Problems solved by technology

[0003] At present, the high content of COD, SS, petroleum and total phosphorus leads to the difficulty of running the biochemical load in the later stage. The existing sewage treatment chemicals (polyaluminum chloride, polyferric sulfate, aluminum sulfate) and other products have poor treatment effects

Abstract

The invention discloses a preparation method of an oily sewage treatment agent for petrochemical industry, and belongs to the technical field of sewage treatment. The preparation method comprises the following steps: 1), taking 1 part of montmorillonite, 1 part of water and 1 part of sulfuric acid; 2) mixing and activating the raw materials in the step 1), and performing plate-frame press filtration to obtain a montmorillonite stock solution; and 3) adding anhydrous aluminum hydroxide, a catalyst and sulfuric acid into the montmorillonite stock solution, and activating; and after the activation process in the step 3) is carried out for 1 hour and the content of aluminum oxide is qualified, continuously activating for 1 hour to obtain a finished product solution. According to the invention, with the agent containing the aluminum hydroxide, the sulfuric acid, the catalyst and the montmorillonite stock solution, the difficult problem that COD, SS, petroleum and total phosphorus are difficult to degrade is solved, the wastewater treatment process of the whole petrochemical industry is further improved, the problem of poor treatment effect of an existing sewage treatment agent (aluminum polychlorid, polyferric sulfate, aluminum sulfate) and other products is solved, and the problem of difficult load operation of later biochemical treatment is solved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a preparation method of an agent for treating oily sewage in petrochemical industry. Background technique [0002] Petrochemical wastewater is generally discharged from petrochemical plants. The organic matter contained in petrochemical wastewater is mainly hydrocarbons and their derivatives, the organic pollution is serious, the chemical oxygen demand (COD), solid suspended solids (SS), petroleum and total phosphorus are high, and many reactions in petrochemical production are It is completed under the action of a catalyst, and the wastewater often contains heavy metals. [0003] At present, the high content of COD, SS, petroleum and total phosphorus leads to the difficulty of running the biochemical load in the later stage. The existing sewage treatment chemicals (polyaluminum chloride, polyferric sulfate, aluminum sulfate) and other products have poor tre...
