Hereinafter, with reference to the accompanying drawings a preferred embodiment of the present invention will be described in more detail.

1 is a view showing the algae generation suppression apparatus applied to the sewage, wastewater treatment water reuse apparatus according to an embodiment of the present invention, Figure 2 is a schematic enlarged view showing the algae generation suppression apparatus in FIG.

Referring to the drawings, the tidal current suppressing device 60 includes a converter 53 of a control panel, a sustain tube 61 installed to electrically apply a negative electrode to the converter 53, and an anode in the sustain tube 61. The copper rod 62 disposed so as to be applied, and copper ions of the copper rod 62 are dissociated into sewage / wastewater, river water, and lake water to be installed in a water-use facility in which algae is expected to be generated.

The algae generation inhibiting device 60 is a water collecting tank 10 for collecting sewage and waste water, a level switch 20 installed in the water collecting tank 10 to sense the level of water, and an electric power of the level switch 20. A transfer pump 30 that is variably driven in accordance with the signal, a flow meter 40 installed in the conduit for instantaneous measurement and integration measurement of the quantity transferred to the transfer pump 30, and a predetermined amount of the pass through the flow meter 40. It consists of a discharge vessel (70) provided with a reaction tank (50) for storing and treating sewage and waste water, and a return pipe (51) opened to the opening / closing valve (52) to be transferred from the reaction tank (50) to the collection tank (10). To the wastewater treatment water reuse apparatus 2;

Sustain tube 61 installed so that the cathode is applied to the reaction tank 50, copper rod 62 disposed so that the anode is applied to the sustain tube 61, and the copper rod is electrically connected to dissociate copper ions The converter 53 is provided in the control panel and is further installed.

The transfer pump 30 is turned on / off by an electrical signal of the level switch 20 to pump and operate to supply water through the conduit 3.

The algae generation suppression device 60 controls a copper rod 62 to which an anode is applied, a susceptor tube 61 to which a cathode is applied, and a cathode and an anode applied to the copper rod 62 and the susceptor tube 61. It is composed of a converter 53 provided in the panel to dissociate copper ions.

Stainless steel pipe (61) is formed of a tube or plate such as iron, SUS, copper, the cathode is applied to dissociate copper ions. That is, the dissociated copper ions prevent or prevent the occurrence of algae in river maintenance, city aesthetics, flush toilets, water reused for cleaning and lake water reused by sewage and wastewater treatment water.

In addition, one or more copper rods 62 are provided in a sustain tube 61 provided with a cathode.

The number of copper rods 62 may be adjusted in order to adjust the concentration of copper ions in the influent. The copper rods 62 and the sustaining tube 61 are arranged at intervals of 1 to 3 cm to ensure the best electrolysis of copper.

The flow meter 40 is installed in the pipeline 3 to the instantaneous flow meter (40-1) and the integrated flow meter (40-2) to control the supply amount of water.

The reaction tank 50 is provided with an algae generation suppression device 60, and dissociates copper ions into the inflow of sewage and wastewater. Treated sewage / wastewater treated with algae generation is converted to water quality having conditions in which algae generation is suppressed, and reused as municipal untreated water, river maintenance water and constant water.

In addition, the copper concentration control by the algae generation inhibiting device 60 adjusts the copper ion concentration by adjusting the electrolysis time by the converter 53 controlled by the control panel.

The sustain tube may be an outer tube or an outer channel, and may be formed of a tube or plate such as iron, SUS, copper, or the like.

In order to control the amount of generation of copper ions (metal cations), the interval between the (+) and (-) poles may be changed or the current and voltage values may be adjusted, which may change the concentration of copper ions in water.

Cu → Cu ^{2 +} + 2e- (anode)

2H ⁺ + 2e- → H ₂ (cathode)

That is, if the voltage or current is excessively increased, the oxidation rate of the copper rod 62 is increased, and thus the copper rod 62 is frequently replaced. Therefore, in large-capacity equipment, the number of copper (copper) rods is increased, and the reactor of the channel type What is necessary is just to install suitably according to site conditions, such as constituting (50).

In other words, the above-mentioned copper ions have a fatal toxicity to the generation and growth of algae, but since an appropriate amount is present in the soil, the water quality standard of the wastewater treatment water is regulated to 3 ppm.

Algae were not generated at a concentration of 0.54 ppm of copper ions in water, and at 1.01 ppm or more, algae that were previously generated are killed, thereby maintaining an inactivation phenomenon.

As described above, when copper ions are dissociated in municipal water, agricultural water, toilet washing water and river water, and lake water, which are used as landscape water such as lake water or river water, fountains and ponds, algae generation is suppressed.
