Method for preparing ceramsite filter material by using oily sludge |
| abstract |
A method for preparing ceramsite filter material by using oily sludge belongs to the technical field of harmless treatment of wastes in crude oil exploitation. Steps: respectively weigh the hematite powder and sludge according to the mass ratio, mix and stir evenly to obtain the iron-carrying sludge; introduce the iron-carrying sludge into the plasma reaction tank and continuously expose it to air from the bottom of the plasma reaction tank to dispel the plasma. The iron-loaded sludge in the reaction tank is irradiated with low-temperature plasma to obtain devolatile active iron-loaded sludge; the calcium oxide powder and the perlite powder are respectively weighed according to the mass ratio, mixed and stirred evenly to obtain the calcium-doped perlite powder; The calcium-doped perlite powder and the devolatile active iron-carrying sludge are respectively weighed, mixed and stirred evenly to make ceramsite, which are then dried and sintered at high temperature in turn, and then slowly cooled to obtain ceramsite filter material. The oil quality and mud quality in the oil sludge can be fully utilized; the preparation process steps are short, cheap and easy to obtain; and the soil and water system are prevented from being damaged by the high oily sludge. |
