Photosynthetic bacteria immobilization compound and photosynthetic bacteria adsorption material

Abstract

The invention provides a photosynthetic bacteria immobilization compound and a photosynthetic bacteria adsorption material. The photosynthetic bacteria immobilization compound comprises photosyntheticbacteria, 2-3parts of alginate gel by mass and 3-5 parts of iron-rich clay by mass, and 6-24000 million of the photosynthetic bacteria are contained in per cubic centimeter of the photosynthetic bacteria immobilization compound. According to the photosynthetic bacteria immobilization compound, an iron-rich clay three-dimensional structure as a skeleton is coated with and / or filled with the alginate gel, so that a plurality of micro spaces are formed, and the photosynthetic bacteria are contained or enclosed into the micro spaces. The adsorption material contains a layered porous component andthe photosynthetic bacteria immobilization compound which is arranged or bonded on the layered porous component. The photosynthetic bacteria immobilization compound is reasonable in design, convenient to use, high in immobilization density, high in rigidity and high in heavy metal treatment efficiency; the adsorption material is convenient and efficient to use.

Description

technical field [0001] The invention relates to the technical field of microorganisms, and more specifically relates to a photosynthetic bacteria immobilized substance and a photosynthetic bacteria adsorption material, and is especially suitable for the recovery and treatment of high-priced metal chromium. Background technique [0002] Heavy metal pollution is a serious problem. Once heavy metals enter the environment, they will not decompose in the environment like organic pollutants, but may last for a long time. Although there are changes in chemical forms, many of them are irreversible processes, so they cannot be eliminated from the environment, but will remain in the environment for a long time. Heavy metals that enter the human body through various channels will not be decomposed in the body. Therefore, the environmental pollution of heavy metals has aroused great concern. For example, the heavy metal element chromium is one of the main sources of heavy metal pollu...

The main disadvantage of this type of method is that it is expensive when treating low-concentration wastewater

Therefore, the above two methods of thinking are not suitable for large-scale promotion
