It is well known that there is a lack of awareness of environmental conservation in the course of rapid economic development. Due to this lack of awareness of environmental conservation, the level of pollution as well as air quality has reached a very serious level. In particular, domestic sewage, agricultural and livestock waste, and industrial wastewater cause pollution of public waters such as appeals, inner bays and inland seas, and urban small and medium rivers.

Therefore, the achievement rate of Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD), which are related to total nitrogen (N) and total phosphorus (P) such as appeal due to water pollution, internal bay and inland sea, are very low. . Moreover, rivers, lakes, and dams are often sources of drinking water, so odors, filter disturbances, and abnormal growth of toxic algae are a major environmental problem.

On the other hand, before industrial development is high, contaminants in household sewage, agricultural and livestock wastewater, and industrial wastewater are mainly organic matter that can be decomposed by certain microorganisms, whereas in recent years, rapid industrial development, population growth, and urban population The concentration of inorganic and organic components in the wastewater is gradually increasing due to the concentration of various waters.In the case of industrial wastewater, chemical oxygen demand (COD) and biochemical oxygen demand (BOD) are required. It contains high concentrations of organic matter such as SS (suspension), nitrogen, and phosphorus.If it flows into rivers, lakes, and dams as it is, it is not only contaminated with water resources such as eutrophication but also destruction of ecosystem due to toxicity. This adversely affects the environment. Therefore, industrial wastewater is set to a certain standard, and is purified to drain below a predetermined standard value.

On the other hand, sewage, such as domestic sewage, is roughly divided into organic and inorganic substances, most of which are organic matter. These organic substances contain three major elements, that is, carbohydrates, fats, proteins, amino acids, etc., and when these organic substances flow into rivers, the streams, etc., cause eutrophication and cause serious pollution.

In order to solve the problems as described above, conventionally, a method of purifying sewage by using anaerobic microorganisms which dislike oxygen is known. However, while the above-described organized anaerobic microorganisms live only in a closed place, the habitat conditions are also difficult, so there is a problem that it is very difficult to maintain them.

On the other hand, in order to solve the above-mentioned problems, a method of purifying sewage using an anaerobic microorganism that can live regardless of the presence of oxygen or an aerobic microorganism that likes oxygen has been known.

In addition, when cleaning the sludge, etc. stacked in the aerobic reaction tank of the water treatment device at regular intervals, the worker inhaled the sludge while inserting a separate hose to the bottom of the reactor while checking the floor. Since it is necessary to clean it while carrying a separate hose, it is not only troublesome due to the transportation of the hose, but also labor force due to the transportation of heavy hoses is increased, and excessive maintenance and maintenance costs are required due to the large number of workers. there was.

The present invention was devised to solve the above-described problems, while installing a bio-ball filled bio tank on an aerobic reaction tank, while installing a rock filter or various fillers (filters) on the filtration tank, the growth and action of microorganisms are prevented. It is an object of the present invention to provide a water treatment apparatus using a bio ball, a bio tank, and a lock filter that can be activated to improve the purification capacity of sewage.

Furthermore, the present invention stabilizes the water treatment performance by activating microorganisms whose activity has been degraded due to environmental changes in the reaction tank, and can easily purify the waste water by the microbial contact oxidation method and the filtration method on the waste water flow path in the water treatment device through a lock filter. It is in a ship.

Another object of the present invention is to provide a water treatment apparatus using a bio ball, a bio tank, and a lock filter, by which an air lift pump is installed in the filtration tank to easily suck and transport the sludge in the bottom of the filtration tank.

In another object of the present invention, a water treatment using a bio ball, a bio tank, and a lock filter is formed to reduce the flow of sewage from being transferred by forming a chamber having a hole formed at a lower portion around a distal end of a transfer pipe flowing into an aerobic reactor. To provide a device.
