[0001] Electrolytic type wastewater treatment apparatus [0002]

The present invention relates to an electrolytic water treatment apparatus, and more particularly, to an electrolytic water treatment apparatus which does not have a housing of a separate electrolysis apparatus and does not leak water to the outside to improve the purification efficiency of contaminants against polluted water, To a decomposition type water treatment apparatus.

In recent years, due to the large population growth and industrial development, there is an absolute shortage of water resources, and a large amount of sewage and industrial wastewater is discharged per day. As a result, water pollution is becoming a serious social problem.

In particular, domestic sewage, livestock wastewater, industrial wastewater, and the like are polluting water quality in public waters and small and medium rivers.

The pollutants of domestic wastewater, livestock wastewater and industrial wastewater are mainly organisms which can be decomposed by specific microorganisms. Recently, due to rapid industrial development, population increase and concentration of population of the city, The proportion of inorganic and organic components is gradually increasing.

The standard activated sludge method using the floating growth of microorganisms is widely used as a method for treating existing sewage, livestock wastewater, and industrial wastewater.

However, the conventional biological treatment method has a problem that not only the reaction speed is slow, but also the treatment efficiency is low and an additional advanced treatment facility must be provided.

Therefore, recently, physico-chemical treatment methods having higher treatment efficiency and higher rate than biological treatment methods have been studied, and a treatment method using electrolysis has been emphasized.

The above-mentioned electric treatment method will be briefly described. First, the treated water to be treated to have a higher efficiency in the electrolytic bath is put into a conditioning tank, which is a pretreatment process, and then caustic soda, an inorganic flocculant and appropriate additives (Nacl, Na2so4) And a pre-treatment step of adjusting the conductivity by mixing.

Thereafter, the treated water having undergone the conductivity adjusting step is passed through the electrolytic bath to induce the electric reaction, and the impurities contained in the treated water due to electrocoagulation, electroflation, and electrooxidation The filtered water is discharged, and the suspended matters generated in the treatment process are transferred to the suspended-matter storage tank, and the precipitated aggregate is discharged through the discharge pipe.

There is a process of electrolyzing treatment water that has undergone a pretreatment process in an electrolytic bath, and an example of a water treatment apparatus using existing electrolysis is disclosed in Korean Patent Publication No. 10-2012-0069213 entitled " "Has been filed and published.
