Abstract

The invention discloses a magnetic polyacrylamide modified sewage treatment agent. The agent comprises the following raw materials in parts by weight: 10-13 parts of magnetic polyacrylamide, 1-2 partsof trichloroisocyanuric acid, 2-3 parts of calcium acetylacetonate, 70-80 parts of diatomite, and 0.6-1 part of oleic diethanolamide. The polyacrylamide and magnetic oxide also have good cooperativeadsorption effects, and the product has better sewage purifying effects; diatomite is also added, adsorption performance is further improved, raw materials are reasonably matched without secondary pollution, magnetic separation is employed, and usage is convenient.

Description

technical field [0001] The invention belongs to the field of water treatment, and in particular relates to a magnetic polyacrylamide modified 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, th...
