Meerschaum water purifying agent for quickly purifying marine culture water body

Abstract

The invention discloses a meerschaum water purifying agent for quickly purifying a marine culture water body. The technical scheme is characterized in that the quick marine culture water purifying agent is mainly composed of meerschaum and rice hull. The water purifying agent is prepared through the following steps: performing PICT (pressure-shear induced chemical transitions) pulverization, soaking, stirring, extruding, drying, screening, and packaging to obtain the finished product. In the water purification and filtration process, the specific surface area of meerschaum is increased through a PICT technology, thus removing granular and colloid pollutants through adsorption, and effectively removing harmful substances such as key pollutants ammonia nitrogen, COD (chemical oxygen demand) and the like causing eutrophication of a water body. Big electrostatic attraction power and stress fields are formed outside the kieselguhr modified through the PICT technology, so that the ion-exchange property is enhanced, thereby being more beneficial to adsorptive purification of harmful substances such as Hg<2+>, Pb<2+>, Cr<6+>, Cd<2+>, Cu<2+>, other heavy metal ions and the like in the water. Thus, the meerschaum water purifying agent is applicable to purification and filtration such as quick ammonium reduction, nitrogen, phosphorus and COD removal, heavy metal adsorption and the like in the marine culture process, and is also applicable to purification of a marine aquarium fish water body.

Description

technical field [0001] The invention relates to the field of aquaculture, and in particular relates to a sepiolite water purifier for quickly 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 aquaculture ...

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
