The invention relates to a method and device for re-circulating disinfection of drinking water by using waste ozone. The method comprises six steps of disinfecting with ultraviolet rays; continuously mixing, dissolving and decomposing a gas-water mixed flow in the drinking water; and disinfecting a tank body, the drinking water in the tank body and air in the tank body. The device comprises the tank body, a plurality of ultraviolet lamps, a plurality of quartz socket tubes, a water ejector, and a high pressure water pump. The tank body comprises a first cavity, a second cavity communicated with air and a water cavity; the quartz socket tubes sealingly penetrate through the left and right walls of the water cavity and open in the first cavity and second cavity; the ultraviolet lamps sealingly penetrate through the first cavity and are disposed in the quartz socket tubes; a pressure water inlet of the water ejector is communicated with a high pressure water outlet of the high pressure water pump; a nozzle of the water ejector is communicated with the water cavity; and a gas inlet of the water ejector is communicated with the first cavity. The method and device take full use of conventional equipment and waste ozone byproducts, carry out ozone deep disinfection on the drinking water again, and save energy.

The invention relates to a control method of an intelligent laser code-spraying system for plastic pipelines. The control method of the intelligent laser code-spraying system for plastic pipelines comprises the following steps that a microprocessor is connected with a laser code-spraying system, an ERP, an anti-fake tracing module, a system software linkup platform, a production detection system,an auxiliary machine, and a laser code-spraying self-inspection system; the microprocessor is connected with an ERP ordering module of a code-spraying manufacturer (to inquire an anti-fake data code required to be automatically generated by the code-spraying manufacturer; the microprocessor is in butt joint with system software of the code-spraying manufacturer and is connected with a photoelectric camera of the production detection system (to compare the existence of code-spraying information, and the position, height, color and luster of a product); the microprocessor is in butt joint with an ultrasonic thickness measurement and weight-per-meter system (to detect whether the walls of the plastic pipelines have defects or not and to detect the concentricity and ovality of the pipelines);and the microprocessor is connected with a pre-judgment and error reporting system of a laser code-spraying machine (to ensue the normality and integrity of laser code-spraying). By adoption of the control method of the intelligent laser code-spraying system for the plastic pipelines, an anti-fake effect, order code-spraying of the ERP system, production detection, error reporting, and code-spraying detection of the plastic pipelines are achieved, and intelligent laser code-spraying of the plastic pipeline is achieved.
