Abstract

The invention relates to a bench-scale device of a water supply pipe network microbiological test. The device mainly comprises a water tank (28), a water inlet main pipe (30), a water outlet main pipe (29), a branch pipe a (25), a branch pipe b (26) and a branch pipe c (27), wherein the water tank (28) is connected with the water inlet main pipe (30) in series; two ends of each of the branch pipe a (25), the branch pipe b (26) and the branch pipe c (27) are connected with the water inlet main pipe (30) and the water outlet main pipe (29) in parallel. Compared with the prior art, the device disclosed by the invention can be used for realizing comprehensive study on micro-organisms in pipe wall and pipe network water under the conditions of different raw water, different pipe materials, different hydraulic conditions, different water ages, different disinfectants and the like.

Description

technical field [0001] The invention belongs to the technical field of municipal water supply pipe network, and relates to a small test device for microorganism test of water supply pipe network. Background technique [0002] As the most important link in the entire water supply system, the water supply network plays a key role in water quality safety. Since bacterial growth was found in the water supply network using chlorine disinfection in the late 1930s, the re-growth of microorganisms in the water supply network and the secondary pollution caused by it have received more and more attention. The microorganisms in the water supply pipe network are mainly reproduced in the form of attaching to the pipe wall to grow and form a biofilm. Some microorganisms in the water source water survived after being treated by the water treatment process and entered the pipe network system. The dissolved trace organic matter in the water These microorganisms can be repaired and regrown i...
