Abstract

The invention discloses a coated sewage treatment agent which is prepared from the following raw materials in parts by weight: 16-20 of sodium carboxymethylcellulose, 4-6 of oxidized polyethlene wax,0.7-1 of 2-sulfhydrylbenzimidazole, 1-2 of stearamide, 3-5 of mannitol, 30-40 of modified sol, 70-90 of scolecite and 10-14 of polyacrylamide. For the coated type sewage treatment agent provided by the invention, by adopting sodium carboxymethylcellulose for coating treatment, the stability strength of the structure of a finished product is effectively improved; and the material provided by the invention has very good adsorption performance and good stability without containing polluting substances and causing secondary pollution and is 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 coated sewage treatment agent and a preparation method thereof. Background technique [0002] Due to population growth and economic development, a series of problems affecting the quality of resources caused by excessive exploitation and unreasonable development and utilization of resources have directly threatened the survival of us and future generations; sewage treatment technology has a great impact on water saving, energy saving, etc. The problem plays a very important role, but at the same time, the use of sewage treatment chemicals also has a certain impact on the environment. In the cooling water system, in various occasions where the water temperature is higher than the ambient temperature, the scaling of calcium carbonate and other inorganic salts will bring serious consequences. In recent years, in the field of water treatment, the application of ...
