Study on Sludge Treatment Method and Development Direction

Abstract

A large amount of oily sludge is produced in the oilfield production process. The harmful substances contained in sludge can cause great harm to the atmosphere, soil, water and human body. With the deepening of people's understanding of the hazards of sludge, the environmental law in our country is further perfected and perfected. The treatment of sludge has become an urgent problem to be solved. Now commonly used sludge treatment technology is mainly solvent extraction technology, curing technology, hot water washing technology, but these technologies have some limitations, such as high energy consumption, secondary pollution, long treatment cycle. The complexity of the sludge component determines that the single treatment method cannot realize the harmless reduction, reduction and resource recovery of the sludge treatment. The integrated sludge treatment method will be the development direction of the future sludge treatment technology.
