Nano-biological water body remediation agent for aquaculture and preparation method thereof

Abstract

The invention discloses a nano-biological water body remediation agent for aquaculture and a preparation method thereof. The nano-biological water body remediation agent comprises a carrier and complex bacteria attached to the carrier, wherein the carrier comprises the following ingredients in percentage by weight: 10-70 wt% of nano tourmaline, 10-70 wt% of nano titanium dioxide, 10-70 wt% of modified zeolite and 10-50 wt% of montmorillonite, and the complex bacteria comprise photosynthetic bacteria, denitrifying bacteria, nitrifying bacteria and phosphorus accumulating bacteria. The nano-biological water body remediation agent for aquaculture, disclosed by the invention, is economical and environment-friendly and is simple and convenient to prepare; the adsorption characteristics of the natural mineral materials are cooperated with the degradation characteristics of the microorganisms, so that organics in a water body can be efficiently adsorbed and degraded, and the remediation efficiency of water quality is higher; and the microorganisms can increase the dissolved oxygen in the water body while harmful substances, such as ammonia nitrogen and hydrogen sulfide, are efficiently decomposed, excellent-quality baits can be supplied to aquatic livestock through the propagation of the microorganisms, and the secondary pollution on the water body cannot be caused.

Description

technical field [0001] The invention relates to the technical field of water body restoration, in particular to an aquaculture nanobiological water body restoration agent and a preparation method thereof. Background technique [0002] Traditional aquaculture water quality control methods mainly include physical methods, chemical methods and biological methods. However, in production applications, these methods have been found to have disadvantages such as cumbersome operations and low water purification efficiency. Therefore, finding an economical, efficient and simple water treatment technology is the development direction of water quality control in the future. [0003] Currently more economical and effective water purification technology has ozone water treatment technology: ozone (O 3 ) can diffuse into the cell by destroying and decomposing the cell wall (membrane) of bacteria, and oxidize and destroy the enzyme in the cell to quickly kill the pathogenic bacteria; it c...

AI Technical Summary

Problems solved by technology

In most cases, the natural conditions of aquaculture water cannot fully meet the requirements of bioremediation, and the efficiency and speed of natural bioremediation are too low. Adding exogenous microorganisms is an important way to optimize the micro-ecosystem. On the one hand, it can regulate the micro-ecosystem. The interaction of microbial populations and communities, on the other hand, can increase the concentration of microorganisms and their metabolic activities in the microecosystem

However, there are also major limitations. Under normal circumstances, the microorganisms introduced into the system are scattered in the water body, "dwelling without a fixed place", and the stability of the community is not high, so it is difficult to compete with the indigenous microorganisms to become the dominant species.
