摘要:助剂废水是一种高浓度难降解有机废水，以催化湿式氧化（CWAO）为主体的CWAO-UASB-AOA-接触氧化-混凝沉淀工艺能够对其进行有效降解。在CWAO工业化装置设计中，床层温升（Tg）和换热器总传热系数（K）是换热器设计的2个重要参数。采用Aspen Plus对CWAO过程进行稳态模拟，Aspen Plus对Tg模拟结果同分布式控制系统（DCS）实测结果相对误差在±2.0%以内。根据计算结果可知，K为800 W · (m2 · °C)-1。结合K和Tg可以用来估算换热面积，进而指导CWAO过程系统工程的工业化设计。

Abstract:Auxiliary wastewater is a kind of wastewater containing high-concentration and hard-degraded organic pollutants. Catalytic wet air oxidation (CWAO) is the main process of CWAO-UASB-AOA-contact oxidation-coagulation method, which can effectively treat hard-degraded organic pollutants in auxiliary wastewater. In this CWAO industrialization apparatus, the temperature gradient between the reactor inlet and outlet (Tg) and heat transfer coefficient (K) are two important parameters for heat exchanger design. To this end, we carried out the steady-state simulation of CWAO process by Aspen Plus, and revealed that the relative error Tg of between the simulation and testing results of distributed control system (DCS) was less than 2.0%. Then, the K factor was calculated to be 800 W · (m2 · °C)-1. As a consequence, the heat exchanger area was readily estimated in term of Tg and K, and then provided an insightful engineering design guideline of CWAO industrialization system.
