挂膜法启动实验,在反应器的运行过程中逐渐加大进气量及进水量,直至出水COD浓度达到一个较低水平。分别考虑了进水COD浓度、空气流量、废水流量、容积负荷四个因素对COD去除率的影响。结果表明:当系统运行到第13 d时,COD的去除率达到了一个较大值,并趋于稳定。
Taking active carbon and ceramics grain as vector particles, using the method of fast discharging sludge and forming biofilm, the inlet air and wastewater were enlarged gradually until the concentration of COD of outlet reach the low level. COD removal ability was affectted by four kinds of factors, including COD concentration, air and wastewater flow, and volume load. The results showed that COD removal effect had a bigger value and tended towards stability, at the thirteenth day.
