Problems solved by technology

There are few successful reports on the biological regeneration of activated carbon. The main disadvantage is that the biological method is only suitable for biodegradable pollutants, but not for non-biodegradable and toxic and harmful organic substances, and the residual final product is adsorbed. On the surface of activated carbon, the regeneration is incomplete; the high-temperature heating regeneration method has a huge loss of activated carbon, usually more than 10%, and the transportation cost is high

Abstract

The invention provides a new type of sulfate adsorption material for water body, with controllable pore size, which can not only ensure the filtration speed of water, but also have a very good adsorption effect on sulfate ions. There is no energy consumption in the treatment process, and only gravity filtration is needed. Yes, simple and environmentally friendly; after the adsorption material is used for a period of time, if the filtration speed cannot meet the requirements, it can be replaced; the replaced adsorption material can be used as a plant culture substrate, and sulfate ions can be absorbed by plants as a fertilizer.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a novel water body sulfate adsorption material. Background technique [0002] Under the background of the continuous increase of water pollution at home and abroad, activated carbon, as a high-efficiency adsorption material, has been widely used in the advanced treatment process of drinking water. Activated carbon can effectively remove a variety of different organic pollutants from water, but after long-term use, activated carbon continues to reach the state of organic matter adsorption saturation, and needs to be replaced or regenerated in time to ensure the water treatment effect. Activated carbon regeneration methods have been researched and applied at home and abroad. It is mainly divided into three categories: biological method, heating method and chemical method. There are few successful reports on the biological regeneration of activated carbon. The main disadvan...
