The present invention seeks to, provide a kind of method that in big flow, water adds chlorine dioxide, the present invention adopts in different periods
With different chlorine residue control parameters, thereby may be ensured that the water yield, may be delayed in the variation increasing or the reduce larger period
Chlorine residue controls and still ensures that the residual chlorine amount of tap water has definite value it is ensured that in the range of standard.
The technical scheme is that, a kind of method that in big flow, water adds chlorine dioxide, it is characterized in that upper water output
Be divided into peak, paddy, at ordinary times；It is provided with two-way chlorine dioxide output channel, the dosing pump of equal regulation of series flow on pipeline, the one or two
Chlorine dioxide addition when chlorine monoxid output channel meets the paddy of upper water output, the second chlorine dioxide output channel meets upper water
The chlorine dioxide addition at ordinary times of output, when two-way chlorine dioxide output channel is fully loaded with the peak meeting upper water output during output
Control the upper limit of residual chlorine amount standard.
Further, the peak period of upper water output controls residual chlorine amount to be not less than intermediate value or lower bound, the Shang Shui of chlorine residue standard
Control during the paddy of output residual chlorine amount be not less than the intermediate value of residual chlorine amount standard or high limit, at ordinary times section range restraint residual chlorine amount be mark
Accurate intermediate value.
Further, peak to section at ordinary times and at ordinary times to the paddy period conversion interval when, control residual chlorine amount be not less than residual chlorine amount mark
Accurate lower bound, paddy to section at ordinary times and at ordinary times to the conversion of peak period interval when, the height of control residual chlorine amount not higher than residual chlorine amount standard
Limit.
Further, control the titanium dioxide chlorine dose that residual chlorine amount is to product water output to be compared, and dioxy is controlled by PLD
Change chlorine output parameter.
The lower bound that chlorine residue controls and high limit are respectively 0.5mg/L and 1mg/L.Intermediate value processes lower bound and the centre of high limit.
The lower bound being controlled according to the countries concerned's standard, chlorine residue and high limit 0.5-1mg/L；It is of course possible to relevant control is set at any time according to standard
Parameter processed.
The device that the chlorine dioxide that the present invention adopts adds, the described device adding includes the first and second agitator tanks, with
The raw material storage tank of the first and second agitator tank cooperations, pipeline, pump, dosing pump, agitator tank is connected with corresponding raw material storage tank, stirring
Groove is commonly connected to reactor by pipeline and dosing pump, and reactor is provided with chlorine dioxide output channel, chlorine dioxide outlet tube
Road is provided with (frequency conversion) output channel, the dosing pump of Flow-rate adjustment that pipeline is connected.
Chlorine dioxide output production capacity be by adjustment equipment feed size, the dosing pump being exported by raw material storage tank Lai
Adjust output.
Beneficial effect：Four-six times of flows output (even more high) when upper water supply flow is paddy when peak, therefore, if
There is two-way chlorine dioxide output channel, the dosing pump of Flow-rate adjustment that pipeline is all connected, the first chlorine dioxide output channel meets
Chlorine dioxide addition during paddy, the second chlorine dioxide output channel meets chlorine dioxide addition at ordinary times, and two-way chlorine dioxide is defeated
Go out pipeline and be fully loaded with the upper limit controlling residual chlorine amount when meeting peak during output.
According to the present invention, make suitable change in chlorine dioxide output device, exported to certainly using two road chlorine dioxide
Water, and segmentation be controlled it is ensured that under the conditions of materials'use is optimized ensure water quality, especially suitable
Upper method for treating water for big flow.
Additionally, according to the present invention, using the existing PID control of dosing pump, by the change of setup parameter it is ensured that omiting
Micro- Delay control still is able to ensure that the chlorine residue of water controls, and therefore chlorine dioxide is readily controlled in low cost.
Specific embodiment
Below, the preferred embodiments of the invention are described in detail.However, the present invention can embody in different forms, no
It is considered as being only limitted to listed embodiment herein.On the contrary, these embodiments are provided can to make disclosed content to this
The technical staff in field fully expresses the scope of the present invention.
In embodiment, the tap water that correspondence carries 10 tons adds chlorine dioxide, typically sets during paddy as 22:30-5:
30, it is 6 during peak：30-8：30,17：00-21：00, remaining period is at ordinary times；Select no chlorine residue parameter control in different periods
System strategy (the possible peak valley of Various Seasonal can adjust at ordinary times)；PLC exports chlorine dioxide according to chlorine residue state modulator dosing pump
Output.Control mode adopts reliable and stable pid control mode.
It is four-six times of flows output (can reach nearly 15 tons of flows per minute) during paddy during peak, therefore, be provided with two-way dioxy
Change chlorine output channel, the dosing pump of Flow-rate adjustment that pipeline is all connected, the first chlorine dioxide output channel meets titanium dioxide during paddy
Chlorine addition, the second chlorine dioxide output channel meets chlorine dioxide addition at ordinary times, and two-way chlorine dioxide output channel is fully loaded with
The upper limit controlling residual chlorine amount during peak is met during output.
The output of upper water be divided into four periods, i.e. the peak of water yield output, paddy, flat, it is remaining that the peak period controls residual chlorine amount to be not less than
Control lower bound, the section range restraint residual chlorine amount chlorine residue standard at ordinary times of residual chlorine amount not low chlorine residue standard when the lower bound of chlorine standard, paddy
Intermediate value；
Peak to section at ordinary times and at ordinary times to the conversion of paddy period interval when, control residual chlorine amount is not less than the lower bound of chlorine residue standard,
Paddy to section at ordinary times and at ordinary times to the conversion of peak period interval when, control residual chlorine amount to be not higher than the high of chlorine residue standard and limit, therefore, pass through
Rationally timesharing area is it is ensured that peak, flat, the uniform chlorination of the timely conversion process of paddy satisfying the criteria.
The amount that residual chlorine amount is to chlorine dioxide output is controlled to carry out the parameter of PLD control.
