A kind of medical stone water purifying agent for quickly purifying mariculture water

Abstract

The invention discloses a medical stone water purifier quickly purifying a marine culture water body, which is mainly characterized in that the quick marine culture water purifier mainly comprises medical stone and rice hulls. A finish product is formed by micro-cutting assisted grinding, soaking, stirring, extruding, drying, screening and packaging. In a water purification and filtration process, the specific surface area of the medical stone is increased by a micro-cutting assisted technology, granular and colloid pollutants are absorbed and removed, and harmful substances, such as principal pollutants of water body eutrophication (ammonia nitrogen, nitrite nitrogen and H2S) can be effectively removed. Since a greater electrostatic attraction force and a stress field are formed outside the medical stone modified by the micro-cutting assisted technology, the ion-exchange property is improved, and the adsorption purification of the harmful substances such as heavy metal ions (such as Hg<2+>, Pb<2+>, Cr<6+>, Cd<2+> and Cu<2+>) in water is more facilitated. The purifier is applicable to the purification and filtration such as quick ammonia reduction, as well as nitrogen, nitrite nitrogen and H2S removal in the marine culture process, and also applicable to purifying a marine aquarium fish water body.

Description

technical field [0001] The invention relates to the field of aquaculture, and in particular relates to a medical stone water purifier for rapidly purifying seawater aquaculture water. Background technique [0002] Seawater is the basic environmental condition for the survival of seawater animals. As the saying goes: "Three points for fish, seven points for water". The quality of water quality directly affects their growth status and the economic benefits of farmers. With the development of economy and science, people's demand for aquatic products is increasing day by day. In the case that the catch cannot meet the market demand, the aquaculture industry has transformed from the traditional extensive management and resource-dependent aquaculture to the current intensive one. Breeding methods. However, with the rapid development of high-density and high-intensity artificial breeding and the increasing pollution of the breeding environment, the degree of pollution of aquacult...

Problems solved by technology

However, there are generally disadvantages of time-consuming, laborious, high energy consumption and high cost; although chemical water purifiers can quickly react and transform harmful substances for sudden water body deterioration, they will cause secondary pollution to the water body environment; microecological preparations are environmentally friendly and clean Water solution, but there are disadvantages such as long activation time of flora, poor adaptability to survival and reproduction, and reduced number
