Problems solved by technology

Sewage has a high oil content, and direct discharge will cause serious pollution to the environment
Injecting downhole damages the formation and wastes crude oil. Such highly oily sewage requires a large amount of water treatment agent, and multi-stage sedimentation requires a large amount of dosing, high processing costs, and difficult recovery of crude oil, resulting in the recovery of water treatment agents. Crude oil contains more than 80% water, causing a serious vicious circle. In order to solve this situation, oil production plants reduce the oil content in the water, and add pre-removal agents to crude oil with high water content. At present, the pre-removal agents are all water-soluble, high-molecular-weight, and non-ionic. Polyether, less effective, high operating costs

Abstract

The invention relates to a sewage purification agent and a preparation method thereof, in particular to a high methoxyl pectin (HM) series oily sewage purification agent and a preparation method thereof. The purification agent comprises the following substrate in percentage by mass: 15 to 35 percent of polyamine, 2.5 to 15 percent of non-ionic polyether phosphate, 30 to 60 percent of solvent, and synergist in an amount which is 20 to 50 percent of the total mass of the purification agent. The preparation method comprises the following steps of: obtaining the non-ionic polyether phosphate by processes of polymerization, post treatment and esterification, obtaining the polyamine by processes of synthesis and post treatment, adding the synergist, and thus obtaining a final product. The product has a good oil separation and water cleaning effect, and has the characteristics of high oil separation speed, low dosing quantity, clean treated sewage, readily available raw materials, low price, good water solubility and strong matching performance.

Description

technical field [0001] The invention relates to a sewage purifying agent and a preparation method thereof, in particular to an HM series oily sewage purifying agent and a preparation method thereof. Background technique [0002] Both water and oil are extremely important substances for human survival. Although my country's total water resources occupy the sixth place in the world. However, the per capita water volume is only a quarter of the world's per capita water volume, ranking 88th in the world. Oil is one of the three major energy sources, which has a direct impact on the development of the national economy and the improvement of people's living standards, so saving water and oil is a major issue for the national economy and the people's livelihood. [0003] Since the reform and opening up, with the development of industry and agriculture and the improvement of people's living standards, urban water use, especially industrial water use, has increased significantly. ...
