Embodiment Construction

[0041] The present invention provides a method for studying the factors affecting corrosion of reclaimed water reuse equipment after disinfection. The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0042] At present, the commonly used disinfectants in reclaimed water reuse include chlorine dioxide, liquid chlorine, ultraviolet rays, ozone, etc., and various disinfection techniques have their own advantages and limitations, among which chlorine disinfection is the most widely used. In the process, the cost is low and the operation is simple, but excessive dosing will produce harmful substances, which will cause corrosion hazards to the water supply pipeline. Therefore, many experts are committed to the research of liquid chlorine disinfection substitutes, among which organic disinfectants have already occupied the field of disinfection In some markets, however, relatively few organic disinfec...

Abstract

The invention belongs to the technical field of equipment corrosion in recycled water reuse and particularly relates to a method for studying disinfected recycled water reuse equipment corrosion influence factors. According to the method, a central composite design and a response surface are used for the first time for studying the corrosion of system equipment by recycled water used as circulating cooling water, relations between the factors influencing the corrosion and actual effects can be expressed visually with the method, the method is different from orthogonal tests, and while a central composite design test method guarantees the remarkable factors, a response surface method is used for visually expressing the influence effect on the corrosion rate between every two factors.

Description

technical field [0001] The invention belongs to the technical field of equipment corrosion in reclaimed water reuse, and in particular relates to a method for studying corrosion-influencing factors of reclaimed water reuse equipment after disinfection. Background technique [0002] Reclaimed water refers to the water that can be beneficially used after the sewage has been properly treated to meet a certain water quality index and meet certain use requirements. The reclaimed water that meets the effluent requirements of the secondary settling tank can be used directly or after further treatment according to different uses. In the industrial process, the most widely used use is industrial cooling water. The reuse of reclaimed water for industrial purposes can not only save water resources, but also solve the pressure of water supply, reduce costs, and effectively prevent environmental pollution. Beijing The daily treatment capacity of reclaimed water reuse can reach 370,000 cu...
