Embodiment 1

[0041] Measure 30 mL of absolute ethanol, place it in a beaker, and stir on a magnetic stirrer; add 10 mL of butyl titanate to it, stir for 8 minutes, add nitric acid to adjust pH=2; then slowly add 5 mL of distilled water to it and stir. After 8 minutes, a transparent titanium dioxide sol was obtained; while stirring, weigh 15g of montmorillonite and add it to the titanium dioxide sol (at this time, the ratio of butyl titanate to montmorillonite is 2mmol: 1g, titanium dioxide and montmorillonite The ratio is 2mmol:1g, the molar amount of butyl titanate and titanium dioxide is the same), to obtain a montmorillonite / titanium dioxide composite solution;

[0042] Separately weigh 0.12g of polyaluminum chloride to make the weight ratio of polyaluminum chloride to titanium dioxide 0.05; dissolve it in 0.24mL of distilled water and add it to the montmorillonite / titanium dioxide composite solution; continue stirring for 2h The gel is obtained; the gel is dried in an oven at 70° C., and ...

Embodiment 2

[0045] Measure 30mL of absolute ethanol, place it in a beaker, and stir on a magnetic stirrer; add 10mL of butyl titanate to it, stir for 8min, add nitric acid to adjust pH=2; then slowly add 5mL of distilled water to it and stir. After 8 minutes, a transparent titania sol was obtained; while stirring, weigh 15g of montmorillonite and add it to the above titania sol (at this time, the ratio of butyl titanate to montmorillonite is 2mmol:1g, titanium dioxide and montmorillonite The ratio of the stone is 2mmol:1g,) to obtain the montmorillonite / titanium dioxide composite solution;

[0046] Weigh 0.6g polyaluminum chloride to make the weight ratio of polyaluminum chloride to titanium dioxide 0.25; dissolve it in 1.2mL of distilled water and add it to the above montmorillonite / titanium dioxide composite solution; continue stirring for 2h Get the gel; place it in an oven at 70°C and dry it to get a montmorillonite composite (montmorillonite supported polyaluminum chloride / titanium diox...

Embodiment 3

[0049] Measure 30 mL of absolute ethanol, place it in a beaker, and stir on a magnetic stirrer; add 10 mL of butyl titanate to it, stir for 8 minutes, add nitric acid to adjust pH=2; then slowly add 5 mL of distilled water to it and stir. After 8 minutes, a transparent titania sol was obtained; while stirring, weigh 15g of montmorillonite and add it to the above titania sol (at this time, the ratio of butyl titanate to montmorillonite is 2mmol:1g, titanium dioxide and montmorillonite The ratio of the stone is 2mmol:1g,) to obtain the montmorillonite / titanium dioxide composite solution;

[0050] Weigh 1.2g of polyaluminum chloride to make the weight ratio of polyaluminum chloride to titanium dioxide 0.5; dissolve it in 2.4mL of distilled water and add it to the montmorillonite / titanium dioxide composite solution; continue stirring for 2h The gel is obtained; it is placed in an oven at 70° C. and dried to obtain a montmorillonite composite (montmorillonite supported polyaluminum ch...

Abstract

The invention relates to a turface composite for removing blue algae, and a preparation method thereof, which are mainly used for treating water pollution. The turface composite for removing blue algae and the preparation method thereof are provided and characterized in that the preparation method comprises the following steps: 1) preparing a titanium dioxide solution; 2) preparing a turface / titanium dioxide composite solution : adding turface into the titanium dioxide solution prepared in step 1) to obtain the turface / titanium dioxide composite solution; 3) churning while dissolving polyaluminium chloride into water for preparing a solution with the mass fraction of 30%-70%, and dropping the solution into the turface / titanium dioxide composite solution prepared in step 2); continuing to churn for 1-3 hours to form gel; and placing the gel into an oven for drying and grinding to obtain the turface composite for removing blue algae. The method has the advantages of wide raw material source, low price, capability of rapidly and effectively cleaning blue algae in water areas, simple technological process and easiness for realizing industrial production.

Description

Technical field [0001] The invention relates to a montmorillonite composite for removing blue algae and a preparation method thereof, which are mainly used for the treatment of water pollution. Background technique [0002] In recent years, due to the increasing eutrophication of water bodies, cyanobacteria blooms have exploded in large areas, releasing toxic substances, making the water smelly and unpleasant, reducing dissolved oxygen, and killing a large number of fish, which has seriously affected the normal life and production of human beings. So how to control Cyanobacteria pollution has become a major problem that is being explored hard at home and abroad. [0003] At present, the main methods for removing cyanobacteria in waters include physical, chemical, biological and physical chemical methods. [0004] Physical methods mainly take measures such as ultrasonic destruction and mechanical removal, such as "Mechanical Removal of Blue Algae Blooms in the Eutrophic Lake Dianchi ...
