摘要
通过对湘潭纺织厂废水处理工艺存在的问题进行研究和分析 ,对其废水处理工艺进行了改进。采用“二级生物接触氧化 砂滤 活性生物炭”工艺后 ,废水经其处理 ,水质各项指标超过国家一级排放标准 ,水质可以完全回收利用 ,废水处理成本下降 1 3左右。
The wastewater treatment process of Xiangtan Textile Factory has been improved by studying and analyzing the existing problems of the wastewater treatment process of the factory.After the new process of two stage biological contact oxidation sand filtering active biological carbon was adopted,every index of water exceeded primary discharging standard of China,the water could be reused and the cost of wastewater treatment was decreased by 1/3 or so when the wastewater was treated by the new process.
