Abstract

The efficiency of individual units of an effluent treatment plant (ETP) determines the overall performance of the plant and the final effluent quality.  In this study an ETP of a composite textile industry was investigated using this method.  Water samples were collected from the main units of the ETP and were analyzed for key parameters.  The results were used to diagnose problems with the treatment units and to suggest modifications.  From this, a simple but robust methodology was developed for evaluating the performance of the different treatment units and the ETP as a whole that could be implemented by ETP managers on a regular basis to improve the performance so that the effluent leaving the factory meets national standards and conforms to the requirements of international buyers.  The results showed that poor management, especially chemical dosing, was seriously affecting the ETP's performance and that simple measures could address the problems.

孟加拉国纺织废水处理厂性能分析方法
污水处理厂(ETP)各个单元的效率决定了工厂的整体性能和最终的出水质量。本文采用该方法对某复合纺织工业的ETP进行了研究。从ETP的主要单元采集水样,并对关键参数进行分析。结果用于诊断治疗单位的问题,并提出修改建议。由此,开发了一种简单而有力的方法,用于评估不同处理单元和ETP作为一个整体的性能,ETP管理人员可以定期实施该方法,以改善性能,使工厂流出的污水符合国家标准并符合国际买家的要求。结果表明,管理不善,特别是化学药品的添加,严重影响了ETP的性能,简单的措施可以解决这些问题。DOI: 10.3329/cerb.v13i2.3939化工研究通报13 (2009)61-66
