Embodiment Construction

[0038] Embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0039]

[0040] FIG. 1 is a block diagram showing main parts of a water treatment system according to a first embodiment of the present invention.

[0041] The system has a grit chamber 1 that pumps raw water through an inlet (not shown) guided by a water pipe, and a grit chamber 2 that temporarily stores the raw water supplied from the grit chamber 1 . The pool 2 is used to adjust the amount of raw water supplied to the water purification process.

[0042] The system also has a coagulation / sedimentation tank 3 to guide the raw water supplied by the tank 2 through the pre-treatment process. During the pre-treatment process, the raw water flow meter 4 and the first ultraviolet radiation device (hereinafter also referred to as the pre-ultraviolet radiation device) 5 are arranged on the pipeline for supplying the raw water from the pool 2 to the coa...

Abstract

A water treatment system for water purification treatment using ultraviolet radiation, the system comprising: a pre-ultraviolet radiation device (5) for emitting ultraviolet light in the early stage of the water purification process, and a post-ultraviolet radiation device (5) for emitting ultraviolet light in the later process device (10), and a controller (14) for controlling these ultraviolet radiation devices.

Description

[0001] This application is a divisional application of the invention patent application with the application number "200610071878.X" and the invention name "ultraviolet radiation water treatment system" submitted by the applicant on March 29, 2006. Background of the invention [0002] The invention relates to an ultraviolet radiation water treatment system for water purification treatment by ultraviolet radiation. [0003] Traditionally, water systems operating on the basis of chlorine gas sterilization to ensure hygiene represent water treatment systems. [0004] However, in recent years, incidents of water system pollution caused by emerging or re-emerging pathogenic microorganisms such as Cryptosporidium and Giardia have occurred. [0005] Also, algae blooms due to eutrophication of water sources in water systems such as lakes, dams, and rivers, and increased pollution such as organic matter, causing abnormal odor and taste, abnormal color, aggregation and sedimentation inh...
