Abstract
The invention discloses a rotary-type bioreactor, comprising a reaction tank, wherein bacterium solution is filled in the reaction tank; a first water inlet and a first water outlet are formed at the left end of the reaction tank; a second water outlet is formed at the right end of the reaction tank; a drum is arranged in the reaction tank; the drum sinks in the bacterium solution, and the interior of the drum is hollow; a hole is formed on the drum, and the aperture of the hole is less than the aperture of a reaction material; and a backflow tube is arranged in the drum; and a hole is formed on the backflow tube. Via the mode aforementioned, the rotary-type bioreactor adopting the scheme has the advantages of being less in pollution, temperate in working condition, short in flow, low in cost, less in investment and the like, and has the characteristic of being wide in mineral applicability in case of being applied to mining metallurgical engineering; oxygen is provided for the bacterium solution via the rotation of the drum so as to directly culture the bacterium solution, and the operation is convenient and fast; the rotary-type reactor performs reaction by means of injecting the bacterium solution, thus avoiding the damages of a shearing force in the normally-used stirring mode on the cells of bacteria, and contributing to the survival of the bacteria; and the reaction of the rotary-type reactor during a rotation process is uniform.
Description
Technical field
The present invention relates to process the old circuit board technical field, particularly relate to a kind of rotary bio-reactor that carries out committed step with microorganism.
Background technology
At present, be divided into following a few class for the treatment of the method for old wiring board (be called for short PCB): pyrometallurgy, hydrometallurgy, mechanical sorting facture, or by above-mentioned several method combination treatment.Pyrometallurgy and hydrometallurgy are mainly used in the recovery of the precious metals such as gold and silver, and its technique is simple, but cost is high, and secondary pollution is serious.The prerequisite of mechanical sorting facture is the separated necessary monomer dissociation of material, the method that reaches monomer dissociation is normally broken, in abandoned printed circuit board metal and nonmetal between combine by the technique such as film, by suitable equipment and breaking method, can make metal and nonmetal monomer dissociation.But wherein be that mode with alloy, coating or welding combines between the various metals, be difficult to make the metal monomer dissociation with Mechanical Crushing, so the mechanical sorting facture can only be used with other method as supplementary means.Above-mentioned several old wiring board facture is destructive strong, and technical process is complicated, causes cost of investment high, and use range also has limitation.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of rotary bio-reactor, comprise a reactive tank, bacterium liquid is housed in the reactive tank, the left end of reactive tank is provided with the first water-in and the first water outlet, the right-hand member of reactive tank is provided with the second water outlet, be provided with cylinder in the reactive tank, cylinder submerges in the bacterium liquid, the cylinder inner hollow, cylinder is provided with the hole, the aperture in hole is less than the reaction mass aperture, and cylinder inside is provided with a return line, and return line is provided with the hole.
Further, be provided with baffle plate in the reactive tank, prevent the material leakage, flow with bacterium liquid.
Further, cylinder is provided with 2.
The invention has the beneficial effects as follows: have pollution less, gentle, the advantages such as flow process is short, cost is low, less investment of working conditions, and have the wide characteristics of mineral suitability in the application of mining metallurgical engineering, in the middle of the recovery in the unmanageable complicated ore of conventional art, low taste table Tu Kuang, discarded ore deposit etc., have unique advantage; The bacterium liquid that rotates to be by cylinder provides oxygen directly to cultivate bacterium liquid, and is convenient and swift; Rotary reactor reacts by the mode that bacterium liquid is injected, and has avoided the shearing force of common used alr mode to the damage that bacterial cell causes, and is conducive to the survival of bacterium; Rotary reactor rotation process reaction evenly can not cause soon Cu2+ concentration to raise because of certain partial reaction, thereby bacterium is exerted an influence; Rotary reactor easy accessibility is conducive to load the PCB powder, also convenient taking-up after reaction is finished.
