Abstract

A compound adsorbing material is disclosed in the invention, which comprises a first adsorbing material component and a second adsorbing material component combining outside the first adsorbing material component, wherein the volume of organic matter molecule absorbed by the first adsorbing material component is smaller than that absorbed by the second adsorbing material component, and the first adsorbing material and the second adsorbing material are formed by micropore adsorbing material and modified inorganic clay mineral, respectively. The adsorbing material of the invention uses fractional adsorption so that the first adsorbing material inside absorbs micromolecule organic matter while the outside second adsorbing material absorbs organic matter or oil particle having larger volume, thereby the organic matter blocking the micropore is prevented. The adsorbing material of the invention is easy to regenerate and has high adsorption rate, so that while treating organic matter waste water by the adsorbing material of the invention, the treating process is simplified, and investment and cost for treating waste water can be reduced.

Description

technical field

[0001] The invention relates to a composite adsorption material suitable for wastewater treatment, in particular to a composite adsorption material for the treatment of oily wastewater and wastewater containing refractory organic pollutants. Background technique

[0002] At present, water resources are in short supply worldwide, and water pollution is becoming more and more serious. How to rationally utilize water resources, reduce sewage discharge, and protect the water environment has attracted widespread attention from all parties. Sewage reuse technology has emerged as the times require. Sewage reuse can not only save a lot of fresh water, but also greatly reduce sewage discharge and protect the water environment.

[0003] A variety of wastewater reuse technologies have been developed, among which the membrane process is a competitive technology. Standard sewage usually contains a certain amount of organic or oily substances, and the chemical oxygen dema...
