Study of Device via Combined Filler for Ship Sewage Treatment

Based on the development of elastic flexible filler, a new device for ship sewage treatment which utilizes the new elastic flexible filler was designed. The Main factors influencing the disposal efficiency of the device were researched and analyzed, using an Simulative ship sewage as raw wastewater. The experimental results reflected that the biofilm grew faster under the condition that the surface area of the elastic flexible filler was larger. The relationships among the microorganism growth period, characteristics of elastic flexible filler, biofilm thickness and characteristics of ship sewage were presented. Other factors which influenced the disposal effect were also discussed. The results showed that the device had excellent performance because of effective elastic flexible filler and integrative design.
