Description
Technical field
The present invention relates to public supply mains Systems Sterilizer fields, and in particular to it is a kind of based on intelligent algorithm automatically control
Secondary water-supply ozone disinfection system.
Background technique
The disinfection overwhelming majority of China's urban life drinking water (being commonly called as tap water) is using chlorination method at present.Chlorine disappears
The outstanding advantages of malicious method are that chlorine residue has lasting disinfection, and when chlorine residue is meant with chlorination, chlorination is contacted after a certain period of time,
Remaining chlorine dose in water.Enough residual chlorine concentrations are kept in tap water pipe network system it is ensured that microorganism in tap water
It is controlled in acceptability limit, therefore chlorine residue is one of the critical index of Drinking Water water quality, in standard GB/T 5749-
Clear stipulaties residual chlorine concentration in Terminal tap water has to be larger than equal to 0.05mg/L in 2006 " standards for drinking water quality ".
The passage of residual chlorine concentration at any time can gradually decay, and the attenuation law in water supply pipe net system has obtained more
In-depth study, most common water supply pipe net system residual chlorine concentration attenuation model are first order reaction models, and specific formula is:
Ct=C0·e-k·t, C in formula0For the residual chlorine concentration in tap water beginning in water supply pipe net system, t is tap water in water supply network system
Residence time in system, CtIt is tap water in the residual chlorine concentration after residence time t decaying, e is natural constant, and k is decaying
Coefficient is constant for same section of water supply pipe net system k, can be calculated by the related data detected under prescribed conditions
It obtains.According to the model, after tap water beginning residual chlorine concentration in known water supply pipe net system and its exact residence time, just
The residual chlorine concentration of the tap water after the residence time decays can be calculated.
Secondary water-supply refers to that when civilian be more than the public confession in cities and towns with requirement of the industrial building Drinking Water to hydraulic pressure, water
When water or self-built facility water supply network ability, user or personal way of supplying water are supplied through pipeline by the facilities such as storing, pressurizeing.
Secondary water-supply facility mainly includes water storage apparatus, pressurized equipment and pipeline three parts.Tap water secondary water-supply water storage apparatus (with
Lower abbreviation water storage apparatus) in can stay for some time, if the residence time is too long water storage apparatus export residual chlorine concentration may
Very low level is decayed to, the effect for effectively killing microorganism in water is not had, causes the micro- of the tap water of outflow water storage apparatus
Biological indicators are exceeded.Therefore sterilizing equipment decontaminating apparatus is installed in secondary water-supply facility has great meaning, in the People's Republic of China (PRC)
The 5.3rd article of standard GB/T 17051 " secondary water-supply facility hygienic practice " regulation: " facility must have the position of installation sterilizer, have
The unit facility of condition should be equipped with sterilizer "；People's Republic of China (PRC) professional standard CJJ140-2018 " secondary water-supply engineering skill
Art regulation " Section 6.5 also require, " sterilizing equipment decontaminating apparatus should be arranged in the pond (case) of secondary water-supply facility ", " sterilizing equipment decontaminating apparatus may be selected smelly
Oxygen Generator, ultraviolet ray disinfector, ultraviolet catalytic oxidation equipment and water tank self-cleaning steriliser etc. ".
Ozone generator is mounted in secondary water-supply facility can play supplement disinfection well to chlorination method,
It can solve and recited above asked because tap water microbiological indicator is exceeded caused by tap water overstays in water storage apparatus
Topic, however the problem that how could efficiently and economically use ozone generator can be but encountered in practical applications.Firstly, since
Residual chlorine concentration is enough effectively by within the microorganism killing to acceptability limit in tap water in tap water most of the time, if
It persistently allows ozone generator in the open state, will cause great waste, excessively high maintenance cost and operating cost will be big
The use of big limitation ozone generator.Secondly as the regular hour is needed using ozone generator disinfection, if ozone sent out
Raw device is mounted on the exit of water storage apparatus, is detecting water storage apparatus outlet residual chlorine concentration as low as being not sufficient to ensure that tap water
In microorganism killing to acceptability limit within when just start ozone generator, then or will affect the requirement of user's water,
Disinfection Effect not enough can be influenced due to the processing time, the result is that cannot be in the case where meeting user's water requirement effectively
Play the disinfection of ozone generator.
Summary of the invention
The purpose of the present invention is: by proposing that it is accurate pre- that a kind of intelligent algorithm exports residual chlorine concentration progress to water storage apparatus
It surveys, judges whether the residual chlorine concentration of tap water is enough within microorganism killing to acceptability limit therein with this, so that it is determined that
Ozone generator when is unlatched and closed, and then solves the problems, such as how efficiently economically to use ozone generator.
