发明名称	Secondary sewage treatment system
摘要	A secondary sewage treatment system is provided with a treatment vessel (7) disposed within a septic tank. The treatment vessel has a draft tube (9) for aerating and circulating waste liquor through the treatment vessel and through media contained within the treatment vessel. The media has one part (20) that is submerged media and another part (22) that is an unsubmerged trickle media. The operation of the draft tube circulates waste liquor within the treatment vessel through the submerged media and up through the draft tube where it is expelled and trickles down through the trickle media back into the liquor in the lower portion of the treatment vessel.
