Embodiment 1

[0027] A domestic sewage treatment agent, the raw materials are: 15 parts of polyferric chloride, 25 parts of sepiolite, 30 parts of bentonite, 10 parts of sodium hydroxide, 15 parts of polyacrylamide, 10 parts of sodium carbonate, bio-based porous composite 5 parts of materials, 5 parts of modified silkworm sand-based hierarchical porous carbon materials. First weigh the raw materials according to the ratio of raw materials, then mix sepiolite, sodium carbonate, and bio-based porous composite materials, crush them, pass through 100 mesh, and put them into a container, then add polyacrylamide and polyferric chloride to continue stirring and mixing After 20 minutes, add sodium hydroxide and stir and mix for 15 minutes. Control the mixing temperature to less than 55°C. Finally, add the modified silkworm excrement-based hierarchical porous carbon material, stir and mix evenly, and the domestic sewage treatment agent can be obtained.

Embodiment 2

[0029]A domestic sewage treatment agent, the raw materials are: 12 parts of polyferric chloride, 30 parts of sepiolite, 25 parts of bentonite, 12 parts of sodium hydroxide, 12 parts of polyacrylamide, 12 parts of sodium carbonate, bio-based porous composite 3 parts of materials, 8 parts of modified silkworm sand-based hierarchical porous carbon materials. First weigh the raw materials according to the raw material ratio, then mix the sepiolite, sodium carbonate, and bio-based porous composite materials, crush them, pass through 50 mesh, and put them into a container, then add polyacrylamide and polyferric chloride to continue stirring and mixing After 15 minutes, add sodium hydroxide and stir and mix for 20 minutes. Control the mixing temperature to less than 55°C. Finally, add the modified silkworm excrement-based hierarchical porous carbon material, stir and mix evenly, and the domestic sewage treatment agent can be obtained.

Embodiment 3

[0031] A domestic sewage treatment agent, the raw materials are: 13 parts of polyferric chloride, 28 parts of sepiolite, 28 parts of bentonite, 10 parts of sodium hydroxide, 15 parts of polyacrylamide, 10 parts of sodium carbonate, bio-based porous composite 5 parts of material, 6 parts of modified silkworm excrement-based hierarchical porous carbon material. First weigh the raw materials according to the ratio of raw materials, then mix sepiolite, sodium carbonate, and bio-based porous composite materials, crush them, pass through 100 mesh, and put them into a container, then add polyacrylamide and polyferric chloride to continue stirring and mixing After 10 minutes, add sodium hydroxide and stir and mix for 20 minutes. Control the mixing temperature to less than 55°C. Finally, add the modified silkworm excrement-based hierarchical porous carbon material, stir and mix evenly, and the domestic sewage treatment agent can be obtained.

Abstract

The invention discloses a domestic sewage treatment agent and a preparation method of the domestic sewage treatment agent. The domestic sewage treatment agent comprises the following raw materials inparts by weight: 12-15 parts of polyferric chloride, 20-30 parts of meerschaum, 5-10 parts of modified silkworm excrement based porous carbon material, 10-15 parts of sodium hydroxide, 12-15 parts ofpolyacrylamide, 10-15 parts of sodium carbonate and 1-5 parts of bio-based porous composite material. According to the treatment agent, two novel biological carbon materials are added, so that the adsorption purification capacity of the sewage treatment agent is improved; the treatment agent can effectively treat domestic sewage of residents under matching of the other raw materials, and is good in treatment effect, lower in cost and stable in performance; and treated pollution reaches a national sewage discharge standard.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a sewage treatment agent and a preparation method thereof. Background technique [0002] With the improvement of living standards and the increase of water consumption, the amount of domestic sewage produced is also increasing. How to effectively treat domestic sewage, reduce and reduce the pollution to the environment has always been a research topic. At present, there are many methods for treating domestic sewage, such as physical, chemical, biological, and comprehensive methods. The physical method is to recover the undissolved suspended pollutants in the sewage through physical separation, filtration, centrifugation and so on. Such a physical method is simple, but it can only do basic treatment, and the treatment effect is not good, and the pollutants dissolved in the water cannot be treated, so the efficiency is low. Biological treatment is to convert...
