Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0024] Such as figure 1 , 2 , As shown in 3, UV radiation device and multi-point ozone dosing device are installed on frame 1. Described UV radiation device comprises flow type ultraviolet ray 3, is vertical structure, and its internal structure is as Figure 5 shown. There is a stainless steel casing 22 with an inner wall finely polished (≤0.5 μm), and a quartz glass sleeve 23 is arranged inside the stainless steel casing 22, and the quartz glass sleeve 23 and the outer cover (upper and lower) 29 of the UV radiation device pass through a locking nut 24 ( upper and lower) and the silicone ring 26 (upper and lower) which play a sealing role are sealed and connected, and the quartz glass sleeve 23 is provided with a UV lamp 25 for UV irradiation on the flowing water, and the power is 120-750W. There is a water flow channel between the casing...

Abstract

The invention provides a set of device for controlling ozonization byproduct bromate in packaged drinking water, wherein the device is capable of effectively controlling bromate in the packaged drinking water specific to different water qualities and different production capacities, and is used for overcoming the defect that the ozonization byproduct bromate cannot be effectively controlled during the production of the packaged drinking water in the prior art. The device consists of a frame, a UV (Ultraviolet) radiation device and a multipoint ozone dosing device. The device is innovatively characterized in that: multipoint ozone dosage is taken as a core, drinking water is treated by using a bromate control device which integrates UV and an ozone dosing technology, and the ozonization byproduct bromate produced in the water treatment process of bromide-containing raw water is controlled to be less than 10 mug/L while microorganism pollution in the drinking water is effectively controlled, so that finished water meets the Chinese standard requirement; and the device for controlling the ozonization byproduct bromate in the packaged drinking water is economical and practical.

Description

technical field [0001] The invention relates to the technical field of the food and beverage industry, in particular to a bromate control device for ozone disinfection by-products in packaged drinking water. technical background [0002] For a long time, ozone disinfection technology has been widely used in the production of packaged drinking water because of its characteristics of no residue and easy decomposition. However, studies in recent years have found that when the raw water contains bromide, ozone disinfection will produce bromate, a by-product of disinfection. The International Agency for Research on Cancer has classified bromate as a 2B-level potential carcinogen, which has certain genotoxicity at the DNA and chromosome levels. The limit value of bromate in the drinking water standards of the US Environmental Protection Agency, the drinking water quality standards of the World Health Organization, the drinking water quality directives of the European Union, the s...
