Problems solved by technology

Biological treatment technology also has certain negative effects. For example, although algae can absorb part of ammonia nitrogen, they cannot load the ammonia nitrogen produced by high-density cultivation; Lose the purifying effect of algae on water quality, even the algae cells die, releasing cell substances and deteriorating water quality
The biological filter bed has a good effect on removing ammonia nitrogen, but the nitrate nitrogen generated by the conversion of ammonia nitrogen remains in the pool water, and the discharge of wastewater containing high nitrate nitrogen into the environment will cause secondary pollution

Embodiment 1

[0039] (1) Zeolite modification

[0040] Pour the natural zeolite block into a jaw crusher for crushing, then further grind it with a disc mill, and sieve it with a vibrating sieve to obtain zeolite with different particle sizes, and finally pass it through an 80-mesh sieve for later use. Weigh a certain amount of zeolite passing through an 80-mesh sieve, put it into an oven, and calcine it at a temperature of 250° C. After 5 hours, take it out and put it in a desiccator to cool to room temperature, and seal it for future use.

[0041] (2) Calcination of dolomite

[0042] Pour the natural dolomite minerals into the jaw crusher for crushing, then calcinate at 1600°C for 5 hours to form calcined dolomite, then further grind it with a disc mill, and sieve it with a vibrating sieve to obtain dolomite with different particle sizes, passing through 80 mesh Sift for later use.

[0048] (1) Zeolite modification

[0049] Pour the natural zeolite block into a jaw crusher for crushing, then further grind it with a disc mill, and sieve it with a vibrating sieve to obtain zeolite with different particle sizes, and finally pass through a 2000-mesh sieve for later use. Weigh a certain amount of zeolite passing through a 2000-mesh sieve, put it into an oven, and calcine it at a temperature of 800 ° C. After 2 hours, take it out and put it in a desiccator to cool to room temperature, and seal it for future use.

[0050] (2) Calcination of dolomite

[0051] Pour natural dolomite minerals into a jaw crusher for crushing, then calcinate at 700°C for 1.5 hours to form calcined dolomite, then use a disc mill to further grind it, and sieve it with a vibrating sieve to obtain dolomite with different particle sizes. After the mesh sieve, it is ready for use.

[0057] (1) Zeolite modification

[0058] Pour the natural zeolite block into a jaw crusher for crushing, then further grind it with a disc mill, and sieve it with a vibrating sieve to obtain zeolite with different particle sizes, and finally pass it through a 1800-mesh sieve for later use. Prepare a hydrochloric acid solution with a concentration of 20 mol / L at room temperature, weigh a certain mass of 1800-mesh zeolite with a liquid-solid ratio of 3:1, soak it in the prepared 20 mol / L hydrochloric acid solution and stir it at a constant speed for 1 h, After standing for 5 hours, filter, wash, dry, and place in a desiccator for later use.

[0059] (2) Calcination of dolomite

[0060] Pour natural dolomite minerals into a jaw crusher for crushing, then calcinate at 800°C for 4.5 hours to form calcined dolomite, then use a disc mill to further grind, sieve with a vibrating sieve to obtain dolomite with different particle sizes, pass 1800 After the mesh sieve, it is ready for u...

Abstract

The invention discloses an aquaculture water purifying agent, which consists of modified zeolite, calcined dolomite and tourmaline particles as raw materials, wherein the weight percentage of the modified zeolite is 10 to 70 percent; the weight percentage of the calcined dolomite is 10 to 70 percent; the weight percentage of the tourmaline particles is 10 to 50 percent. The invention also discloses a method for preparing the aquaculture water purifying agent. All the raw materials used in the invention are environmental mineral materials and cannot cause secondary pollution. The purifying agent has the advantages of active regulatory effect on micro-ecosystems in aquaculture water, as well as good economic and social benefit.

Description

technical field [0001] The invention relates to a water quality regulator, in particular to a water quality purifier for aquaculture water quality regulation prepared from modified zeolite, calcined dolomite and tourmaline particles as raw materials. Background technique [0002] The water quality control techniques for aquaculture mainly include physical, chemical and biological methods. [0003] The physical method is based on the physical and chemical properties of the water body and the pollutants in the water body, using mechanical methods to purify the water quality, including natural precipitation, physical filtration and other methods. These methods are simple in principle and widely used, mainly to remove colloidal and suspended impurities in wastewater. Dissolved pollutants in wastewater are difficult to remove. [0004] Chemical method is to remove pollutants in wastewater or transform them into other substances through some chemical reactions, so as to turn harm...
