Simultaneous denitrification and desulfurization-S0 recovery of wastewater in trickling filters by bioaugmentation intervention based on avoiding collapse critical points.

The invention discloses a method for promoting biological column leaching of poor chalcocite, particularly discloses a method for synergistically promoting biological column leaching of the poor chalcocite based on foreign intervention of compound sulfur oxidizing bacteria and the pyrite, and belongs to the technical field of bioengineering. 9K-chalcocite composite medium is used as a leaching solution, by adding a certain proportion of the pyrite and introducing a foreign compound sulfur oxidizing bacteria, various biochemical reactions in the leaching process are controlled, iron and sulfurmetabolism are promoted in the leaching process, and formation of an iron/sulfur passivation film is reduced; and the biological effect in the leaching process is strengthened by adding the compound sulfur oxidizing bacteria in batches, so as to make the copper ions leaching rate increase by 33.9%. The method is easy and convenient to operate, economical and reasonable, and is suitable for large-scale application of similar bioleaching processes.

Method for promoting biological column leaching of poor chalcocite

The invention discloses a method for synchronous desulfurization and denitrification treatment of wastewater based on a bio-trickling reactor, belonging to the field of bioengineering. According to the method, the removal rates of nitrogen and sulfur can reach 80% or above at the same time through arrangement of fillers and mutual cooperation of parameters. Moreover, the method provided by the invention can solve the problems of high operation cost, heavy pollution, high energy consumption and the like in treatment of wastewater containing nitrogen and sulfur in the prior art, and can recoverelemental sulfur to realize resource utilization of wastes.
