Abstract

The invention relates to a process for treating petrochemical wastewater. The process comprises a plurality of working procedures and implementation steps such as oil removal by a sloping plate, advection oil separation, pressure floatation, primary floatation by a gas-liquid reaction, biotreatment, secondary floatation, neutralization and filtration and scum and sludge treatment. The process has simple equipment technology, easy implementation and low operating expense; and the process is utilized to rapidly treat wastewater produced in the process of petroleum processing with high efficiency and recycle oil products, thereby effectively reducing environmental pollution and achieving good economical and social benefits.

Description

Technical field: [0001] The invention relates to a technology for sewage treatment in petroleum processing. Background technique: [0002] Petrochemical wastewater is the sewage generated in the crude oil processing process, which is a kind of oily wastewater. Gases, organic matter, etc., when the crude oil is dehydrated, a large amount of chemicals must be added. Because petrochemical wastewater generally contains a certain amount of chemical agents such as crude oil, inorganic ions, sulfides, organic phenols, cyanide, bacteria, solid particles, and catalysts added during processing, the treatment process is complicated, and there are many types of pollutants. Therefore, it is necessary to effectively treat petrochemical wastewater. At present, there are various oily sewage treatment methods and technologies used on site. The common goal is to remove a large amount of oil in the water, and at the same time remove dissolved organic matter, suspended solids, soaps, acids an...
