Heavy self-settling sewage treatment agent and preparation method thereof

Abstract

The invention discloses a heavy self-settling sewage treatment agent which comprises the following raw materials in parts by weight: 1-2 parts of saturated octadecanamide, 100-120 parts of diatomaceous earth, 3-5 parts of dodecyl mercaptan, 0.8-1 part of polyglycerol-10 oleate, 1-2 parts of hexadecyl trimethyl ammonium chloride, 3-5 parts of maleic anhydride, 5-7 parts of oxidized polyethylene wax, and 20-30 parts of tetraethyl orthosilicate; according to the heavy self-settling sewage treatment provided by the invention, the tetraethyl orthosilicate is used as a precursor, and is hydrolyzed by dispersing into a saturated aqueous solution of octadecylamide, and the obtained sol is blended with the organically modified diatomaceous earth, so that the compatibility between the diatomaceous earth and the sol is effectively improved. Therefore, the strength of stability of a finished treatment agent is improved; and the treatment agent provided by the invention is good in safety and environmental protection, high in repeated utilization rate and excellent in comprehensive performance.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a heavy self-settling sewage treatment agent and a preparation method thereof. Background technique [0002] In recent years, in the field of water treatment, the application of alkaline water treatment technology that does not adjust the pH value is increasing. Among them, the addition of corrosion and scale inhibitors, low-phosphorus, and phosphorus-free formulations are more and more widely used. Phosphorus-free green Water treatment agents have become a hot topic in the research of water treatment agents at home and abroad. The scientific use of water treatment chemicals can effectively prevent corrosion and scaling, thereby improving the utilization rate of equipment and water to achieve the purpose of saving water and energy; at present, there are many methods to deal with water pollution problems such as physics, chemistry, biology, and comprehensive met...

Problems solved by technology

The scientific use of water treatment chemicals can effectively prevent corrosion and scaling, thereby improving the utilization rate of equipment and water to achieve the purpose of saving water and energy; at present, there are many methods to deal with water pollution problems such as physics, chemistry, biology, and comprehensive methods , but many physical methods have problems of poor treatment effect and unstable treatment rate; biological methods are too expensive to be popularized and used; chemical methods are mostly used to treat sewage, but the existing sewage treatment agents have two components in their reagents Secondary pollution problems will also have a certain impact on the environment, and the separation of existing treatment agents is relatively difficult
