Problems solved by technology

However, there are some problems in using activated carbon as a water treatment agent. For example, the adsorption capacity of activated carbon needs to be further improved, and its adsorption is physical adsorption, which is easy to desorb during the adsorption process, causing secondary pollution.

Abstract

The invention discloses a composite filter material and a preparation method and application thereof. The composite filter material is made from, by weight, 10-18 parts of polyepoxysuccinic acid, 1-8 parts of sodium alginate, 5-12 parts of tea saponins, and 36-44 parts of hydroxypropyl starch. Prepared tea saponin solution and hydroxypropyl starch are heated and stirred, polyepoxysuccinic acid is added, sodium alginate is added, stirring is performed, and ultrasonic treatment, stirring to dryness and high-temperature calcining are performed to obtain the composite filter material. The composite filter material prepared herein is efficient in adsorbing heavy metals and improving water purification effect with no secondary pollution, has the advantages of high adsorbing capacity, short adsorbing time, low addition, good thermal stability, plasticity, high compressive strength and the like, is easy to recycle and is reusable after being recycled; the preparation process is simple and is easy to perform, preparation parameters are stable, and the composite filter material that is prepared has low preparation cost and is suitable for industrial large-scale production.

Description

technical field [0001] The invention relates to the technical field of water treatment materials, in particular to a composite filter material and its preparation method and application. Background technique [0002] Drinking water refers to water that can be directly supplied to the human body for drinking without treatment. Water is the main component of body fluid, and is an important substance that constitutes cells, tissue fluid, plasma, etc. As the medium of all chemical reactions in the body, water is a platform for the transportation of various nutrients and substances. With the development of industry, the degree of pollution of urban drinking water sources is increasing. At the same time, with the improvement of living standards, people's requirements for drinking water quality and drinking water quality standards are becoming more and more stringent. The activated carbon materials currently on the market for water treatment mainly use physical adsorption to sepa...
