31、水中主要污染物为盐类和有机物，蒸发浓缩的基本原理是利用废水加热沸腾后，水和非挥发性的溶解物（盐类，大分子有机物）相分离,甲醇可汽提回收利用。通过蒸发浓缩除盐而使废水得到净化，并提高其可生化性。工艺废水从旋流式薄膜蒸发器顶部的进口沿切线方向流进 ，由于速度很高，离心力很大，因而形成均匀的螺旋形薄膜，紧贴器壁流下，在内壁外层蒸汽夹套的加热下，液膜迅速沸腾汽化。析出的废盐晶和蒸发残渣由椎底排出，蒸发器的二、三次蒸汽通过换热器加热废水，从而节约蒸汽的消耗；液体进入调节池进行后续处理。从夹套中出来的蒸汽再经冷凝器冷却后进入中和调节池进行后续处理。c. 废晶盐、蒸馏残液处理项目工艺废水蒸馏产生的废晶盐和有

34、用受到抑制，难以降解。但在微电解反应条件下，芳香烃类等其它化合物将被迅速分解为无毒性或毒性较小的小分子有机物，提高了废水的可生化性，同时去除了部分的CODcr。水力停留时间为5 h，钢结构，环氧防腐。4絮凝反应器絮凝反应采用涡流反应工艺，具有停留时间充分、反应效果好；水力停留时间为1h，钢结构，环氧防腐。5. 斜板沉淀器斜板沉淀器的优点是停留时间短，沉淀效率高，占地省。设计流量为1m3/h。沉淀段表面负荷为1.0m3/m2h，沉淀时间为2.0h，超高200mm，上清液高度为700mm，沉淀区有效水深为900mm，缓冲层高度为700mm，污泥斗高度为1100mm，沉淀区加装PVC斜板，A3钢结构
35、，环氧防腐。6. 接触氧化塔（PACT）接触氧化池采用鼓风机提供氧气，使微生物能利用污水中的有机污染物作为底料，进行正常的新陈代谢，从而降低污水中有机污染物的浓度。在溶解氧和营养物都充足的情况下，微生物繁殖迅速，生物膜逐渐增厚，溶解氧和污水中的有机物凭借扩散作用，为微生物所利用，从而达到去除污染物的目的。接触氧化池表面呈长方形（内装填料含悬挂填料及生物炭填料），废水从池首端进入，在曝气和水力条件的推动下，混合液均衡地向前流动，并从池尾端流出。接触氧化池任何两个断面都存在有机基质的浓度梯度，因此存在着基质降解动力，BOD降解菌为优占菌，可避免污泥膨胀问题。曝气池采用钢结构，设计流量为24m3/T
36、，有效容积为10m3，水力停留时间10h。保护层高为400mm，有效水深为3600mm，气水比为15：1，需风量为30m3/h。采用盘状曝系统曝气， A3钢结构，环氧防腐。为保证处理效果接触氧化池分两格。7生物炭床反应器(二沉池合建) 为确保处理效果，对排放水进行生物炭床反应器处理，使废水经处理后能稳定达标排放。生物活性炭工艺是一种生化和物化相结合的污水处理工艺，其主要作用是去除水中溶解性的有机污染物，在无溶解氧的条件下，活性炭与污染物质之间属于单纯的吸附作用；在有溶解氧的条件下，微生物利用水中溶解氧得以在炭表面上生长繁殖，降解水中的有机物。由于生物炭工艺结合了生化再生过程，因此活性炭使用周期
37、长，可达3-5年。尺寸为2000mm h2500m(与二沉池合建)，A3钢结构，环氧防腐。8、干化进一步减小污泥体积，使污泥干化，最终外运。外型尺寸为4500mm3500mm1000mm。五、 处理单元构筑物污染物去除分担率污染指标CODcr苯SS甲醇值（mg/l）去除率（%）值（mg/l）去除率（%）值（mg/l）去除率（%）值（mg/l）去除率（%）工艺废水13554-2210-11049-调节池22545-359-1650-1616-厌氧微电解22911035.990148510323.280絮凝沉淀13754021.54059460161.650接触氧化塔550602.1590356.
