Abstract

The invention discloses a photocatalytic biosorbent and its preparation method and application. The photocatalytic biosorbent includes Prochaeta chrysosporium pellets, graphite type C 3 N 4 and calcium alginate, graphite type C 3 N 4 Calcium alginate is used to coat the hyphae of P. chrysosporium cocci. The preparation method includes: converting graphite type C 3 N 4 The material is added to the sodium alginate solution for ultrasonic dispersion, and then the spore suspension of P. chrysosporium is added and mixed evenly. The resulting mixed solution is added dropwise to the calcium chloride solution to harden. After hardening, the embedded pellet is obtained for shaking culture. A photocatalytic biosorbent was obtained. The photocatalytic biosorbent of the present invention has the advantages of strong photocatalytic ability, high adsorption efficiency, low cost, convenient separation and recovery, etc. It can be used to treat composite wastewater containing cadmium and 2,4,6-trichlorophenol, and can simultaneously remove wastewater The heavy metal cadmium and organic pollutant 2,4,6-trichlorophenol are contained in it, and the adsorption and degradation efficiency is high.

Description

technical field

[0001] The invention belongs to the field of photocatalytic biosorbent materials, and relates to a photocatalytic biosorbent and its preparation method and application, in particular to Phanerochaete chrysosporium and graphite type C 3 N 4 Photocatalytic biosorbents of materials and their preparation methods and applications. Background technique

[0002] At present, methods such as adsorption, coagulation, and biofilm are usually used to treat heavy metal wastewater. These methods are generally favored by people because of their low cost. Phanerochaete chrysosporium among the white-rot fungi has a strong adsorption effect on heavy metals. However, in the complex polluted wastewater containing heavy metals and organic pollutants, the adsorption of Phanerochaete chrysosporium to heavy metals and the degradation of organic pollutants low efficiency. Graphite C 3 N 4 The material is a typical photochemical catalyst, which can catalyze and degrade organic po...
