Problems solved by technology

A large amount of silicate and alkaline substances brought by kaolin seal the bottom mud, causing hypoxia in the bottom mud, causing the death of benthic organisms, and even releasing harmful gases, further destroying the biological chain of the water body
Therefore, the use of kaolin for treatment is only a short-term action; the mechanical method is to dig out the silt of the whole lake, but it is difficult to implement it in large rivers and lakes
If it is to be implemented, it will require tens of billions of huge funds; the chemical method is to use chemical algicides to poison and kill cyanobacteria, and copper sulfate is commonly used in early ocean red tide control, and the effect is better, but divalent copper ions are harmful to biological larvae. Metamorphosis is teratogenic and copper sulfate is toxic, which c

Example Embodiment

[0031] Example 1

[0032] Weigh 100g of sodium silicate or tetramethylsilanol or tetraethylsilanol to prepare an aqueous solution with a concentration of 1M, and gradually add it to a nitric acid solution with a concentration of 1M. The solution also contains 1% foaming agent baking soda and 5 % silver nitrate, a gel was obtained with stirring. The gel was heated in an oven at 200°C for 24 hours, and then fired at 1000°C for 4 to 6 hours to form a molten silver-containing porous glass. After cooling to room temperature, it was pulverized with a ball mill and sieved to obtain powder. Silver-containing porous glass, the powder particle size is 10-100 microns, the pore size is 20-30 nm, and the silver content is 3% by weight in terms of silver, wherein the silver is Ag 2 O and AgO are combined with the porous skeleton of the porous glass, protected from light, and used for later use. Hereinafter referred to as material A.

Example Embodiment

[0033] Example 2 (high temperature sintering method)

[0034] Take the raw materials for conventional manufacturing of ceramics, after fully mixing, add 1-5% silver nitrate or silver phosphate, after fully mixing, add 1-3% high-temperature foaming material calcium carbide and mix evenly, then sinter at 900-1000 ℃ The silver-containing porous ceramics in a molten state are formed, cooled to room temperature, pulverized by a ball mill, and sieved to obtain a powdered silver-containing porous ceramics. The percentage is 1 to 3%, in which silver is Ag 2 O and AgO are combined with the porous skeleton of the porous ceramic, and stored in the dark for future use. Hereinafter referred to as material B.

Example Embodiment

[0035] Example 3

[0036] Take 1kg of diatomite powder and 1kg of kaolin powder, mix thoroughly, add 1L of 20% silver nitrate aqueous solution, stir well, leave it overnight, and then dry to form silver-containing porous diatomite-kaolin, and after cooling, pulverize with a ball mill , sieve to obtain powdery silver-containing porous diatomite-kaolin, the powder particle size is 50-200 microns, the pore size is 10-50 nm, and the silver content is 6% by weight in terms of silver, wherein silver is calculated as silver ions. It is combined with the porous skeleton of porous diatomite powder and kaolin powder through ionic bonds, and stored in the dark for future use. Hereinafter referred to as material C.

Abstract

The invention relates to an anti-pollution alga finishing agent and an application method thereof. The finishing agent is compounded by silver-containing multiaperture inorganic polymer material and polymeric flocculant, or nanometer silver natural biological polymer material or polymer material and made into powder, particle products; or the silver-containing multiaperture inorganic polymer material self mixes with resin to produce various spheres, sponge products, etc. The aperture of the silver-containing multiaperture inorganic polymer material is 5-50nm and the silver content is 0.01-10 percent (weight); the multiaperture inorganic polymer material(s) is one or a plurality of glass, ceramics, diatomite, kaoline, zeolite, molecular sieve and nanometer anion powder, therefore, silver is one or a plurality of Ag simple substance, Ag ion, Ag2O and AgO and is combined with the multiaperture framework of the multiaperture inorganic polymer materials. The invention has simple application and is suitable for treating water pollution caused by algae in rivers and pools and improving microenvironment of water body of aquatic product and fancy fishery cultivation.

Description

technical field [0001] The invention relates to a pollution-free algae treatment agent and its application method. It is especially suitable for controlling water pollution caused by cyanobacteria blooms in rivers and lakes, and improving the microenvironment of water bodies in aquatic fisheries and ornamental fisheries. Background technique [0002] While my country's economy continues to grow at a high speed, the biggest negative effect is that environmental pollution is becoming more and more serious. The quality of water environment in large rivers, rivers, lakes, reservoirs, etc. is deteriorating day by day, and the degree of eutrophication is serious. Because there are too many nutrients in the water body, aquatic organisms (mainly algae) reproduce in large numbers, and the respiration of algae and the decomposition of dead algae consume a large amount of oxygen, resulting in a serious anoxic state in the water body. In severe cases, cyanobacterial blooms will cover t...
