Referring to fig. 1, there is shown a waterway pipe network microorganism control system, which includes a bio-tank 10, a water supply pump 20, a UV sterilizer 30, an ozone generator 40, a level sensor 50, and a water consumption point 60, wherein the bio-tank 10 stores a water source, is finally supplied to the water consumption point 60 by the water supply pump 20, and water passing through the water consumption point 60 is returned to the bio-tank 10 through a recovery pipe, the UV sterilizer 30 is provided between the water supply pump 20 and the water consumption point 60, the ozone generator 40 is provided on the recovery pipe between the water consumption point 60 and the bio-tank 10, and the level sensor 50 is provided in the bio-tank 10.

Wherein used working shaft 20 of system is the frequency conversion working shaft, and the start-stop of frequency conversion working shaft 20 is interlocked with level sensor 50 of biological storage tank 10, and below the liquid level of biological storage tank 10 was in low liquid level LL, frequency conversion working shaft 20 stopped to start, prevented the water pump idle running, until biological storage tank 10 moisturizing to more than low liquid level L, working shaft 20 starts.

Before the system is started, the UV sterilizer 30 is started, the variable-frequency water supply pump 20 is started after the liquid level of the biological storage tank 10 meets the starting condition of the variable-frequency water supply pump 20, the DNA structure of microorganisms (bacteria, fungi and the like) is damaged through the sterilization effect of an ultraviolet lamp in the UV sterilizer 30, the replication of the microorganisms is prevented, and water is produced through the UV sterilizer 30 to provide water quality meeting the standard for the water consumption point 60.

The flow of the frequency conversion water supply pump 20 is Q = Q water and Q circulation, and the Q circulation provides pressure for water flow in the water return pipeline when the water consumption point 60 of the system uses water, so that the system has good dynamic design to realize a turbulent flow state, and the flow rate of the water outlet pipeline and the water return pipeline is more than 1m/s. When the water consumption point 60 is water consumption stopping, the frequency of the variable-frequency water supply pump 20 is controlled by the lowest flow designed by the recovery pipeline flow sensor 90, so that the water outlet and the recovery flow rate meet the positive pressure requirement, and the energy consumption is saved.

The ozone generator 40 is also provided with an ozone reflux valve 41 and an ejector 42, and the ozone generator 40 is connected to a recovery pipeline through the ozone reflux valve 41 and the ejector 42.

On the recycling pipeline, a backwater end ozone detector 70 and a backwater end ozone valve 80 are also arranged between the ozone generator 40 and the biological storage tank 10.

When the water supply system is shut down due to misoperation and system failure, microorganisms are attached to the inner wall of the distribution pipe network, intermittent ozone sterilization needs to be combined at the moment due to the continuous ultraviolet sterilization function, and when the ozone concentration of the ozone detector 70 at the water return end is 0.5ppm, the ozone with the concentration is kept for circularly sterilizing the pipe network for 30-60min, so that microorganisms and bacteria propagated in water are effectively killed, and formed biofilms are effectively degraded.

The working principle of the ejector 42 is that the backwater under the pressure state enters the water inlet end of the ejector 42, the liquid is sprayed out from the nozzle at a high speed, when the liquid flowing at a high speed passes through the gas mixing chamber, vacuum is formed in the gas mixing chamber, a large amount of ozone generated by the ozone generator 40 is sucked in by the gas guide tube, the ozone enters the gas mixing chamber, the ozone and the liquid are violently mixed at the throat to form a gas-liquid mixture, the gas-liquid mixture is discharged by the diffusion tube, and the air rises in the water body in the form of fine bubbles, so that efficient substance transfer is formed in the whole process.

When the ozone detector 70 at the return water end needs to be calibrated or overhauled, the ozone valve 80 at the water supply end is closed, and the ozone detector 70 at the return water end is overhauled or calibrated without stopping the water supply system.

An ozone return valve 41 is arranged in front of the ozone generator and the recovery pipeline to prevent water in the pipeline from returning to the ozone generator 40 and damaging the ozone generator 40.

A return line flow sensor 90 is provided between the water usage point 60 and the ozone generator 40.

The UV sterilizer is internally provided with a plurality of ultraviolet sterilizing lamp tubes. The dosage of the overflowing UV is more than 40mj/cm, and the medium-pressure ultraviolet rays are selected, so that a time accumulation prompting function and an intensity monitoring and alarming function are required.

The medium-pressure ultraviolet output wavelength range is 200-400nm, and the relative output intensity is far higher than that of the low-pressure traditional ultraviolet and low-pressure amalgam ultraviolet lamp tube, so that the tissue structure of microbial cells can be comprehensively destroyed, and the broad spectrum sterilization is better and more thorough.

The ultraviolet dose is used for representing the processing capacity of the ultraviolet water treatment equipment under a certain process condition corresponding to the process condition, the ultraviolet dose (mj/cm) = ultraviolet intensity (mw/cm) = residence time(s), different ultraviolet doses corresponding to different types of microorganisms, molds, viruses and the like, and the overflowing type UV selective dose larger than 40mj/cm2 can cover the dose required by most of different types of microorganisms in water.

The return pipeline of the system is maintained in a positive pressure circulation state, and the water flow in the pipeline is in a turbulent flow state.

The intermittent ozone disinfection needs to be controlled at the concentration of 0.5ppm, and the pipe network is circularly sterilized for 30-60min.

The probe of the ozone detector 70 at the return water end needs to be regularly calibrated and overhauled, so that the measurement precision of the probe of the ozone detector 70 at the return water end is ensured.

The above description is only for the preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention is disclosed in the preferred embodiment, it is not limited to the above description, and any person skilled in the art can make modifications or changes equivalent to the above disclosed technical content without departing from the technical scope of the present invention.
