This paper proposes a novel interval prediction method for effluent water quality indicators (including biochemical oxygen demand (BOD) and ammonia nitrogen (NH3-N)). which are key performance indices in the water quality monitoring and control of a wastewater treatment plant. Firstly. the effluent data regarding BOD/NH3-N and their necessary auxiliary variables are collected. https://homehardware4ues.shop/product-category/door-hardware/
