After entering the liquid processor, the liquid to be processed is irradiated by the UV lamp, so that bacteria and algae in the liquid to be processed are irradiated by ultraviolet rays to be killed, and the liquid is sterilized and algae-exterminated. The liquid after sterilization and algae removal is discharged from the liquid processor. A seal is provided between the lamp holder and the liquid handler to which the lamp holder is mounted by means of a screw thread or bayonet structure. Sealing of the ultraviolet liquid treatment device is achieved by virtue of the compressive force between the lamp holder and the liquid treatment device and the sealing member. To ensure reliable sealing, prior art ultraviolet liquid treatment devices are also provided with a reminder structure for the user to confirm whether the assembly has been in place, i.e. to effect sealing.
