Embodiment Construction

[0017] The present invention will be described in detail below through specific examples.

[0018] A modified silt activated carbon adsorbent added with essential oil of phyton, made of the following raw materials in parts by weight (kg): sludge 145, corn stalks 15, peanut shells 21, manganese ore powder 12, zinc chloride 46, silicic acid Magnesium 16, Silicon Dioxide 7, Polyvinyl Alcohol 4, Polyacrylamide 5, Zeolite Powder 8, Phytondo Essential Oil 2, Aluminum Sulfate 6, Appropriate amount of distilled water;

[0019] A kind of modified silt activated carbon adsorbent that adds fendo essential oil according to the present invention is made by the following specific steps:

[0020] (1) Air-dry the sludge from the sewage treatment plant under natural conditions, and then dry it in an oven at 110°C for 18 hours. After cooling, grind it into sludge particles with a particle size of 1-3mm for use;

[0021] (2) Dry the corn stalks and peanut shells in an oven at 80°C until they re...

Abstract

The invention discloses a phytoncide essential oil-added modified sludge activated carbon adsorbent which is characterized by being prepared from the following raw materials, by weight, 100-150 parts of sludge, 13-17 parts of corn straw, 15-24 parts of peanut shell, 10-15 parts of manganese ore powder, 30-50 parts of zinc chloride, 13-16 parts of magnesium silicate, 5-8 parts of silicon dioxide, 3-5 parts of polyvinyl alcohol, 3-5 parts of polyacrylamide, 7-11 parts of zeolite powder, 2-4 parts of phytoncide essential oil, 5-7 parts of aluminum sulfate and a proper amount of distilled water. By interaction of the added phytoncide essential oil, tourmalinite powder, borax, activated alumina and sludge activated carbon, adsorptivity and antiseptic property of activated carbon are enhanced. The adsorbent is nontoxic and pollution-free, is harmless to the health of human body, has a good effect when used in water purification and is beneficial to body health. The adsorbent provided by the invention is nontoxic and environmentally friendly, has a simple preparation technology, has a wide source of materials, has good chemical stability and high mechanical property and is worthy of popularization.

Description

technical field [0001] The invention relates to the field of adsorbents, in particular to a modified sludge activated carbon adsorbent added with phytondo essential oil and a preparation method thereof. Background technique [0002] With the acceleration of urbanization, the increase of urban population and the strengthening of environmental protection awareness, the discharge of urban industrial wastewater and domestic sewage is increasing, the rate of urban sewage treatment is also increasing year by year, and the sludge generation rate of sewage plants is also increasing sharply. The sludge of the sewage treatment plant has a high water content, a large amount of organic matter, toxic and harmful substances, and semi-dry solid waste with complex rheology. It has a large capacity, is easily corrupted, unstable, and has a bad smell. cause serious environmental pollution. Activated carbon is a porous adsorption material with rich pore structure, high specific surface ar...
