IC厌氧反应器

IC 厌氧反应器，即内循环厌氧反应器，由2层UASB 反应器串联而成。 其由上下两个反应室组成。 在处理高浓度有机废水时，其进水负荷可提高至20-40kgCOD/(m3.d)。 与 UASB 反应器相比，在获得相同处理速率的条件下，IC 厌氧反应器具有更高的进水容积负荷率和污泥负荷率，IC 厌氧反应器的平均升流速度可达处理同类废水 UASB 反应器的20倍左右。 广泛应用于高浓度有机污水处理、难降解有机废水的预处理以及废水的脱氮除磷等领域。 
The IC anaerobic reactor, or IC anaerobic, is composed of two UASB (Upflow Anaerobic Sludge Blanket) reactors connected in series. It consists of two reaction chambers, an upper one and a lower one. When treating high-concentration organic wastewater, the influent load can be increased to 20-40 kgCOD/(m³.d). Compared to the UASB reactor, the IC anaerobic reactor achieves higher influent volumetric loading rate and sludge loading rate under the same treatment rate conditions. The average upflow velocity of the IC anaerobic reactor can reach about 20 times that of the UASB reactor for treating similar wastewater. It is widely used in the fields of high-concentration organic wastewater treatment, pretreatment of refractory organic wastewater, and nitrogen and phosphorus removal from wastewater.
