preparation example Construction

[0037] The preparation method of the inorganic nano flocculant of attapulgite loaded metal ion, its steps are as follows:

[0038] S1, screening the required semi-finished attapulgite clay;

[0039] S2. Soak the semi-finished attapulgite clay in dilute sulfuric acid solution and mix and stir for 3 to 5 hours;

[0040] S3, the mixed solution is taken out and put into a centrifugal dryer, the dilute sulfuric acid solution and the attapulgite clay are separated, and the separated dilute sulfuric acid solution can be recycled and put into S2 for reuse;

[0041] S4, washing the separated attapulgite clay with tap water until neutral;

[0042] S5, the washed attapulgite clay is centrifuged and dehydrated again;

[0043] S6, putting the dehydrated attapulgite clay into an oven and drying at 120°C;

[0044] S7. Soak the dried attapulgite clay in the mixed solution of aluminum, titanium, lanthanum and cerium with a molar ratio of 1: 0.002: 0.05: 0.01: 0.03 in a mass ratio of 1 to 2:...

Abstract

The invention relates to a high-performance, non-secondary pollution nano-flocculation agent suitable for flocculation, organic matter oxidation, and inorganic matter agglomeration and complexation in water cleaning treatment, in particular to an inorganic nano-flocculation agent with attapulgite-loaded metal ions and a preparation method thereof , the inorganic nano flocculant is made by mixing attapulgite clay with a mixed solution of aluminum, titanium, lanthanum and cerium and then drying. The inorganic nano-flocculation agent with attapulgite-loaded metal ions of the present invention, after separating the organic and inorganic pollutants free in the water body through coagulation deposition and water body, uses the catalyst loaded in the inorganic nano-flocculation agent with attapulgite-loaded metal ions to carry out catalytic oxidation The reaction can oxidize and decompose the pollutants in the sediment, and prevent the transfer of pollution sources.

Description

technical field [0001] The invention relates to a high-performance, non-secondary pollution nano-flocculation agent suitable for flocculation, organic matter oxidation, and inorganic matter agglomeration and complexation in water cleaning treatment, in particular to an inorganic nano-flocculation agent with attapulgite-loaded metal ions and a preparation method thereof . 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 countries ...
