Abstract
Description
The present invention relates to a caterpillar electrolytic apparatus and a wastewater treatment method using the same, and more particularly, to a caterpillar electrolytic apparatus provided in a treatment tank in a wastewater treatment system comprising an anaerobic tank, an anoxic tank, a treatment tank and a settling tank, And a separation distance between the electrodes can be automatically adjusted so that the voltage can be maintained, and a wastewater treatment method using the same.
Recently, in order to prevent the release of phosphorus (TP), which is the cause of the eutrophication of rivers and lakes and the occurrence of red tide in coastal areas, the government has introduced water quality standard of public sewage treatment facility as 0.2 ㎎ / ℓ More and more economical and efficient technologies are being developed in the processing of phosphorus (TP) as the process is enhanced.
Generally, the removal method of phosphorus contained in the wastewater is an excessive removal of phosphorus in the microorganism from the anaerobic reactor and an excessive absorption of phosphorus into microbial cells by using the energy generated in the oxidation process of the organic material in the aerobic tank, A method in which phosphorus is excessively released by a microorganism in an anaerobic reaction tank, a method in which a mixed solution is separated from a microorganism, and a lime or a metal salt is added to the separated supernatant is removed.
It is known that ammonia nitrogen is removed from the influent water of wastewater by nitrification of nitrate by microbial respiration process of the aerobic tank, and nitrate is reduced to nitrogen gas by transporting nitrate nitrate to anoxic tank.
However, since the biological treatment method is complicated and the reliability of the nutrient removal rate by the active microorganisms is very low, the chemical treatment method of introducing the chemical into the wastewater is performed in order to increase the removal efficiency. However, this method is disadvantageous in that it is expensive, increases the throughput of surplus sludge, and decreases microbial activity when the chemical is continuously supplied.
On the contrary, when iron is used as an electrode for electrolysis in the wastewater treatment, the iron ion generated in the electrode reacts with phosphorus, nitrogen and organic substances in the wastewater to form an insoluble salt, thereby precipitating the wastewater effectively.
Regarding the method of treating wastewater by using electrolysis, Korean Patent Registration No. 10-0490310 discloses a method of treating wastewater with a conventional iron-electrolysis apparatus by removing an anaerobic tank to remove iron- Described is a sewage treatment method using decomposition.
However, since the above method uses a fixed electrode, non-uniform erosion of the electrode occurs, and there is no scale treatment means for reducing the function of the electrode by reducing the treatment efficiency of the pollutant, And it is troublesome to replace the iron electrode after the iron electrode is consumed by the electrolysis.
