Multi-module integrated equipment and method for rapidly treating oily sludge

Abstract

The invention discloses multi-module integrated equipment and method for rapidly treating oily sludge. The integrated equipment comprises an earthworm plant filter tank, a thermal cleaning chamber, a precipitation device and an oil-water separator. The thermal cleaning chamber assists in treating sludge through microwaves. A cleaning agent, a demulsifying agent and a flocculating agent which are subjected to ultrasonic treatment are added in the sludge cleaning and precipitation process. The precipitation device realizes separation of sludge and an oil-water mixture. The precipitation device is connected with the oil-water separator through a water outlet pipe. The oil-water separator is connected with the earthworm plant filter tank through a sewage conveying pipe. The precipitation device is connected with the earthworm plant filter tank through a sludge pumping pipe. Sewage can be directly discharged or reutilized after being treated by the earthworm plant filter tank. Sludge is treated by wormcast in the earthworm plant filter tank to form earthworm cast fertilizer, and agricultural utilization is realized. Oily sludge can be continuously treated by the wormcast, and continuous treatment of the oily sludge is realized. A large number of chemical reagents are not used in the treatment process, and pollution is avoided. The operation cost is low, and the degradation efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of sludge resource treatment, and in particular relates to an integrated equipment and method for rapidly treating oily sludge with multiple modules. Background technique [0002] With the continuous development of social economy, the demand for petroleum products continues to increase, the process of petroleum development is further deepened, and the mining technology continues to improve, resulting in a large amount of oily sludge produced in the production activities of the petrochemical industry and related industries. The oily sludge is huge, if it is discharged directly without treatment, it will not only occupy a large amount of land, but also cause serious pollution to the surrounding soil, water, and air, accompanied by the generation of foul-smelling gases. Moreover, the sludge contains a large amount of pathogenic bacteria, parasites (eggs), copper, zinc, chromium, mercury and other heavy metals, ...

AI Technical Summary

Problems solved by technology

[0005] 1. The internal component structure of oily sludge is complex, and there are too many factors affecting the treatment process. The treatment process of ordinary sludge cannot meet the discharge standards;

[0006] 2. High energy consumption and operating costs;

[0007] 3. Special processing equipment is required, and the equipment cost is high;

[0008] 4. The degradation efficiency is low, the related reactor conditions are not easy to control, and the cycle is long;

[0009] 5. Need to use a large amount of chemical reagents, which is not good for subsequent processing
