Water treatment materials and production thereof

Abstract

A water-treatment material and its production are disclosed. The material is prepared by taking a loosen and light substance as skeleton material, adding into concave-convex bar clay with proportion=(50-80): (20-50), mixing, mixing, adding into water, agitating, shaping, air drying, calcining at 800-1100 Deg C. for 4hrs, obtaining products, cooling to room temperature and spraying microbe with bacillus onto surface. It achieves good degradation and adhering effect, high efficiency and low cost.

Description

Technical field: [0001] The invention relates to the field of water purification materials, in particular to water treatment materials and a manufacturing method thereof. Background technique: [0002] At present, the widely used water treatment materials include activated carbon, medical stone, zeolite, etc. Attapulgite clay, as an adsorption filter material in water treatment, has attracted more and more attention in the industry due to its superior performance, abundant sources, and low price. [0003] Attapulgite clay is a natural non-metallic clay mineral. It is a crystalline hydrated magnesium aluminum silicate mineral with a unique layer chain crystal structure and very small (about 0.01mm×1mm) rod-like and fibrous crystals. form, so this mineral is able to exhibit excellent properties in many ways. [0004] Generally speaking, attapulgite clay (ore) is acid-washed to remove non-clay components, and heat treatment can make it lose water. Before 300°C, it loses adsorp...

Problems solved by technology

In recent years, experts, scholars, and scientific and technical personnel in the field of water treatment have made a lot of useful discussions on the application of attapulgite clay, such as "Attapulgite Clay and Its Application in Water Treatment" in "Industrial Water Treatment" in 2003, Classified and discussed the application of attapulgite clay in the field of water treatment, analyzed existing problems, and put forward corresponding opinions and suggestions; "Experiment of Attapulgite Clay Treatment of Urban Wastewater" in "Jiangsu Geology" in 2000, "Environmental Pollution and "Research on Attapulgite Clay Treatment of Printing and Dyeing Wastewater" in "Prevention and Control" and "Research on Phosphate Removal by Attapulgite Powder Soil Adsorbent" in "Comprehensive Utilization of Mineral Resources" in 1995, etc., have carried out a lot of research on attapulgite clay as a water treatment agent. Experiments and studies have shown that its decolorization, deodorization, adsorption and degradation of organic matter and harmful substances are superior to existing materials, but in the prior art of attapulgite clay for water treatment, most of them use attapulgite clay powder, or several The powders mixed with minerals are also partially made of solids, but these solids are formed at low temperature and will collapse after being put into water (become powder again). Suspended state, forming a high-viscosity suspension. Although the water treatment effect is good, it is difficult to recycle it. It can only be allowed to flow away with the treated water. The treated water cannot be recycled, and there are still environmental pollution and waste of resources.
