Water supply pipeline biological membrane sampler and method thereof

Abstract

The invention discloses a water supply pipeline biological membrane sampler and a method thereof. The water supply pipeline biological membrane sampler comprises a sampling piece, a sampling rod, a rubber pad, a sampler base and a sampler fixing ring, wherein the sampler base is arranged on the sampler fixing ring; a thread is arranged on the sampling rod; a thread hole matched with the sampling rod is formed in the sampler base; a thread is formed at one end of the sampling piece; a thread hole matched with the sampling piece is formed in the end part of the sampling rod; the rubber pad is sleeved on the sampling rod. The water supply pipeline biological membrane sampler can sample a pipeline biological membrane under a condition that the working condition is not affected; complicated and expensive operations can be avoided; the sampling pieces which are made of different materials and have different sizes can be arranged according to specific situations such as a pipe material of a pipeline to be measured, the pipe diameter of the pipeline, a hydraulic condition and a monitoring index; the biological membrane obtained by the sampler is representative, and the reliability of experiment data is guaranteed. The water supply pipeline biological membrane sampler is simple in structure and convenient to operate and popularize.

Description

technical field [0001] The invention relates to the technical field of drinking water biological sampling equipment, in particular to a water supply pipeline biofilm sampler and a method thereof. Background technique [0002] With the rapid development of social economy and the continuous acceleration of urbanization, the safety of drinking water has aroused widespread concern. In all aspects of water supply (including water source, water plant, etc.), the water supply pipe network is the weakest link: even if the water source water quality is good, the water plant factory water compliance rate is close to 100%, but due to the scale and biofilm in the pipe network Existence, when hydraulic conditions change or operational emergencies occur, it will lead to the shedding of biofilm, thus affecting the water quality of tap water. In the process of water supply, when the number of microorganisms in the water reaches a certain amount, they will be adsorbed on the pipe wall to fo...

AI Technical Summary

Problems solved by technology

The only way to sample the biofilm in the actual pipeline is to cut off a specific pipe section and sample and analyze the biofilm in the pipe section. However, this method must intercept the actual pipeline, which is difficult to operate, expensive, and difficult to popularize.
