Embodiment 1

[0036] Embodiment 1, the preparation of modified diatomite

[0037] a. Dry diatomaceous earth, pass through a 100-mesh sieve to obtain fine powder, then add hydrochloric acid with a volume concentration of 8%, the solid-to-liquid ratio of the fine powder to hydrochloric acid is 1g:2mL, heat to 110°C for 3h, Cool, wash with water until neutral, and dry to obtain acidic diatomite powder;

[0038] b. adding nano-zinc oxide to the acidic diatomite powder obtained in step a and mixing uniformly, the weight ratio of the acidic diatomite powder and nano-zinc oxide is 1:0.5 to obtain mixture I;

[0039] c. dissolve xylitol in water and stir until completely dissolved, then add the mixture I obtained in step b and stir, the weight ratio of xylitol and mixture I is 6:1, form a uniform colloid, dry, grind, Instantly.

Embodiment 2

[0040] Embodiment 2, the preparation of modified diatomite

[0041] Dry diatomaceous earth, pass through a 100-mesh sieve to obtain a fine powder, then add hydrochloric acid with a volume concentration of 8%, the solid-to-liquid ratio of the fine powder to hydrochloric acid is 1g:3mL, heat to 110°C for 3 hours, cool, Wash with water until neutral, dry to obtain acidic diatomite powder;

[0042] b. adding nano-zinc oxide to the acidic diatomite powder obtained in step a and mixing uniformly, the weight ratio of the acidic diatomite powder and nano-zinc oxide is 1:0.6 to obtain mixture I;

[0043] c. Dissolve mannose in water and stir until completely dissolved, then add the mixture I obtained in step b and stir, the weight ratio of the mannose to mixture I is 8:1, form a uniform colloid, dry, grind, and obtain .

Embodiment 3

[0044] Embodiment 3, the preparation of wood ceramics

[0045] A. Dry the wood powder to a moisture content of <20%, crush and grind it and pass it through a 100-mesh fine sieve to obtain fine wood powder;

[0046] B takes by weight parts and is 70 parts of liquid epoxy acrylic resins with a solid content of 45%, 3 parts of low-temperature pyrolytic carbon, and 8 parts of Sn powder and stirs evenly to obtain a mixed solution;

[0047] C. Mix the fine wood powder obtained in step A and the mixed solution obtained in step B evenly in a weight ratio of 1:1, impregnate at normal temperature and pressure for 50 hours, dry, preheat in a heating furnace protected by inert gas, and gradually increase the temperature to 800°C, depressurize and extract the low-molecular components, then continue to heat up to 1200°C, carbonize in vacuum for 4 hours, and cool to obtain the product.

Abstract

The invention belongs to the technical field of sewage treatment and in particular relates to a sewage purifier and a preparation process thereof. The sewage purifier provided by the invention mainlyconsists of modified kieselguhr, wood ceramic, polyanionic cellulose, potassium permanganate, tea saponin, epoxy succinic acid and sodium thioctate. The sewage purifier provided by the invention is reasonable and scientific in formula, is capable of effectively increasing dissolved oxygen of city sewage and reducing contents of chemical oxygen demands, ammonia nitrogen, total phosphorus, petroleumand excrement escherichia coli in city sewage, and meanwhile is capable of effectively reducing the contents of heavy metals. The city sewage purified with the sewage purifier provided by the invention meets provisions of type IV in table 1 of the Environmental Quality Standards for Surface Water GB3838-2002 of the People's Republic of China, the environment pollution can be greatly reduced, andthe living quality of people can be improved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a sewage purifying agent and a preparation process thereof. Background technique [0002] With the continuous development of human society and the improvement of urbanization and industrialization, the aggravation of water pollution has become a global problem that needs to be solved urgently. At present, the main reason for the formation of sewage is that industrial wastewater, domestic sewage, and ground pollutants brought in by storm runoff cause excessive loads of organic pollutants in the water body. On the other hand, a large number of pollutants in the water body precipitate and accumulate in the bottom mud. The pollutants cannot be degraded in time to cause secondary pollution, and the pollutants in the sediment promote the reproduction of actinomycetes and cyanobacteria, further exacerbating the black and odor of the water body; Its temperature also...
