Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with embodiment, to the present invention
It is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not used to
Limit the present invention.
Below in conjunction with the accompanying drawings and the application principle of the present invention is further described by specific embodiment.
As it is shown in figure 1, the time controlling ozonator product ozone that the embodiment of the present invention provides controls the throwing of ozone
Dosage finds the method for the optimum dosage of ozone to comprise the following steps:
S101: utilize ozonator be passed through in 1L sanitary sewage respectively 1min, 2min, 3min, 4min, 5min,
The ozone of 6min, question response, through after a period of time, measures water quality index situation of change, determines the dosage of optimal ozone；
S102: be passed through in the sanitary sewage of 1L by the optimum dosage of ozone, measures reacted water quality every 10min and refers to
Mark, determines the optimum reacting time of ozone.
The embodiment of the present invention provides a kind of ozone-submicron bubble-filter method, including: according to the sewage in raw water box
Characteristic, control ozonator and produce time of ozone and control the dosage of ozone, for follow-up ultra micro rice air supporting and filtration
Technique is ready.
According to the water quality situation of sewage in raw water box, if, the water body low containing substantial amounts of Organic substance, dissolved oxygen inside sewage
Smelly situation, then be passed through ozone before submicron bubble；If the content of organics of former water is few, without obvious stink situation, it is not added with
Ozone or add ozone less, prevents ozone from too much killing microorganism in water.
Ultra micro rice air-float method is: by the regulation hydraulic pressure of submicron bubble device, aeration rate so that the air supporting time
Long, the diameter of bubble is little, and corresponding air flotation effect is best.
According to raw water quality, with optimum dosage (2～the 3) min of ozone, optimum reacting time (40～60) min is to former
Adding in water, after ozone adds end, should not immediately enter in submicron bubble device, mainly allow in ozone and water is organic
Thing reaction, increase oxygen in water, play the effect of a pretreatment.Ozone and former water reaction (40～60) min after, start into
Enter submicron bubble technique, the hydraulic pressure of regulation ultra micro rice generator, product bubbles volume so that the diameter of microbubble is minimum, produces micro-gas
The bubble time is the longest, and treatment effect is optimal.
Water after being processed by submicron bubble enters filter by the water inlet pipe of filter, and the filtrate of filter often uses
The sand seen filters.
As in figure 2 it is shown, the embodiment of the present invention provides a kind of ozone-submicron bubble-filtration system, it is provided with ozone and occurs
Device system 1, raw water box 2, submicron bubble generator system 3, filter system 4；
Described Ozonizer system is connected by pipeline with raw water box, produces the time of ozone for controlling ozonator
Control the dosage of ozone, ready for follow-up ultra micro rice air supporting and filtering technique；
Described raw water box is connected by flanged or screw thread aperture pipe with submicron bubble generator system, is used for storing up
Deposit pending sanitary sewage；
Described submicron bubble generator system is connected with filter system, for by regulation submicron bubble device
Hydraulic pressure, aeration rate, change air supporting time and the diameter of bubble, obtain corresponding air flotation effect；
Described filter system water after being processed by submicron bubble enters filter by the water inlet pipe of filter,
Filtered by the filtrate of filter.
The aperture of submicron bubble device is managed and passes through flange between outlet or threaded.
Must being operated when sealing of submicron bubble device.
Submicron bubble device also should include shearing reinforced pipe, and the end of pipe is fixed on the flange of the water cavity pipe of sealing
On.
Below in conjunction with specific embodiment, the application principle of the present invention is further described.
First being passed through ozone in raw sewage, the source of ozone is mainly produced by ozonator, with ozone
Good dosage adds in former water, after adding end, should not immediately enter in submicron bubble device, mainly allows ozone and water
In Organic substance reaction, increase oxygen in water, play the effect of a pretreatment.The sewage that ozone processes stops (40～60)
Min, initially enters submicron bubble technique, the hydraulic pressure of regulation ultra micro rice generator, produces bubbles volume so that the diameter of microbubble is
Little, the product microbubble time is the longest, and treatment effect is optimal.Water after being processed by submicron bubble is entered by the water inlet pipe of filter
Filter, the filtrate of filter uses common sand to filter.In ultra micro rice air-float technology, it is ensured that the sealing of this process is special
The most important, not so it is difficult to produce submicron bubble, does not reaches expected effect.When former water pollutes not serious, can take to add
Air or pure oxygen replace addition ozone, the process of assisted and strengthened aerobic biochemical.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Any amendment, equivalent and the improvement etc. made within god and principle, should be included within the scope of the present invention.
