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。
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 nearly900 000 yuan.
