Abstract

The invention discloses a method for flocculation processing after adsorption of polluting positive ion by microorganism. According to the method, a flocculating agent is adopted for processing, after proper regulation of the flocculating conditions, suspending microorganism thallus adsorbing the polluted positive ions such as heavy metals and radionuclide are rapidly separated from a liquid phase through flocculation and then collected, the microorganism thallus can be flocculated in shorter time, the whole flocculation process is simple and practical, low in required cost, applicable to large scale processing of polluting positive ions in waste water of heavy metal pollution industry, nuclear industry or the like, and also applicable to sudden water body pollution accidents, and has a wide development space and market prospect.

Description

technical field [0001] The invention relates to a method for using a flocculant to flocculate microorganisms after absorbing polluting cations such as heavy metals and nuclide ions, and belongs to the technical field of sewage treatment. Background technique [0002] At present, the use of microorganisms to adsorb heavy metal ions in wastewater treatment has attracted increasing attention. Based on the related research on the use of microorganisms to adsorb heavy metal ions, microorganisms are used to treat radioactive waste, especially the radionuclide ions in the liquid phase environment. The research on adsorption treatment is attracting people's attention day by day. This is a new supplement and exploration to the existing nuclide solidification method, and it also has great application prospects. [0003] Biosorption (Biosorption) is an emerging technology for treating heavy metal ion wastewater pollution. It adsorbs heavy metal ions through biological cells (mainly mic...
