Abstract

The wastewater quality alterations due to the use of cleaning agents, sanitisers, and disinfectants, in addition to the accompanying use of water during COVID-19 have potential impacts on wastewater treatment operations. How the characteristics of wastewater could be altered by the COVID-19 pandemic was the concern of this investigation. Daily records of the Ardiya catchment in Kuwait City were examined for the period 2015–2020. Perhaps due to the excessive use of water during 2020 (446 compared to the five-year average of 436 l/c.d) and the corresponding wastewater generation increase (253 compared to the five-year average of 239 l/c.d), the effect of chemical usage on the wastewater quality has dampened. Nonetheless, an increase in the frequency of COD/BOD ratio > 3, TP in the range 6.5 to 8.5, TKN in the range 40 to 50 were observed in 2020, which was not observed during 2015–2019. These COVID-19 related alterations are important to take into consideration in wastewater treatment operations to achieve wastewater treatment targets.

COVID-19大流行对科威特生活废水特性的可能影响

由于使用清洁剂、消毒剂和消毒剂，以及新冠肺炎期间伴随的用水，导致的废水质量变化对废水处理操作有潜在影响。新冠肺炎大流行如何改变废水的特性是本次调查关注的问题。2015年至2020年期间，对科威特城Ardiya流域的日常记录进行了检查。也许是由于2020年过度用水（446升，而五年平均值为436升/立方厘米）和相应的废水产生量增加（253升，而六年平均值则为239升/立方英尺），化学品使用对废水质量的影响有所减弱。尽管如此，2020年观察到COD/BOD比值>3、TP在6.5至8.5范围内、TKN在40至50范围内的频率增加，而在2015-2019年期间没有观察到这种情况。这些与新冠肺炎相关的变化对于在废水处理操作中考虑以实现废水处理目标非常重要。
