Non-Woven Fabric Media for Wastewater Treatment and Mechanism
无纺布填料处理污水试验及机理

Non-woven fabric was adopted as a new kind of suspended media. Adapting condition and operation parameters and biodegradation mechanism using non-woven fabric media in wastewater treatment were studied. The result of experiment shows that different CODCr volumetric load should take different media volume. When CODCr volume load was lower than 1.2 kg/(m3.d), the volume ratio of media to reactor should be 20%; the CODCr volume load between 1.2-2.0 kg/(m3.d), the volume radio of media to reactor 38%; the CODCr volume load was larger 2.0 kg/(m3.d), the volume radio of media to reactor 29%. The result of the model shows that the biodegradation rule of pollutant can be described by the format of Monod Equation.
