The invention discloses a method and a system for plasma processing of oily sludge. The method comprises the following steps: 1) conveying the oily sludge into a plasma furnace for treatment to decompose decomposable materials and obtain sludge residues, and cooling the sludge residues; 2) grinding the sludge residues to a predetermined particle size by a grinding machine; 3) mixing the ground waste materials, oxide powder and a sustained release agent by a stirrer to form a mixture; 4) feeding the mixture and a phosphate-containing solution into a reactor for reacting to generate a phosphateslurry of the oxide; and 5) delivering the stirred slurry into a molding machine for forming a predetermined shape and curing to form phosphate ceramic. The method and the system provided by the invention convert the decomposable substances in the oily sludge into a synthetic gas, physically and chemically encapsulate the sludge residues with phosphate to generate the phosphate ceramic, and stabilize heavy metals contained in the oily sludge, so as to advantageously protect the environment.
Description
technical field [0001] The invention relates to an oil sludge plasma treatment system and method, belonging to the technical field of waste treatment. Background technique [0002] Oilfield exploitation adopts the method of water injection to maintain formation pressure. With the deep exploitation of oil fields, the muddy water content in the produced crude oil is getting higher and higher, and a large amount of oily mud sand will be produced in the crude oil dehydration treatment process in the combined station. [0003] Oily wastewater from oil fields contains small solid particles that are difficult to settle naturally. These solid particles have a small particle size and form a stable emulsion system with water and oil. A coagulant must be added to make them aggregate into agglomerates and then settle to achieve Requirements for water quality after sewage treatment. Although this reduces the solid matter content in the sewage, a large amount of oily sludge is produced ...
