Problems solved by technology

[0005] The existing biochar carrier is made of biochar adsorbed with microorganisms into bacterial balls, which is cumbersome to operate and high in cost; in the actual application process, the external packaging material of the bacterial agent is likely to hinder the contact between the bacterial strain and the pollutants, reducing the concentration of the bacterial agent.

Embodiment 1

[0034] The ramie stalk is dried at 80°C, broken into powder, and 100 mesh particles are screened out for use, and ammonium bicarbonate, calcium magnesium phosphate fertilizer and 85wt% phosphoric acid are configured into a total mass fraction of 3g:1g:25ml with water 50wt% mixed solution, take ramie stalk powder and mixed solution in a crucible according to 1g:20ml, stir evenly, put it in an oven at 50°C for 40 minutes, raise the temperature to 200°C and burn for 5 hours to obtain rich charged Precursors for functional groups and rich void structures. Take out the precursor, first use 15wt% HCl solution to sonicate for about 5 minutes to wash away the carbonate precipitation and expose the gaps; then soak in 15wt% NaOH for 3 hours, and sonicate for about 20 minutes to fully wash away the acidity and impurities inside the three-dimensional biochar, and then use Ultrasonic washing with distilled water until the pH is 7.5 to obtain the finished product "honeycomb structure biocha...

Abstract

The invention discloses biochar suitable for loading photosynthetic bacteria system rhodopseudomonas and a preparation method and application thereof. The preparation method includes the steps that biomass raw materials, ammonium bicarbonate, calcium magnesium phosphate fertilizer and phosphoric acid are mixed, swelling permeation is conducted at the temperature of 40-70 DEG C, and then carbonization is conducted at the temperature of 150-350 DEG C so that the biochar is obtained. The honeycomb structure biochar prepared by the invention is rich in charged functional groups such as hydroxyl, carboxyl, quinonyl and the like, rich in N, O and P elements, rich in pore structures and better in mechanical strength, provides an appropriate living environment for bacilus rhodopseudomonas with thewidth of 0.5-0.9 [mu]m and the length of 1.2-2.0 [mu]m, and the bacilus rhodopseudomonas can be used for repairing black and odorous water, removing organic pollutants in the water, removing nitrogenand phosphorus and restoring the self-purification capacity of the water.

Description

technical field [0001] The invention belongs to the technical field of biochar preparation and environmental protection, and relates to a biochar suitable for carrying photosynthetic bacteria Rhodopseudomonas, a preparation method thereof and an application in purifying black and odorous water. Background technique [0002] Immobilized microbial remediation is a type of microbial remediation, which uses physical or chemical methods to fix free microorganisms in an area and maintain a high degree of enrichment and activity to meet the application of biotechnology. The choice of carrier material is very important in this key technology. Although natural polymer carrier materials such as alginate, agar, carrageenan, gelatin, and sponge have no biological toxicity and good mass transfer performance, their physical strength is low. Synthetic polymeric support materials usually have greater physical strength, but their mass transfer properties are poor. It is urgent to develop ne...
