More Information
Summary:The invention provides an anaerobic sludge flotation removing circulation wastewater treatment system and method. The method includes the steps: wastewater is guided to pass through a wastewater treatment tank, so as to carry out wastewater treatment; in the wastewater treatment tank, the wastewater is subjected to an anaerobic treatment reaction with an anaerobic wastewater treatment device; in the wastewater treatment tank, biogas produced from the anaerobic treatment reaction is collected; a part or all of the biogas is recycled and circularly transported to a biogas flotation removing device; and in the wastewater treatment tank, the wastewater is subjected to flotation removing operation by using the biogas of the biogas flotation removing device, so as to recycle suspended small anaerobic sludge and produce flotation-removed anaerobic sludge. The system overall structure can be simplified, and the efficiency of anaerobic wastewater treatment is improved.
