浙江某印染废水处理工程改造及分析
- Title:
- Reconstruction and Analysis of a Printing and Dyeing Wastewater Treatment Project in Zhejiang
- 摘要:
- 介绍了浙江某印染厂废水处理工程改造的工艺流程、技术参数、运行成本及实施效果。改造工程主要采用物化+推流式生化系统+砂滤+反渗透处理工艺,在系统平均进水COD、色度、电导率分别为2 300 mg/L、337倍、3 335 μS/cm的情况下,系统平均产水COD、色度、电导率分别为16.75 mg/L、6.25倍、116.75 μS/cm,满足印染工艺回用标准,回用率达到60%。该工艺处理成本(电费+人工费+药剂费+污泥处置费+设备维护费)为2.552元/m3,具有处理技术可靠、运行稳定、易于维护等特点。
- Abstract:
- The technological process, parameters, operation cost and effect of a printing and dyeing wastewater treatment project in Zhejiang were introduced. The combined process of physio-chemistry, plug flow biochemical system, sand filtration, and reverse osmosis (RO) was used in the reconstruction project. The average effluent concentrations of COD, chroma and electrical conductivity were 16.75 mg/L, 6.25 times, 116.75 μS/cm respectively, with average influent concentrations of 2 300 mg/L, 337 times, 3 335 μS/cm respectively, which could meet the reuse standard of dyeing and printing process. The recycling rate of wastewater reached over 60% and the treatment cost including electricity, labor, chemicals, sludge disposal and equipment maintenance cost was about 2.552 yuan/m3. It had the characteristics of reliable processing technology, stable operation, easy maintenance and etc., which showed good practical application value.
