Pipe wall biofilm growth simulation reactor

Abstract

The invention relates to a pipe wall biofilm growth simulation reactor, which comprises a water inlet pipe, a water outlet pipe and reactor bodies. The water inlet pipe and the water outlet pipe are connected by a plurality of reactor bodies in series connection. Each reactor body is composed of water pipe sections, threaded caps and fillers. Both ends of the water pipes are provided with dismountable threaded ports, and are connected to the threaded caps through the threaded ports. The fillers are disposed in the water pipes. Water enters from the water inlet pipe, penetrates each reactor body in order, and flows out from the water outlet pipe. The fillers in the water pipe sections are taken out, the biofilms on the fillers are collected, and a water sample is collected at the water outlet pipe to perform analysis. Compared with the prior art, the pipe wall biofilm growth simulation reactor provided by the invention truly simulates the hydraulic conditions and nutritional status of actual pipes, at the same time increases the biofilm attachment area, so that operation of the biofilm collection process can be simple, and no destructive effect is generated to the pipe walls.

Description

technical field [0001] The invention relates to a simulated reactor, in particular to a simulated reactor for the growth of pipe wall biofilm. Background technique [0002] At present, there are two designs of known water supply pipeline simulation systems: non-circulatory design and circular design. The non-circulatory design system is essentially a plug-flow reactor, and the biodegradable organic matter is continuously consumed by microorganisms as the pipeline distance increases. The cycle design system can be idealized as complete mixing inside the continuous stirring reactor system, and the effluent water quality is basically the same as the internal water quality conditions of the system. However, the surface area for the biofilm to attach to the two pipeline simulated reactors is small, and it is inconvenient to sample the biofilm on the wall of the non-circulatory simulated pipeline. At the same time, the sampling process is destructive to the tube wall, which is no...

However, the surface area for the biofilm to attach to the two pipeline simulated reactors is small, and it is inconvenient to sample the biofilm on the wall of the non-circulatory simulated pipeline. At the same time, the sampling process is destructive to the tube wall, which is not conducive to the long-term continuous and stable operation of the simulated system.

However, the hydraulic conditions and nutrient status of the water body in the circulation simulation pipeline are quite different from the actual pipeline conditions, and the reference is less
