Soil-based sewage treatment flocculant and preparation technology thereof

Abstract

The invention discloses a flocculant for soil-based sewage treatment. The composition and mass parts are: 9-15 parts of sodium lignosulfonate, 5-10 parts of lutetium oxide, 3-8 parts of aluminum oxide, and 5-7 parts of calcium oxide 4-9 parts of kaolin, 3-10 parts of wood vinegar, 2-6 parts of water glass, 5-7 parts of dendrobium leaf powder, 4-8 parts of sodium sulfite, 6-9 parts of ceramic fiber, 4-8 parts of caustic soda , 6-9 parts of mica, 3-10 parts of feldspar, 7-9 parts of ferrous sulfate, 3-8 parts of clay, 2-6 parts of gypsum, 6-10 parts of boron nitride, 1-5 parts of carboxymethyl cellulose 1-3 parts of epoxy resin, 8-13 parts of aluminum silicate fiber, 11-13 parts of cordierite powder, 9-14 parts of bentonite, 7-15 parts of alumina, 5-8 parts of clay, 1 part of radish leaf powder -3 copies. The flocculant of the present invention has strong adsorption, flocculation, transformation, separation, and precipitation effects on harmful substances in polluted water bodies, and has good bactericidal, antibacterial, deodorizing, and decolorizing effects, and can effectively eliminate harmful substances in polluted water bodies. pollutants.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a soil-based sewage treatment flocculant and a preparation process thereof. Background technique [0002] With the increase of urban population and the development of industrial and agricultural production, the amount of sewage discharge continues to increase, and water pollution damages the ecological environment, seriously threatening human survival and health. Therefore, the problem of sewage purification treatment has been paid more and more attention. However, due to the constraints of economic conditions and many objective conditions, only part of the urban and rural sewage has been treated, and there is still a lot of sewage, especially some domestic sewage, which cannot enter the sewage treatment plant for purification treatment, and is directly discharged into ditches and rivers, forming a large number of sewage rivers, smelly Ditch phenomenon; non-...

AI Technical Summary

Problems solved by technology

[0005] Microbial flocculant is obtained by using microbial technology to ferment and extract bacteria, fungi and other microorganisms. It has the advantages of easy biodegradation and high safety. It is an efficient, non-toxic and non-secondary pollution flocculant, which can The inherent defects of traditional inorganic polymers and synthetic organic polymer flocculants finally achieve pollution-free discharge, but their cost is relatively high, and the growth and reproduction of microorganisms are greatly affected by the environment. As the environment changes, its scope of use is also affected. limit
