抗生素废水处理工程优化设计及快速启动

OPTIMIZATION DESIGN AND QUICK START-UP OF AN EXTENDING PROJECT FOR ANTIBIOTIC WASTEWATER TREATMENT

扩建工程调节池前置保证了隔油池的处理效果,减少了一级提升,并保证了初沉池负荷的稳定性。地面加热与储热节省了工程投资,降低了噪音,并有利于废水温度的稳定。好氧污泥在厌氧沉淀池沉淀后,降低了污泥含水率,减少污泥总量。扩建工程UBF反应器接种50m3同种废水厌氧颗粒污泥,经35d完成反应器的启动。启动结束时负荷达4.1kgCOD/m3.d,系统运行稳定,COD平均去除率为90%。

In the design of the extending project, the regulating tank was proposed to ensure the treating effect ofoil isolated tank and the stability of primary sedimentation tank＇s load, and save the rising of water level. The heating on ground and thermal storage adopted economized the investment of the project, lowered noise and were advantageous to stability of wastewater temperature. After aerobic sludge sedimented in anaerobic sedimentation tank, water content in sludge lowered and total sludge quantity was decreased. The UBF reactor of the extending project was inoculated with anaerobic granular sludge of the same kind of 50m^3 wastewater, 35 days later, the start-up of the reactor completed. When start-up ended, the load reached to 4.1kg- COD/m^3·d, the system operated stably and average COD removal rate was 90%.
