  • 摘要: 近年来,微滤-反渗透(MF-RO)工艺在污水再生处理领域中的应用越来越受到关注,但其设备投资和运行成本较高,需要建立科学、高效的运行管理机制和投入产出机制,以提高其经济效益。系统研究了北京市某再生水厂微滤-反渗透(MF-RO)工艺的设备投资及运行费用等情况。再生水成本主要由设备折旧费和运行成本组成,其中运行成本所占比例较高,而在运行成本中所占比例最高的是膜更换费、电费和药剂费。目前该厂再生水销水量约为7 000 m3/d,运行负荷率仅为33.33%,导致再生水成本较高,总成本约达5.29元/m3,其中设备折旧费为0.83元/m3,运行成本约为4.46元/m3。因此提高运行负荷率,即提高销水量,是降低再生水成本的关键。
    Abstract: Recently, microfiltration/ultra-filtration combined with reverse osmosis (MF/UF-RO) are widely used in wastewater reclamation. Because of high investment and operation costs of MF/UF-RO process, optimal operation and management and input-output mechanism should be established to improve its economic benefits. The investment and operation cost of a MF-RO process in a wastewater reclamation plant in Beijing was evaluated in this paper. The total production cost consists of equipment depreciation cost and operation cost. The operation cost constitutes the greatest part of the total production cost, while membrane replacement cost, electricity cost and chemical cost are the major parts of the operation cost. The production amount of reclaimed water is about 7 000 m3/d these days. The low operating load rate (33.33%) leads to high production cost. The equipment depreciation cost and operation cost are about 0.83 and 4.46 yuan per ton permeate, respectively. The total production cost is about 5.29 yuan per ton permeate. Increasing the treatment amount of and the load rate is the key to decrease the total production cost.
