SOLID-LIQUID SEPARATING TYPE LIVESTOCK WASTEWATER TREATMENT APPARATUS

摘要

PURPOSE: A solid-liquid separating type livestock wastewater treating apparatus is provided to prevent the pollution of rivers by separating livestock wastewater and sterilizing separated urine effluent before discharging. CONSTITUTION: A solid-liquid separating type livestock wastewater treating apparatus includes a notch type mixing tank(2), a mixed water discharging pipe(71), a solid-liquid separator(4), a solid part collecting bath(5), a primary oxidizing bath(6a), a secondary oxidizing bath(6b), a microorganism filtering bath(6c), and a sterilizing bath(7). An underwater pump is installed in a livestock wastewater collecting tank. Wastewater pumped by the underwater pump and water mixed with a coagulating agent in a coagulating agent mixing tank are simultaneously introduced into the notch type mixing tank. The mixed water discharging pipe discharges the mixed water of the wastewater and the water with the coagulating agent. The solid-liquid separator separates the mixed water into solid parts and urine effluent. The primary oxidizing bath oxidizes the urine effluent. The secondary oxidizing bath stores the primarily oxidized urine effluent to be secondarily oxidized. The microorganism filtering bath filters microorganisms from the secondarily oxidized effluent.
