Abstract

The invention provides a hydraulic stirring device and method for preparing immobilized microorganisms. The hydraulic stirring device comprises a rack, wherein a control panel and a time relay are arranged at the upper part of the rack, a machine table is arranged at the lower part of the rack, a stirring mechanism and a pressing mechanism are arranged on the control panel at an interval, a material cylinder is arranged on the machine table, the material cylinder is conveyed to the corresponding position between the stirring mechanism and the pressing mechanism through a conveying plate in a reciprocating manner, a material disc is arranged in the machine table to contain materials extruded from the material cylinder, the material disc is conveyed through a conveying shaft, and the time relay controls the running speeds of the pressing mechanism and the conveying shaft simultaneously. The problem of how to automatically control uniform stirring and extrusion forming of materials is solved, the embedment technology is further simplified, the high-yield processing requirement is met, and the product quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to an integrated stirring hydraulic device suitable for preparing immobilized microorganisms. Background technique [0002] In order to deal with the increasingly serious pollution problem, scientists from all over the world are trying to find water treatment technologies with low cost, low energy consumption and low secondary pollution. Among them, due to the unique role of microorganisms in removing pollutants, biodegradation is regarded as a relatively effective, economical and energy-saving water treatment technology. [0003] At present, when the existing traditional microbial technology treats sewage, it usually directly inoculates microorganisms in the sewage to be treated, and reduces the concentration of pollutants through the growth, absorption and metabolism of microorganisms. However, due to environmental factors, competition, easy loss and other reasons, ...
