2, the output terminal of ozone generating-device is communicated with the first ozone interpolation pipeline by the anti-backwater tank of an ozone, and adds in pipeline and be provided with a vacuum breaker at the first ozone, can effectively prevent that the water in pipeline is back in ozone generating-device.
3, the upper end of oxidizing tower connects a Fork LIquid Level Switch, can constantly realize the high liquid level protection in oxidizing tower; Oxidizing tower top is also provided with a respiratory organ and a vacuum breaker, and respiratory organ is communicated with for oxidizing tower is inner and outside air, prevents that oxidizing tower internal pressure from reducing liquid and can't pump out.When respiratory organ is plugged, the air in oxidizing tower also can be more and more rarer, and while approaching vacuum in oxidizing tower, vacuum breaker just can be opened automatically, thereby make oxidizing tower internal pressure and ambient pressure balance, guarantees that the water in oxidizing tower is exported smoothly.
4, process in water return line and be communicated with an on-line cleaning unit by a Hand-operated butterfly valve, the further generation of the bacterium of water in holdout device, particularly stops the generation that absorbed the bacterium in the return line of ozone through Ozone Absorption device.
5, in this device, the filling pressure with the back pressure valve of pressure detection and the use of water point place is associated, pressure in back pressure valve is to change along with the variation of the use point place filling pressure of water, when the filling pressure at the use point place of water becomes large, it is large that the degree that back pressure valve is opened also becomes thereupon, the automatic adjustment of backrest pressure valve, thus form constant voltage circulation.The pressure of processing the recirculation water that the back pressure valve in water return line detects according to it, the flow in pilot piping, controls the output flow of processing the transferpump in water delivery pipe road, makes that filling amount is relative with supply mates.
6, Ozone Absorption device adopts uv-absorbing, the ozone decomposed in recirculation water can be become to oxygen, thus stop recirculation water again with ozone contact, thereby the generation of effectively stopping bromate.

First, ozone generating-device 1 produces ozone, the first gas and water mixer 20 that ozone adds in pipeline 2 through the first ozone mixes with the water of not processed mistake, after mixing, passed in oxidizing tower 4 and carried out abundant combination treatment again by the spray ball 43 in oxidizing tower 4, processing water after treatment separates two-way from oxidizing tower 4.The first via passes into oxidizing tower 4 after again mixing with ozone by the second gas and water mixer 31 in the second ozone interpolation pipeline 3 again, wherein, the content that the second ozone adds the ozone in ozone content that pipeline 3 adds detects oxidizing tower 4 outputs processing water according to the first ozone on-line measuring device 34 is adjusted.Carry by processing water transfer line 5 on the second tunnel, process water transfer line 5 and there is the online detection branch of ozone, in the online detection branch of ozone, connect the second ozone on-line measuring device 57, process water transfer line 5 and there are three output terminals, the second ozone on-line measuring device 57, determines to process water according to the result of its detection and is transported to some output terminals.The first output terminal is to lead to relief outlet, and the second output terminal is the use point-filling point that leads to water, and the 3rd output terminal is to lead to process in water return line 6.When detect processing water-ozone too high levels time, processing water is sent into the first output terminal; When the processing water-ozone content detecting is qualified, processing water is conveyed into the second output terminal; When the processing water-ozone content detecting is between qualified and defective, processing water is sent into the 3rd output terminal.Process in water return line 6 and be provided with back pressure valve 60 and Ozone Absorption device 61, the degree of cut-offfing of back pressure valve 60 is relevant to the force value at filling some place, when the use of water is put 55 places while being greater than required filling water for filling water, be that filling amount is while being less than supply, open the second Pneumatic butterfly valve 53, unnecessary water is delivered to and is processed in water return line 6, the pressure of the recirculation water that the back pressure valve 60 in processing water return line 6 detects according to it, flow in pilot piping, the output flow that makes to process the transferpump 50 in water delivery pipe road reduces relatively, make that filling amount is relative with supply mates.Recirculation water after 60 reduction of Ozone Absorption device is sent in oxidizing tower 4 again.When the recirculation water being reduced, deliver in oxidizing tower 4, can cause the liquid level in oxidizing tower 4 to jump, the interior ozone content of oxidizing tower 4 changes, and now just need to open the second ozone interpolation pipeline 3 and carry out ozone inching again.
For above-described embodiment, the issuable variation of the present invention is described below:
All the other are same as the previously described embodiments, and difference is, process the recirculation water of processing through Ozone Absorption device 60 in water return line 6 and can also be communicated in pending water, re-start mixing wastewater with air, saving water carries out disinfection.
Above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that spirit is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
