Fig. 2 is the figure of the handling process representing water supply management support system 10.In step 101 (hereinafter referred to as S101), the place sending power limitation information from Utilities Electric Co. or municipality etc. via network obtains information.
In S102, water demand is predicted.As the Forecasting Methodology of concrete water demand, such as there is following methods: provide the place of current and following weather information to obtain information via network from weather bureau etc., contrast with the weather information in past, predict according to process water yield during immediate meteorological figure.Now, be associated to the weather information in major general's past and the process water yield and measurement date and moment, and be kept in not shown water transport history data storehouse (hereinafter referred to as water transport resume DB).The Forecasting Methodology of water demand is not defined to said method, also can be additive method.
In S103, power limitation information and water demand forecasting are input to water transport and use tricks to draw cell 200, to formulate water application plan.
Fig. 3 is the figure of water application plan when to represent in embodiment 1 usual and when electric power is not enough.Especially, when unregulated power limits, become common water transport and use.But, when there being power limitation information, also considering oneself generating equipment of running and the amount of power that produces, judging that whether electric power is not enough, to formulate new water application plan.
Water application plan, except the process water yield, also comprise oneself running control information of generating equipment, the running control information of filtering ponds, the running implemented based on the clean water treatment facility of these information controls.
Based on water application plan in S104, by power control unit 300, running is carried out to oneself not shown generating equipment and control.Oneself is not specially limited by generating equipment, has combustion of fossil fuels to carry out the equipment generated electricity or the equipment etc. that make use of the natural energy such as wind-force, solar energy to drive steam turbine.
In S105, on the impact that the timeliness being subject to processing the water yield changes, and the timeliness change that former water turbidity produces is predicted.At this, the timeliness change of former water turbidity both can utilize water transport to use tricks to draw cell 200 and predict, agglutinant injection rate computing unit 400 also can be utilized to predict.
In S106, select agglutinant injection rate formula by agglutinant injection rate computing unit 400.This is because: there is impact the holdup time of change on the process water in clean water treatment facility 20 of the process water yield, even if agglutinant injection rate is identical with before change, precipitation process water turbidity or filtered water turbidity also can change.Store multiple agglutinant injection rate formula in agglutinant injection rate computing unit 400, at least select according to the former water turbidity measured by turbidimeter 170 or the process water yield.Except above-mentioned former water turbidity, the process water yield, the weather information etc. that can also utilize the water temperature of the former water measured by not shown water thermometer, PH sensor, alkali densimeter, ultraviolet absorbance meter etc., PH, alkali concn, ultraviolet absorbance or provide the place of current and following weather information to obtain from weather bureau etc., select agglutinant injection rate formula, and be not particularly limited.
Fig. 4 is the figure of the example of the agglutinant injection rate formula represented in embodiment 1.In figure, prepare 2 formula (agglutinant injection rate formula a and agglutinant injection rate formula b), running when such as if clean water treatment facility 20 carries out usual, then agglutinant injection rate formula is determined for agglutinant injection rate formula a, if carry out running during electric power deficiency, then agglutinant injection rate formula is determined as agglutinant injection rate formula b.
In S107, based on water application plan, restart common water intaking.
In S108, utilize turbidity 170 to monitor former water turbidity.This is to confirm that the former water turbidity of the short-term of fetching water when restarting increases (flashing effect).
In S109, judge below the setting whether former water turbidity is preserved for agglutinant injection rate computing unit 400.
In S110, the agglutinant injection rate formula used before water intaking changes and carries out running and controls.
In S111, utilize and use tricks to draw water application plan that cell 200 formulated, the data of the loss water level of each sand filtering ponds obtained by loss water-level gauge 190 and filtering ponds by water transport and to operate the data that resume DB600 preserves, filtering ponds operating plan is formulated unit 500 and is formulated filtering ponds operating plan.At this, as the running history data of filtering ponds, filtering ponds running resume DB600 preserves after being associated to the filter run of each filtering ponds of major general, sludge quantity, the loss water level measured by loss water-level gauge 190 and measurement date and moment.Filtering ponds operating plan comprises the running/stopping relevant to each filtering ponds, the information of back scrubbing.Filtering ponds control unit 700, based on filtering ponds operating plan, carries out running to each sand filtering ponds and controls.
In S112, filtering ponds operating plan formulates unit 500 based on filter run so far, dirty load and loss water level, the sand filtering ponds preferentially used when selecting and restart among the sand filtering ponds of stopping that operating.
In S113, based on filtering ponds operating plan, the sand filtering ponds preferentially used when slowly starting to prevent absurd creature restart to the leakage of tap water.
In S114, the sand filtering ponds slowly started with common rate of filtration running.
Finally, in S115, filtering ponds number is increased.Thus, even if also water demand can be tackled in the hypodynamic situation of electricity.
Embodiment 1 supplies with water demand forecasting as the water transport inputted uses tricks to draw cell 200, even if also can realize firmly operating in the hypodynamic situation of electricity by with electric power.Have again, by being selected best agglutinant injection rate formula by agglutinant injection rate computing unit 400, therefore the rising of precipitation process water turbidity can be suppressed, the filter run of sand filtering ponds can be extended and reduce sludge loading amount and have again, also slowly started by the sand filtering ponds preferentially used during selected rerunning, thus the attenuating of water quality grade can be realized.
[embodiment 2]
Fig. 5 is the figure of the water supply management support system represented in embodiment 2.
Being constructed as follows of embodiment 2: possess disinfectant injection rate computing unit and disinfectant injection unit in the water supply management support system 10 of embodiment 1, also contemplate disinfectant outside agglutinant.
Disinfectant injection rate computing unit 800 determines disinfectant injection rate based on water application plan, by the agent that carries out disinfection at well 110 inject (front chlorine process) disinfectant injection unit 810, inject the disinfectant injection unit 820 of (rear chlorine process) implement to inject in clear water reservoir 160 agent that carries out disinfection.At this, disinfectant is liquid chlorine, clorox, calcium hypochlorite and chlorine dioxide etc., is not particularly limited.
The determining method of the disinfectant injection rate in disinfectant injection rate computing unit 800 can be any method, as long as can correspond to electric power deficiency to decide suitable disinfectant injection rate, and is not particularly limited.In the present embodiment, exemplify as one the method deciding the disinfectant injection rate of front chlorine process and rear chlorine process according to the running control information using tricks to draw the process water yield and the filtering ponds made by water transport.
Fig. 6 is the figure of the relation representing the process water yield in embodiment 2 and disinfectant injection rate.If the process water yield reduces, then disinfectant injection rate reduces and increases in rear chlorine process in front chlorine process.As shown in the graph of a relation of Fig. 6, the reason injecting disinfectant is below described.
The change of change on the holdup time of the process water in clean water treatment facility 20 of the process water yield has impact.If the process water yield reduces, then the holdup time increases.In general, the validity being used as the chlorine system disinfectant of disinfectant shows with cl concn, but cl concn is because of the generation of odorous substance and the volatilization etc. from the water surface such as generation, agene (trichloroamine) of the chemical disinfection byproducts such as disinfection reactions, haloform (trihalomethane), passes through along with the time and decrease.As front chlorine process, if inject disinfectant to coagulation sedimentation former water before treatment, then the organic matter that comprises of former water and disinfectant react, and are easy to generate chemical disinfection byproducts and odorous substance.Chemical disinfection byproducts and odorous substance and organic concentration and cl concn proportional, along with the time through and increase, therefore when reducing the process water yield because reply electric power is not enough, the running control that the disinfectant injection rate of front chlorine process is reduced becomes effective.Thus, the generation of chemical disinfection byproducts and odorous substance can be suppressed.But if the disinfectant injection rate of chlorine process before reducing, then the concentration of residual chlorine processed in water reduces, and has the danger that bacterium etc. produces.For this reason, the disinfectant injection rate making rear chlorine process is needed to increase.
Fig. 7 represents the figure of the disinfectant injection rate in embodiment 2 relative to the time variations of the process water yield.As shown in Figure 7, according to water application plan, disinfectant injection rate computing unit 800 pairs of disinfectant injection units 810 and disinfectant injection unit 820 carry out running and control.Although Fig. 7 relates to sand filtering ponds, reality determines for each sand filtering ponds.
Even if when restarting the chlorine according to water application plan after stopped sand filtering ponds and injecting, be also easy to produce odorous substance in front chlorine process.For this reason, when restarting chlorine and injecting as previously mentioned, the disinfectant injection rate of front chlorine process is reduced and the running that the disinfectant injection rate of rear chlorine process is increased becomes effectively.
In example 2, although chlorine process before implementing in well 110, also can implement in the front of well 110, and be not particularly limited.Although chlorine process is implemented in clear water reservoir 160 similarly, also can implement after clear water reservoir 160, and be not particularly limited.Further, in example 2, although implement front chlorine process and rear chlorine process, middle chlorine process can certainly be added.
Although not shown in Fig. 5, after at least confirming, enough sterilization effects are guaranteed in chlorine process, therefore all measure concentration of residual chlorine with chlorine meter the forward and backward or both sides of rear chlorine process.By by chlorine meter the concentration of residual chlorine that measures input to disinfectant injection rate computing unit 800, for the calculating of disinfectant injection rate.
