PURPOSE: A recycling type livestock wastewater treating system is provided to reuse filtered sludge as compost and to burn a float material to emit clean air into the atmosphere. CONSTITUTION: A recycling type livestock wastewater treating system comprises a wastewater treating apparatus(200) which treats waste water generated in a resource-obtaining apparatus and method. The resource-obtaining apparatus comprises a selector, acid fermenter, pH controller, and anaerobe fermenter and generates biogas. The biogas includes a desulfurizer, gas preservation apparatus, and a gas purifier. The waste water-treating apparatus comprises a pre-treating apparatus, a main-treating apparatus, and a final treating apparatus.
