Water quality purifier special for aquaculture

Abstract

The invention discloses a water quality purifier special for aquaculture. The water quality purifier special for the aquaculture comprises the following raw materials in part by weight: 30 to 36 parts of rare earth-modified zeolite, 18 to 22 parts of bamboo charcoal particle and 10 to 15 parts of tourmaline, wherein the rare earth-modified zeolite is prepared by the following steps: dissolving lanthanum chloride and cerous chloride in water in part by weight; after stirring the solution to be uniform, adjusting the pH value to be 10 to 11; adding crushed zeolite into the solution; after soaking the crushed zeolite for 15 hours, filtering and washing the zeolite with water to be neutral; drying the zeolite; baking the dried zeolite at the temperature of 500 DEG C for 4 hours to obtain the rare earth-modified zeolite, wherein when the zeolite is modified, the lanthanum chloride, the cerous chloride and the zeolite are in the weight ratio of 1 to 2 to 12. The finished product, namely, the water quality purifier special for the aquaculture, has a good effect on purifying the water quality, so that the concentration of ammonia nitrogen and nitrite in a water body is reduced obviously, the concentration can be reduced by 88 percent to the maximum, the COD (chemical oxygen demand) is reduced obviously, and the effect is remarkable; the water quality purifier special for the aquaculture is environment-friendly, and cannot cause secondary pollution of the water body.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a special water purifier for aquaculture. Background technique [0002] my country is a large aquaculture country. In recent years, my country's aquaculture industry has developed rapidly, and environmental problems such as water quality deterioration caused by aquaculture have become increasingly serious. At present, the water quality control of aquaculture mainly includes physical, chemical and biological methods. Physical methods can only remove suspended solids in water, and it is difficult to remove dissolved pollutants. Both chemical and biological methods will cause secondary pollution of water quality. Therefore, the development of Efficient, environmentally friendly, and stable water quality purifiers are technical problems to be solved urgently. [0003] At present, there have been many reports on the use of modified zeolite to purify water...

Problems solved by technology

At present, the water quality control of aquaculture mainly includes physical, chemical and biological methods. Physical methods can only remove suspended solids in water, and it is difficult to remove dissolved pollutants. Both chemical and biological methods will cause secondary pollution of water quality. Therefore, the development of Efficient, environmentally friendly, and stable water quality purifiers are technical problems to be solved urgently

[0003] At present, there have been many reports on the use of modified zeolite to purify water quality. It is mainly modified by acid, alkali and organic modifiers to improve the adsorption and purification performance of zeolite. Further improve
