Domestic and Livestock Wastewater Treatment Apparatus and Method Using a Single Reactor

摘要

The present invention relates to a wastewater treatment apparatus and a treatment method consisting of a single reaction tank, by installing a hopper-type sedimentation tank with an open bottom in the aeration tank so that the sediment sludge in the sedimentation tank flows into the aeration tank by gravity, and the aeration tank mixed liquid in the sedimentation tank By intermittently spraying through a plurality of nozzles protruding from the lower edge and the center of the mounted washing column, all sludge deposited in the hopper of the sedimentation tank is returned to the aeration tank, and the sludge deposited at the bottom of the aeration tank at the bottom of the sedimentation tank is disturbed. By mixing with the mixed liquid in the aeration tank, sludge is prevented from rising into the sedimentation tank, which enables effective separation of the treated water and sludge from the sedimentation tank, and maximizes the purification effect by the microorganisms in the aeration tank and prevents anaerobic decomposition. Configured wastewater treatment device and treatment method It is about.
