Description

Disposal device of wastewater

The present invention is for active and effective treatment of sewage containing high influent flow rate and high concentration of organic matter. Especially, it removes finely dispersed pin floc and dissolved fine impurities and turbidity by using adsorption power of charcoal and activated carbon. It is to allow more complete treatment of waste water.

Sewage refers to water that is mixed with liquid or solid dirty materials and cannot be used for human life or industrial activities. It is discharged from flush toilets, baths and kitchens in connection with human daily life. Most dirty materials are organic.

Organic materials are classified into solid materials and soluble materials, and the main purpose of sewage treatment facilities is to obtain clear water by removing organic materials present in such sewage.

The treatment methods of sewage treatment facilities include physicochemical treatments and biological treatments. The physicochemical treatments are mainly pretreatment of sewage treatment facilities, and biological treatments are used to remove soluble substances.

The most widely used biological treatments for wastewater treatment are the most economically available without secondary pollutants, and are classified into aerobic and anaerobic microorganisms according to the type of microorganism.

The aerobic microbial treatment method, which occupies the most important position in sewage treatment, mixes microorganisms requiring oxygen and sewage, induces metabolism of microorganisms, and removes dissolved organic matter and nutrients. Most treatment facilities use activated sludge and long-term aeration methods using suspended growth microorganisms.

Carriers are dozens of materials, shapes, and types due to the development of usage methods, and typical types of small-scale sewage treatment facilities are sedimented and separated from sewage and then transported to a contact aeration tank filled with carriers for oxidation and decomposition. The oil is fed through a settling tank.

These small sewage treatment facilities have a large fluctuation in inflow flow rate and generate high concentrations of organic matters. Especially, small sewage treatment facilities such as living sewage, school feeding facilities, restaurants, etc. are caused by the overgrowth of microorganisms due to the inflow of microorganisms. However, microorganisms do not form hard flocs and are easily proliferated, and microorganisms attached to impact loads due to fluctuations of inflow fluctuations are easily peeled off even with a weak impact.

In addition, the dispersion growth and peeled sludge is poor in sedimentation, causing the function of the sedimentation tank, it is difficult to obtain a clear treated water.

Therefore, there is a problem that the fluctuation range of the inflow flow is large, and active, effective and stable treatment is not easily performed on the sewage containing high concentration organic matter.

The present invention is resistant to load fluctuations (flow rate and concentration) of influent sewage to correct these problems, and introduced adsorption and filtration technology using activated carbon and charcoal having a large surface area to remove pin flocs. The purpose is to provide a high performance sewage treatment apparatus that can process the removal of nitrogen and phosphorus as well as the removal of organic matter, odor, color in the water.

In addition, the present invention further comprises a final aeration chamber for the advanced treatment of sewage after the final sedimentation tank, and filling the carrier with a circular porous PP (polypropylene) network inside the final aeration chamber, the upper and lower divisions Charcoal on one side and granular activated carbon on the other.

At this time, the amount of the carrier to be put into the final aeration chamber is filled with about 30% of the final aeration chamber volume and used as a fluid carrier, and the circular carrier is fixed to the square plate support and used as the adsorption filter of the adsorption filtration tank.

Charcoal and activated carbon introduced into the carrier are porous foams and superabsorbent materials, which are carbon aggregates composed of countless micropores well-developed in each particle, and the micropores are composed of numerous interconnected passages and have a large internal surface area. .

The surface area depends on the suitability of the pore size according to the relative molecular size and the adsorption capacity of charcoal and activated carbon, which is the life of the microorganisms. Denitrification strains and accumulation strains are formed to oxidatively decompose organic matter, nitrogen and phosphorus in contact with sewage.

In addition, these countless holes are all in and out or up and down, so that water and air can easily pass, and the area where water is in contact with the air has a large adsorption force.

By using the adsorption power of charcoal and activated carbon, excellent water treatment is possible by completely treating untreated residual organic matter and suspended matter in sewage.

In order to achieve the above object, the present invention effectively separates solids, oil, and ABS (surfactant) while passing through the oil and water separation plate in the sedimentation tank through the inlet, and thus, the inflow load when entering the flow control tank. I tried to reduce it as much as possible.

In particular, a significant residence time is required to decompose the oil in the water, and the load fluctuation caused by the oil content introduced into the aeration tank is considerably large, and thus, an effective treatment technology for sewage treatment has not been provided.

Therefore, the present invention separates and sediments oil and solids using the oil / water separator plate formed in the sedimentation tank immediately before flowing into the flow adjusting tank, and then flows into the flow adjusting tank and transfers a certain flow rate to the aeration tank by the metering device. The impact of fluctuations was minimized.

In addition, the fixed contact microbial carriers are installed in the first contact aeration chamber and the second contact aeration chamber, and the fluidized bed microbial carrier is installed in the final aeration chamber to actively increase the oxidation efficiency by breeding of aerobic bacteria, and fully oxidized in the contact aeration tank. Wastewater is introduced into the adsorption filtration tank to provide a sewage and wastewater treatment device capable of highly processing by removing residual sludge.

The treatment apparatus is applicable to everything from concrete that can be installed and installed on site to small-scale wastewater treatment facilities that can be transported and installed.

The sedimentation separation of solids and the anaerobic decomposition by sewage retention is prevented at the same time while the sludge flotation is divided into a supernatant, only the supernatant is moved to the rear separation plate (38).

The waste water moved to the rear separator 38 causes the organic matter, which is lighter in weight than water, to be separated and removed.

In other words, the organic matter, especially oils and surfactants, having a specific gravity less than that of the suspended suspended solids of the waste water due to the floating separation through the rear separator 38, floats on the surface and is separated and treated.

As described above, in the sedimentation separation chamber 11, the wastewater flows through the sedimentation and flotation separation by the primary physical treatment, and then flows into the flow regulating tank 12 by natural flow.
