Description of the invention (i) [Technical field to which the invention belongs] (Please read the precautions on the back before filling out this page) The present invention relates to a domestic wastewater or wastewater containing collective ions, such as domestic wastewater Device and method for treating water circulating in tropical fish tank. [Previous technology] One of the reasons for the well-being of rivers or lakes has been known since the early days of the year: the existence of phosphorus compounds. There are many such phosphorus compounds in domestic wastewater in ordinary households, but this phosphorus compound is a substance that is difficult to purify and treat, and there is no effective treatment scheme until now. Various proposals have been made for phosphorus compound treatment equipment. Among them, the electrolytic elution method of iron is known for domestic wastewater (see Japanese Patent Application Laid-Open No. 3.89998, Japanese Patent Application Laid-Open No. 6-254584, c0F 3). / 12). Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economics This technology is a kind of water-insoluble salt that reacts phosphate ions and iron ions in wastewater, such as FeP〇4 or Fe (〇H) x (p〇4) y In order to make it condensed and removed from the temple, the iron strike electrode installed in the electrolytic cell is connected with electricity to make iron ions elute in the drainage. In addition, such a treatment device using an electrolytic stripping method is used in, for example, an anaerobic tank, an aerobic tank, and a processing tank, and the sewage in the processing water tank can be used to elute iron ions that react with phosphorous phosphonium. The electrolysis device is circulated in the sewage treatment device of the anaerobic tank. [Problems to be Solved by the Invention] If the phosphorus removal device according to the above-mentioned electrolytic elution method is used for a long time, a passive film will be generated on the surface of the electrode, which significantly reduces the phosphorus removal performance. Therefore, for example, the device described in the above-mentioned Japanese Unexamined Patent Publication No. 10_43781 adopts the paper size standard.

The treatment device of this embodiment, such as the μ, +, and ^ t garments, is as described above, and can be effectively used for ordinary household wastewater. Therefore, Can be used alone, but It can be used with other purification systems, such as activated sludge method, membrane knife separation method, anaerobic, aerobic peeling ring method, etc. as a comprehensive wastewater purification system for domestic use, collective residences, and shoals. In a large-scale treatment system (molecular urine treatment plant). Next, another embodiment of a water purification device suitable for removing the treatment device for treating water containing phosphate ions according to the present invention from the treated water material of the domain wastewater material will be described. The water purifying device & life-saving device is a device for purifying the water in the water tank by removing organic matter such as feces, urine or leftover bait from the creatures (tropical fish or other fish and shellfish ^ ^ turtles or aquatic insects) raised in the water tank As shown in FIG. 6, the water purification device is composed of a water tank 50 and a filter 51 placed on the upper part of the water tank 50, and the filter 51 has: the lower container 51a The filter trough 52 as the filter section between the cover 51b, the ^^ Lurie 53 provided in the filter and the trough 52, and the Chinese paper standard (CNS) A4 (210x ^^ jy— 310972 (Please read first Note on the back, please fill out this page again) Order ------ Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs's Consumer Cooperatives 6 585840 A7 B7 V. Description of the invention (8) (mm), outer diameter about 6 mm, inner diameter A hollow cylinder of about 3 millimeters is contained in the bag. In addition, in this embodiment, although the decoloring tank is provided on the downstream side of the electrolytic treatment tank, the water purification device of the present invention is not limited to this. Available. Also in this embodiment, the method of arranging the filter tank (filter section) above the water tank will be described, but the filter section may also adopt a filter that can be arranged in the water tank to perform physical filtration and / or biological filtration. Device. Also, this embodiment is adapted to a water purification device, but it can also be applied to a farm or aquarium purification device. [Effects of the Invention] As described above, according to the present invention, since the no-energizing time of the electrode is set by the current-converting device, it can be adhered to the state without electrochemical oxidation or reduction or dissolution or movement of ions. Corrosion products (a FeOOH, etc.) on the electrode surface are aerated and restored to a bulky (α Fe00H) state near the boundary between the electrodes that are being passivated (Fe304) due to lack of oxygen, so you can borrow The corrosion products are peeled off by aeration flow. Therefore, the phosphorus removal performance can be maintained stable. In addition, the non-energizing time of a plurality of electrode pairs is staggered and connected to a constant current power supply, so even if a pair of electrodes becomes non-energized, as long as the entire electrode in the electrolytic cell can still pass a certain amount of current, it is not allowed. Setting the no-power-on time will not cause a reduction in the amount of phosphorus removal. As a result, the phosphorus removal performance can be stably maintained.
