Comprehensive pipeline disinfection effect testing apparatus

Abstract

A comprehensive pipeline disinfection effect testing apparatus belongs to the field of building water supply and drainage, and is an experimental teaching apparatus which simulates a water supply pipeline system in a building and tests the pipeline disinfection effect and the condition of the sediments on the inner walls of pipelines. The comprehensive pipeline disinfection effect testing apparatus comprises a disinfector system, a pressure supply system, a pipe network and pipeline sampling observation system and a data acquisition system. The disinfector system comprises a chlorine dioxide generator (1) and an ultraviolet disinfector (2), and can provide the function of chemical disinfection and / or physical disinfection; the pressure supply system comprises a low-pressure pump (4), a high-pressure pump (5) and an operation cabinet (6), and provides needed pressure; the pipe network and pipeline sampling observation system respectively comprises a set of galvanized steel pipeline (7), a set of UPVC (unplasticized polyvinyl chloride) pipeline (8), sampling ports (13) and two observation windows (11), the two sets of pipelines can operate independently or in series, water samples in the pipelines can be collected from the sampling ports, and the sediments on the inner walls of the pipelines can be observed and sampled via the observation windows; and the data acquisition systemcomprises a paperless recorder (14), and records the amount of residual chlorine, flow and pressure. The apparatus has the characteristics of small floor occupation, multiple functions, no pollution,stable operation, flexibility and the like.

Description

technical field [0001] The utility model relates to a comprehensive testing device for pipeline disinfection effect, which belongs to the field of building water supply and drainage, and relates to an experimental teaching device for testing the persistence of disinfection effect, the change rule of disinfectant residual, and the analysis of the sediment condition on the inner wall of the pipeline by using simulated water supply pipelines inside buildings. Background technique [0002] The comprehensive testing equipment for pipeline disinfection effect is an important experimental teaching device for testing the change of disinfection effect with residence time in the disinfected water body in the building water supply system and the deposition of inorganic or organic matter on the inner wall of water supply pipelines of different materials with operation time. [0003] With the rapid development of science and technology and social economy, and the improvement of people's h...

Problems solved by technology

[0004] At present, there is no experimental teaching device at home and abroad for testing the persistence of the disinfection effect of the building water supply system and the reproduction of microorganisms. The reason for this phenomenon is the lack of a set that can simulate and continuously take samples to detect the disinfection in the actual building water supply pipeline. The experimental device that accurately collects the experimental data of the change of the residual dose and the number of microbial reproduction
