Description of the invention () Room 34 transfers water. The water dividing chamber is divided into two chambers, namely the first water dividing chamber 35 and the second water dividing chamber 36. In addition, the lower end of the wall between the first water dividing chamber 35 and the middle chamber 34 is fixed to the bottom plate, and the upper end is opened to form V shape. The lower end of the wall between the second water distribution chamber 36 and the middle chamber 34 is fixed to the bottom plate, and the upper end is opened in a concave shape. Then, an overflow weir plate is installed on the wall between the open and concave shapes to adjust its opening size. An outflow pipe 37 is connected to the first water distribution chamber 35 to allow the treated water to flow out to the circulation path 26, and an outflow pipe 38 is connected to the second water distribution chamber 36 to allow the treated water to flow out to the biofilm filter tank 10. Therefore, The treatment water flowing into the inflow chamber 33 is adjusted by the first adjustment of the height of the overflow weir plate through the intermediate chamber 34. The water chamber 35 distributes water to the circulation path 26 and the biofilm filter tank 10. The dephosphorization treatment device includes a dissolution tank 39, four sets of iron electrodes 40 · 41 of rectangular plates arranged in the dissolution tank 39, and supplies these electrodes 40_41 The direct current power supply 42, the control unit 43, and the switch 44 of the current. In addition, iron is used for the anode and cathode of the electrodes 40. 41. The treated water flowing from the outflow pipe 37 is stored in the dissolution tank 39. Four sets of iron electrodes 40. 41 are used. Electrolytic decomposition dissolves iron ions that react with phosphoric acid. The control unit 43 controls the amount of ion dissolution in the dissolution tank 39 by controlling the current supplied to these electrodes 40 · 41. The dissolution tank 39 is provided above the biofilm filtration tank 10 and The front and back plate portions, the left and right side panel portions, and the bottom plate portion are integrated into a rectangular box-shaped bottomed structure. Inflow and outflow tube portions are respectively provided on the front and back plate portions. As shown in FIG. 3, in the dissolution tank 39 Install 4 sets of electrode units 47, inflatable tube 4S for inflating these electrode units 47, and 9 GB of paper (CNS) Λ4 standard Γ210 × 297 mm for paper inflation. 1 (Please read the back Note again Shoe page) installed. • Bureau of Standards set employees Traditional Indian Economic Co-op 425377 A7 B7 five portions described () 45 of the air supply pipe arranged outside the tank blower 46 of the invention. Each electrode unit 47 is formed by arranging a set of electrodes 40 and 41 facing each other at a fixed interval, and fixing the upper part of the electrodes to the holder 48. As described in more detail with reference to FIG. 4, the holder 48 is composed of a set of electrodes 40 · 41 and a terminal lower holder 49 and a cover on the lower holder 49 and embedded in the upper holder 50. The lower holder 49 and the upper holder 50 are integrated with two fitting claws 50a provided in the upper holder 50, respectively, fitted into two fitting holes 49a provided in the lower holder 49. The holder 48 of each electrode unit 47 is provided with a connecting convex portion 47a and a connecting concave portion 47b. As shown in FIGS. 5 and 6, one electrode unit 47 is inserted into the recessed portion 47 b of an adjacent electrode unit 47, and at the same time, the recessed portion 47 b of the electrode unit 47 on one end side is fitted into the convex portion 51 a of the convex member 51. The convex portion 47a of the electrode unit 47 on the other end side is fitted into the concave portion 52a of the concave member 52 and fixed to the dissolution tank 39 to obtain a desired number of electrode unit 47 strings. To dissolve the iron in the dissolution tank 39, a constant current decomposition method using a direct current polarity inversion (DC-PR) method is used to prevent passivation (iron becomes insoluble). Passivation occurs at the anode due to an oxide film covering the surface of the electrode, but at the cathode, the surface of the electrode is always washed due to the occurrence of hydrogen. The use of polarity reversal provides the opportunity for both electrodes to become cathodes. It can make passivation less likely to occur. In addition, due to the polarity reversal, both electrodes are dissolved uniformly, and the electrodes can be replaced at the same time. The time for this polarity reversal is preferably 1 hour or more. When it is set too short, for example, the polarity is switched at 5 second intervals (please read the note on the back ^ > and then fill out this page).

When the invention is described (), the current does not dissolve. For the electrical decomposition, a DC pulse constant current electrical decomposition method may be used. In this case, an insoluble electrode made of a metal such as silver or platinum is used on one side (cathode), and an iron or aluminum electrode is provided on the other side (anode). As a countermeasure against bluntness, a pulse wave that occasionally supplies a large amount of current is used. A blower 46 disposed outside the tank supplies air from an inflatable tube 45 disposed transversely to the lower part of the electrode unit 47 to supplement the treated water to reduce dissolved oxygen. That is, when iron dissolves, it ionizes into divalent iron ion Fe + 2, but in order to react with orthophosphoric acid P04-4, 'need trivalent iron ion Fe + 3' to change from Fe + 2 to oxidation. This is done by treating water The dissolved oxygen is carried out. If there is no dissolved oxygen, the eluted iron will remain Fe + 2 and will not react with orthophosphate P04. Therefore, by inflating from the inflatable tube 45, dissolved oxygen in the treated water is replenished. In the dissolution tank 39, iron ions Fe + 2 are dissolved from the electrodes 40 and 41, and oxygen in the treated water is supplied from a gas pipe 45. Fe + 2 is oxidized with dissolved oxygen, and is sent to the inclusion removal tank 4 while becoming Fe + 3. It reacts with orthophosphoric acid P04-3, and becomes insoluble Fe (OH) X (P04) y. The ferrophosphoric acid salt Fe (OH) x (PO4) y is aggregated by using SS present in the inclusion removal tank 4 as a core, and it becomes a large block, which precipitates and accumulates at the bottom of the tank. A power source 42 such as DC-PR electrical decomposition is installed outside the tank. The power source 42 is controlled by the control unit 43. A voltage sensor 53 is connected in parallel between the power source 42 and the electrodes 40 · 41 as a detecting part for detecting a voltage change between the electrodes, as shown in FIG. 7. In addition, in theory, according to Faraday's law, the elution of iron ions 11 paper sizes are applicable to Chinese National Standard (CNS) A4 specifications (210X297 mm).

Description of the invention () The quantity is determined by the current, and the electrode is supplied with a constant current. When the electrolysis is performed to dissolve the iron, the electrodes 40 · 41 dissolve and gradually decrease. However, since the electrodes 40 · 41 are supplied with a constant current, the voltage supplied to the electrodes 40 · 41 increases as the iron dissolves. When the voltage sensor (detection unit) 53 detects that the voltage between the electrodes has become predetermined due to the voltage rise, the control unit 43 causes the electrode consumption notification lamp (not shown in the figure) provided as a visual notification unit outside the tank. When the light is on, the replacement time of the electrodes 40 · 41 is notified, and in order to prevent the voltage from rising, a constant voltage is applied to the electrodes 40 · 41. If the voltage requirement at this time is set to about 20V, the risk of electric shock to the human body will be reduced. Between the maintenance commissioned by the user and the replacement of the electrode, a constant voltage is applied to the electrode 40 · 41. As the surface area of the iron electrode 40 _ 41 decreases due to dissolution, the current flowing through it decreases. According to Faraday's law, the dissolution of iron ions The amount is reduced, but the reduction of phosphorus removal performance can be suppressed. It is also possible to adopt a structure. If the voltage between the electrodes becomes 20V, the electrode consumption notification lamp is turned on, and a constant current is continuously supplied. If it rises to 25V, a constant voltage lower than 25V is applied to the electrodes 40 and 41. When using the dephosphorization treatment device D structured as described above to perform a predetermined constant current electrolysis method, the voltage between the terminals of the electrodes 40 (41) (voltage between electrodes) (V) and the electrode consumption rate (reduction ratio of the surface area of the electrodes) (%) The relationship is shown in Figure 8.

Description of the invention () The rate is about 710/00. Secondly, the description is best attached to the dephosphorization treatment. Elements of device D and their functions. Regarding the rules for selecting a septic tank, the size of the septic tank is not determined based on the actual amount of water flowing in or the quality of the water, but is determined based on the "Estimation Criteria for Treatment Objects of Toilet Sinks for Different Purposes of Buildings = JIS A 3302". That is, the estimation standard of the person to be treated in the purification tank is based on the situation of the house n = 5 + (A — 67 / 3〇) η: Person (person) A: The total floor area of the building (m2) However, A is 67 m2 or less It is set as 5 persons at time, and it is set as person when A exceeds 220m2. Personnel estimation methods in accordance with this JIS are often impractical. For example, when the floor area of a building exceeds 220m2, in fact, only 2 people need 10 people. In this case, when a person who has obtained the iron elution amount based on the estimation standard based on JIS determines that the iron dissolution amount exceeds the required amount. In addition to reacting with phosphoric acid, iron also reacts with the hydroxyl group 0H-, and ferric hydroxide also becomes a poorly soluble salt, which accumulates in sludge. Therefore, when the iron is excessively dissolved, the sludge of ferrous hydroxide increases, causing problems such as the number of times that the sludge is drawn out (the number of cleaning tank cleanings), or the consumption of more electricity than necessary to dissolve the iron becomes uneconomical. Therefore, it was decided to set a switch for controlling the amount of iron dissolution in accordance with the number of people in actual use. This prevents the amount of ferrous hydroxide sludge from increasing due to excessive dissolution of iron, which increases the number of times that sludge is drawn out, and can save electricity costs.

When the treated water flows into the dissolution tank 60, the electrodes 61 and 62 are energized. Supply current during normal operation so that Fe / P = 1.5. Then, after the normal operation is performed for a fixed time (12 hours), the phosphate ion concentration of the treated water stored in the detection tank 69 is measured with a phosphate ion concentration sensor 73. If the measured phosphate ion concentration is 1.0 mg / L or more, the actions are roughly divided into two types. That is, if the phosphate ion concentration is 1.0 mg / liter or more and less than 9.0 mg / liter, a current is supplied so that Fe / P = 2.0. If the phosphate ion concentration is 9.0 mg / L or more, a current is supplied so that Fe / P = i.5 °. Then, when the voltage between the electrodes detected by the voltage sensor 71 is 25 V (reference value) or more, When the control unit 64 instructs the notification unit 68 to turn on the LED light, the inspection time of the notification electrodes 61 · 62 has arrived (warning display is ON) ° When the phosphate ion concentration of the treated water stored in the detection tank 69 does not change significantly for a long time, For example, when the current is supplied so that Fe / P = 1.5 to 2.0, and the concentration of the phosphate ion does not change compared to the initial value, the inspection period of the electrode 61 · 62 is also the same.
