| titleOfInvention | A kind of preparation method of sewage treatment microorganism carrier |
| abstract | The invention relates to the technical field of sewage treatment, in particular to a method for preparing a microorganism carrier for sewage treatment, which includes molding, cross-linking, modification and reconstitution; since the acidic reagent participating in the reaction during the chemical cross-linking process will remain in the finished product and affect the microorganisms At the same time, the hardening time of the carrier is long, and it is easy to cause adhesion. In the finished product prepared by the physical cross-linking method, the carrier material is directly prepared by mixing microorganisms with a neutral polymer solution and using cyclic cooling. Its porosity is high and its water content is large, which avoids the influence on the activity of microorganisms, but its large water solubility will cause poor stability; The vinyl alcohol resin is modified, and the temperature adjustment operation in the process of cyclic heating and cooling can improve the bearing performance of the finished product morphological structure for microorganisms, thereby improving the application effect of the preparation method of the microbial carrier for sewage treatment. |
