种污泥重金属生化处理方法，包括以下步骤：将待处理的污泥通过第通气口向第罐体内曝气，气流由第引流罩的第下开口向第引流罩内流动，在第引流罩内形成不规则的涡流和负压，污泥、氧化硫杆菌及培养液从引流罩的底部被吸入、提升到第引流罩内充分混合，并在气流的作用下由第引流罩的第上开口流出并沉降回流到第罐体内，回流到第罐体内的污泥、氧化硫杆菌及培养液再次受气流作用从第引流罩的底部被吸入、提升到第引流罩内，从而在第罐体和第引流罩之间反复循环，使得污泥的重金属和氧化硫杆菌获得充分的气固接触效果，使得重金属受氧化硫杆菌的氧化和酸化作用从污泥中溶出，消除污泥内重金属的含量。 A biochemical treatment method for heavy metal in sludge comprises the following steps that the sludge to be treated is aerated into a first tank through a first vent hole, airflow flows into a first flow guide cover from a first lower opening of the first flow guide cover, and irregular vortexes and negative pressure are formed in the first flow guide cover; the sludge, sulfur oxide bacillus and culture liquid are sucked into the flow guide cover from the bottom of the flow guide cover and lifted into the first flow guide cover to be fully mixed, flow out of a first upper opening of the first flow guide cover under the action of the airflow and are settled to flow back into the first tank; the sludge, sulfur oxide bacillus and culture
