Abstract

The invention discloses a microporous coating water pollution treating agent. The microporous coating water pollution treating agent is prepared from, by weight, 100-140 parts of tetraethoxysilane, 4-7 parts of aluminum sulfate, 2-3 parts of pore-forming agent, 0.1-0.2 part of sucrose acetate isobutyrate, 1-2 parts of sodium tripolyphosphate, 40-50 parts of kieselguhr and 2-3 parts of barium stearate. Accordingly, the tetraethoxysilane serves as a precursor and is hydrolyzed in an aqueous solution, in the hydrolysis process, the pore-forming agent is adopted for treating, surface microporosityof a finished product sol can be effectively improved, when hydrolysis is conducted to form the sol, the kieselguhr is coated and modified, and then the composite material with the communicated innermicropore and outer micropore is obtained; the microporous coating water pollution treating agent has the very good water purification effect, the stability is high, the repeated utilization rate isgood, the environmental friendliness is good, and no secondary pollution exists.

Description

technical field [0001] The application belongs to the field of water treatment, and in particular relates to a microporous-coated water pollution 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 a...
