Problems solved by technology

[0004] Nowadays, with the continuous advancement of industrialization and urbanization, environmental pollution has increased simultaneously, and due to poor management of sewage treatment and ineffective supervision, many water sources have been polluted to varying degrees, mainly manifested in the increase of ammonia nitrogen and organic matter in water, the accelerated process of "eutrophication", and the growth of algae. Breeding, resulting in water hypoxia, black and smelly, ammonia nitrogen in water is further digested into NO under the action of Nitrosobacillus 2 - , NO 3 - , will cause varying degrees of harm to human health. Tap water from polluted water sources often has peculiar smell, sensory discomfort, and bad taste, which directly affect residents' drinking.

Embodiment 1

[0019]

[0020] The preparation method is: (1) crush the vermiculite into granules or powders below 5mm; (2) add sulfuric acid to a concentration of 10% to 50%; (3) put the materials (1) and (2) into the decomposition vessel Add activated carbon and polyaluminum chloride, heat to 70-100°C for 2-10 hours, and stir; (4) After filtering and separating the materials obtained in step (3), the finished product is prepared. The mesh number of the filter is 100 to 800 mesh.

[0021] The present invention adopts natural minerals as raw materials, has rich element content, has no toxic side effects, is safe and environmentally friendly.

Embodiment 2

[0023]

[0024] The preparation method is the same as above.

[0025] It is easy to use, and only needs to be put into the water to be treated and stirred evenly to meet the treatment requirements without adding additional additives.

Embodiment 3

[0027]

[0028] The preparation method is the same as above.

[0029] This product has a metal inorganic salt content of more than 20% and is an acidic liquid with pH=1~2. When it is used in water and sewage, it has strong oxidizing power. Under the action of rich mineral element ions, water molecules It will be quickly separated from the soluble dirt in the water, and the separated dirt will become inactive substances, which will be aggregated and precipitated, so as to achieve the purpose of deodorization and removal of odor.

[0030] This product can be used to purify drinking water; it can also be put into sewage or feces in a certain amount to achieve the effects of coagulation, precipitation and deodorization of dirt. The waste residue after treating manure with this product can be used as farmyard manure. The preparation process of the invention is simple, the production cycle is short, the operation is simple, the production cost is low, the transportation and storage are ...

Abstract

The invention provides an efficient vermiculite water purification agent and a preparation method thereof. The water purification agent is composed of vermiculite, active carbon, polyaluminum chloride and sulfuric acid. The preparation method comprises the following steps: 1, crushing vermiculite to form below 5mm granules or powder; 2, adjusting sulfuric acid to the concentration of 10-50%; 3, adding a material obtained in step 1 and a material obtained in step 2 to a decomposition container, adding active carbon and polyaluminum chloride, heating to 70-100DEG C, carrying out heat insulation for 2-10h, and stirring while the heat insulation; and 4, filtering a material obtained in step 3, separating, and blending to obtain a finished product. The mesh of a filter screen is 100-800.

Description

Technical field [0001] The invention relates to the field of water purifying agents, in particular to a high-efficiency vermiculite water purifying agent and a preparation method thereof. Background technique [0002] In recent years, extensive investigations and studies have been carried out on the endocrine disrupting activity of environmental chemicals. A large number of animal epidemiological data indicate that many environmental chemicals can interfere with the endocrine function of animals, and clinically they are characterized by reproductive disorders, birth defects, developmental abnormalities, metabolic disorders and certain cancers. Human epidemiological studies have shown that human reproductive disorders, developmental abnormalities and certain cancers such as breast cancer, testicular cancer, and ovarian cancer are related to endocrine interference. There are hundreds of chemicals that have been proven to be endocrine disruptors. The 1998 survey of water pollutant...
