Problems solved by technology

But this invention just stays on the theoretical stage and has not been applied in practical application so far.
And the glass plate loading material in this invention does not have adsorption performance, and the surface area is not big enough, and loading TiO 2 The amount is limited, and the effect of dealing with microbial species and larger quantities of recycled water and rainwater is not very ideal
[0007] For the photocatalytic disinfection application of regenerated water and rainwater in practical applications, there are no reports at home and abroad.
And the UV / TiO with better adsorption performance and larger surface area ACF loaded titanium dioxide 2 There is no report on photocatalytic disinfection reactor

Abstract

The invention discloses a photocatalytic disinfection reactor used for disinfecting reclaimed water and rainwater, a photocatalysis material and a preparation method thereof, an application and an application method thereof. The photocatalytic disinfection reactor comprises a sterilizer case and a disinfection reaction zone. An inlet pipe and an outlet pipe are arranged on the sterilizer case, the sterilizer case comprises a quartz cannula and a stainless steel outer sleeve; the disinfection reaction zone is an annular space formed by between the quartz cannula and the stainless steel outer sleeve, the vertical separator plates are arranged in a disinfection reaction zone every 120mm, the active carbon fiber (ACF) is fixed in the vertical separator plate for loading the nano TiO2 photocatalysis material; a heat suction / radiation fan is arranged at one end of the quartz cannula, and an ultraviolet lamp is arranged in the quartz cannula. On one hand, bacteria in reclaimed water and rainwater can be effectively inactivated, on the other hand, the operation and management of the reactor are convenient, the reactor is safe and reliable, impact and load by a certain water volume can be adapted, in addition, the disinfection reactor has removal effect to an organic matter in water, and safety risk of organism due to bacteria in reclaimed water and rainwater can be avoided.

Description

technical field [0001] The invention belongs to the field of urban sewage treatment and disinfection, and in particular relates to a photocatalytic disinfection reactor for disinfection of regenerated water and rainwater, a photocatalytic material, a preparation method, an application and an application method. Background technique [0002] Urban sewage recycling and rainwater utilization are effective ways to reduce water pollution, improve the ecological environment, and solve the problem of urban water shortage. They have great utilization potential and are strategic countermeasures to solve the problem of water shortage. The possible health risks of the utilization of recycled water and rainwater to human body is one of the current public concerns, especially the microbial risk in the utilization of recycled water. The pathogenic microorganisms that cause harm to human health can be roughly divided into several categories such as bacteria, parasites (parasites and protoz...
