High-efficient sewage purification material

Abstract

The invention discloses a high-efficient sewage purification material. The material comprises, by mass, 100 parts of modified straw fiber, 15-30 parts of modified bentonite, 5-12 parts of nano filler,5-16 parts of activated carbon and 10-28 parts of polyving akohol. According to the high-efficient sewage purification material, the modified straw fiber which is adopted as a main body, polyving akohol which is mainly adopted as an adhesive and a compatilizer, the composite nano filler, the modified bentonite and the activated carbon are used for preparing the purification material; the nano filler and the activated carbon are inorganic materials. According to the high-efficient sewage purification material, a water purification material is obtained through organic-inorganic composite preparation, and the water purification material is mainly used for purifying heavy metals in water; the modified straw fiber is adopted as a matrix, combined with the water purification material to obtaina high-tech water purification material, and the high-efficiency sewage purification material is more environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of sewage purification materials, and in particular relates to a high-efficiency sewage purification material. Background technique [0002] In recent years, with the rapid development of industry, the problem of water pollution has become increasingly prominent; however, with the continuous improvement of people's material living standards, higher requirements have been put forward for water quality. On July 1, 2007, the newly revised "Drinking Water Sanitation Standard" (GB 5749-2006) was officially implemented, and the limits of some indicators of water quality are more stringent. On June 25, 2008, the state issued 11 new and more stringent industry emission standards including pulp and paper, electroplating, fermentation, etc. This has important practical significance for protecting the environment, ensuring people's drinking water health and improving people's quality of life.

AI Technical Summary

Problems solved by technology

[0003] General sewage is mainly COD, nitrogen compounds and heavy metals that exceed the standard. However, in terms of the current water pollution characteristics, heavy metal ions, soluble organic substances and refractory compounds in water are increasing year by year, and the current conventional water treatment methods have no effect on this series of pollution. It is difficult to achieve one-time treatment to meet the standard. At the same time, many current water treatment chemicals may also produce secondary pollutants that are harmful to the environment, which will undoubtedly have an adverse impact on environmental protection and sustainable development.

The treatment of heavy metal ions in sewage generally adopts precipitation method, oxidation-reduction method, electrolysis method, ion exchange method, etc. Now it is commonly used to use nano-materials to settle heavy metal ions, but nano-materials will release metal ions during water treatment. secondary pollution of water
