Problems solved by technology

Due to the various and mixed types of water pollutants, and the main water treatment agents currently used have a single function, it is necessary to add flocculants, corrosion inhibitors, fungicides and other agents to the water treatment system, and the treatment process is complicated.
There are a lot of equipment, complicated operation process, large dose of reagents, and various reagents will resist each other through various chemical reactions, resulting in reduced drug efficacy and poor adsorption capacity for heavy metal ions

Embodiment Construction

[0036] The adsorbent of the present invention is made of corn stalks and pine wood powder; after washing the corn stalks with clear water, put them in an oven, dry them at 80°C until the water content is ≤5.0%, and then crush them to 80 meshes and mix them with clean pine wood powder Mix by weight 1: 1, add the clear water accounting for 25% of the total weight of the material after mixing, then add the hydrolytic enzyme accounting for 2.1% of the total weight of the material after mixing, put it into an airtight container after uniform mixing, and control the temperature in the airtight container to After 16 hours of enzymolysis at 35°C, collect the enzymolyzed material, wash it with water, dehydrate it with a centrifuge, put it in a drying oven, and dry it at 80°C until the moisture content is ≤ 4.0%. In the carbonization furnace, under the condition of nitrogen protection, the temperature was raised to 330°C for pyrolysis and carbonization reaction. After 40 min of heat pres...

Abstract

The invention discloses a multifunctional ecological environment-friendly type sewage adsorbent and a preparation method, and belongs to the technical field of environment protection. The multifunctional ecological environment-friendly type sewage adsorbent is prepared from corn straw and pine dust through drying, crushing, enzyme hydrolyzing, washing, carbonizing and impregnating. Proved by test, the multifunctional ecological environment-friendly type sewage adsorbent can effectively remove the heavy metal ions in sewage, and can be widely applied to the field of sewage treatment.

Description

technical field [0001] The invention relates to the technical field of environmental pollution, in particular to a multifunctional ecological environment-friendly sewage adsorbent. Background technique [0002] Water is the source of human life and the basis of survival. With the development of industrial and agricultural production and the continuous increase of population, the problem of water environment has become a serious problem restricting human development and survival. The shortage of water resources and the deterioration of water quality are becoming more and more serious. With the rapid development of industrial technology, the problem of heavy metal pollution is becoming more and more serious. Man-made pollution mainly includes power plant emissions, coal combustion, metallurgy, coal mining, and traffic emissions. Heavy metal pollution is not only harmful to human health, but also affects children's intellectual growth. At present, the main treatment method f...
