焦化废水生化处理及沉淀池
摘要：
本发明提供了一种焦化废水生化处理及沉淀池，所述焦化废水生化处理及沉淀池包括：缺氧混合区（1）；缺氧池第一条廊道（3）；缺氧池第二条廊道（4）；第一端墙（40）；第一气升泵（5）；好氧混合区（6），通过第一端墙（40）连接所述缺氧池第二条廊道（4）；好氧污泥沉淀区（12）；好氧池第一条廊道（7）；好氧池第二条廊道（8）；好氧池第三条廊道（11），所述好氧池第三条廊道（11）与所述好氧池第二条廊道（8）连通形成折弯形，并且所述好氧池第三条廊道（11）连通所述好氧污泥沉淀区（12），所述好氧池第三条廊道（11）与所述好氧污泥沉淀区（12）连接形成折弯形。本发明中大大的提高了好氧污泥和硝化液的回流比，抗冲击能力强。
摘要（英）：

The invention provides a coking wastewater biochemical treatment and sedimentation tank which comprises an anoxic mixing zone (1), a first anoxic tank gallery (3), a second anoxic tank gallery (4), a first end wall (40), a first air lift pump (5), an aerobic mixing zone (6), an aerobic sludge sedimentation zone (12), a first aerobic tank gallery (7), a second aerobic tank gallery (8) and a third aerobic tank gallery (11), wherein the aerobic mixing zone (6) is connected with the second anoxic tank gallery (4) by the first end wall (40); and the third aerobic tank gallery (11) is communicated with the second aerobic tank gallery (8) to form a bending shape, communicated with the aerobic sludge sedimentation zone (12), and connected with the aerobic sludge sedimentation zone (12) to form a bending shape. The tank greatly increases a reflux ratio of aerobic sludge to a nitration solution, and is high in shock resistance.
