摘　　要：丝状菌污泥膨胀会导致污泥絮体结构松散,难以沉降分离,影响出水水质,从而造成活性污泥法净化污水效果较差。为此,针对当前药剂法、环境调控控制法和代谢机制控制法等多种方法无法应对多种污水水质情况,使得污泥膨胀控制程度不足,无法达到规定的标准,研究一种新的考虑污水水质的丝状菌污泥膨胀控制方法。该方法将药剂法与代谢机制控制法相结合,通过二者取长补短,充分发挥各自优势,增强丝状菌污泥膨胀控制力度。The bulking of filamentous sludge will lead to the loose structure of sludge flocs,which is difficult to settle and separate,and will affect the quality of effluent water,thus the effect of activated sludge process on sewage purification is poor.Therefore,in view of the current pharmaceutical method,environmental regulation and control method,metabolic mechanism control method and other methods can not cope with a variety of sewage quality,which makes the sludge expansion control degree insufficient and can not meet the specified standards,a new method of filamentous bacteria sludge expansion control considering sewage quality is studied.This method combines the medicament method and the metabolic mechanism control method,through their advantages and disadvantages,give full play to their advantages,and enhance the control of filamentous sludge bulking.
