The invention provides a preparation method of an oil sludge ceramsite lightweight aggregate. The method comprises: S1, mixing oil sludge and active sludge, adding fly ash during the mixing process, and dividing the obtained mixture into a mud material 1 and a mud material 2 according to a weight ratio of 1: 3; S2, mixing the construction waste and the coal gangue, crushing and grinding until the particle size is 0.2-0.5 mm, then mixing spoil and fly ash into the mixture, uniformly stirring, and drying at 90-100 DEG C; S3, mixing the first dry powder into the mud material 2 to form slurry, and putting the slurry, the second dry powder and the mud material 1 jointly into a turbulent flow stirrer for stirring; S4, introducing the mixture obtained in the step S3 into a disc granulator for granulation, gradually adding third dry powder in the granulation process, and granulating to obtain raw material balls; and S5, heating and roasting the raw material balls, and cooling to room temperature to obtain the oil sludge ceramsite lightweight aggregate. The use amount of the oil sludge is about 20wt%, and a large amount of oil sludge can be consumed and treated, so that harmless treatment of the oil sludge is effectively realized.
本发明提供了一种油泥陶粒轻集料的制备方法，其包括如下步骤：S1、将油泥和活性污泥混合，在混合过程中加入飞灰，将混合所得物按重量比例1：3分为泥料一和泥料二；S2、将建筑垃圾、煤矸石混合后进行破碎磨细至粒径为0.2～0.5mm，然后向其中混入弃土和粉煤灰并搅拌均匀，送入90～100℃进行干燥；S3、将干粉一混入泥料二中，混合形成泥浆，并将泥浆、干粉二以及泥料一共同导入到紊流搅拌机中进行搅拌；S4、将S3中所得导入圆盘造粒机中进行造粒，并在造粒过程中逐渐加入干粉三，经造粒后得生料球；S5、将生料球进行升温焙烧，并冷却至室温即得油泥陶粒轻集料。本发明油泥使用量20wt％左右，能够大量对油泥进行消耗处理，从而有效实现对油泥的无害化处理。
