Abstract

The invention discloses a sulfonation waste mud treatment process. The process includes steps: after fluidization reaction of sulfonation mud, removing fine sand from sulfonation mud; performing homogenization reaction in a first homogenization tank; performing solid-liquid separation; subjecting a solid phase obtained in separation to secondary homogenization reaction in a second homogenization tank, and allowing a liquid phase obtained by filter pressing to enter a temporary storage device; subjecting the liquid phase in the temporary storage device to air flotation treatment in a micro-nanoair flotation treatment; after electrochemical reaction of the liquid phase in a high-voltage pulse electrocoagulation treatment unit, subjecting the liquid phase to double-layer filtration in a double-film filter device, enabling part of clean water obtained after filtration to enter a preparation tank to realize agent preparation, and enabling a small quantity of concentrated water to enter anMVR evaporation device to realize evaporative crystallization. The novel process is provided for sulfonation mud treatment, technical simplicity, energy saving and high treatment efficiency are realized, and treated sulfonation mud reaches discharge standards.

Description

technical field [0001] The invention relates to the technical field of oilfield mud treatment, in particular to a sulfonated waste mud treatment process. Background technique [0002] The three-sulfur mud system is also called the sulfonated mud system. It is a high-temperature-resistant mud system with excellent performance and low price commonly used in domestic oil fields. It is mainly used in the deep well drilling process when the drilling depth reaches 2000-3000m. It is widely used in various oil fields. The three-sulfur mud system is a mud system formed by adding sulfonated phenolic resin, sulfonated lignite, sulfonated tannin and other substances to the mud system. [0003] The drilling waste fluid produced during the use of the sulfonated mud system becomes the sulfonated waste mud. The main characteristics of the sulfonated waste mud are high water-soluble COD value and large chroma; the sulfonated waste mud also contains a large amount of inorganic salts, High-mo...
