Description

WATER CONTROL SYSTEM FOR SEWAGE PURIFIER}

The present invention relates to a device for controlling the amount of wastewater flowing into the contact aeration chamber of the sewage purification apparatus for purifying wastewater, such as manure and domestic sewage, and in particular, the amount of wastewater as a float descending by buoyancy It relates to a water purification device for a septic tank.

In general, when the waste water discharged from the home or dining room, such as manure or domestic sewage is discharged into the river as it is the cause of water pollution, a lot of means have been developed for discharge after purification treatment.

In the cylindrical tank, the first and second anaerobic tanks, the contact aeration chamber, and the settling chamber are sequentially partitioned by respective partition walls, and the settling chamber and the filtration cracking chamber penetrated are installed above the first and second anaerobic tanks.

In the conventional sewage purification apparatus having the above configuration, the wastewater introduced into the tank from the outside is introduced into the contact aeration chamber after the precipitation and anaerobic decomposition are performed in the first and second type aerobic tanks, and the wastewater introduced into the contact aeration chamber is the contact member installed therein. Decomposition reaction of organic material is carried out by aerobic microorganisms, so it is introduced into sedimentation chamber after organic material is removed, and wastewater introduced into sedimentation chamber is accumulated sludge in the lower part by its own weight, and then it is filtered through the upper part. Inflow.

The wastewater flowing into the filtrate chamber is filtered and decomposed while the remaining untreated matter is passed through the filter medium again.

In particular, the wastewater purification apparatus is to remove the organic material contained in the waste water because a large amount of microorganisms are attached to the contact plate installed in the contact aeration chamber.

However, the amount of wastewater, such as manure and household sewage discharged from homes and restaurants, varies greatly depending on the time and time. If it is not moved to the next step, or if too little wastewater is introduced, there is a problem that the microorganisms die due to nutritional imbalance due to the lack of organic material as a source of microorganisms.

In order to solve such a problem, there is a utility water registration application No. 97-7689, 'water purification device for septic purification tank' filed by the applicant.

The design of the first application is a 'purification apparatus in which the first and second anaerobic tanks, the contact aeration chamber, the precipitation chamber, and the filtration cracking chamber are sequentially installed in the tank. The inlet pipe is installed inside the tank so that the inlet pipe is penetrated with the second anaerobic tank and the outlet pipe is penetrated with the contact aeration chamber. The reservoir wall with a passage at the bottom and the overflow wall with a passage at the top and the outlet at the top are formed. The metering wall is built up and installed in the water reservoir sequentially, and a water return valve is installed in the water quantity control room between the metering wall and the overflow wall, and the water pump is installed in the inlet pipe. The amount of wastewater entering the chamber is controlled.

However, the above-described design of the present application is to transfer the wastewater of the second anaerobic tank to the contact aeration chamber using an underwater pump, and the following problems have been raised.

first ; As the submersible pump was continuously operated, only the required amount of waste water was introduced into the contact aeration chamber and the rest was circulated back to the second anaerobic tank.

second ; Since wastewater contains various foreign substances due to its characteristics, failures such as the rotary blades of submersible pumps being damaged by foreign substances or clogging the pipe to which the waste water moves,

third ; Since the submersible pump must be installed in the water of the second anaerobic tank, there is a problem that its work is difficult when installing, troubleshooting or checking.

fourth ; In order to prevent idling of the submersible pump, it is necessary to install a separate switch for detecting the water level falling below a certain value. If such a switch does not operate due to a malfunction, it causes a failure of the submersible pump.

The present invention has been researched and developed in order to solve the above problems, there is a technical problem that the amount of wastewater flowing into the contact aeration chamber is kept constant in the initial control state.

Another technical problem of the present invention is to allow the wastewater to flow into the water quantity control device by the air pressure introduced from the outside, so that there is no breakdown point and easy maintenance.

Another technical problem of the present invention is to move the wastewater by the air pump instead of the water pump as in the prior art so that it can be operated with less power.
