中文摘要:
      植物油厂的废水主要来源于生产废水，其COD浓度高、含磷高，因此处理成本较高。从废水处理成本构成要素出发，分析各项费用降低方法，提出应对措施：源头控制，减少污泥，计量管理，变频调速，调整曝气和气浮，利用在线仪器科学加药，加强设备维保管理。经过半年降本措施的实施，某企业废水处理成本降低10.5%，年节省费用近90万元。
英文摘要:
      The wastewater of a vegetable oil plant is mainly from production wastewater, with high-COD, high-total phosphorus, so the treatment cost is high. According to the cost components of wastewater treatment, the cost reduction methods were analyzed, and the corresponding measures were proposed as follows: source control, sludge reduction, metering management, frequency control, adjustment of aeration and air flotation, scientific dosing with on-line instruments, and strengthening equipment maintenance management. After the implementation of cost reduction measures for half year, the wastewater treatment cost of an enterprise was reduced by 10.5% and the annual cost was nearly 900 000 yuan.
