A LIVESTOCK WASTEWATER TREATMENT SYSTEM USING CONSTRUCTED WETLANDS

摘要

PURPOSE: An environmental friendly treatment system of livestock wastewater in constructed wetlands remarkably improves the efficiency of livestock wastewater treatment through a first and a second purification. CONSTITUTION: An environmental friendly treatment system of livestock wastewater in constructed wetlands includes a livestock wastewater collection bath (1), multiple filter tubs (5), a bioreactor (10) and a water processor. The bioreactor accepts livestock wastewater ejected from the multiple filter tubs to firstly purify the livestock wastewater. The water processor accepts the first purified livestock wastewater to secondly purify and discharge the first purified livestock wastewater under either the aerobic condition or the anaerobic condition. The water processor comprises a vertical flow tub (30) and a horizontal flow tub (20). The vertical flow tub accepts the livestock wastewater passed through the bioreactor to purify the livestock wastewater under the aerobic state and discharge the waste water. The horizontal flow tub accepts the livestock wastewater passed through the vertical flow tub to purify the livestock wastewater under the aerobic state and discharge the waste water.
