Abstract

he study aimed to characterize paper mill effluents and determine the quality of surface water in the vicinity of the paper mills using a water quality index to understand the pollution level due to the discharge of untreated effluents. Physicochemical parameters and CCME (Canadian Council of Ministers of the Environment) Water Quality Index (WQI) were used to estimate the degree of pollution in the selected paper mills area in Bogura District of Bangladesh. Moreover, a public perception survey was conducted in the study area to illustrate the present scenario regarding paper mill effluent discharge. The analytical results revealed that the concentrations of TSS, EC, COD, BOD5, phenols, K, and NO3 – N were higher than the permissible limit, and the DO level was below the ECR 1997 standard. However, there was no concentrations of heavy metals exceeded the permissible level. The FTIR analysis showed the presence of several toxic pollutants, including lignin, phenol, and halo compound. The CCME WQI showed that sites S-1 and S-2 were ranked as marginal, while site S-3 was ranked as fair. The study observed that the discharge of untreated paper mill effluent has the potential to cause harm to aquatic life and the environment.

造纸废水的表征及其对环境的影响

他的研究旨在描述造纸厂废水的特征，并利用水质指数来确定造纸厂附近地表水的质量，以了解由于排放未经处理的废水而造成的污染程度。采用物理化学参数和CCME(加拿大环境部长理事会)水质指数(WQI)来估计孟加拉国Bogura区选定造纸厂区域的污染程度。此外，我们亦在研究区内进行公众认知调查，以说明造纸厂污水排放的现况。分析结果显示，TSS、EC、COD、BOD5、酚类、K和NO3 - N的浓度均高于允许限值，DO低于ECR 1997标准。然而，没有重金属浓度超过允许的水平。FTIR分析显示木质素、苯酚和光晕化合物等有毒污染物的存在。CCME WQI显示，S-1和S-2站点被评为边缘站点，而S-3站点被评为公平站点。研究发现，未经处理的造纸厂废水的排放有可能对水生生物和环境造成危害。
