Keywords: Swine wastewater, aeration, microorganism treatment, bio-filter
A new swine wastewater treatment system is demonstrated and compared with current technologies. Comparisons include solid-liquid separation, sedimentation, aeration of wastewater, bio-filter pond and microorganism treatment. This new treatment technology can comprehensively utilize swine wastewater while meeting discharge standard through solid-liquid separation, acidification and high efficient bio-filter, bio-oxidation pond. Application of the new treatment system in a piggery demonstrated a bio-filter and the total COD removal rates of the system were 93%`97%, respectively. Therefore, the new system combines a single treatment process into a comprehensive treatment system that may have considerable economic, social and ecological benefits.(Download PDF) (Export to EndNotes)
