Experimental study on in-situ rainwater quality improvement technology of intermittent aeration coupled with polyurethane biological sponge filler

间歇曝气耦合聚氨酯生物海绵填料、间歇曝气和自然沉淀的原位雨水水质改良技术对氨氮、亚硝酸盐氮、硝态氮和总氮浓度的变化在不同曝气速率 （1.0 L/min、2.0 L/min、4.0 L/min） 下。

This dataset investigates the effects of an in-situ rainwater quality improvement technology (which couples intermittent aeration with polyurethane biological sponge filler, and combines intermittent aeration and natural sedimentation) on the variations in concentrations of ammonia nitrogen, nitrite nitrogen, nitrate nitrogen and total nitrogen under three different aeration rates: 1.0 L/min, 2.0 L/min and 4.0 L/min.
