A complete three-slime recovery and treatment process

Abstract

The invention provides a set of three-sludge recycling treatment technology which comprises the following steps: adding three sludge and a flocculating agent into a centrifuge for centrifugation; conveying the obtained dry sludge into a thick sludge pump, and conveying the obtained sewage into a sewage treatment plant for recycling treatment; injecting a water flow into the thick sludge pump so as to convert the dry sludge into three sludge with the water content of 93-94%; conveying the three sludge with the water content of 93-94% into a sludge mixing tank, and then conveying the three sludge into a sludge circulating pump from the sludge mixing tank; outputting the uniformly stirred three sludge by the sludge circulating pump; conveying the uniformly stirred three sludge and water vapor together into a three-sludge dispersion device so as to tear and disperse the uniformly stirred three sludge into tiny droplets; and conveying the tiny droplets as a large vapor blowing medium into a joint coking device to finish a coking process. The technology provided by the invention has the following beneficial effects: tiny droplets are obtained through centrifugation, stirring and dispersion, and the droplets can serve as a large vapor blowing medium and enter the joint coking device for recycling; and through the design, all three sludge can be recycled at low cost, and the aims of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a complete three-sludge recovery and treatment process. Background technique [0002] At present, during the production and processing of petroleum, there will be three kinds of mud composed of scum, biochemical sludge and bottom mud of grease trap. The water content of the three muds is generally 98%. If the staff does not deal with the above-mentioned three muds accordingly, the places where the three muds go will cause serious pollution and damage to the ecological environment. The traditional treatment method can only realize the recycling of part of the waste, and a large part of the waste needs to spend a lot of money to entrust the corresponding hazardous waste treatment center for recycling. This not only causes the utilization rate of the three muds to be too low, but also increases the processing cost of the three muds to a large extent. [0003] It can be s...

If the staff does not deal with the above-mentioned three muds accordingly, the places where the three muds go will cause serious pollution and damage to the ecological environment

The traditional treatment process can only realize the recycling of part of the waste, and a large part of the waste needs to spend a lot of money to entrust the corresponding waste treatment center to recycle.

This not only causes the utilization rate of the three muds to be too low, but also increases the processing cost of the three muds to a large extent
