Abstract
The invention discloses a bioleaching-method treatment device for easy-to-degrade fibrous protein sludge and belongs to the field of sludge treatment. The bioleaching-method treatment device for the easy-to-degrade fibrous protein sludge comprises a reactor, wherein an outer bottom end of the reactor is fixedly connected with a bottom frame; the bottom frame is connected with a motor; a second through hole is dug at the center of the bottom end of the reactor; a stirring mechanism is arranged at the inner side of the reactor; the stirring mechanism comprises a main stirring rod and a pluralityof secondary stirring rods; the lower end of the main stirring rod penetrates through the second through hole and is clamped with a power output end of the motor; a precipitation mechanism is arranged at the inner side of the reactor. The device disclosed by the invention can be used for extracting extracellular polymeric substances (EPS) secreted by bioleaching microorganisms and the dehydrationrate of the sludge is improved to the greatest extent; meanwhile, fibrous protein and the extracted extracellular polymeric substances (EPS) are combined by utilizing the characteristics of easinessfor degradation and good biocompatibility of the fibrous protein, and then react in a sludge cake, so that the fertility and quality of the sludge cake are improved.
Description
technical field [0001] The invention relates to the field of sludge treatment, in particular to an easily degradable fibrous protein sludge biological leaching treatment device. Background technique [0002] Bioleaching technology is a technology derived from microorganisms. Sludge bioleaching technology is to inoculate complex microorganisms in sludge (about 97% water content), add a small amount of nutrients during operation, and aerate for about 48 hours. , to reduce the pH of the sludge to 2-5 (depending on whether to remove heavy metals), to complete the biological treatment process of deodorization, killing pathogenic bacteria, removing heavy metals and greatly improving the dehydration of sludge. Bioleaching technology has been proved to be a biological method that can not only improve the dewatering performance of sludge but also remove heavy metals, and it is expected to turn sludge into treasure. [0003] Compared with traditional sludge treatment technologies suc...
