琅东污水厂二期氧化沟推流器的优化改造与运行实践

Koh larn east second phase oxidation ditch sewage factory push flow,the optimization of the transformation and operation practice

针对南宁市琅东污水厂二期氧化沟氧利用效率低,推流器设备损坏率高等现象,导致氧化沟的非正常运行,出水水质变差等问题,2010年对氧化沟改造、原氧化沟的推流器进行了更换和维修。通过实施技术改造后,氧化沟的氧气利用效率得以提高,出水水质明显改善,同时也降低推流器能耗,节约运行成本。

In view of the east secondary oxidation ditch sewage plant of Nanning post oxygen utilization efficiency is low,pushing the inverter equipment damage rate higher phenomenon,lead to oxidation ditch abnormal operation,the issue such as difference of water quality change,the reconstruction of the oxidation ditch and the inverter of the former oxidation ditch have been replaced and maintained in 2010. Through technical reform,oxygen utilization efficiency is improved oxidation ditch,water quality improved significantly,but also reduce energy consumption of pushing the inverter,save operating cost.
