Abstract

The invention relates to a device and a technology for preparing engineering embedding fixing microorganism spheric bodies. Embedding medium solution in an embedding medium kettle is added into a mixing kettle, and a sorption agent in a sorption agent organism kettle and microorganism solution are added into the mixing kettle. After fully mixed, the two solutions enter a shunting head by an isolating valve and then are sprayed into a cross linker kettle. After solidifying and cross linking, spheric grains which are the microorganism embedding spheric bodies are obtained. The invention overcomes the defect that large-scale mass production can not carried out by the prior embedding fixing microorganism technology, divides liquid which continuously flows in a pipeline connected in front of the valve by the isolating valve so as to discontinuously provide feed liquid for the shunting head, and further shunts the feed liquid provided by the isolating valve by the shunting action of the shunting head so as to ensure that miscible liquid from the mixing kettle enters cross linker solution in a spraying mode to form precipitation of solid spheric grains. The invention realizes the mass production of microorganism embedding solid globes having good stability by the embedding fixing technology.

Description

technical field

[0001] The invention relates to the technical field of repairing polluted water environment by using microbial degradation, in particular to a device and process for engineered embedding and fixing microbial spheres. Background technique

[0002] Water environmental pollution such as surface water and groundwater has become a hot issue that the world pays attention to. In the traditional biological treatment process of polluted water, microorganisms usually grow in suspension in water, so they are easily lost from the reactor. In addition, the density difference between microorganisms and water is small, and it is difficult to recover microorganisms from the water flowing out of the reactor for reuse. The development of microorganism immobilization technology provides a new way to solve this problem.

[0003] Microbial immobilization technology is a new technology developed in the 1970s. It uses biological or chemical polymer materials to embed microorganism...
