Embodiment 1

[0034] Qualified diatomite ore raw materials (SiO 2 Content 50~70%, Al 2 o 3 Content ≥ 8%, Fe 2 o 3 ≤10%, based on Pu, heavy metal content ≤0.05%, organic matter content 7-15%) are sent into shaft kiln 3, and the temperature is controlled at 750-800° C. by combustion of organic matter. Decompose organic matter and carbonate, activate kaolinite in diatomite ore, and the ore after roasting for 3 hours is discharged from the lower part of the shaft kiln after being cooled by air. The roasted and cooled material is sent to the vertical mill 5 by the leather conveyor 4, and the crushed powder is sent to the upper powder selector by the exhaust fan 18. In the powder separator, quartz, feldspar, and iron ore are too hard to be finely ground, so the coarser particles are blocked and removed, and the diatomite can be purified. The purified diatomite is separated from gas and solid by a bag dust collector, and the powdery diatomite is fed quantitatively by a screw conveyor 7, and t...

Embodiment 2

[0037] Another qualified diatomite ore raw material (SiO 2 Content 50~70%, Al 2 o 3 Content ≥ 8%, Fe 2 o 3 ≤10%, based on Pu, heavy metal content ≤0.05%, organic matter content 5-15%) is sent into shaft kiln 3, and the temperature is controlled at 600-650° C. by combustion of organic matter. Decompose organic matter and carbonate, activate kaolinite in diatomite ore, and the ore after roasting for 2 hours is discharged from the lower part of the shaft kiln after being cooled by air. The roasted and cooled material is sent to the vertical mill 5 by the leather conveyor 4, and the crushed powder is sent to the upper powder selector by the exhaust fan 18. In the powder separator, quartz, feldspar, and iron ore are too hard to be finely ground, so the coarser particles are blocked and removed, and the diatomite can be purified. The purified diatomite is separated from gas and solid by a bag dust collector, and the powdery diatomite is fed quantitatively by a screw conveyor 7,...

Abstract

This invention discloses an algicide, it is composed of (by mass percentages): SiO2 65-85%, Al2(SO4)3 and Fe2(SO4)3 being 20-25% respectively. This inventive algicide has double function of combination of chemical flocculation and physical absorption, it can remove blue-green algae and also impurities in water. It has advantages of: easy processing, easy to be used. Low cost, better effect for removing blue-green algae.

Description

technical field [0001] The invention belongs to the technical field of purification, and in particular relates to a product for removing algae and purifying water bodies and a preparation method of the product. Background technique [0002] With the rapid development of my country's economy and the continuous growth of population, the situation of water pollution is becoming more and more serious. In the case of eutrophication of surface water, the complex composition of inorganic and organic matter, and the proliferation of blue-green algae, the problem of water pollution and odor is urgent. [0003] After the 1990s, many inland lakes and rivers in my country were polluted and eutrophic due to urban domestic sewage and industrial wastewater discharge, resulting in a large outbreak of blue-green algae. Dianchi Lake in Kunming, Taihu Lake in Wuxi, and Yanhu Lake in Anhui are particularly prominent, and some even seriously affect the drinking water of urban residents. Over t...
