摘要:
随着水质净化厂处理标准的逐步提高，对净水厂的建设和运行水平提出了稳定、低碳和节能等要求。精准供氧已成为净水厂建造时的常规配置，为保证充分发挥其作用，需对净水厂的水量、水质变化进行估计，并采取适当的供氧设备配置。某水质净化厂采用全地埋式设计，主要出水指标执行《地表水环境质量标准》（GB 3838—2002）准Ⅲ类标准。生物反应池配置鼓风曝气和富氧曝气，两套曝气设备相互联动调整，实现精准供氧。通过设计优化，制氧机配置由3台（170 m3/h）调整为近期2台（80 m3/h）加1台（160 m3/h），远期3台（160 m3/h）；鼓风机细化选型后实现了运行工况范围内风量的连续衔接，说明了预估计算的必要性。
Abstract:
With the gradual improvement of water purification plant diacharge standards, there is a growing demand for stability, low carbon emissions, and energy efficiency in the construction and operation of such facilities. Accurate oxygen supply has become a standard feature in the construction of water purification plants. In order to fully utilize its function, it is essential to assess the changes in water quantity and quality of water purification plants, and implement appropriate oxygen supply equipment configurations. A water purification plant is designed with an underground layout, and the primary effluent indexes need to comply with the quasi-Ⅲ class limits specified in Environmental Quality Standards for Surface Water (GB 3838-2002). The biological reaction tank is equipped with blast aeration and oxygen-enriched aeration. The two sets of aeration equipment were adjusted in tandem to achieve accurate oxygen supply. Through optimization, the configuration of the oxygen generator was adjusted from 3 sets with aeration intensity of 170 m3/h to 2 sets with aeration intensity of 80 m3/h plus 1 set with aeration intensity of 160 m3/h in the near future, and eventually to 3 sets with aeration intensity of 160 m3/h in future. After carefully selecting the blower, it was essential to establish a continuous connection of the air volume within the range of operating conditions. It highlighted the importance of pre-estimation in ensuring smooth and efficient operation.
