Abstract
본 발명은 폐수를 활성오니 처리할 때 발생하는 벌킹을 억제하는 방법에 관한 것으로, 유기물을 함유한 폐수를 활성오니법으로 처리할 때 폭기조내에 포화탄화수소 염화물, 불포화탄화수소 염화물 또는 염화알데히드의 1종 또는 2종 이상을 200ppm 이하되도록 첨가하여 유기물 함유 폐수의 활성오니 처리시 사상균을 억제함으로 벌킹현상을 방지하여 오니의 침강성 및 분리성을 좋게하여, 폐수처리 효율을 증대시키기 위한 활성오니 처리시 벌킹억제방법.The present invention relates to a method of suppressing bulking generated when treating wastewater with activated sludge, wherein when treating wastewater containing organic matter with activated sludge method, one or more of a saturated hydrocarbon chloride, unsaturated hydrocarbon chloride, or aldehyde chloride is used in the aeration tank. By adding two or more kinds to be 200ppm or less to prevent filamentous bacteria during the treatment of activated sludge in the wastewater containing organic matter, preventing bulking phenomenon, improving sedimentation and separability of the sludge, and improving the wastewater treatment efficiency. .
