Feasibility Study of Individual Treatments of Desizing Wastewater

摘要

The common treatment of printing and dyeing wastewater (PDW) is centralized processing the mix-wastewater generated by each printing and dyeing craft. On the basis of present process, this paper studies on individual treatment of desizing wastewater which contains less water and higher concentration of pollutants. Then takes 2000-tons per day PDW treatment plant as a case to estimate the cost of construction and operation. Compared with technical and economic of individual processing desizing wastewater and centralized processing PDW, it can be shown that individual processing desizing wastewater is more economical. The per cubic meter water can save 0.18 Yuan averagely, and the total of LCC will save 1,396,700 Yuan.
