Embodiment Construction

[0024] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0025] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0026] The invention discloses a method for preparing an inorganic nano-flocculation agent with attapulgite loaded with metal ions. The inorganic nano-flocculation agent is made by mixing attapulgite clay with a mixed solution of aluminum, titanium, lanthanum and cerium, and then drying.

[0027] The steps described are as follows,

[0028] S1, screening the required semi-finished attapulgite clay;

[0029] S2, soak the semi-finished attapul...

Abstract

The invention relates to a nano-flocculant which is applicable to flocculation, organic matter oxidation and inorganic matter agglomeration and complexation of water cleaning treatment, has high performance and is free of secondary pollution, in particular to an inorganic nano-flocculant adopting attapulgite loaded with metal ions and a preparation method of the inorganic nano-flocculant. The inorganic nano-flocculant is prepared through mixing and drying of attapulgite clay and a mixed solution of aluminum, titanium, lanthanum and cerium. According to the inorganic nano-flocculant adopting the attapulgite loaded with the metal ions, a catalyst loaded in the inorganic nano-flocculant adopting the attapulgite loaded with the metal ions is used for catalytic oxidation after organic and inorganic pollutants which are free in water are separated from the water through coagulation deposition, so that the pollutants in sediment are oxidized and decomposed.

Description

technical field [0001] The invention relates to a nano-flocculation agent with high performance and no secondary pollution, which is suitable for flocculation, organic matter oxidation, and inorganic matter agglomeration and complexation in water cleaning treatment, in particular to a preparation method of an inorganic nano-flocculation agent with attapulgite-loaded metal ions. Background technique [0002] With the development of society, a large amount of wastewater containing organic matter will be produced in people's life. If these wastewater is discharged directly without treatment, it will cause very serious harm to the environment. Therefore, the treatment of organic wastewater has become the current domestic and foreign environment. A difficult problem to be solved in the field of conservation technology. [0003] Flocculant is an indispensable and important link in the existing water treatment process. Because of its large consumption, scientists from various coun...
