Also have, in the present embodiment, send into electrolyzer 10, so when electrolysis treatment began, pH was suitable for electrolysis treatment owing to will in baffle-box 20, adjust the processed water of pH in advance.Thus, can avoid influence, the situation that the removal efficient of the nitrogen compound of this electrolysis treatment reduces because of pH.
Have, the viewpoint from the easiness of price, circulation, processing etc. it is believed that best chloride ion case 31 chemical agents that supply with, supply with chloride ion in solution are sodium-chlor, but the present invention is not limited to this again.In addition, as adjust agent case 32 chemical agents that supply with, that be used to adjust pH by pH, consider price and circulation etc., such as, can enumerate the vitriol oil and/or sodium hydroxide, in addition, owing to must supply with chloride ion to the processed water in the baffle-box 20, so also can enumerate hydrochloric acid.
In addition, adjust the occasion that hydrochloric acid is adopted in agent, can form by the distinctive scheme of the water treatment device of present embodiment at pH.That is, in the water treatment device of present embodiment, the interpolation of the pH of processed water adjustment agent is carried out according to the mode that the electrolysis treatment with electrolyzer 10 walks abreast relatively.So even carry out in the scope of long slightly time under the situation of the interpolation that pH adjusts agent, the beginning of the electrolysis treatment of electrolyzer 10 does not still postpone therefrom.Can pH be adjusted agent make an addition in the processed water at every turn with less amount thus.Because the such formation of water treatment device is in the water treatment device of present embodiment, usually, the hydrochloric acid that has the problem of white cigarette when making an addition in the processed water is at every turn to add more on a small quantity, thus, suppress the generation of this white cigarette with doing one's utmost, can be used as pH adjustment agent thus and use.
The 3rd embodiment
Fig. 5 is the figure of the structure of the water treatment device of representing present embodiment in a schematic way.The water treatment device of present embodiment is as shown in Figure 5, and the water treatment device of relative the 2nd embodiment replaces the chloride ion concentration transmitter in the baffle-box 20, and the Conductivity Meters that detects the electric conductivity of sending into the processed water in the baffle-box 20 is set.
Fig. 6 represents the controlling party block diagram of the water treatment device of present embodiment.The water treatment device of present embodiment is identical with the water treatment device of the 2nd embodiment, the building block with control part 40 grades.In addition, the water treatment device of present embodiment is compared with the water treatment device of the 2nd embodiment, replaces chloride ion concentration transmitter 22, and Conductivity Meters is set.The detection of this Conductivity Meters 33 is input in the control part 40.
Relatively in the water treatment device of the 2nd embodiment, situation about determining is exported in detection according to chloride ion concentration transmitter 22, in the water treatment device of present embodiment, the addition of the chloride ion in the baffle-box 20 is determined according to the detection output of Conductivity Meters 33.
Specifically, in storer 41, shown in storing in Fig. 7 in a schematic way, the detection of Conductivity Meters 33 output (electric conductivity) and in processed water, comprising, relation between the nitrogen compound concentration of estimating (nitrogen compound predicted concentration), and in Fig. 8 shown in a schematic way, nitrogen compound predicted concentration and should make an addition to relation between the amount of the chloride ion in the baffle-box 20.In addition, Fig. 7 represents if electric conductivity increases, then according to its proportional substantially mode, the situation that the nitrogen compound predicted concentration increases.In addition, Fig. 8 represents if the nitrogen compound predicted concentration increases, then corresponding to this, and the situation that the amount of the chloride ion that should add increases.In addition, control part 40 is according to the electric conductivity of the detection of Conductivity Meters 33, with reference to storer 41, calculate the nitrogen compound predicted concentration, and then, according to this nitrogen compound predicted concentration, the amount of the chloride ion that calculating should be added is with the addition of this calculation result as chloride ion.
In the present embodiment, replace the chloride ion concentration transmitter of the 2nd embodiment, and adopt Conductivity Meters.In order to determine nitrogen compound concentration, with according to a certain degree, be that certain situation is as its condition with the composition of sending into the processed water of baffle-box 20 according to Conductivity Meters.But, because the price of Conductivity Meters is lower than the chloride ion concentration transmitter, so in the occasion that water treatment device is provided with for the processed water that satisfies such condition is handled, can adopt present embodiment such, with the low water treatment device that constitutes of price.
Should think that this disclosed each embodiment is exemplary, is not restrictive aspect whole.Scope of the present invention is by top description, and provides by the scope of claim, should comprise the implication of the scope that is equal to claim and the whole change scheme in this scope.In addition, disclosed technical scope both can be implemented individually in each embodiment, and mode also capable of being combined under the possible situation is implemented.
