Abstract

An unpresented approach to ameliorate swine waste contamination

Highlights

  • There are 5,539,130 capita pigs in Taiwan which located in pintung, yulin, chunghwa, tainan, chayi, kaohsiunf townships

  • Anaerobic biological treatment processes dealing with high organic loading piggery wastewater possess low energy consumption, methane resource recovery, high treatment capability, low sludge generation, high toxic substance endurance

  • Recent findings have suggested that ammonia can be directly used as an electron acceptor for denitrification in wastewater treatment; the process is named anaerobic ammonia oxidation (ANAMMOX) and occurs in nature

Summary

Introduction

There are 5,539,130 capita pigs in Taiwan which located in pintung, yulin, chunghwa, tainan, chayi, kaohsiunf townships. Anaerobic biological treatment processes dealing with high organic loading piggery wastewater possess low energy consumption, methane resource recovery, high treatment capability, low sludge generation, high toxic substance endurance. The process of wastewater treatment of the piggery industries has three main stages. They are soil liquid separation, anaerobic digestion and aerobic treatment. Soil liquid separation: The primary function of solid liquid separation is scum generation reducing and treatment capacity levying. The advantages of anaerobic fermentation are low sludge generation, methane resource recovery, high organic loading endurance, great treated water production, save oxygen, killing pathogen and virus. Costs and difficulties in operating the system is the limitations that made the treatment of wastewater from piggery industries in Taiwan not widely available. The agricultural wastewater can be proper management as well as piggery waste phytoremediation will be addressed
