Abstract

The invention discloses a straw type water treatment material. The straw type water treatment material is prepared from components in parts by weight as follows: 35-45 parts of straw, 8-12 parts of 2-ethylacrylic acid, 6-10 parts of methylene-disulfonic acid, 3-7 parts of potassium citrate, 2-5 parts of stearamide, 1-4 parts of imibenconazole, 3-6 parts of clethodim, 5-9 parts of kaempferol, 7-13 parts of diethyl oxalate, 12-18 parts of polyvinyl alcohol, 10-20 parts of diethylene glycol ethyl ether and 15-25 parts of bis(2-butyl) ether. The water treatment material has a good adsorption effect on heavy metal ions such as Fe<2+> and Se<3+> in wastewater, and a new try is provided for waste utilization of straw.

Description

technical field [0001] The invention belongs to the field of waste water treatment materials, in particular to a straw-based water treatment material and a preparation method thereof. Background technique [0002] Water resources are very important to living organisms and humans. All life activities originate from water. Water in our body also accounts for 65% of our body weight. When the water shortage of the human body is 1%-2%, you will feel thirsty; when the water shortage is 5%, you will have dry mouth, unconsciousness, and even hallucinations; when the water shortage reaches 15%, it will affect your life. . Water is not only what all creatures in the world depend on, it is also indispensable for industrial and agricultural production. Mining, metal smelting, metal processing and chemical production all require water, which also produces a large amount of wastewater, which cannot be directly discharged into rivers or used. For a long time, in people's impression, w...
