Abstract

The invention discloses a method for treating oily sludge, including a restoration agent, equipment and a method for using the equipment. The restoration agent includes quicklime, calcium oxide, magnesium oxide, volcanic ash and graphene. The use equipment consists of the first It consists of a mixing system, a mechanical dehydration system, an oily sewage treatment system, a second mixing system, a solid-liquid separation system, a drying device, a gas treatment system, a brick making system and a granulation system. Low consumption, low cost, no secondary pollution. Through a variety of processes, the waste water, waste residue and waste gas generated during the treatment of oily sludge can be completely eliminated. At the same time, the heat, waste residue and purified water generated in the process can be recycled in the system, which greatly reduces oily pollution. The cost of sludge treatment, the discharge of treated wastewater, waste residue and waste gas can all meet the requirements of the national environmental protection, and realize the harmless treatment of oily sludge.

Description

technical field [0001] The invention belongs to the technical field of oily sludge treatment, and in particular relates to a method for oily sludge treatment. Background technique [0002] In recent years, the world's demand for oil and minerals has also been increasing, which will produce a large amount of oil pollutants in the process of mining, refining and transportation, including complex components, large output, and serious hazards. Solid Waste - Oily sludge, also known as a "by-product" of petroleum production. At present, during the crude oil dehydration process, a large amount of oily sludge will be generated at the bottom of the dehydration tank, oil storage tank, etc. At the same time, there is also a large amount of oily sludge in the sewage treatment plants of oil fields and refineries (such as the bottom of grease traps, flotation tanks, aeration tanks, etc.). Processing 20000m a day 3 The sewage treatment plant produces about 20m per day 3 Oily sludge. ...
