某造纸厂废水处理设计

摘要

本设计内容为造纸废水处理设计。根据国家提出的排放标准进行处理废水，总设

计的进水为 5000 t/d。进水中 COD 6000-8000mg/L，SS 2000-3000mg/L，氨氮 30-50mg/L，

出水要求 COD 浓度小于 300mg/L，SS 小于 70mg/L，氨氮小于 15mg/L，pH 在 6-9 范

围内。

在某个构筑物单独处理中，主要需要完成其平面图剖面图加上一部分详图。污水

的处理按照各构筑物的布置进行处理：污水通过格栅，调节池，UASB，中沉池，A/O

工艺,絮凝沉淀池。污泥的主要的处理流程为：从中沉池 UASB 等构筑物中排出的污泥

进入浓缩池，然后进入脱水机房，UASB 和 A/O 中的污泥储存在浓缩池内，达到一定

容量到脱水机房，最后外运处置。

UASB 工艺具有良好的降低 COD 负荷的功能，A/O 工艺能去除污水中的氨氮。

ABSTRACT

The design content for the papermaking wastewater treatment design. Wastewater

treatment is carried out according to the emission standards proposed by the State. The

total water intake is 5000 t / d. The COD concentration is less than 300mg / L, the SS is less

than 70mg / L, the ammonia nitrogen is less than 15mg / L, the pH is in the range of 6-9

Within range.

In a separate structure of the building, the main need to complete the plan section

with a partial view. Sewage treatment in accordance with the layout of the structure to

deal with: sewage through the grille, regulating pool, UASB, in the pool, A / O process,

flocculation sedimentation tank. The main sludge treatment process is: from the sink pool

UASB and other structures in the sludge discharged into the condensate pool, and then

into the dehydration room, UASB and A / O in the sludge storage tank, to a certain

capacity to the dehydration room, The final handling of disposal.

UASB process has a good function to reduce the COD load, A / O process can remove

ammonia in the sewage.

Keywords: papermaking wastewater, UASB process, A / O process 1
