Embodiment 1

[0021] Embodiment 1: Taking the method of preparing a novel oil production wastewater adsorbent by using oil sludge pyrolysis residue at one time as an example, the present invention will be further described in detail.

[0022] A method for preparing a novel oil recovery wastewater adsorbent by using oil sludge pyrolysis residues, including grinding and screening oil sludge pyrolysis residues, acid impregnation treatment, rinsing to neutrality, mixing with polytetrafluoroethylene (binder), cold pressing, and carbonization The specific process of carbonization, rinsing and drying in the furnace is as follows:

[0023] Step 1: Grinding and screening the sludge pyrolysis residue. The material used is the residue after high temperature pyrolysis of oily sludge composed of mineral oil, minerals and water produced in the original crude oil exploitation, gathering and refining process. The sludge pyrolysis residue particles are ball milled and passed through a 100-mesh screen to ob...

Abstract

The invention discloses a method of preparing an oil-extraction wastewater adsorbent by using pyrolysis residues of oil sludge for applying in sewage treatment of oil field, comprising the following steps: grinding and sieving the pyrolysis residues of oil sludge, carrying out acid dipping process, rinsing to neutral, mixing the pyrolysis residues of oil sludge with Teflon (binder), carrying out cold press for moulding, charring in a carbonization furnace, rinsing and drying. The method improves the adsorptivity of the pyrolysis residues of oil sludge and is applied successfully in the treatment of oil-extraction wastewater.

Description

technical field [0001] The invention relates to the technical field of oil field sewage treatment. In particular, it relates to a method for preparing a novel oil production wastewater adsorbent by using oil sludge pyrolysis residue. Background technique [0002] Oily sludge is a kind of muddy substance composed of mineral oil, minerals and water produced in the process of crude oil extraction, gathering, transportation and refining. It has the characteristics of complex composition, large changes in properties and serious environmental hazards. According to incomplete statistics, the amount of oily sludge produced in China is increasing year by year, reaching 10×10 in 2006. 5 t~44×10 5 t, there is still a large amount of oil sludge to be treated. The current treatment methods are mainly simple landfill and simple incineration, which cause serious environmental pollution and waste of resources. Pyrolysis technology has the advantages of thorough treatment, good volume an...
